Paclitaxel-Coated Balloons and Eluting Stents: Is There a Mortality Risk in Patients With Peripheral Artery Disease?
Authors: Beckman Joshua A. , White Christopher J.
Published: June 2019

Paclitaxel drug-coated balloons and drug-eluting stents became commercially available for the treatment of intermittent claudication in 2015 and 2012, respectively. Both devices demonstrated superiority in limb revascularization compared with non–paclitaxel-coated devices and were rapidly accepted into clinical practice. In a recent systematic review and study-level meta-analysis, Katsanos et al reported a late all-cause mortality signal for patients in the drug-coated balloon and drug-eluting stent arms of randomized clinical trials for both devices. As a result of this safety signal, Vascular InterVentional Advances Physicians (VIVA), a not-for-profit 501c(3) organization, convened the Vascular Leaders Forum on March 1 and 2, 2019, in Washington, DC, to initiate an open and collaborative process of investigation into this finding. The Vascular Leaders Forum brought together 100 stakeholders, including an international group of representatives of cardiovascular medicine, interventional radiology, vascular medicine, and vascular surgery; oncologists; basic scientists; the Food and Drug Administration; the Centers for Medicare and Medicaid Services; and commercial manufacturers of these products. The Vascular Leaders Forum reviewed the natural history of peripheral arterial disease, the use of paclitaxel in peripheral arterial disease and other conditions, the harm signal noted by Katsanos et al, the impact of the methods chosen by Katsanos et al, possible mechanisms of harm, the role of the Food and Drug Administration in a setting like this one, and guidance for clinicians taking care of patients with symptomatic peripheral arterial disease. This document integrates the most current data to help establish an appropriate path forward to understand the risks and benefits associated with these technologies while ensuring the best treatment paradigm for patients.

Dyslipidemia is common in chronic kidney disease (CKD). Despite statins, many patients fail to adequately lower lipids and remain at increased risk of cardiovascular disease. Selective ET
A
(endothelin-A) receptor antagonists reduce cardiovascular disease risk factors. Preclinical data suggest that ET
A
antagonism has beneficial effects on circulating lipids. We assessed the effects of selective ET
A
antagonism on circulating lipids and PCSK9 (proprotein convertase subtilisin/kexin type 9) in CKD. This was a secondary analysis of a fully randomized, double-blind, 3-phase crossover study. Twenty-seven subjects with predialysis CKD on optimal cardio- and renoprotective treatment were randomly assigned to receive 6 weeks dosing with placebo, the selective ET
A
receptor antagonist, sitaxentan, or long-acting nifedipine. We measured circulating lipids and PCSK9 at baseline and then after 3 and 6 weeks. Baseline lipids and PCSK9 did not differ before each study phase. Whereas placebo and nifedipine had no effect on lipids, 6 weeks of ET
A
antagonism significantly reduced total (−11±1%) and low-density lipoprotein–associated (−20±3%) cholesterol, lipoprotein (a) (−16±2%) and triglycerides (−20±4%); high-density lipoprotein–associated cholesterol increased (+14±2%),
P
<0.05 versus baseline for all. Additionally, ET
A
receptor antagonism, but neither placebo nor nifedipine, reduced circulating PCSK9 (−19±2%;
P
<0.001 versus baseline;
P
<0.05 versus nifedipine and placebo). These effects were independent of statin use and changes in blood pressure or proteinuria. Selective ET
A
antagonism improves lipid profiles in optimally-managed patients with CKD, effects that may occur through a reduction in circulating PCSK9. ET
A
receptor antagonism offers a potentially novel strategy to reduce cardiovascular disease risk in CKD.

The mineralocorticoid aldosterone increases in plasma in healthy pregnancy along with renin and angiotensin II and plays a key role in the physiological plasma volume expansion. In mice, aldosterone contributes to an optimal fetal development by enhancing PlGF (placental growth factor) expression and trophoblast cell proliferation. In preeclampsia, there is coincident suppression of aldosterone and impaired placental development. We hypothesized that aldosterone independently contributes to placental and birth weight in humans, and high dietary sodium and low potassium intakes affect this relationship adversely. We analyzed 24-hour urine collections and plasma samples from gestational week 29 in a subsample of 569 pregnant women from the Odense Child Cohort—a Danish population-based longitudinal cohort study. Plasma and urinary aldosterone were measured by ELISA, sodium and potassium excretions by flame photometer. Predictive values of aldosterone levels and sodium and potassium intakes were assessed by multiple and Cox regression analyses. Primary outcomes were placental weight and birth weight. Secondary outcome was preeclampsia. Urinary aldosterone excretion at gestational week 29 independently contributed to placental and birth weights (adjusted β-coefficients [95% CI], 24.50 [9.66–39.35] and 9.59 [4.57–14.61], respectively). Aldosterone levels were not associated to preeclampsia incidence. Salt intake >6 g/d was associated with development of preeclampsia (hazard ratio [95% CI], 5.68 [1.51–21.36]). At gestational week 29, urinary aldosterone excretion is an independent predictor of placental and birth weights. High salt intake is a risk factor for preeclampsia. In perspective, suppression of aldosterone in pregnancy has adverse trophic effects.

Published: June 2019

Background and Purpose—

Do-not-resuscitate (DNR) orders are common after stroke, though there are limited data on trends over time. We investigated time trends in DNR orders in a community with a large minority population.

Methods—

Cases of ischemic stroke (IS) or intracerebral hemorrhage (ICH) were identified from the BASIC study (Brain Attack Surveillance in Corpus Christi) from June 2007 through October 2016. Cox proportional hazards models were used to assess time to DNR orders, with an interaction term added to allow separate hazard ratios for early (≤24 hours) and late (>24 hours) DNR. Stroke type–specific calendar trends were assessed with an interaction term between calendar year (linear) and stroke type.

Results—

Two thousand six hundred seventy-two cases were included (ICH, 14%). Mean age was 69, 50% were female, and race-ethnicity was Mexican American (58%), non-Hispanic white (37%), and African American (5%). Overall, 16% had a DNR order during the hospitalization. For ICH, DNR orders (early and late) were stable over the study period. However, early DNR orders became more common over time after ischemic stroke (hazard ratio for 2016 versus 2007: 1.89; 95% CI, 1.06–3.39), with no change over time for late DNR orders after ischemic stroke. Mexican Americans (hazard ratio, 0.65; 95% CI, 0.50–0.86) and African Americans (hazard ratio, 0.17; 95% CI, 0.04–0.71) were less likely than non-Hispanic whites to have early DNR orders, though there were no race-ethnic differences in late DNR orders. There was no change in race-ethnic difference in DNR orders over the time of the study (interaction
P
>0.60).

Conclusions—

Despite revised national guidelines cautioning against early DNR orders in ICH, presence of DNR orders after ICH was stable between 2007 and 2016, with only slight increases in early DNR orders after ischemic stroke. Mexican Americans and African Americans remain less likely than non-Hispanic whites to have early DNR orders after stroke.
Short-Term Double Layer Mesh Stent Patency for Emergent or Elective Carotid Artery Stenting
Authors: de Vries Evelien E. , Vonken Evert J. , Kappelle L. Jaap , Toorop Raechel J. , de Borst Gert J.
Published: June 2019

Background and Purpose—

Novel double layer micromesh stents have recently been introduced for treatment of patients with significant carotid stenosis. Strict evaluation of safety and patency of such novel devices is required both in elective and in emergency interventions. We report a single center experience with double layer mesh stents for carotid artery revascularization.

Methods—

Consecutive patients who underwent carotid artery stenting with a double layer mesh stent between June 2015 and September 2018 in our tertiary vascular referral center were included. Treatment indications were emergent carotid artery stenting for intracranial or extracranial carotid stenosis in patients undergoing intraarterial thrombectomy for acute ischemic stroke in the anterior circulation, or elective carotid artery stenting for significant symptomatic or asymptomatic stenosis. End points were postprocedural thrombotic stent occlusion and procedural stroke or death.

Results—

Fifty-four patients were included; 27 were treated for acute stroke with intracranial and extracranial (tandem) lesions and 27 for elective stenting. Follow-up imaging was available for 9/27 (33%) patients with acute stroke, and 19/27 (70%) electively treated patients. Five stent occlusions occurred, of which 2 were symptomatic with clinical deterioration within one day. Another patient deteriorated on postprocedural day one, but imaging of the carotids was not performed, and the stent turned out occluded on the 30-day duplex. All stent occlusions occurred in patients treated for acute stroke.

Conclusions—

This study suggests that occlusion of novel double layer mesh stents occurs in a considerable proportion of carotid artery stenting procedures performed in the emergency setting for acute stroke, with occlusion-related symptoms in half the cases. Future prospective studies should clarify the role of double layer mesh stents in this high-risk patient population.

Published: June 2019

Background and Purpose—

Substantial proportion of patients who achieve successful recanalization of acute ischemic stroke due to large vessel occlusion do not achieve good functional outcome. We aim to analyze the effect of number of thrombectomy device passes and degree of the recanalization (by modified Thrombolysis in Cerebral Infarction) on the clinical and functional outcome.

Methods—

Five hundred forty-two consecutive patients underwent mechanical thrombectomy for large vessel occlusion in the anterior circulation at a single tertiary stroke center. Baseline characteristics, number of passes, recanalization degree, clinical outcome at 24 hours (measured by National Institutes of Health Scale score), and functional outcome (measured by modified Rankin Scale at 90 days) were registered. Multivariate analysis was performed to determine the association of number of passes and degree of recanalization with dramatical clinical recovery (final National Institutes of Health Scale score ≤2 or decrease in 8 or more National Institutes of Health Scale score points in 24 hours) and good functional outcome (modified Rankin Scale score ≤2 at 90 days).

Results—

Four hundred fifty-nine patients (84%) achieved successful recanalization (modified Thrombolysis in Cerebral Infarction 2B–3), 213 (39%) of them after first device pass. In the multivariate analysis, first-pass recanalization and modified Thrombolysis in Cerebral Infarction 3 were independent predictors of good functional outcome (odds ratio, 2.5; 95% CI, 1.4–4.5;
P
=0.002 and odds ratio, 2.6 CI; 1.5–4.7;
P
=0.001, respectively) and dramatical clinical recovery (odds ratio, 1.8; 95% CI, 1.1–3;
P
=0.032 and odds ratio, 2.9; 95% CI, 1.7–5.1;
P
<0.001, respectively). Rate of recanalization declined after each pass 39% (213/542), 35% (113/310), 33% (63/190), and 24% (26/154) for passes 1 to 4, respectively and 28% (45/158) for every attempt above 4 passes (
P
<0.001). In patients who achieved recanalization, a linear association between number of passes and good functional outcome was observed: 1 pass (58.6%), 2 passes (50.5%), 3 passes (48.4%), 4 passes (38.5%), or 5 or more passes (25.6%;
P
<0.001) as compared with patients who did not achieve recanalization (16.9%).

Conclusions—

High number of device passes and less degree of recanalization are associated with worse outcome in patients with acute ischemic stroke secondary to large vessel occlusion. Future studies should investigate the optimal number of passes that should be attempted in patients without substantial recanalization.
Complement Inhibition Attenuates Early Erythrolysis in the Hematoma and Brain Injury in Aged Rats
Authors: Wang Ming , Hua Ya , Keep Richard F. , Wan Shu , Novakovic Nemanja , Xi Guohua
Published: June 2019

Background and Purpose—

Early erythrolysis in the hematoma contributes to brain injury after intracerebral hemorrhage (ICH). This study investigated the effects of N-acetylheparin, a complement inhibitor, and aurin tricarboxylic acid, a membrane attack complex inhibitor, on early erythrolysis, brain iron deposition, and brain injury in aged rats.

Methods—

There were 3 parts in the study. First, aged (18 months old) male Fischer 344 rats had an ICH. The time course of erythrolysis in the hematoma was determined by T2* weighted magnetic resonance imaging, and the expression of CD163 was examined. Second, aged rats had an ICH with N-acetylheparin or vehicle. Rats were euthanized at days 1, 3, and 28 after magnetic resonance imaging (T2-, T2*-weighted, and T2* array) and behavioral tests. Brains were used for immunohistochemistry. Third, aged rats had an ICH with avaurin tricarboxylic acid or vehicle. The rats had magnetic resonance imaging and behavioral tests and were euthanized at day 3. Brains were used for immunohistochemistry.

Results—

Early erythrolysis occurred within the clot in aged F344 rats. There were increased numbers of CD163-positive cells after ICH. Almost all perihematomal CD163-positive cells were microglia/macrophages, while positive neurons were found more distant from the hematoma. Coinjection of N-acetylheparin attenuated erythrolysis, iron accumulation, CD163 expression, microglia activation, brain swelling, and neuronal death in the acute phase, as well as reducing brain atrophy and neurological deficits in the chronic phase. Coinjection of aurin tricarboxylic acid also reduced erythrolysis and ICH-induced brain injury.

Conclusions—

Inhibiting complement activation resulted in less erythrolysis and brain injury after ICH.
Electrocardiomatrix Facilitates Accurate Detection of Atrial Fibrillation in Stroke Patients
Authors: Brown Devin L. , Xu Gang , Belinky Krzyske Alexandra Mary , Buhay Nicholas C. , Blaha Madeline , Wang Michael M. , Farrehi Peter , Borjigin Jimo
Published: June 2019

Background and Purpose—

Cardiac telemetry is a routine part of inpatient ischemic stroke/transient ischemic attack evaluation to assess for atrial fibrillation (AF). Yet, tools to assist stroke clinicians in the evaluation of the large quantities of telemetry data are limited. The investigators developed a new method to evaluate electrocardiographic signals, electrocardiomatrix, that was applied to stroke unit telemetry data to determine its feasibility, validity, and usefulness. Electrocardiomatrix displays telemetry data in a 3-dimensional matrix that allows for more accurate and less time consuming P-wave analysis.

Methods—

In this single-center, prospective, observational study conducted in a stroke unit, all telemetry data from ischemic stroke and transient ischemic attack patients were collected (April 2017–January 2018) for examination facilitated by electrocardiomatrix. AF>30 seconds was identified through review of electrocardiomatrix-generated matrices by a nonphysician researcher. Electrocardiomatrix results were compared with the clinical team’s medical record documentation of AF identified through telemetry. A study cardiologist reviewed the standard telemetry associated with all AF episodes identified by electrocardiomatrix and each case of disagreement.

Results—

Telemetry data (median 46 hours [interquartile range: 22–90]) were analyzed among 265 unique subjects (88% ischemic stroke). Electrocardiomatrix was successfully applied in 260 (98%) of cases. The positive predictive value of electrocardiomatrix compared with the clinical documentation was 86% overall and 100% among the subset with no prior history of AF. For the 5 false-positive and 5 false-negative cases, expert overview disagreed with the clinical documentation and confirmed the electrocardiomatrix-based diagnosis.

Conclusions—

The application of electrocardiomatrix to stroke unit-acquired telemetry data is feasible and appears to have superior accuracy compared with traditional monitor analysis by noncardiologists.
Anticipatory Distractor Suppression Elicited by Statistical Regularities in Visual Search
Authors: Wang Benchi , van Driel Joram , Ort Eduard , Theeuwes Jan
Published: June 2019

Salient yet irrelevant objects often capture our attention and interfere with our daily tasks. Distraction by salient objects can be reduced by suppressing the location where they are likely to appear. The question we addressed here was whether suppression of frequent distractor locations is already implemented beforehand, in anticipation of the stimulus. Using EEG, we recorded cortical activity of human participants searching for a target while ignoring a salient distractor. The distractor was presented more often at one location than at any other location. We found reduced capture for distractors at frequent locations, indicating that participants learned to avoid distraction. Critically, we found evidence for “proactive suppression” as already “prior to display onset,” there was enhanced power in parieto-occipital alpha oscillations contralateral to the frequent distractor location—a signal known to occur in anticipation of irrelevant information. Locked to display onset, ERP analysis showed a distractor suppression-related distractor positivity (PD) component for this location. Importantly, this PD was found regardless of whether distracting information was presented at the frequent location. In addition, there was an early PD component representing an early attentional index of the frequent distractor location. Our results show anticipatory (proactive) suppression of frequent distractor locations in visual search already starting prior to display onset.

New and little known species of Erasmoneura Young (Hemiptera: Cicadellidae: Typhlocybinae)
Authors: DMITRIEV D. A.
Published: June 2019

The North American leafhopper genus Erasmoneura Young was described as a subgenus of Erythroneura Fitch by Young (1952) to comprise the informal Erythroneura vulnerata Fitch species group previously recognized by Beamer (1938, 1946). Erasmoneura was recently elevated to generic status (Dietrich & Dmitriev, 2006) and revised (Dmitriev & Dietrich, 2007). In this paper, the male of Erasmoneura bipentagona (Beamer), previously known only from the female holotype and placed in the genus based on external similarity and features of wing venation (Young, 1952; Dietrich & Dmitriev, 2006; Dmitriev & Dietrich, 2007, see also the note for the species below), and a new species are described. A key for identification of all 13 species of the genus is provided. The key is based mainly on male genitalia characters. Although individual species have a characteristic color pattern, details and intensity may be highly variable both inter- and intraspecifically.

Published: June 2019

The exact number of extant delphinid species from seas around India is still debated and the lack of adequate field keys and reliable inventory has resulted in misidentification of several species. As a part of a project to develop a molecular taxonomy of cetaceans from this region, partial sequences of mtDNA cytochrome b were generated from accidentally caught/stranded delphinids and finless porpoise. Species were identified by phylogenetic reconstruction of sample sequences with the reference sequences available in portals GenBank (NCBI) and the web-based program DNA Surveillance. A comparison was made with the homologous sequences of corresponding species from other seas of the world. Our molecular investigations allowed us to identify five species of cetaceans from Indian coasts, including Delphinus capensis, previously reported as D. delphis. We detected unique haplotypes in Indo pacific humpbacked dolphin (Sousa chinensis; n = 2) and finless porpoise (Neophocaena phocaenoides; n = 12) from Indian coast. On the other hand, some haplotypes were shared with other regional populations in spinner dolphin (Stenella longirostris; n = 16) and bottlenose dolphin (Tursiops aduncus; n = 3). Common dolphins (Delphinus capensis; n = 2) had both unique and shared haplotypes including one highly divergent sequence.
The acasta conundrum: Polymorphism and taxonomic confusion within the parasitoid genus Melittobia (Hymenoptera: Eulophidae)
Authors: MATTHEWS ROBERT W. , GONZÁLEZ JORGE M.
Published: June 2019

Seven of the 13 described species of this gregarious, polyphagous, polymorphic parasitoid have been placed in the acasta species group of Melittobia Westwood (Hymenoptera: Eulophidae: Tetrastichinae) based on ethological and morphological criteria, but taxonomic confusion remains. Based on field and laboratory studies of variability and polymorphism, current species descriptors for this group are called into question and Melittobia femorata Dahms is synonymized under M. megachilis (Packard). Biologically, M. megachilis distinctly differs from other acasta group species in several aspects of life cycle and host utilization. Although M. acasta (Walker) and M. digitata Dahms are clearly valid species, three others (M. chalybii Ashmead, M. scapata Dahms, M. evansi Dahms) are more enigmatic and may be temporal, nutritional, or host-based variants of M. megachilis that will require additional study. The “Virginia” type locality for M. chalybii of authors is properly Bladensburg, Maryland, USA. One of the 13 female syntypes of Chrysocharis aeneus Brues (previously synonymized under M. megachilis) is designated as Lectotype.

The life cycle of Eucheilota medusifera ? (Torrey, 1902), comb. nov. [=Campalecium medusiferum] (Cnidaria: Hydrozoa: Lovenellidae) from the Bay of Biscay (northeastern Atlantic), including a description of the adult medusa
Authors: ALTUNA ÁLVARO
Published: June 2019

The life cycle of Campalecium medusiferum ? Torrey, 1902 (Cnidaria: Hydrozoa) was traced in the laboratory from material collected from the Bay of Biscay (northeastern Atlantic). Both newly released and one-month-old male medusae with fully-grown gonads are described, with remarks on their biology and behaviour. The adult medusa corresponds with the diagnosis of Eucheilota McCrady, 1859, and the species is reassigned from Haleciidae Hincks, 1868 to Lovenellidae Russell, 1953. The genus Campalecium Torrey, 1902 can be considered valid only if the characters of a species with Halecium-like polyps and Eucheilota-like medusae are considered of generic significance. Instead, the species studied here is assigned to Eucheilota, as E. medusifera ? (Torrey, 1902) (comb. nov.), and Campalecium is considered a likely synonym of that genus. The medusa is different from Lovenella cirrata (Haeckel, 1879), type species of the genus Mitrocomium Haeckel, 1879, previously suggested to have been linked to the same hydroid in the Mediterranean. A supposed connection between medusae of L. cirrata and Halecium-like hydroids cannot be supported, and assigning these hydroids to Mitrocomium is rejected. Future studies may prove that Halecium-like hydroids release medusae of diverse genera within the family Lovenellidae.
A new species of Crenicichla (Perciformes: Cichlidae) from the Ventuari River, Upper Orinoco River Basin, Amazonas State, Venezuela

Published: June 2019

We describe a new species of the genus Crenicichla Heckel, 1840, from the Ventuari River, a tributary of the Orinoco River in southern Venezuela. Crenicichla zebrina is distinguished from all other species in the genus by its unique coloration pattern, including the combination of a large, dark, vertically oriented, more or less oval-shaped humeral spot, and thin, dark bars, separated by narrow, vertical, yellowish bars extending between the dorsal and anal fin base on the caudal half of the body. Crenicichla zebrina is included in the putative C. acutirostris group (9 species) and represents the only species in the group known to date from the Orinoco basin.

Eulobomyia, a new replacement name for Lobomyia Woodley & Arnaud (Diptera: Tachinidae)
Authors: WOODLEY NORMAN E. , ARNAUD, JR. PAUL H.
Published: June 2019

A new genus, Lobomyia Woodley & Arnaud (Diptera: Tachinidae), from the Neotropical Region was recently described by us (Woodley & Arnaud, 2008: 32; type species, Lobomyia neotropica Woodley & Arnaud; published 6 June 2008).  At the time the manuscript was being prepared, one of us (NEW) checked available nomenclatural resources to ensure the generic name had not been previously used.  However, in the interim, the name Lobomyia was published as a new genus of Diptera, Chironomidae from Japan (Niitsuma, 2007: 105; type species, Lobomyia immaculata Niitsuma; published 15 June 2007).  We therefore propose a new replacement name here, Eulobomyia, nom. nov. for Lobomyia Woodley & Arnaud.  The gender of the name is feminine.

The tadpole of the bamboobreeding poison frog Ranitomeya biolat (Anura: Dendrobatidae)
Authors: VON MAY RUDOLF , MEDINA–MÜLLER MARGARITA , DONNELLY MAUREEN A. , Summers Kyle
Published: June 2019

Ranitomeya biolat occurs in the lowland rainforest of southern Peru and northwestern Bolivia and uses bamboo internodes as a retreat and reproduction site (Morales 1992; Maldonado & Reichle 2007). Unlike other members of the vanzolinii group, which exhibit biparental care of tadpoles (Summers & McKeon 2004), we have observed that R. biolat exhibits male–only parental care and that tadpoles are transported individually and deposited in water–filled bamboo internodes (Medina–Müller 2006; R. von May, unpublished data). After more than 12 months of sampling, we never observed individuals providing trophic eggs to tadpoles or observed oophagy as clutches were laid 3.5 ± 1.5 cm above the water (n = 55); hence, tadpole oophagy may not be an important food resource as previously suspected (Waldram 2008). Though basic information on its breeding biology has been published (Waldram 2008), its tadpole remains undescribed. With the purpose of filling this gap, we here describe the tadpole of R. biolat.

Authors: SIQUEIRA SÉRGIO , AGUIAR JR. ODAIR , STRÜSSMANN CHRISTINE , DEL-GRANDE MARIA LÚCIA , RECCO-PIMENTEL SHIRLEI MARIA
Published: June 2019

The karyotypes of four Brazilian “eleutherodactyline” samples were analyzed aiming to provide additional cytogenetic data for future understanding of the evolutionary and systematic relationships of this large anuran group. The populations consisted of Pristimantis dundeei (Chapada dos Guimarães and Rondonópolis, Mato Grosso), Pristimantis aff. dundeei (Aripuanã, Mato Grosso) and Ischnocnema paulodutrai (Ilhéus, Bahia). The data revealed that P. dundeei and P. aff. dundeei have 2n=28 chromosomes, whereas I. paulodutrai has 2n=30. All pairs of chromosomes were telocentric, except for the subtelocentric pair 4 in I. paulodutrai. Differences in Ag-NOR pattern and interstitial heterochromatin positions clearly distinguished P. aff. dundeei from P. dundeei, and differentiated them from I. paulodutrai. The specimens of I. paulodutrai showed two distinct color patterns, but they did not differ in their cytogenetic characteristics. Karyotypes with 2n=28 and 2n=30 chromosomes have not been previously described for Brazilian “eleutherodactylines” which, to date, had been characterized as 2n=20, 2n=22 and 2n=34. The NOR position differences identified between P. dundeei and P. aff. dundeei, allied to their known distinct behavior and ecological data, suggested that the P. aff. dundeei from the Aripuanã sampling location is a new species. Similarities between I. paulodutrai and species currently assigned to Pristimantis are herein discussed on the basis of chromosome number and morphological characteristics.
Two new spider species of the genera Aysenia and Aysenoides from southern Chile and Argentina: description and phylogenetic relationships (Araneae: Anyphaenidae, Amaurobioidinae)
Authors: IZQUIERDO MATÍAS A. , RAMÍREZ MARTÍN J.
Published: June 2019

Two new spider species of the genera Aysenia Tullgren and Aysenoides Ramírez (Anyphaenidae) from Malleco province, southern Chile, are described and their phylogenetic relationships discussed. The phylogenetic analysis confirmed the monophyly of Aysenia and Aysenoides. Support values for both genera are relatively high, compared with other members of the tribe Amaurobioidini, but support values for some internal branches are low. The genus Aysenia is supported by two synapomorphies corresponding to the shape of the dorsal shield of prosoma and absence of a group of spines on the tibia III, while Aysenoides is supported by four synapomorphies from gentialia and posterior eye proportions. The length of the male embolus and of the female copulatory duct seem to be functionally correlated in Aysenia.

Authors: TURNI HENDRIK , KOCK DIETER
Published: June 2019

The present catalogue documents all the chiropteran type specimens found in the collections of the Zoological Museum of the Humboldt-University, Museum für Naturkunde, Berlin (ZMB). Due to insufficient labeling at the time of receipt and description, many types have until now remained unrecognized, labelled with synonymous or incorrect names. From more than 13,000 specimens examined, we identified 540 types (86 holotypes, 249 syntypes, 22 lectotypes, 168 paratypes or paralectotypes, 5 of ambiguous status, 10 missing). These types belong to 218 described bat species, of which 116 are currently accepted (valid) species names. Lectotypes were designated for the original descriptions of Chilonycteris Boothi, Chiroderma villosum, Molossus ferox, Phyllorhina bicornis, Phyllostomus spiculatus, Rhinolophus capensis, Vespertilio Bocagii, Vespertilio Schreibersii and Vesperus cubanus.

A new species of Augustinus Korotyaev from China, with a key to the species groups of the genus (Coleoptera: Curculionidae: Ceutorhynchinae)
Authors: HUANG JUNHAO , YOSHITAKE HIRAKU , ZHANG RUNZHI , ITO MOTOMI
Published: June 2019

Augustinus tuberculatus Huang, Yoshitake & Zhang, sp. n., is described from Guizhou Province, southwestern China. The species is readily distinguishable from its congeners by the prothorax having five pairs of tubercles in addition to paired median prominences. We classify the species into a new species group, the A. tuberculatus group, based mainly on the basally convex rostrum, elytral interval 1 with a velvety black scaly patch in the basal 1/3, interval 3 with a large obtuse tubercle in the middle (with 1–3 rows of setiferous granules), the posterior margin of ventrite 2 angularly produced in the middle and the anterior and posterior margins of ventrite 4 equidistant along their entire length. A key to the species groups of Augustinus is provided.
Notes on the genus Afropachyiulus Schubart, 1960 (Diplopoda: Julida: Julidae) with a description of a new species from Algeria and a redescription of A. comatus (Attems, 1899)
Authors: AKKARI NESRINE , ENGHOFF HENRIK
Published: June 2019

The North African genus Afropachyiulus Schubart, 1960 is a poorly defined genus of the tribe Pachyiulini, the taxonomy of which is still obscure. In this paper we retrace the history of the genus Afropachyiulus, we describe A. mauriesi n. sp., from Algeria, and we redescribe the very similar A. comatus (Attems, 1899) from Tunisia based on type and new material.
Two new spider species, Malthonica bozhkovi sp. nov. and Tegenaria paragamiani sp. nov. from Rhodopy Mountains (Bulgaria and Greece) (Araneae: Agelenidae)
Authors: DELTSHEV CHRISTO
Published: June 2019

Malthonica bozhkovi sp. nov. (male/female) is described and illustrated from several localities in Rhodopy Mountains (South Bulgaria). The new species correspond well to the campestris species group. Tegenaria paragamiani sp. nov. (male/female) is described and illustrated from a cave in Rhodopy Mountain (North Greece). In morphological respect it fits well to the domestica species group. Malthonica ramblae (Barrientos, 1978) comb. nov. is transferred from the genus Tegenaria.
A re-description of the eastern Pacific swellshark, Cephaloscyllium ventriosum (Garman 1880) (Chondrichthyes: Carcharhiniformes: Scyliorhinidae), with comments on the status of C. uter (Jordan & Gilbert 1896)
Authors: SILVA JAYNA A. SCHAAF-DA , EBERT DAVID A.
Published: June 2019

The genus Cephaloscyllium Gill 1862 (Chondrichthyes, Carcharhiniformes, Scyliorhinidae), arguably has one representative species in the eastern Pacific, C. ventriosum (Garman 1880). While the C. ventriosum holotype was collected from central Chile, a dubious species, C. uter, (Jordan & Gilbert 1896) was described from California. Garman (1913) classified C. uter as a junior synonym of C. ventriosum. This study marks the first morphometric and meristic analysis comparing the holotype of C. ventriosum from Chile with California Cephaloscyllium specimens and presents a revision of the genus for the eastern Pacific. Based on a comparison of morphometric and meristic data from specimens collected from Monterey, California; Santa Catalina Island, California; Santa Barbara, California; Guadalupe Island, Mexico; and Valparaiso, Chile, it is concluded that the California and Chilean Cephaloscyllium species represent a single, wide-ranging species, C. ventriosum.

Authors: TENNENT W JOHN
Published: June 2019

Since BCS Warren’s seminal Monograph of the circumpolar satyrine butterfly genus Erebia Dalman, 1816, was published in 1936, more than 320 new names and some 200 papers dealing wholly or in large part with the genus have been published. A modern checklist of more than 1,300 names proposed for butterflies of the genus Erebia (sensu stricto), all of which have been checked at source, is presented together with the source publication and type locality (TL). Also presented is a bibliography of 1,200 published items concerning the genus. The checklist covers the period 1758–2006; such names proposed and papers published as have been noted after the 31st of December 2006 are also included.
