It is generally believed that there is correlation between cancer prognosis and pretreatment PLR and NLR. However, there are limited data about their role in diffuse large B cell lymphoma (DLBCL). This study aims to determine the prognostic value of pretreatment PLR and NLR for patients who have DLBCL. The associations between clinical characteristics and NLR and PLR were evaluated among 182 DLBCL patients from January 2005 to June 2016. The optimal cutoff values for high PLR (⩾150) and NLR (⩾2.32) in prognosis prediction were determined. The effect of NLR and PLR on survival was evaluated through multivariate Cox regression analysis, univariate analysis, and log-rank test. According to the evaluation results, patients with high NLR and PLR had significantly shorter OS (P=0.026 and P=0.035) and PFS (P=0.024 and P=0.022) compared with those who have low PLR and NLR. On multivariate analyses, IPI>2, elevated LDH, and PLR⩾2.32 were prognostic factors for OS and PFS in DLBCL patients. Therefore, we demonstrated that high PLR and NLR predicted adverse prognostic factors in DLBCL patients.

Purpose: The present study explored the effectiveness of the Lidcombe Program, the parent-child interaction therapy (PCIT) approach, and an integrated (Lid-PCIT) program on the treatment of children who stutter. Methods: The present research was a single-subject study with an alternative treatment design. Participants were 6 preschool children who were randomly assigned into three groups. Each group received the entire indirect (PCIT), direct (Lidcombe), or integrated (Lid-PCIT) program and were assessed through severity rating (SR), and percent stuttered syllables (%SS), and video analysis. Results: For all children the SR and the %SS were reduced but the percentage of non-overlapping data of the three interventions showed that it was reduced more in the Lidcombe and in the Lid-PCIT programs. Conclusions: This study provided preliminary evidence that Lidcombe, PCIT, and integrated programs were effective in reducing the SR and the %SS in preschool children who stutter. These results are potentially important as both indirect and direct interventions in the primary years can help children who stutter to overcome their disorder.

Published: December 2018

Background:

Deranged energy metabolism contributes to the pathophysiology of heart failure (HF). Recent studies showed diminished free fatty acid (FFA) oxidation in experimental HF models with a shift towards oxidation of ketone bodies. However, conflicting clinical data on FFA metabolism and limited knowledge on ketone body metabolism in human HF mandate additional metabolic profiling studies. We, therefore, investigated cardiac uptake of FFAs and ketone bodies (β-hydroxybutyrate and acetoacetate) in patients with HF with reduced ejection fraction (HFrEF) or with aortic stenosis (AS)–induced left ventricular hypertrophy. We hypothesized that FFA oxidation is impaired in HFrEF and in AS and results in decreased concentrations of free carnitine, the necessary carrier for mitochondrial entry of activated FFAs, and in accumulation of metabolic intermediates.

Methods and Results:

We collected arterial and coronary sinus blood samples in patients with HFrEF (n=15), in AS patients with preserved systolic function (n=15), and in control patients (n=15). Plasma concentration gradients across the heart show significantly greater uptake of ketone bodies in patients with HFrEF than in controls. Patients with AS show significantly increased uptake of β-hydroxybutyrate and FFAs. Free carnitine concentration and concentration gradients of intermediates of FFA oxidation were comparable between groups.

Conclusions:

In conclusion, our results show significantly increased cardiac uptake of ketone bodies in patients with stable HFrEF and AS and increased uptake of FFAs in AS compared with control patients. The lack of myocardial release of acyl-carnitine species or change in free carnitine uptake suggests no impairment of FFA oxidation.

Lifetime risk (LTR) provides an absolute risk assessment during the remainder of one’s life. Few studies have focused on the LTRs of stroke and coronary heart disease (CHD), categorized by fine blood pressure in Asian populations. We aimed to assess it using a large database of a meta-analysis with the individual participant data. The present meta-analysis included 107 737 Japanese (42.4% men; mean age, 55.1 years) from 13 cohorts. During the mean follow-up of 15.2±5.3 years (1 559 136 person-years), 1922 died from stroke and 913 from CHD. We estimated risks after adjusting for competing risk of death other than the outcome of interest. The 10-year risk of stroke and CHD deaths at index age of 35 years was ≤1.9% and ≤0.3%, respectively. The LTRs of stroke death at the index age of 35 years (men/women) were 6.1%/4.8% for optimal, 5.7%/6.3% for normal, and 6.6%/6.0% for high-normal blood pressure groups, and 9.1%/7.9% for grade 1, 14.5%/10.3% for grade 2, and 14.6%/14.3% for grade 3 hypertension groups. The LTRs of CHD death similarly elevated with an increase in blood pressure but were lower (≤7.2%) than those of stroke death. In conclusion, blood pressure was clearly associated with an elevated LTR of stroke or CHD death, although the LTR of CHD death was one-half of that of stroke death in an Asian population. These results would help young people with hypertension to adopt a healthy lifestyle or start antihypertensive therapy early.

Women with a history of a hypertensive disorder of pregnancy (HDP) are at increased risk of premature cardiovascular disease. Cardiovascular risk management guidelines emphasize the need for prevention of cardiovascular disease in these women but fail to provide uniform recommendations on when and how to start cardiovascular risk assessment. The aim of this study was to identify a window of opportunity in which to start cardiovascular risk factor assessment by investigating changes in blood pressure, lipids, and fasting glucose levels over time in women with a history of an HDP. We identified women with a history of a normotensive pregnancy (n=1811) or an HDP (n=1005) within a high-risk population-based cohort study. We assessed changes in blood pressure, lipids, glucose, 10-year cardiovascular risk and the occurrence of hypertension, dyslipidemia, and diabetes mellitus longitudinally using 5 measurements at 3-year intervals. Generalized estimating equations were used for statistical analysis, with age as the time variable, adjusting for multiple comparisons using the least significant differences method. In women with an HDP, the overall prevalence of hypertension (
P
<0.0001), dyslipidemia (
P
=0.003), and diabetes mellitus (
P
<0.0001) was significantly higher. They also developed hypertension and diabetes mellitus earlier. At age 35, few women with HDP need to be screened to detect clinically relevant hypertension: 9 need to be screened to detect 1 woman with a treatment indication as opposed to 38 women with history of a normotensive pregnancy. Our data supports cardiovascular follow-up of women with a history of an HDP starting within the fourth decade of life.

We evaluated the development in blood pressure (BP) and heart rate in young women with Turner syndrome (TS) and investigated potential influencing cofactors. Twenty TS women (mean±SD, 22.9±2.3 years of age) were investigated in a 5-year prospective setting. Data were derived from a randomized controlled clinical trial investigating 2 different doses of estradiol treatment (2 mg 17β-estradiol per day and placebo or 2+2 mg 17β-estradiol per day). A control group of 12 healthy age-matched young women (mean±SD, 23.11±2.2 years of age) was examined at the end of the study. BP and lipids were monitored yearly. At the end of the study, TS (n=15) and controls were examined by 24-hour ambulatory BP monitoring. Systolic and diastolic BPs increased regardless of estradiol dose (
P
=0.005 and
P
=0.009) in TS patients, whereas heart rate decreased (
P
=0.05). Neither body mass index, height, weight, nor lipids contributed significant to the changes. There was no difference in BP, heart rate, or lipids because of treatment. At the end of the study, diastolic BP and heart rate were significantly higher in TS during day, night, and over 24 hours. Systolic BP increased insignificantly. Lipids did not change during the study period, but body mass index determined individual levels. In conclusion, systolic and diastolic BPs increase significantly in late adolescence and early adulthood in TS. It remains an enigma why BP increases early in life in TS.

Immunoproteasome Subunit β5i Promotes Ang II (Angiotensin II)–Induced Atrial Fibrillation by Targeting ATRAP (Ang II Type I Receptor–Associated Protein) Degradation in Mice
Authors: Li Jing , Wang Shuai , Zhang Yun-Long , Bai Jie , Lin Qiu-Yue , Liu Rui-Sheng , Yu Xiao-Hong , Li Hui-Hua
Published: December 2018

Atrial fibrillation (AF) is the most common type of cardiac arrhythmia and increases the risk of stroke, heart failure, and death. Ang II (angiotensin II) triggers AF, mainly through stimulation of the AT1R (Ang II type I receptor). The immunoproteasome is a highly efficient proteolytic machine derived from the constitutive proteasome, but the role it plays in regulating AT1R activation and triggering AF remains unknown. Here, we show that among the catalytic subunits, β5i (PSMB8) expression, and chymotrypsin-like activity were the most significantly upregulated in atrial tissue of Ang II–infused mice or serum from patients with AF. β5i KO (β5i knockout) in mice markedly attenuated Ang II-induced AF incidence, atrial fibrosis, inflammatory response, and oxidative stress compared with WT (wild type) animals, but injection with recombinant adeno-associated virus serotype 9–β5i increased these effects. Moreover, we found that ATRAP (AT1R-associated protein) was a target of β5i. Overexpression of ATRAP significantly attenuated Ang II-induced atrial remodeling and AF in recombinant adeno-associated virus serotype 9–β5i-injected mice. Mechanistically, Ang II upregulated β5i expression to promote ATRAP degradation, which resulted in activation of AT1R-mediated NF-κB signaling, increased NADPH oxidase activity, increased TGF (transforming growth factor)-β1/Smad signaling, and altered the expression of Kir2.1 and CX43 (connexin 43) in the atria, thereby affecting atrial remodeling and AF. In summary, this study identifies β5i as a negative regulator of ATRAP stability that contributes to AT1R activation and to AF, highlighting that targeting β5i activity may represent a potential therapeutic approach for the treatment of hypertensive AF.
New 2017 American College of Cardiology/American Heart Association High Blood Pressure Guideline

Published: December 2018

The new American College of Cardiology/American Heart Association 2017 Hypertension Guidelines lower the threshold to define hypertension, thus increasing its prevalence. The impact on populations and health systems is poorly understood. We included data from 990 subjects aged 20 to 64 years from the SALMEX cohort (Salt in Mexico; Mexico City) and determined the prevalence of hypertension and requirement for pharmacological treatment according to both Joint National Committee on the Prevention, Detection, and Treatment of High Blood Pressure 7 and American College of Cardiology/American Heart Association 2017 guidelines. The data obtained were extrapolated to sex- and age-adjusted Mexico City population, and annual costs of medical follow-up were calculated. The new definition increased the prevalence of hypertension among SALMEX cohort from 16.2% to 37.4% (18%–39.3% after adjusting to Mexico City population). The proportion of subjects that require pharmacological and nonpharmacological treatment increased from 17.7% to 19.0% and from 17.7% to 37.4%, respectively (19.4%–21.8% for pharmacological and 19.4%–39.3% for nonpharmacological treatment, after adjusting to Mexico City population). Annual costs of medical follow-up for subjects with hypertension in Mexico City would increase an estimated $59 278 928. The requirement to initiate pharmacological treatment was similar when assessed by Framingham risk score with lipids or with body mass index compared with the Atherosclerotic Cardiovascular Disease score, with correlation κ indexes of 0.981 and 0.972, respectively. On the basis of these results, Framingham body mass index represents an attractive and potentially cost-effective alternative to assess cardiovascular risk. In conclusion, the adoption of the new guidelines in Mexican population has implications not only on its prevalence but also on medical follow-up costs. A pharmacoeconomic model is required to assess the actual financial impact.

Published: December 2018

Women with thoracic aortic aneurysms (TAAs) have higher risk of acute aortic syndromes and death than men. We have shown that TAA growth is accelerated in women, helping explain the sex differences in TAA outcomes. Since aortic stiffness reflects the health of the aorta, we sought to determine the sex-specific role of aortic stiffness on TAA growth. One hundred thirty unoperated people with TAA were recruited. Maximal aneurysm size at the oldest and latest imaging studies was measured to calculate TAA growth rate. Aortic stiffness was assessed by carotid-femoral pulse wave velocity (cfPWV) using applanation tonometry. Multivariable linear regression adjusted for confounders assessed the association of cfPWV with TAA growth. Seventy-three percent of subjects were men. Mean±SD age, baseline aneurysm size, follow-up time, and cfPWV were 62.5±11.5 years, 45.3±4.0 mm, 3.3±3.0 years and 9.6±3.5 m/s, and not different based on sex. TAA growth rate was 0.96±1.00 mm/y in women and 0.45±0.58 mm/y in men (
P
=0.006). In the whole group, cfPWV was independently associated with TAA growth (β±SE: 0.06±0.02,
P
=0.02). However, in sex-specific analyses cfPWV was independently associated with faster aneurysm growth in women (β±SE: 0.21±0.09,
P
=0.03), but not in men (β±SE: −0.002±0.02,
P
=0.94), with a significant sex×cfPWV interaction (
P
<0.0001). In patients with TAA, aneurysm growth is more than twice as fast in women than men, and aortic stiffness is associated with greater TAA growth in women, but not in men. Our findings highlight greater aortic stiffness as an important correlate of TAA expansion in women.
PI3Kγ (Phosphoinositide 3-Kinase-γ) Inhibition Attenuates Tissue-Type Plasminogen Activator–Induced Brain Hemorrhage and Improves Microvascular Patency After Embolic Stroke
Authors: Jin Rong , Xiao Adam Y. , Li Jarvis , Wang Min , Li Guohong
Published: December 2018

Genetic and pharmacological inhibition of the PI3Kγ (phosphoinositide 3-kinase-γ) exerts anti-inflammatory and protective effects in a number of inflammatory and autoimmune diseases. SHRs (spontaneously hypertensive rats) subjected to embolic middle cerebral occlusion were treated with AS605240 (30 mg/kg) at 2 or 4 hours, tPA (tissue-type plasminogen activator; 10 mg/kg) at 2 or 6 hours, or AS605240 at 4 hours plus tPA at 6 hours. Infarct volume, brain hemorrhage, neurological function, microvascular thrombosis, and cerebral microvessel patency were examined. We found that treatment with AS605240 alone at 2 hours or the combination treatment with AS605240 at 4 hours and tPA at 6 hours significantly reduced infarct volume and neurological deficits at 3 days after stroke compared with ischemic rats treated with saline, AS605240 alone at 4 hours, and tPA alone at 6 hours. Moreover, the combination treatment effectively prevented the delayed tPA-induced cerebral hemorrhage. These protective effects are associated with reduced disruption of the blood-brain barrier, reduced downstream microvascular thrombosis, and improved microvascular patency by AS605240. Inhibition of the NF-κB (nuclear transcription factor-κB)–dependent MMP (matrix metalloproteinase)-9 and PAI-1 (plasminogen activator inhibitor-1) in the ischemic brain endothelium may underlie the neurovascular protective effect of AS605240. In addition, the combination treatment significantly reduced circulating platelet P-selectin expression and platelet-leukocyte aggregation compared with ischemic rats treated with saline or tPA alone at 6 hours. In conclusion, inhibition of PI3Kγ with AS605240 reduces delayed tPA-induced intracerebral hemorrhage and improves microvascular patency, which likely contributes to neuroprotective effect of the combination treatment.

A chronic and gradual increase in pulse pressure (PP) is associated with cognitive decline and dementia in older individuals, but the mechanisms remain ill-defined. We hypothesized that a chronic elevation of PP would cause brain microvascular endothelial mechanical stress, damage the neurovascular unit, and ultimately induce cognitive impairment in mice, potentially contributing to the progression of vascular dementia and Alzheimer disease. To test our hypothesis, male control wild-type mice and Alzheimer disease model APP/PS1 (amyloid precursor protein/presenilin 1) mice were exposed to a transverse aortic constriction for 6 weeks, creating a PP overload in the right carotid (ipsilateral). We show that the transverse aortic constriction procedure associated with high PP induces a cascade of vascular damages in the ipsilateral parenchymal microcirculation: in wild-type mice, it impairs endothelial dilatory and blood brain barrier functions and causes microbleeds, a reduction in microvascular density, microvascular cell death by apoptosis, leading to severe hypoperfusion and parenchymal cell senescence. These damages were associated with brain inflammation and a significant reduction in learning and spatial memories. In APP/PS1 mice, that endogenously display severe cerebral vascular dysfunctions, microbleeds, parenchymal inflammation and cognitive dysfunction, transverse aortic constriction–induced high PP further aggravates cerebrovascular damage, Aβ (beta-amyloid) accumulation, and prevents learning. Our study, therefore, demonstrates that brain microvessels are vulnerable to a high PP and mechanical stress associated with transverse aortic constriction, promoting severe vascular dysfunction, disruption of the neurovascular unit, and cognitive decline. Hence, chronic elevated amplitude of the PP could contribute to the development and progression of vascular dementia including Alzheimer disease.

Published: December 2018

Physalaemus olfersii was described by M.H.K. Lichtenstein and E.K. Martens in 1856 based on two syntypes collected by I.M. Olfers between the years 1818 and 1819. Due to the brevity of it’s original description and high interpopulational variation, a taxonomic review of material assigned to the species is proposed. Morphological comparisons allowed us to associate the syntype of P. olfersii to populations distributed between the state of Espírito Santo and of São Paulo to which the southern limit is the to the municipality of São Paulo. Historical documents allowed us to define an area within Serra do Mar mountain range as the type locality of the species. Morphological and acoutics comparisons of P. olfersii from different localities in southern and southeastern Brazil revealed considerable variation among populations. Differences in call parameters and morphology, led us to conclude that three more species where under the name P. olfersii: Physalaemus lateristriga (Steindachner, 1864) comb. nov. and two new species, Physalaemus feioi sp. nov. and P. orophilus sp. nov.
Arcanobisium, a remarkable new genus, representing a new subfamily with a relictual distribution from eastern Spain (Arachnida: Pseudoscorpiones: Syarinidae)
Authors: ZARAGOZA JUAN A.
Published: December 2018

Arcanobisium gen. nov. is described for Arcanobisium comasi sp. nov., from a limestone cave in the Valencian Community, Castellón province, Spain. By its unique features, compared to other syarinids, it warrants the creation of a new subfamily, Arcanobisiinae, for its accommodation. Some characters of the Syarinidae are evaluated and the genera Chitrellina Muchmore, 1996, Hadoblothrus Beier, 1952, Microcreagrella Beier, 1961 and Microcreagrina Beier, 1961 are transferred to the subfamily Ideobisiinae from the Chitrellinae. A key to the subfamilies of Syarinidae is given. The relictual status of the new subfamily is discussed.

Published: December 2018

Seventeen warthogs were harvested from their natural habitat during the winter hunting seasons of May to July 2001 and May to June 2002. Samples (200ml each) were collected and weighed from the stomach, cecum and colon of each animal for protozoal counts. Telamodinium onyx was the only protozoa present in seven animals and the predominant species in all others. Megadinium aethiopicum was observed in eight animals, while Teratodinium sphaeredon was present in two warthogs. Several different species of protozoa were seen in a few animals, two of which belong to the family Ophryoscolecidae and are considered to be normal inhabitants in the rumen (Diplodinium dentatum and Ophryoscolex purkynjei).

A new species of parrotfish, Sparisoma rocha sp. n., is described from Trindade Island off South-eastern Brazil. It differs from its Western Atlantic congeners by the unique colour pattern of live and freshly preserved individuals: initial phase red overall with a brownish shade from lower jaw to over the abdominal cavity, sparse orange blotches on head, and pale circumpeduncular band; terminal phase reddish brown with orange stripe from jaw angle to end of preopercle, sparse orange blotches on head, three pinkish to reddish stripes from about midline to dorsum, from midline to belly pale greyish green to whitish with suffusion of pale reddish brown, a black spot on base of pectoral fins and a bright-yellow blotch below this spot. Additionally, mitochondrial 12S and 16S rRNA loci sequences do not match any known Sparisoma species. The new parrotfish increases to six the species of the genus Sparisoma recorded from South-western Atlantic.

Published: December 2018

We studied the original material of several species of Nippostrongylinae (Nematoda: Heligmonellidae) described by H. A. Baylis in muroid rodents from Nigeria: Heligmonina praomyos Baylis, 1928, Heligmonina oenomyos Baylis, 1928, Heligmonina cricetomyos Baylis, 1928, Neoheligmonella affinis (Baylis, 1928), Neoheligmonella intermedia (Baylis, 1928), Neoheligmonella gracilis (Baylis, 1928), Neoheligmonella impudica (Baylis, 1928), Neoheligmonella moennigi (Baylis, 1928), and Heligmonoides murina Baylis, 1928. The comparison of the material examined to the original descriptions, revealed the presence of at least seven other species mixed among the type and voucher material. For the nominal species of Baylis lectotypes and paralectotypes are designated. Due to the poor condition of the material, the other species found were only identifiable to generic level. Most of them were coparasitic with Baylis’ species. The following species associations were found: Heligmonina praomyos + Neoheligmonella moennigi, Heligmonina oenomyos + Neoheligmonella sp. 1, Heligmonina cricetomyos + Neoheligmonella moennigi, Heligmonina sp. 2 + Neoheligmonella sp. 4. Tables with the identification of the specimens studied are provided. New morphometrical data and illustrations on this material are also provided, particularly on the anterior part of the body and genital apparatus in the females. The occurrence of coparasitism as a frequent phenomenon among the Trichostrongylina is highlighted.

A new species of Philodromus (Artanes) from Macedonia, Greece (Araneae: Philodromidae)
Authors: MUSTER CHRISTOPH , VAN KEER JOHAN
Published: December 2018

Artanes Thorell, 1870 constitutes a well-defined distal clade within the collective genus Philodromus Walckenaer, 1826 and was assigned to subgeneric rank by Muster (2009). Thereupon Logunov and Kunt (2010) suggested re-elevation of Artanes to genus level, but this proposal is not followed here with reference to the phylogenetic reconstructions presented in Muster (2009). In particular, delineation and synapomorphies of closely related genera and species groups remain to be defined. The west-Palearctic species of the taxon have recently been revised to comprise seven Mediterranean endemics and five more widespread species (Muster 2009). A further species from Turkey was described by Logunov and Kunt (2010) which we had previously considered a geographic variant of P. poecilus (Thorell, 1872) (see remarks on intraspecific variation in this species in Muster 2009). Shortly after publication of the 2009 study, a series of specimens from pine trees in Macedonia, Greece was sampled by a group of Belgian arachnologists that could not be allocated to any of the known species. Due to similarities in the shape of the receptacula, we originally assumed to have found more females and the unknown male of P. pentheri Muster, 2009. However, a close examination revealed important structural differences in the vulvae, most importantly, the newly collected females show a voluminous, sclerotised bursa copulatrix. In this paper we therefore describe a further species, belonging to the P. poecilus group of the Philodromus subgenus Artanes. This is a nice example in illustrating how the availability of a modern revision may trigger new findings.

The genus Klyngon Hansson is revised and expanded to include 13 species, 11 of which are newly described: K. albicornis, K. aulacis, K. brasilense, K. copaiferae, K. costalimai, K. gibberum, K. guimaraesi, K. hortense, K. pegosoma, K. petalon, K. serjaniae. The inclusion of the new species necessitates a change of the morphological definition of the genus and diagnostic characters are modified or abandoned and new characters are introduced. The new species are described and diagnosed and all species are included in a key. The variation in the number of setae on midlobe of mesoscutum, scutellum and submarginal vein is discussed in terms of diagnostic characters for the subfamily, and the consequences of this variation for the identification of the genus with existing keys are highlighted, with a suggested solution to this problem. Biological records are available for 7 of the species, and all records are from unidentified galls, 4 species from Copaifera langsdorffii (Fabaceae), 2 species from Serjania mexicana (Sapindaceae), and 1 species from an unidentified liana. Klyngon is regarded as a basal group within the tribe Entedonini and the association with galls is here speculated to be a primitive biology for the tribe.

Authors: JIA FENGLONG
Published: December 2018

The Oriental genus Megagraphydrus Hansen, 1999 was originally established for five species described from China (Taiwan), Thailand, Sri Lanka, West Malaysia and Vietnam. Subsequently, Hebauer (2000) described an additional five species, including the first species from Mainland China (Megagraphydrus anhuianus Hebauer, 2000), and provided a key to all known species at that time. In 2009, Minoshima & Fujiwara described M. luteilateralis from Japan, bring the total number of described species to eleven. Up to now, two of these were known from Mainland China: Megagraphydrus anhuianus Hebauer and Megagraphydrus attenuatus Hansen.

Taxonomic revision of the wide-front fiddler crabs of the Uca lactea group (Crustacea: Decapoda: Brachyura: Ocypodidae) in the Indo-West Pacific
Authors: NADERLOO REZA , TÜRKAY MICHAEL , CHEN †HUI-LIAN
Published: December 2018

The Indo-West Pacific broad-front fiddler crabs, formerly attributed to the "lactea species-group" are revised. The subgenus Uca (Austruca) Bott, 1973, is here revived for accommodating the informal "lactea species-group". Uca (Austruca) presently covers 7 species, partly with a restricted regional distribution, of which one (Uca cryptica sp. nov. from Indonesia) is new to science.
A revision of the genus Nomisia in Greece and neighboring regions with the description of two new species
Authors: CHATZAKI M.
Published: December 2018

In this revision ten species of the genus Nomisia are diagnosed and taxonomically commented. Of them, five are well established in the previous literature, namely, N. aussereri (L. Koch, 1872), N. exornata (C. L. Koch, 1839), N. ripariensis (O. P.Cambridge, 1872), N. orientalis Dalmas, 1921 and N. palaestina (O. P.Cambridge, 1872). N. recepta (Pavesi, 1880) and N. excerpta (O. P.Cambridge, 1872) are critically compared and re-established. N. excerpta shows wide intra-specific variation, possibly leading to new species. N. conigera (Spassky, 1941) is here synonymized with the recently described N. anatolica Seyyar, Ayyildiz & Topçu, 2009. Finally two new species are described, namely, N. levyi n. sp. and N. peloponnesiaca n. sp. From the above list, only seven species are recorded in Greece, leaving out N. orientalis, N. recepta and N. conigera.

Two new nematode species from Saldanha Bay, South Africa: Perepsilonema benguelae sp. nov. and Leptepsilonema saldanhae sp. nov. (Desmodorida, Epsilonematidae)
Authors: HENDRICKS MARTIN G. J. , GIBBONS MARK J.
Published: December 2018

Perepsilonema benguelae sp. nov. and Leptepsilonema saldanhae sp. nov. are described and illustrated from coarse sand sediments in Saldanha Bay, along the west coast of South Africa. Perepsilonema benguelae sp. nov. is characterised by a large swollen body in the genital region, the annuli are not clearly orientated into anteriorly and posteriorly directed margins and copulatory thorns are restricted to three pairs in the precloacal region. In Leptepsilonema saldanhae sp. nov. the somatic setae in the pharyngeal region are very long and the first ambulatory setae of the external subventral row are short. Other distinguishing features include the shape of the amphidial fovea and the copulatory apparatus, and the presence of six ventro-lateral copulatory thorns around the cloaca. These descriptions are the first for the family Epsilonematidae from the west coast of South Africa.
Two new cryptic Leptophyes species from southern Italy (Orthoptera: Tettigoniidae)
Authors: KLEUKERS ROY M. J. C. , ODÉ BAUDEWIJN , FONTANA PAOLO
Published: December 2018

In this paper two new species of Leptophyes from southern Italy are described, L. calabra n. sp. and L. sicula n. sp.. Both species are similar to the common L. punctatissima and the recently described L. lisae from Greece, but can be identified by a combination of morphological and biacoustical characters. Descriptions of both species are provided and an illustrated key to the European species of Leptophyes is presented. These new findings are remarkable as the genus Leptophyes harbours only 15 species worldwide. This study suggests that the Leptophyes punctatissima group in southern Europe is in need of a thorough survey. It is essential that bioacoustical information be involved in this study.

(Nicaragua, Costa Rica, Panama), P. rubens sp. n. (Costa Rica, Panama) and P. wyandoti sp. n. (Nicaragua, Costa Rica, Panama, Ecuador). The overlooked precedence of P. jelskii Chevrolat over P. maculiventris Chevrolat is reestablished. Conophoria cana dispersa Casey is a new junior synonym of P. canus Champion. Habitus images for most species and an identification key are provided.
Taxonomic review of the species of Neocorynura (Hymenoptera: Halictidae: Augochlorini) inhabiting Argentina and Paraguay
Authors: SMITH-PARDO ALLAN H.
Published: December 2018

A review of the species of the bee genus Neocorynura occurring in Argentina and Paraguay is provided. Four new species are described: Neocorynura tangophyla, Neocorynura gaucha, Neocorynura guarani, and Neocorynura sophia. The name Neocorynura pseudobaccha (Cockerell) is resurrected, it had previously been synonymized under Neocorynura jucunda (Smith). In total, eight species are known to occur in these two countries. Even though six additional species of Neocorynura have been considered to also be distributed in Argentina and Paraguay, their dubious occurrence in these countries may be due to imprecise information in the primary references or to collection data (specimen’s deposition). No specimens of such species were available in any of the collections consulted for this taxonomic study. Comments on the systematics and biogeography (including new distribution records), as well as species identification keys, are presented.
