Investigating the Efficacy of an Individualized Alpha/Delta Neurofeedback Protocol in the Treatment of Chronic Tinnitus
Authors: Güntensperger Dominik , Thüring Christian , Kleinjung Tobias , Neff Patrick , Meyer Martin
Published: March 2019

First attempts have demonstrated that the application of alpha/delta neurofeedback in the treatment of chronic tinnitus leads to a reduction of symptoms at the group level. However, recent research also suggests that chronic tinnitus is a decidedly heterogeneous phenomenon, one that requires treatment of distinct subgroups or even on an individual level. Thus, the purpose of this study was to evaluate an individually adjusted alpha/delta neurofeedback protocol. Following previous studies, the delta band fixed between 3 and 4 Hz was chosen as the frequency for inhibition. However, unlike the previous studies, the frequency range for the rewarded alpha band was not fixed between 8 and 12 Hz but rather individually determined according to each patient’s specific alpha peak frequency (IAF). Twenty-six chronic tinnitus patients participated in 15 weekly neurofeedback training sessions and extensive pre- and post-tests, as well as follow-up testing 3 and 6 months after training. The main outcome measures were tinnitus-related distress measured with the Tinnitus Handicap Inventory (THI) and Tinnitus Questionnaire (TQ), tinnitus loudness, and pre- and post-training resting-state EEG activity in trained frequency bands. In Results, the neurofeedback protocol led to a significant reduction of tinnitus-related distress and tinnitus loudness. While distress remained on a low level even 6 months after the completion of training, loudness returned to baseline levels in the follow-up period. In addition, resting-state EEG activity showed an increase in the trained alpha/delta ratio over the course of the training. This ratio increase was related to training-induced changes of tinnitus-related distress as measured with TQ, mainly due to increases in the alpha frequency range. In sum, this study confirms the alpha/delta neurofeedback as a suitable option for the treatment of chronic tinnitus and represents a first step towards the development of individual neurofeedback protocols. This clinical trial was registered online at ClinicalTrials.gov (NCT02383147) and kofam.ch (SNCTP000001313).

Published: March 2019

Purpose. Different microRNAs (miRs) have been demonstrated to relate with the outcome of glioma patients, while the conclusions are inconsistent. We perform a meta-analysis to clarify the relationship between different miRs and prognosis of glioma.Methods. Related studies were retrieved from PubMed, Embase, and Cochrane Library. Pooled hazard ratios (HRs) of different miRs expression for survival and 95% confidence intervals (CIs) were calculated using random-effects model.Results. A total of 15 miRs with 4708 glioma patients were ultimately included. Increased expression of miR-15b (HR, 1.584; 95% CI, 1.199-2.092), 21 (HR, 1.591; 95% CI, 1.278-1.981), 148a (HR, 1.122; 95% CI, 1.023-1.231), 196 (HR, 1.877; 95% CI, 1.033-3.411), 210 (HR, 1.251; 95% CI, 1.010-1.550), and 221 (HR, 1.269; 95% CI, 1.054-1.527) or decreased expression of miR-106a (HR, 0.809; 95% CI, 0.655-0.998) and 124 (HR, 0.833; 95% CI, 0.729-0.952) was correlated with poor outcome of glioma patients.Conclusions. miR-15b, 21, 148a, 196, 210, 221, 106a, and 124 are valuable biomarkers for the prognosis of glioma which might be used in clinical settings.
MI‐Based Robust Waveform Design in Radar and Jammer Games
Authors: Wang Bin , Chen Xu , Xin Fengming , Song Xin
Published: March 2019

Due to the uncertainties of the radar target prior information in the actual scene, the waveform designed based on the radar target prior information cannot meet the needs of parameter estimation. To improve the performance of parameter estimation, a novel transmitted waveform design method under the hierarchical game model of radar and jammer, which maximizes the mutual information (MI) between the radar target echo and the random target spectrum response, is proposed. In the hierarchical game model of radar and jammer, the radar is in a leading position while the jammer is in a following position. The strategy of the jammer is optimized based on the radar transmitted waveform of previous moment, then the radar selects its own strategy based on the strategy of the jammer. It is generally assumed that the radar and the jammer have intercepted the real target spectrum and then the optimal jamming and the optimal transmitted waveform spectrum are obtained. However, the exact characteristic of the real target spectrum is hard to capture accurately in actual scenes. To simulate this, the real target spectrum is considered to be within an uncertainty range which is confined by known upper and lower bounds. Then, the minimax robust jamming and the maximin robust transmitted waveform are designed successively based on the MI criteria, which optimizes the performance under the most unfavorable condition of the radar and the jammer, respectively. Simulation results demonstrate that the robust transmitted waveform design method guarantees the parameter estimation performance effectively and provides useful guidance for waveform energy allocation.
Critical Distance of the Seismic Waves’ Impact in Disintegration of Rock Blasting
Authors: Kudelas Dušan , Pandula Blažej , Cehlár Michal , Taušová Marcela , Koščo Ján
Published: March 2019

The presented paper deals with attenuation of seismic waves, which depends on the degree of disintegration of the rock environment in which seismic waves are propagated due to the explosion of explosive charges during blasting operations. Measurements of the impact of seismic waves were conducted to determine the best possible way to absorb these waves. The aim of the article is to identify the existence of a critical distance and the determination of the critical point from which the propagation of the velocity is not dependent on the type of deposit and the environment in which the seismic wave propagates. Statistical methods were used for these findings. The result is the determination of the distance of 80 m in which the speed on the individual deposits varied. From this limit on, there was no significant difference in the speed of propagation on the individual deposits.
Surface Immobilization of TiO2 Nanotubes with Bone Morphogenetic Protein-2 Synergistically Enhances Initial Preosteoblast Adhesion and Osseointegration
Authors: Li Ying , Song Yunjia , Ma Aobo , Li Changyi
Published: March 2019

Although titanium (Ti) alloys have been widely used as implant materials, the bioinertness of pristine Ti impairs their bioactivity and early osseointegration. In the present work, we prepared TiO2 nanotubes (TNT) layer on the titanium (Ti) surface by anodic oxidation. The anodized surface was functionalized with human bone morphogenetic protein-2 coating to form the hBMP-2/TNT surface. The release behavior of hBMP-2 on the hBMP-2/TNT surface displayed a controlled and sustained pattern, compared to that on the hBMP-2/Ti surface, which showed a rapid release. In vitro cellular activity tests demonstrated that both TNT and hBMP-2/Ti surfaces, particularly the hBMP-2/TNT surface, enhanced adhesion, proliferation, and differentiation of osteoblast cells. Increased cell adhesion, improved cytoskeleton organization, and immunofluorescence staining of vinculin were observed on the modified surfaces. The TNT, hBMP-2/Ti, and hBMP-2/TNT surfaces, especially the hBMP-2/TNT surface, further displayed an upregulated gene expression of adhesion and osteogenic markers vinculin, collagen type 1, osteopontin, and osteocalcin, compared to the pristine Ti surface. In vivo experiments using a rat model demonstrated that the TNT and hBMP-2/Ti surfaces, in particular the hBMP-2/TNT surface, improved osseointegration and showed a superior bone bonding ability compared to Ti. Our study revealed a synergistic role played by TiO2 nanotubes nanotopography and hBMP-2 in promoting initial osteoblast adhesion, proliferation, differentiation, and osseointegration, thus suggesting a promising method for better modifying the implant surface.
Application of Spritz Encryption in Smart Meters to Protect Consumer Data

Published: March 2019

The ongoing upgrade of the electrical power system into a more powerful system known as Smart Grid has both benefits and costs. Smart Grid relies on advanced communication and hence offers better services through improved monitoring, planning, and control. However, enhanced communications make Smart Grid more susceptible to privacy leaks and cyber attacks. Small meters collect detailed consumer data, such as power consumption, which can then become a major source of privacy leakage. Encryption can help protect consumer data, but great care is needed. The popular RC4 (Rivest Cipher 4) encryption has been implemented in the widely deployed smart meter standard—Open Smart Grid Protocol (OSGP)—but has been shown to have major weaknesses. This paper proposes the use of Spritz encryption. Spritz is an RC4-like algorithm designed to repair weak design decisions in RC4 to improve security. A test on performing one encryption took only 0.85 milliseconds, showing that it is fast enough not to affect the operations of a smart meter. Its ability to withstand brute force attacks on small keys is also significantly greater than RC4’s ability.

Purpose. This study aimed to evaluate the statuses of P16INK4A expression and human papillomavirus (HPV) infection among patients with penile cancer at a single Korean institution. Patients and Methods. Fourteen patients with penile cancer at our center were retrospectively identified and their clinicopathological data were analyzed. The patients’ HPV and P16INK4A expression status (a known tumor suppressor protein) were tested using genotyping with a DNA chip assay and immunohistochemical staining, respectively. The results regarding HPV status were compared to those from another Asian study. Results. The mean age at diagnosis was 60 years (range: 34–86 years). The median tumor size was 3.0 cm (range: 0.6–4.7 cm). Ten tumors were located on the penile glans. Five patients tested positive for HPV DNA (5/14, 36%) and all cases involved HPV type 16 (5/5, 100%). Positive expression of P16INK4A was observed in 6 cases (6/14, 43%). Among the HPV positive cases, 80% of cases (4/5) were also positive for P16INK4A. The prevalence of HPV infection in our study (36%) was higher than in a previous Asian study (23%). Conclusions. This is the first study to evaluate the prevalence of HPV infection and P16INK4A expression among patients with penile cancer at a single Korean institution. The prevalence of HPV (36%) was slightly higher than the results from a previous Asian study. Additional multi-center studies are needed to better understand penile cancer in Korea and to identify biomarkers that can determine high-risk cases and predict their prognosis.

Authors: Hou Ziming , Yang Jun , Wang Hao , Liu Dongyuan , Zhang Hongbing
Published: March 2019

Objective. This study aimed to screen prognostic gene signature of glioblastoma (GBM) to construct prognostic model.Methods. Based on the GBM information in the Cancer Genome Atlas (TCGA, training set), prognostic genes (Set X) were screened by Cox regression. Then, the optimized prognostic gene signature (Set Y) was further screened by the Cox-Proportional Hazards (Cox-PH). Next, two prognostic models were constructed: model A was based on the Set Y; model B was based on part of the Set X. The samples were divided into low- and high-risk groups according to the median prognosis index (PI). GBM datasets in Gene Expression Ominous (GEO, GSE13041) and Chinese Glioma Genome Atlas (CGGA) were used as the testing datasets to confirm the prognostic models constructed based on TCGA.Results. We identified that the prognostic 14-gene signature was significantly associated with the overall survival (OS) in the TCGA. In model A, patients in high- and low-risk groups showed the significantly different OS (P = 7.47 × 10−9, area under curve (AUC) 0.995) and the prognostic ability were also confirmed in testing sets (P=0.0098 and 0.037). The model B in training set was significant but failed in testing sets.Conclusion. The prognostic model which was constructed based on the prognostic 14-gene signature presented a high predictive ability for GBM. The 14-gene signature may have clinical implications in the subclassification of GBM.

Published: March 2019

Reprogrammed glucose metabolism of enhanced aerobic glycolysis (or the Warburg effect) is known as a hallmark of cancer. The roles of long noncoding RNAs (lncRNA) in regulating cancer metabolism at the level of both glycolysis and gluconeogenesis are mostly unknown. We previously showed that lncRNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) acts as a proto-oncogene in hepatocellular carcinoma (HCC). Here, we investigated the role of MALAT1 in regulating cancer glucose metabolism. MALAT1 upregulated the expression of glycolytic genes and downregulated gluconeogenic enzymes by enhancing the translation of the metabolic transcription factor TCF7L2. MALAT1-enhanced TCF7L2 translation was mediated by upregulation of SRSF1 and activation of the mTORC1–4EBP1 axis. Pharmacological or genetic inhibition of mTOR and Raptor or expression of a hypophosphorylated mutant version of eIF4E-binding protein (4EBP1) resulted in decreased expression of TCF7L2. MALAT1 expression regulated TCF7L2 mRNA association with heavy polysomes, probably through the TCF7L2 5′-untranslated region (UTR), as determined by polysome fractionation and 5′UTR-reporter assays. Knockdown of TCF7L2 in MALAT1-overexpressing cells and HCC cell lines affected their metabolism and abolished their tumorigenic potential, suggesting that the effects of MALAT1 on glucose metabolism are essential for its oncogenic activity. Taken together, our findings suggest that MALAT1 contributes to HCC development and tumor progression by reprogramming tumor glucose metabolism.

Significance:

These findings show that lncRNA MALAT1 contributes to HCC development by regulating cancer glucose metabolism, enhancing glycolysis, and inhibiting gluconeogenesis via elevated translation of the transcription factor TCF7L2.

Dicer1 functions as a tumor suppressor in mouse models. In humans, somatic mutations are associated with many cancers in adults, and patients with DICER1 syndrome with DICER1 germline mutations are susceptible to childhood cancers. Dicer is phosphorylated by the ERK-MAP kinase pathway and because this pathway is activated in human cancers, we asked whether phosphorylated Dicer1 contributed to tumor development. In human endometrioid cancers, we discovered that phosphorylated DICER1 is significantly associated with invasive disease. To test a direct involvement of Dicer1 phosphorylation in tumor development, we studied mice with phosphomimetic alterations at the two conserved serines phosphorylated by ERK and discovered that a phosphomimetic Dicer1 drives tumor development and dissemination in two independent murine cancer models (KRas+/LA1 and p53+/−). Our findings demonstrate that phosphomimetic Dicer1 promotes tumor development and invasion.

Significance:

This work highlights the relevance of Dicer1 phosphorylation in mammalian tumor development and dissemination.

Published: March 2019

Background

The JROAD‐DPC (Japanese Registry of All Cardiac and Vascular Diseases Diagnosis Procedure Combination) is a nationwide claims database comprised of the Japanese
DPC
/Per Diem Payment System. This study aimed to investigate the relationship between prescription rates of guideline‐directed medications in each hospital and in‐hospital mortality among patients with acute myocardial infarction.

Methods and Results

A total of 61 838 Japanese patients from 741 hospitals with acute myocardial infarction between 2012 and 2013 were enrolled. The relationship between prescription rates of 4 guideline‐directed medications for acute myocardial infarction and in‐hospital mortality was analyzed. There were variations in the prescription ratio of β‐blockers on admission (median prescription rate 23% [interquartile range 11% to 38%]) and at discharge (51% [36% to 63%]), and of angiotensin converting enzyme/receptor blocker (60% [47% to 70%]). The highest prescription rate quartile of each medication was associated with a significantly lower mortality compared with the lowest prescription rate quartile (aspirin on admission, incidence rate ratio 0.67 [95%
CI
0.61‐0.74],
P
<0.001; aspirin at discharge, incidence rate ratio 0.50 [95%
CI
0.46‐0.55],
P
<0.001; β‐blocker on admission, 0.83 [0.76‐0.92],
P
<0.001; β‐blocker at discharge, 0.78 [0.71‐0.85],
P
<0.001; angiotensin converting enzyme/receptor blocker, 0.68 [0.62‐0.75],
P
<0.001; statin, 0.63 [0.57‐0.70],
P
<0.001). The composite prescription score was inversely associated with in‐hospital mortality (β coefficient=−0.48,
P
<0.001) and was closer to the plateau in the high‐score range (median mortality for composite prescription scores of 6, 15, and 24 were 10.6%, 6.8%, and 4.6%, respectively).

Conclusions

The prescription rates of guideline‐directed medications for treatment of Japanese acute myocardial infarction patients were inversely associated with in‐hospital mortality.

Authors: Kang Shuai , Liu Xingju , Zhang Dong , Wang Rong , Zhang Yan , Zhang Qian , Yang Wuyang , Zhao Ji-zong
Published: March 2019

Background and Purpose—

Evidence on the natural history of hemorrhagic moyamoya disease is still insufficient. We investigated the incidence of recurrent intracranial bleeding, mortality, and risk factors for rebleeding in patients with moyamoya disease.

Methods—

A total of 128 conservatively managed patients with hemorrhagic presentation and complete follow-up data were included. Recurrent hemorrhages during long-term follow-up were documented. Annual and cumulative incidence rate of bleeding was generated via Kaplan-Meier survival analysis, and risk factors were analyzed using logistic regression analysis.

Results—

The median follow-up time was 10.1 (1–27) years. During a total of 1300.7 patient-years, 47 (36.7%) patients experienced 59 occurrences of recurrent hemorrhages, rendering an average annual incidence of 4.5%. Among them, 9 patients (19.1%) died from rebleeding and 12 patients sustained severe disability (modified Rankin Scale score of ≥3). The cumulative risk of rebleeding was 7.8% at 5 years, 22.6% at 10 years, and 35.9% at 15 years. Only 4 (3.1%) patients experienced ischemic stroke, yielding an average annual incidence of 0.3%. Multivariate analysis showed that smoking (odds ratio, 4.85;
P
=0.04) was an independent risk factor of rebleeding. Rebleeding (hazard ratio, 11.04;
P
=0.02) and hypertension (hazard ratio, 4.16;
P
=0.04) were associated with increased mortality. Age, type of initial bleeding, digital subtraction angiography staging, family history, and coexisting cerebral aneurysms were not associated with increased risk of rebleeding.

Conclusions—

Rebleeding events were common and the main cause of death in patients with hemorrhagic moyamoya disease. The risk of rebleeding steadily increased during long-term follow-up. Smoking was a risk factor for rebleeding, and hypertension was associated with increased mortality.

Published: March 2019

Background and Purpose—

Early hematoma expansion after intracerebral hemorrhage is a potentially modifiable predictor of outcome and a promising therapeutic target. Radiological markers seen on noncontrast computed tomography can help predict hematoma expansion and risk stratify patients presenting with intracerebral hemorrhage. Our objective was to assess the interrater and intrarater reliability of 5 commonly reported noncontrast computed tomographic markers of hematoma expansion.

Methods—

Four readers independently reviewed images from 40 patients from 2 intracerebral hemorrhage imaging databases (PREDICT Collaboration [Predicting Haematoma Growth and Outcome in Intracerebral Haemorrhage Using Contrast Bolus CT] and Massachusetts General Hospital). Readers were blind to all demographic and outcome data and used accepted definitions to establish the presence or absence of intrahematoma hypodensities, blend sign, fluid level, irregular hematoma morphology, and heterogeneous hematoma density. We calculated interrater and intrarater agreement and stratified kappas for the 5 imaging markers.

Results—

Interrater agreement was excellent for all 5 markers, ranging from 94% to 98%. Interrater kappas ranged from 0.67 to 0.91 (the lowest for fluid level). Interrater agreement had a similar pattern, ranging from 89% to 93%, with Kappas ranging from 0.60 to 0.89.

Conclusions—

We show that 5 commonly used noncontrast computed tomographic imaging findings all have good-to-excellent interrater and intrarater reliabilities, with the best kappa for blend sign, hypodensities, and heterogeneity.

Muscular characters in the phylogeny of Liolaemus (Squamata: Iguania: Liolaemidae): a reappraisal
Authors: ABDALA V. , ABDALA C. , TULLI M. J.
Published: March 2019

Liolaemus is one of the most speciosus genera of lizards, having more than 200 species. It is composed of small to moderate-sized lizards that live throughout most of austral South America. Many groups whose phylogenetic relationships have been controversial compose the genus. The proposed phylogenetic relationships of these lizards have been based on data-sets from many sources. In all of the morphological data-sets, three myologycal characters have been considered particularly important:1) insertion of the m. tibialis anticus hypertrophied in association with the presence of a sharp, bladelike process of the tibia, 2) medial head of the m. flexor tibialis internus covered by a hypertrophied m. puboisquitibialis, and 3) presence of melanic pigment within the medial portion of the epimysium of the m. pterygomandibularis. Important taxonomic and anatomical questions about these characters remain: 1) Can the size of the m. puboisquiotibilis be scored with only two character states? 2) Is there a close relationship between the hypertrophied m. flexor tibialis internus and the patch of the enlarged proximal postfemoral scales? and 3) Are these muscular characters exclusive to some of the groups of Liolaemus that have been proposed? Focusing on these questions, we have conducted a taxonomic and anatomic review of these characters in 42 species representing all of the proposed groups of Liolaemus. The analyzed samples show that variations in the considered muscular characters are much more gradual than previously stated. The only exception is the insertion of the m. tibialis anticus hypertrophied in relation to a bladelike hypertrophy of the tibia, which characterizes the montanus group of E theridge (1995). These characters seem to have the same phylogenetic information as any other morphological character. Although the coding we used is more complex, it shows more precisely the subtlety of the change in the character states.

The bogidiellid amphipod crustaceans Stockigi diella aequim ana new genus and species and Om angidiella p arvid actyl a new genus and species are described from subterranean groundwater habitats in the Sultanate of Oman on the Arabian Peninsula. Stockigidiell a is easily distinguished by a row of long, deeply bifid setae on pereopods 5 and 6, whereas Omangidiell a is distinguished by a greatly reduced propodus of gnathopod 2 and elongate oostegites; it also possesses a third coxal lobe on the maxilliped, a unique character noted only in three other bogidiellid genera from northern and eastern Africa. At present, the family Bogidiellidae contains 35 genera and 105 species but a significant number of provisionally recognized new species and possibly several new genera await description. The geographic distribution of the family Bogidiellidae is nearly circumglobal, but species tend to be clustered in discontinuous regions. A number of important questions regarding the origin and biogeographic history of the family remains unanswered.

Analysis of the female-based genera of the tiphiid wasp subfamily Brachycistidinae revealed the need to remove Astigmometopa Mickel & Krombein from synonymy with Brachycistis and synonymize it under Glyptacros Mickel & Krombein, synonymize the genus Quemaya Pate under Stilbopogon Mickel & Krombein, synonymize Bruesiella Mann and Aulacros Mickel & Krombein under Brachycistis Fox, and synonymize Xeroglypta Mickel & Krombein under Glyptacros. , In addition, shared characteristics found only in Aglyptacros Mickel & Krombein and Colocistis Krombein demonstrate the need toand synonymize Aglyptacros under Colocistis. Females This is the first time that females have been identified for two genera, Colocistis and Stilbopogon. Previously, females were only known for Brachycistis.[neither of the previous two sentences make sense in light of the rest of the ms – the first suggests either that you are describing two femalebased genera and the second that there has, until now, only been one-please clarify this], Phylogenetic analysis of the generic groupings based upon 21 binary morphological characters resulted in two moderately supported clades, Aglyptacros Colocistis+ Brachycistis, Glyptacros, and Stilbopogon + Genus A (an unnamed, phylogenetically discrete group of females). New generic combinations involve moving all of the species of Quemaya into Stilbopogon; the placement of Bruesiella formicaria Mann, Glyptometopa americana Ashmead, Eurycros furtivus Mickel & Krombein and Aulacros latior Mickel & Krombein in Brachycistis; the assignment of Glyptometopa eureka Banks to Colocistis and Xeroglypta egregia Mickel & Krombein and Astigmometopa emarginata Mickel & Krombein to Glyptacros.
Szidatitrema yamagutii n. sp. (Digenea: Cyclocoelidae: Ophthalmophaginae) from the bearded barbet, Lybius dubius (Capitionidae), and the white-necked myna, Streptocitta albicollis (Sturnidae), that died at the Audubon Zoo in New Orleans, Louisiana, U.S.A.

Szidatitrema yamagutii n. sp. was found in the air sacs and body cavities of 2 bearded barbets, Lybius dubius, and a white-necked myna, Streptocitta albicollis, that died at the Audubon Zoo, New Orleans, Louisiana between June, 2000 and April, 2005. The new species can be distinguished from Szidatitrema philomachii and Szidatitrema vogeli, the only species currently assigned to this genus, by having a smaller egg size (80–105 by 40–55 compared to 117–126 by 54–72 and 110 by 50, respectively) and the testes of S. yamagutii n. sp. are less obliquely positioned relative to each other. Szidatitrema yamagutii n. sp. further differs from S. philomachii by lacking an oral sucker and having larger testes (anterior testis 405 by 375 compared to 270 by 210; posterior testis 435 by 370 compared to 225 by 210) and from S. vogeli by having a shorter cirrus sac (345 compared to 554) ), smaller testes (anterior testis 405 long compared to 700; posterior testis 435 long compared to 500), a smaller ovary (220–330 wide compared to 400), and a larger postovarian space (approximately 10% of body length compared to 6%). This new species was likely introduced into the Audubon Zoo through the importation of species of Old World birds.

Authors: STEINER JOSEFINA , HARTER-MARQUES BIRGIT , ZILLIKENS ANNE , FEJA EDUARDO P.
Published: March 2019

On Santa Catarina Island bees were collected between 1999 and 2006 using various methods, including netting, trap nesting, and baiting. Vegetation types sampled comprised secondary forests, dunes, pastures, and parks. A checklist of 166 species of bees is presented. The family Apidae was represented by the highest number of species, followed by Megachilidae and Halictidae. Only a few species of Colletidae and Andrenidae were recorded. Species richness and occurrence of genera are compared to the results of other collections performed in the neighboring states of Paraná and Rio Grande do Sul.

Published: March 2019

Larval development of the mud shrimp Upogebia issaeffi (Balss, 1913) (Decapoda: Gebiidea: Upogebiidae) is describedand illustrated for the first time from material reared in the laboratory. The development includes four zoeal and a singlemegalopal stages. At 20–22°C the first megalopa was attained 12 days after hatching. U. issaeffi is distinguished from U.major, the second upogebiid species inhabiting Russian waters of the Sea of Japan, by the presence of the fourth zoeal stage and considerably more intensive larval setation.

Authors: MARIN IVAN
Published: March 2019

The “Hamopontonia corallicola” Bruce, 1970 species complex is partly revised. The type species of the genus, H. corallicolaBruce, 1970, is redescribed based on material from Northern Australia. Additionally, two new species of the genus associatedwith hard corals are described from Lizard Island, the Great Barrier Reef, Australia. Hamopontonia fungicola sp. nov. isassociated with fungiid coral Heliofungia actiniformis (Quoy & Gaimard, 1833) and H. physogyra sp. nov. is associated withcaryophyllid coral Physogyra lichtensteini Milne-Edwards & Haime, 1851. Both species clearly differ from their congeners indistinctive coloration and morphological features. A differential key and remarks on coloration of all described species of the genus are provided.

Two new species of shallow-water hermit crabs (Crustacea: Decapoda: Paguridae) from Mayotte, Comoro Islands, southwestern Indian Ocean
Authors: KOMAI TOMOYUKI , POUPIN JOSEPH
Published: March 2019

Two new species of pagurid hermit crabs are described from shallow coral reefs of Mayotte, Comoro Islands, southwest-ern Indian Ocean. Cestopagurus caeruleus sp. nov., representing the fourth of the genus, is morphological similar to C.coutieri Bouvier, 1897 and C. timidus (Roux, 1830), but the new species is immediately distinguished from the latter twospecies by the proportionally longer antennular peduncles and the different armature of the dactylus of the right cheliped.Trichopagurus asper sp. nov., representing the third species of the genus, appears closer to T. macrochela Komai & Osa-wa, 2005, but the tuberculate dorsal surface of the right palm and the possession of spines on the carpus of the left cheliped readily differentiate the new species from the latter species.
On nomenclature and synonymy of Trichius rosaceus, T. gallicus, and T. zonatus (Coleoptera: Scarabaeidae: Cetoniinae: Trichiini)
Authors: KRELL FRANK-THORSTEN
Published: March 2019

The name Scarabaeus rosaceus Voet, 1766–1778, currently in use as one of two names for a west Palaearctic Trichius species, is unavailable because Voet’s work is not consistently binominal. The valid name for the species is Trichius gallicus Dejean, 1821 with the Sardinian and North African populations forming the subspecies T. g. zonatus Germar, 1831. The lectotype of Trichius zonatus Germar is designated.
Designation of a lectotype for Pseudoceros kylie Newman & Cannon, 1998 (Platyhelminthes, Polycladida, Pseudocerotidae)
Authors: HALL KATHRYN A. , ADLARD ROBERT D.
Published: March 2019

Recently, we have been examining the literature relevant to Australian “Turbellaria” (Phylum Platyhelminthes) and have noticed that there was an omission in the paper of Newman & Cannon (1998).  In this work, Newman & Cannon proposed several new species of Pseudoceros Lang, 1884.  There appears to have been an oversight in the typification of one species, Pseudoceros kylie Newman & Cannon, 1998, in that no types were officially designated.  Here we recommend new types, which we propose to designate as lectotype and paralectotypes, based on the material examined by Newman & Cannon in their description.  All of this material is deposited currently in the Queensland Museum, Australia.

Two new heterobathmiid moth species with distinctive female genital configurations (Lepidoptera: Heterobathmiidae)
Authors: HÜNEFELD FRANK , KRISTENSEN NIELS P.
Published: March 2019

Two new species of the basal (non-glossatan) moth family Heterobathmiidae are described: Heterobathmia megadecellaand H. nielsenella. Both species have particularly notable features in their female postabdomen: H. megadecella has adistinct sclerotization in the genital chamber and a somewhat elaborate sclerite complement on the otherwise membranousventer of the ‘terminal unit’ formed by segments IX–X(XI), and H. nielsenella has a remarkable forwards extension of thesclerotized upper surface of the ‘subgenital plate’ and a continuation of this extension into a sizable apodemal lamella.The description of these taxa in advance of a comprehensive taxonomic treatment of all presently available Heterobathmia(including a number of additional undescribed species) is prompted by the need for available names to be used in a morphological treatment of the heterobathmiid postabdomen now nearing completion.

The Lower Ordovician (upper Floian) bathyurid trilobite Aponileus Hu, with species from Utah, Texas, and Greenland
Authors: ADRAIN JONATHAN M. , McADAMS NEO E. B.
Published: March 2019

The previously monotypic bathyurid trilobite Aponileus Hu, 1963, was known only from poorly preserved material of itstype species, A. latus, and was interpreted as a junior subjective synonym of Psephosthenaspis Whittington. New speciesfrom the upper Floian (Blackhillsian) Fillmore Formation of western Utah belong to Aponileus and help demonstrate thatthe genus is an entirely Lower Ordovician (upper Floian) clade phylogenetically separate from the Middle Ordovician(Dapingian) Psephosthenaspis. Species of either group have broadly similar morphology, but the species of Psephosthe-naspis which most closely resembles those of Aponileus is the youngest and most derived member, and the similarities areconvergent. Psephosthenaspis roots among a group of heavily tuberculate, mostly undescribed, upper Floian species, oneof which is briefly illustrated for comparison. The species most resembling some species of Aponileus, P. glabrior, is il-lustrated on the basis of new silicified material which extends its range from the upper Juab Formation into the base of theKanosh Formation. New Blackhillsian species are A. laikaae (Fillmore Formation; Presbynileus ibexensis Zone), A. aasei(Fillmore Formation; probably Pseudocybele paranasuta Zone), A. belkaae, A. strelkaae, and A. ugolekae (all Wah WahFormation; "Pseudocybele nasuta Zone"). Aponileus? veterokae n. sp., from high in the "Pseudocybele nasuta Zone" ofthe Wah Wah Formation, is tentatively assigned. Bolbocephalus glaber Poulsen, 1927, from the Nunatami Formation ofnorthwest Greenland, is poorly known but is also a member of Aponileus, and is similar in morphology to A. latus and A.aasei; it is revised on the basis of reillustrated type material. Phylogenetic analysis indicates that A. laikaae is the basalspecies, followed by a sister pair of A. belkaae and A. strelkaae. These are sister to a pair of subclades, the sister pair of A. ugolekae and A.? veterokae, and an effaced group lacking genal spines including A. aasei, A. latus, and A. glaber.
