RESUMO

The generic level segregation of the formerly unified taxa Nyctobrya Boursin, 1957 and Bryopsis Boursin, 1970 is discussed; the second one is reinstated as a genus, on the basis of apomorphic features in the male genitalia (Bryopsis stat. rev.). The large genus Bryophila Treitschke, 1825 is briefly characterized, in order to assess the specific identity of the formerly misinterpreted Bryophila perloides Guenée, 1852, the only European member of its species-group. So far as is known, B. perloides (stat. rev.) inhabits the southernmost, pericoastal area of Andalusia (Spain), and is known to date from five specimens. It is, thus, to be included in the Iberian and European checklists of Noctuidae. All other described species of the perloides species-group are North African. They are reviewed and their types checked; the adults, as well as their genitalia, are illustrated. Genitalia of all holotypes/syntypes are studied. Also, lectotypes are designated for B. perloides, B. squamosa Schwingenschuss, 1936 and B. barbaria Schawerda, 1934.

RESUMO

The ground beetle genus Pterostichus Bonelli has diversified in regions including the Far East, but taxonomic issues remain even at the species level. This study presents taxonomic and nomenclatural changes in three species of Pterostichus from the Far East: P. (Petrophilus) eximius Morawitz, P. (Lenapterus) wellschmiedi Kirschenhofer, and P. (L.) subrugosus Straneo. The analyses are based on comparative studies of the endophallus of male genitalia, which is taxonomically useful in Carabidae but has not been examined in these species. The first species, P. eximius, has been treated as a monotypic species that is widely distributed in Eastern Siberia, the Russian Far East, and adjacent regions, but our results revealed that populations from Rishiri-tô and the Sakhalin islands are distinct from the nominotypical population from Transbaikalia. The name for the Sakhalin population, which was synonymized with P. eximius, is reinstated as subspecies P. eximius sachalinensis stat. nov., and the Rishiri-tô population is described as Pterostichus eximius rishiridakensis ssp. nov. Conspecificity (syn. nov.) was confirmed for P. wellschmiedi, which was described from southern Sakhalin, and P. marginatus Matsumura, which was described earlier from southern Sakhalin. No conspicuous differences in the endophallus structure were found between P. subrugosus, which was described from Hokkaidô, and P. marginatus, although differences are recognized in the elytral sculptures and in the metallic luster of the dorsal surface. The taxon was thus downgraded to subspecies P. marginatus subrugosus stat. nov.

RESUMO

A new species of Aricoris Westwood, 1851, until now treated erroneously as Aricoris tutana (Godart, [1824]), is described and illustrated from the Neotropical Cerrado savanna. Aricoris emeryi Callaghan, Lemes Kaminski, sp. nov. can be identified by a set of characters on wings and male genitalia that differentiates it from other species belonging to the constantius group.

RESUMO

A new species of a tessaratomid bug, namely Pycanum occidentale sp. nov, is described with comments on the other species of the genus found in India. This species can be easily distinguished from the other species of Pycanum by the shape of male genitalia, especially pygophore and parameres. This becomes the fourth species of Pycanum in India and the first one from western India. A key to the extant species of the genus is also provided along with diagnostic images of pygophores and parameres for three species found in India.

RESUMO

The taxonomy of the subgenus Ashima of the genus Phortica is revised. A cladistic analysis of 66 morphological characters is conducted, covering 35 species (28 known and 7 new species: Phortica efragmentata sp. nov., P. andreagigoni sp. nov., P. watabei sp. nov., P. halimunensis sp. nov., P. akutsui sp. nov., P. kerinciensis sp. nov., and P. takehiroi sp. nov.) which correspond to 71.4% of 49 total spp. of Ashima. The resulting cladogram shows that the studied species are separated into several clades/subclades/cluster each highly supported with specific synapomorphies. Those clades/subclades/cluster are newly defined as the following species groups, subgroups or complex: the afoliolata, foliiseta, nigrifoliiseta and angulata species groups; the foliiseta, tanabei, nigrifoliiseta and glabra species subgroups; and the foliiseta species complex. The subgenus Ashima is peculiar in having the asymmetric male genitalia as the ground plan and showing the antisymmetry (i.e. intraspecific mirror-image variation) in some species but the directional asymmetry (i.e. side-fixed asymmetry) in others. The evolution of genital asymmetry in this subgenus is estimated by mapping the states (symmetry, directional asymmetry and antisymmetry) of bilateral structures of male genitalia on the cladogram. This ancestral state reconstruction estimates that the directional asymmetry of male genitalia has evolved at the ancestor of this subgenus and then changed to the antisymmetric state independently in two lineages, the angulata + nigrifoliiseta species groups and the foliiseta species complex. In this study, a standardized terminology recently proposed for the male terminalia of Drosophila melanogaster is extendedly adopted to describe the morphology of male terminalia in the subgenus Ashima, one group of the subfamily Steganinae.

RESUMO

BACKGROUND: the purpose of this study was to evaluate the effects of sleep deprivation on semen analyses, hormone levels and testicular histopathology in men. METHODS: this review will be included in a qualified case-control study. The search strategy will be implemented in PubMed, Embase, Web of science, Cochrane library, China National knowledge Infrastructure database, Wanfang Database, and the Cochrane library. We will solicit both English and Chinese case-control studies published from its beginning to July 31, 2020. The 2 examiners will independently screen, select research, extract data and evaluate quality. We use Revman5.3 software to generate funnel map, heterogeneity assessment, data analysis, subgroup analysis and sensitivity analysis. RESULTS: in the current meta-analysis, we will provide some more practical and targeted results for the study of the effects of sleep on the male reproductive system, and sum up the main limitations of previous studies. CONCLUSION: this study will provide new evidence for the effect of sleep on male reproductive system.

RESUMO

New information is given on the distribution of Cheilosia Meigen species (Diptera, Syrphidae) in Central Asia, together with a description of two new species. The new species, Cheilosia teneripilosa sp. nov. and Cheilosia vadimi sp. nov., belong to the subgenus Montanocheila Barkalov. Cheilosia teneripilosa differs from its close allies by a set of the following characters: eyes with long black hairs, legs of male completely black, abdomen predominantly with light hairs, superior lobe of hypandrium with a very small left process. Cheilosia vadimi is close to C. kirgizorum Peck, but differs by shorter hairs on the eyes and scutum, and a completely different shape of the superior lobe of the hypandrium. A revised key is given to the 'group C' species of Cheilosia from Central Asia (those with haired eyes, bare face and absence of strong bristles on scutellar hind margin). The descriptions of the new species are accompanied by drawings of the head and male genitalia.

RESUMO

Sabethes (Sabethoides) glaucodaemon was described for the first time by Dyar Shannon (1925) based on the adult female. Later, descriptions of the male genitalia and parts of the fourth-instar larva and pupa were published by other authors. No one has described the female genitalia or made a complete description of the larva and pupa. The aim of this study was to redescribe Sa. glaucodaemon in the adult stage, including the male and female genitalia, and the pupa and fourth-instar larva. All stages are illustrated. Distinctions from Sa. (Sbo.) tridentatus are discussed.

RESUMO

The bivalved crustacean ostracods have the richest fossil record of any arthropod group and display complex reproductive strategies contributing to their evolutionary success. Sexual reproduction involving giant sperm, shared by three superfamilies of living ostracod crustaceans, is among the most fascinating behaviours. However, the origin and evolution of this reproductive mechanism has remained largely unexplored because fossil preservation of such features is extremely rare. Here, we report exceptionally preserved ostracods with soft parts (appendages and reproductive organs) in a single piece of mid-Cretaceous Kachin amber (approximately 100 Myr old). The ostracod assemblage is composed of 39 individuals. Thirty-one individuals belong to a new species and genus, Myanmarcypris hui gen. et sp. nov., exhibiting an ontogenetic sequence from juveniles to adults (male and female). Seven individuals are assigned to Thalassocypria sp. (Cypridoidea, Candonidae, Paracypridinae) and one to Sanyuania sp. (Cytheroidea, Loxoconchidae). Our micro-CT reconstruction provides direct evidence of the male clasper, sperm pumps (Zenker organs), hemipenes, eggs and female seminal receptacles with giant sperm. Our results reveal that the reproduction behavioural repertoire, which is associated with considerable morphological adaptations, has remained unchanged over at least 100 million years-a paramount example of evolutionary stasis. These results also double the age of the oldest unequivocal fossil animal sperm. This discovery highlights the capacity of amber to document invertebrate soft parts that are rarely recorded by other depositional environments.

RESUMO

The outbreak of CoronaVirus Disease19 (COVID19) in December 2019 posed a serious threat to public safety, and its rapid spread caused a global health emergency. Clinical data show that in addition to respiratory system damage, some male patients with COVID-19 are also accompanied by abnormal renal function and even renal damage. As the main receptor of syndrome coronavirus 2 (SARS-CoV-2), angiotensin converting enzyme 2 (ACE2) is also found to be highly expressed not only in respiratory mucosa and alveolar epithelial cells, but also in renal tubule cells, testicular Leydig cells and seminiferous tubule cells. This suggests that SARS-CoV-2 has the possibility of infecting the male reproductive system, and the recent detection of SARS-CoV-2 in the patient's semen further confirms this theory. In previous studies, it has been found that ACE2 has the ability to regulate autophagy. Not only that, recent studies have also found that SARS-CoV-2 infection can also lead to a reduction in autophagy. All of these associate SARS-CoV-2 with autophagy. Furthermore, autophagy has been shown to have an effect on male reproduction in many studies. Based on these, we propose the hypothesis that SARS-CoV-2 affects male reproductive function by regulating autophagy. This hypothesis may provide a new idea for future treatment of COVID-19 male patients with reproductive function injury, and it can also prompt medical staff and patients to consciously check their reproductive function.
