Despite the urban and landscape impact caused by Drymoea veliterna (Druce, 1885) (Lepidoptera: Geometridae) larvae on trees of the genus Croton L. (Euphorbiaceae) in the Neotropics, there is no information about its biology and reproductive traits. In this study, we describe the life cycle and reproductive traits of this species. Its life cycle lasts approximately 56 days, the larvae develop during 24 days on average and the longevity of the females is 7 days on average. Females have an average fecundity of 207 eggs. Regarding their reproductive system, the presence of previtellogenic eggs in the reproductive tract of the females is emphasized. The bursa copulatrix and a highly sclerotized signum is depicted. The number of spermatophores found in the reproductive tract of the females was quantified. Male and female genitalia were schematized.

Although a recent revision of the genus Glyphidops Enderlein covered most its known, some of the Brazilian forms were not surveyed. Here we take advantage of the excellent morphological work available in the literature and redescribe Glyphidops (Glyphidops) filosus, based on 91 specimens (43 males and 48 females) from the States of Amazonas and Goiás, including Brasília, Brazil. We also provide a study of male genitalia using scanning electron microscopy (SEM) and female genitalia and spermathecae, using light microscopy (LM). We present descriptions of the following structures in male genitalia: epandrium, hypandrium, surstyli, cerci and sections of aedeagus, and in female genitalia: oviscape, bursa copulatrix, ‘S’ bend and spermatheca. An update list of Brazilian species of Glyphidops Enderlein is also presented.

The spectacular variability that typically characterizes male genital traits has largely been attributed to the role of sexual selection. Among the evolutionary mechanisms proposed to account for this diversity, two processes in particular have generated considerable interest. On the one hand, females may exploit postcopulatory mechanisms of selection to favour males with preferred genital traits (cryptic female choice; CFC), while on the other hand females may evolve structures or behaviours that mitigate the direct costs imposed by male genitalia (sexual conflict; SC). A critical but rarely explored assumption underlying both processes is that male and female reproductive traits coevolve, either via the classic Fisherian model of preference-trait coevolution (CFC) or through sexually antagonistic selection (SC). Here, we provide evidence for this prediction in the guppy ( Poecilia reticulata ), a polyandrous livebearing fish in which males transfer sperm internally to females via consensual and forced matings. Our results from a paternal half-sibling breeding design reveal substantial levels of additive genetic variation underlying male genital size and morphology—two traits known to predict mating success during non-consensual matings. Our subsequent finding that physically interacting female genital traits exhibit corresponding levels of genetic (co)variation reveals the potential intersexual coevolutionary dynamics of male and female genitalia, thereby fulfilling a fundamental assumption underlying CFC and SC theory.

Background: The reproductive physiology of goat is least understood compared to cattle, sheep and pig and most of the description of goat is usually made as if it is identical to sheep. The biometric and histomorphometric analyses of female reproductive system of Black Bengal goats were performed in this study. Methods: During October 2016 to February 2019 a total of 200 female reproductive tracts (50 from each age category of ≤ 6 months (m), 7-12 m, 13-18 m and 19-24 m) were collected and examined from various slaughter houses of Kishoreganj district of Bangladesh. For biometric study the length, width and weight of different segments of female reproductive tracts were measured. In addition, the morphometry of different parts of female genitalia was analyzed at histology. One-way ANOVA with Bonferroni's Multiple Comparison Test was performed to compare between different age groups and paired organs. Results: Overall the size of most parts of the reproductive tract of goats increased with ages and 19-24 m group had the highest values. In paired organs such as ovaries, uterine tubes and uterine horns, the right organs were significantly bigger than the left one. Similarly, at morphometric analysis, the length of all histologic parts such as cortex and medulla of ovary, tunica mucosa, tunica muscularis and tunica serosa of uterine tube, uterus, vagina and vulva increased significantly with ages and the highest values observed at age category of 19-24 m. Conclusion: The knowledge of the biometrical and morphometric parameters of female genitalia of Black Bengal goats would help in performing artificial insemination, pregnancy diagnosis and treating infertility related problems.

AbstractThe internal reproductive system of adult males of Spodoptera littoralis (Boisd.) is described, and changes in colour of a secretion in the ductus ejaculatorius simplex with age and mated status are noted. Virgin males 0–7 days old and mated males 0–7 days after mating were killed and the colour of the secretion in the simplex compared with colour chips in the Munsell book of color (1929–1942). The results showed that the simplex of newly emerged males was colourless or pale yellow, but after two days an orange pigmented secretion had begun to accumulate in 61·3% of males examined. By four days this pigment had darkened to deep red in 96·4% of virgin males. On mating, a portion of this secretion was incorporated into the spermatophore while the rest was passed into the bursa copulatrix of the female, leaving the simplex of newly mated males colourless. There was. however, a gradual re-accumulation of the pigmented secretion after mating through yellow, orange and finally to deep red. This accumulation of the red pigment was slightly slower in the mated males than in virgins, and three days after mating only 29·6% of the males had a red simplex compared with 78·8% of three-day-old virgin males. The potential use of these changes in colour to determine the mated status of field-caught males is discussed.

Three species of the genus Wockia Heinemann, 1870, which are so far known in Russia are reviewed; their male and female genitalia are illustrated, and a key for identification is provided. Two species, W. koreana Sohn, 2008, and W. magna Sohn, 2014, which were recently described from East Asia, are for the first time reported from Russia. The investigation of the holotype of W. funebrella Heinemann, 1870, discovered in the collection of the Zoological Institute RAS (St Petersburg), confirmed that this species is a junior subjective synonym of W. asperipunctella (Bruand, 1851). The distribution of Palaearctic species of the genus is discussed shortly.

AbstractThe genus Endeius Coiffait & Sáiz, 1968 (Staphylininae: Staphylinini), distributed from Chile and Argentina through Juan Fernández Is. and Galapagos Is., is revised using characters of external morphology and male and female genitalia. Endeius comprises seven valid species: E. punctipennis (Solier), E. nitidipennis (Solier), E. subpunctipennis Coiffait & Sáiz, E. loensis Coiffait & Sáiz, E. franzi Sáiz, E. lugubris Sáiz and E. ovaliceps Coiffait. Belonuchus multipunctatus (Coiffait), comb. nov., is excluded from Endeius. An identification key to all species of the genus is provided. Monophyly of Endeius, as considered in the present study, is supported by one synapomorphy from the external morphology. Within the genus, the best supported subgroup consists of E. punctipennis (Solier), E. subpunctipennis Coiffait & Sáiz, E. loensis Coiffait & Sáiz and E. ovaliceps Coiffait.

AbstractMallochianamyia Santos-Neto was proposed as a replacement name for Gayomyia Malloch, 1933 (preoccupied by Gayomyia Banks, 1913), an unplaced genus of acalyptrate Diptera from Chile and Argentina. The genus comprises 12 species: M. cladostyla sp. n.; M. fenestrata sp. n.; M. flavitibia sp. n.; M. furcata sp. n.; M. gallina sp. n.; M. latigena sp. n.; M. magnipalpis sp. n.; M. nigrohalterata (Malloch) comb. n.; M. penai sp. n.; M. setosa sp. n.; M. truncata sp. n.; M. vexans sp. n. All new species are illustrated and a key to species of Mallochianamyia is provided. The monophyly of the genus is supported by three characters of the male and female genitalia. Mallochianamyia is most closely related to the New World genera Paraleucopis Malloch and Schizostomyia Malloch and an undescribed Australian genus. The group cannot be placed in any established family as currently defined, although there are affinities to some families in the Asteioinea sensu J. F. McAlpine (1989). Research on the morphology and relationships of genera related to Mallochianamyia is required to clarify the familial status of the group.

Intravenous Inoculation

Although XMRV dissemination in humans is a matter of debate, the prostate of select patients seem to harbor XMRV, which raises questions about its potential route of transmission. We established a model of infection in rhesus macaques inoculated with XMRV. In spite of the intravenous inoculation, all infected macaques exhibited readily detectable XMRV signal in the reproductive tract of all 4 males and 1 female during both acute and chronic infection stages. XMRV showed explosive growth in the acini of prostate during acute but not chronic infection. In seminal vesicles, epididymis, and testes, XMRV protein production was detected throughout infection in interstitial or epithelial cells. In the female monkey, epithelial cells in the cervix and vagina were also positive for XMRV gag. The ready detection of XMRV in the reproductive tract of male and female macaques infected intravenously suggests the potential for sexual transmission for XMRV.
