Discovery of five new species of Allacta from Yunnan and Hainan, China (Blattodea, Pseudophyllodromiidae).

We examined new Allacta materials from Yunnan and Hainan Province, China, and discovered new species using both morphological and molecular species delimitation (ABGD) methods. Five new species are described: A.bifolium Li & Wang, sp. nov., A.hemiptera Li & Wang, sp. nov., A.lunulara Li & Wang, sp. nov., A.redacta Li & Wang, sp. nov., and A.unicaudata Li & Wang, sp. nov. All five species are placed under the hamifera species group. An updated key and checklist of Allacta species from China are provided.

MicroRNA expression in specific segments of the pig periovulatory internal genital tract is differentially regulated by semen or by seminal plasma.

microRNAs play pivotal roles during mammalian reproduction, including the cross-talk between gametes, embryos and the maternal genital tract. Mating induces changes in the expression of mRNA transcripts in the female, but whether miRNAs are involved remains to be elucidated. In the current study, we mapped 181 miRNAs in the porcine peri-ovulatory female reproductive tract: Cervix (Cvx), distal and proximal uterus (Dist-Ut, Prox-Ut), Utero-tubal-junction (UTJ), isthmus (Isth), ampulla (Amp), and infundibulum (Inf) when exposed to semen (natural mating (NM) or artificial insemination (AI-P1)) or to infusions of sperm-free seminal plasma (SP): the first 10 mL of the sperm rich fraction (SP-P1) or the entire ejaculate (SP-E). Among the most interesting findings, NM decreased mir-671, implicated in uterine development and pregnancy loss prior to embryo implantation, in Cvx, Dist-UT, Prox-UT, Isth, and Inf, while it increased in Amp. NM and SP-E induced the downregulation of miR-let7A-1 (Dist-UT, Prox-UT), a regulator of immunity during pregnancy. miR-34C-1, a regulator of endometrial receptivity gene expression, was increased in Dist-UT, UTJ and Amp (NM), in Prox-UT (AI-P1), and in Amp (SP-P1). miR-296, a modulator of the inflammatory response and apoptosis, was upregulated in the UTJ (all treatments). NM elicited the highest miRNA activity in the sperm reservoir (UTJ), suggesting that key-regulators such as miR-34c or miR-296 may modulate the metabolic processes linked to the adequate preparation for gamete encounter in the oviduct. Our results suggest that SP should be maintained in AI to warrant miRNA regulation within the female genital tract for reproductive success.

Revisiting the Taxonomy of Cylapocoris Carvalho, 1954 (Hemiptera: Miridae: Cylapinae) with Descriptions of Five New Species and Morphology-Based Phylogenetic Analysis of the Genus.

This paper provides descriptions of five new species of the Neotropical genus Cylapocoris Carvalho, 1954 (C. bimaculatus n. sp., C. brooksi n. sp., C. carvalhoi n. sp., C. scutellatus n. sp., and C. simplexoides n. sp.). Cylapocoris and Cylapocoroides Carvalho, 1989 are redescribed and rediagnosed. Illustrations of male genitalia, scanning electron micrographs of selected structures of certain taxa, and an identification key to species are provided. Female genitalia are described and illustrated for the first time for Cylapocoris in nine out of 19 known species. A cladistic analysis of the genus, based on 62 morphological characters, is presented as a contribution to the understanding of relationships within Cylapocoris and its relationships with other groups of Cylapinae. The analysis comprises 16 ingroup species and 15 outgroup taxa. Both equal and implied weighting parsimony analyses were used in the phylogenetic reconstruction. We confirm the monophyly of Cylapocoris and its sister-group relationship with Cylapocoroides. Additionally, we identify subgroupings within Cylapocoris. Intertribal relationships within Cylapinae are briefly discussed.

Reconstructive and Aesthetic Surgeries on the Female Genitalia. Guideline of the DGGG, DGPRÄC, OEGGG and SGGG (S2k-Level, AWMF Registry No. 009/019, May 2022).

Aim This official guideline was coordinated and published by the German Society for Gynaecology and Obstetrics (DGGG), the German Society for Plastic, Reconstructive and Aesthetic Surgery (DGPRÄC), the Austrian Society for Gynaecology and Obstetrics (OEGGG), and the Swiss Society for Gynaecology and Obstetrics (SGGG). The guideline aims to provide a consensus-based overview of reconstructive and aesthetic surgeries on female genitalia based on an evaluation of the relevant literature. Methods This S2k-guideline was developed by representative members from different medical professions on behalf of the guidelines commission of the DGGG, DGPRÄC, OEGGG and SGGG using a structured consensus process. Recommendations Statements and recommendations on the epidemiology, aetiology, classification, symptoms, diagnosis, and treatment of acquired changes of the external genitalia are presented and special situations are discussed.

Outside the pattern: Evolution of the genital asymmetry in Saicinae (Hemiptera: Heteroptera: Reduviidae).

Despite genital structures in insects being consistently important as systematic and taxonomy evidence, within assassin bugs (Heteroptera, Reduviidae) at least, the male and female genitalic structures of several subfamilies are poorly or totally unknown. The genital structure is mostly symmetric within Saicinae genera, but male genital asymmetry has been recorded in Gallobelgicus, Polytoxus, and recently Pseudosaica. The subfamily has been considered as closely related to Emesinae and Visayanocorinae but this hypothesis has never been tested using a comprehensive taxa sampling, being a constraint to test morphological traits changes or exploring characters' evolution hypotheses. Here, we compiled a morphological data set of 170 characters that includes external morphological characters and genitalia of both sexes of Saicinae which was analyzed cladistically including 55 terminals, comprising 16 genera (64% of the generic diversity), 43 species of Saicinae and 12 outgroups. Saicinae was recovered as polyphyletic, Saicireta correntina is recovered as sister-species of Empicoris armatus + Collartida (Emesinae), Oncerotrachelus, Carayonia (Visayanocorinae), and the Clade Saicinae sensu stricto. Carayonia orientalis is recovered as sister-species of Saicinae sensu stricto. Ancestral state reconstruction of symmetry of the male genitalia shows an ancestor with symmetric male genitalia, two independent emergences of asymmetrical male genitalia within Saicinae sensu stricto, and the asymmetrical endosomal sclerites appearing before the other asymmetric traits.

Redescription of Periplanetaarabica (Bey-Bienko, 1938) (Blattodea, Blattidae), with a comparative analysis of three species of Periplaneta Burmeister, 1838 (sensu stricto).

The blattid cockroach Periplanetaarabica (Bey-Bienko, 1938) has been poorly understood since its original description. In this study, male and female (including nymph) of P.arabica are paired using DNA barcoding, and their morphological characters (including both external characteristics and genitalia) are described. A detailed comparative morphological study of this species and the closely related Periplanetaamericana (Linnaeus, 1758) and Periplanetalateralis Walker, 1868 was carried out to explore phylogenetically relevant characters.

Characterization of External Female Genitalia in Five Triatoma Laporte Species of South America (Hemiptera: Reduviidae: Triatominae).

Currently, there are 158 valid species of triatomines, all of which are potential vectors of Trypanosoma cruzi, the etiological agent of Chagas disease. The correct taxonomic identification of triatomines is essential since each species hos a different epidemiological importance. The aim of the study is to compare five species of South American Triatoma. Here we present a comparative study of terminal abdominal segments in females by scanning electron microscopy (SEM) of the species Triatoma delpontei, T. jurbergi, T. infestans var. melanosoma, T. platensis, and T. vandae. The results showed diagnostic characters for the studied species. The dorsal view featured more valuable characters, with seven informative characters. Similarities were observed among T. delpontei, T. infestans var. melanosoma, and T. platensis, and between T. jurbergi and T. vandae, correlating with previous studies. Thus, female genital characters proved to be reliable and useful in the diagnosis of the Triatoma species studied here; additional studies, along with other sets of behavioral, morphological, and molecular data, helped to reinforce the hypotheses found here.

Genital body image education in young adolescent girls: A proof of concept pilot study.

Our research team previously developed a brief educational video aimed at increasing adolescent girls' knowledge of the variation in cisgender female genital appearance and improving attitudes towards genital appearance. This video was efficacious with 16-18-year-old girls, but their feedback suggested that younger girls may gain greater benefit. Owing to the younger age group and sensitivity of the topic, we undertook a small pilot study, using a mixed methods approach (quantitative followed by qualitative study phase), to explore the understanding of 13-15-year-old girls of their genital anatomy and body image, and their impressions of the video. The sample (N = 6) showed, on average, low-to-moderate levels of genital anatomical knowledge and genital appearance satisfaction. In qualitative interviews, thematic analysis showed girls had received limited genital-related sexual education and had not considered genitals to be part of their concept of body image. However, after watching the video, they reported an appreciation of the diversity in genital appearance and encouraged use of the video in schools to prompt discussions about genital body image. There are broader implications of this research, namely, that the education of girls about the diversity in genital appearance could be important in improving their future gynaecological and sexual well-being.

Teaching vulval anatomy in the twenty-first century: The Australian experience.

Anatomy has often been regarded as an immutable discipline where everything that needs to be known is known. This article focuses on the teaching of vulval anatomy, the diversification of gender in contemporary society, and the increasing popularity of the Female Genital Cosmetic Surgery (FGCS) industry. The binary language and singular structural arrangements contained in lectures and chapters on "female genital anatomy" are nowadays rendered exclusive and incomplete. A series of 31 semi-structured interviews with Australian anatomy teachers identified barriers and facilitators for teaching vulval anatomy to contemporary student cohorts. Barriers included lack of connection to contemporary clinical practice, time and technical difficulty involved in regularly updating online presentations, the crowded curriculum, personal sensitivity to teaching vulval anatomy, and reluctance to introduce inclusive terminology. Facilitators included lived experience, regular use of social media, and institutional initiatives toward inclusivity including the support of queer colleagues.

Acquisition of novel muscles enabled protruding and retracting mechanisms of female penis in sex-role reversed cave insects.

Brazilian sex-role reversed cave insects (genus Neotrogla) have a striking structure called the gynosome (or female penis), which deeply penetrates male vagina-like genitalia during copulation to receive nutritious semen. However, the protruding and retracting mechanisms of the female penis, including their evolutionary origin, are poorly understood. By using micro-computed tomography (µCT), we compared the genital morphology and musculature between species with a gynosome and others lacking this structure. As a result, we discovered two groups of muscles related to the protrusion and retraction of gynosomes. These muscles were also observed in species with non-protrusible prepenis. This suggests that evolution of these muscles preceded the acquisition of the protruding function of the gynosome, originally having a putative stimulatory function to receive nutritious semen. This intermediate stage probably allowed for the reversal of genital functions.

"Normal vulva" based on the first national Labiagram design in adult Iranian women not seeking female genital cosmetic surgery: a pilot study.

Background: Several studies have been published to present normal values of female genitalia in different age and racial groups. Aim: The primary objective of our study was to measure the parameters of the external genitalia in adult Iranian women, record the data using the Labiagram system (the first national Labiagram design in Iran), and establish a preliminary database. Methods: A descriptive study was conducted from March 2022 to December 2022, involving 220 nonpregnant adult women who presented to the gynecology clinic. Women who met the inclusion criteria for the study underwent a comprehensive examination of the external genitalia. The data collected during the examinations were recorded in electronic files and the Labiagram system. Outcomes: The data showed the diversity of external genital parameters of nonpregnant adult Iranian women. Results: In this descriptive study, the mean ± SD age of the participants was 51.5 ± 13.44 years, ranging from 15 to 84 years. A total of 192 women (87.3%) had a history of vaginal delivery. There was no statistically significant difference observed in the average measurements of the vulva among the 4 age groups (P < .05). The Pearson correlation coefficient test indicated a statistically weak correlation between body mass index and perineum length (r = 0.174, P = .010). Additionally, a weak correlation was found between body mass index and the width of the labia minora at the left-lower point (r = 0.143, P = .030) and the right-middle point (r = 0.146, P = .031). Furthermore, the results demonstrated that women with a history of vaginal delivery had a significantly longer introitus (49.3 vs 44.3 mm, P = .037), longer labia majora (91.3 vs 87.3 mm, P = .046), and longer labia minora (56.8 vs 50.9 mm, P = .008) when compared with women without prior labor experience. Clinical Implications: The data will be used as a basis for future studies. Strengths and Limitations: The use of simple tools for the measuring, data recording, and digital drawing of female external genital anatomy, along with privacy protection, is one of the strengths of this research. The weakness is the small sample size, which is the reason for piloting the Labiagram chart for more extensive studies. Conclusion: Increasing age and the number of births had no statistically significant effect on the size of external genital parameters among Iranian women. Despite the considerable diversity in these parameters, it has not resulted in a significant demand among Iranian women for female cosmetic surgery.

Considerations on the Systematics of Neotropical Pierina, with the Description of Two New Species of Phulia Herrich-Schäffer from the Peruvian Andes (Lepidoptera: Pieridae, Pierinae, Pierini).

A comparative analysis of high-Andean Pierina was carried out, including a total of 25 species. Based on morphological evidence, with an emphasis on venation and genitalia and molecular data, using three genetic markers, we confirm the recent subjective synonymy of the generic names Tatochila Butler, 1870, Piercolias, Staudinger, 1894, Hypsochila Ureta, 1955, Infraphulia Field, 1958, Pierphulia Field, 1958, and Theochila Field, 1958 with Phulia Herrich-Schäffer, 1867. Two new species are described, namely Phulia stoddardi Pyrcz & Cerdeña n. sp., from the Andes of Central Peru, which occurs at an unusually high altitude of close to 5000 m a.s.l. in dry puna habitat, and Phulia phantasma Lamas, Willmott & Boyer n. sp., from dry montane forests in northern Peru and southern Ecuador. An overview of high-elevation butterflies is presented, with some discussion on adaptations to this environment.

Genomics reveals a new genus and species from a single female specimen (Lepidoptera: Hesperiidae: Hesperiinae: Hesperiini: Moncina).

New taxa in Hesperiidae (Lepidoptera: Papilionoidea) are traditionally proposed after inspection of male genitalia, which largely form the basis for Hesperiidae taxonomy. However, with genomic DNA sequencing, even a single female specimen can be placed in a phylogenetic context of existing classification and taxonomically assigned with confidence. Genomic sequencing of an unusually patterned Hesperiidae female from San Martin, Peru, characterized by pearly spots outlining an inverted heart pattern on the rust-colored ventral hindwing, reveals that it represents an undescribed genus and species named here as Gemmia buechei Brockmann and Grishin, new genus and new species.

Women's experience and perspectives toward genital cosmetic surgery in Erbil city/Iraq: a qualitative study.

BACKGROUND: Nowadays, Female Genital Cosmetic Surgery is quite prevalent, resulting in a wide range of medical and cultural implications. The majority of women who undergo this operation suffer from anxiety, depression, and other emotional symptoms. The present study was carried out in order to explore women's perspective on and experience of genital cosmetic surgery given their special context and cultural aspects. METHODS: The qualitative study applying content analysis examined the experiences of nine women who received genital cosmetic surgery in Erbil, Kurdistan-Iraq, between 2021 and 2022. Each of the semi-in-depth face-to-face interviews lasted between 40 and 60 min and was conducted at the physician's clinics. RESULTS: Semi-structured interviews led to emergence of two main themes, namely "husband satisfaction" and "self-confidence". Interpreting the participants' stories resulted in some relevant subthemes and meaning units like "ugly appearance", "anxiety related to husband undesirable intercourse", and "dyspareunia". Finally, the related conclusions of each theme were explored. CONCLUSION: As suggested by the study findings, female genital cosmetic surgery improves the women's body image and sexual function and the couples' sexual satisfaction, especially that of husbands. Because of the people's sociocultural aspects in Kurdistan region, their awareness of female sexual needs and marital relationship needs to be raised.

The Functional Morphology of the Bursa Copulatrix of a Butterfly That Does Not Digest Spermatophores (Leptophobiaaripa, Pieridae).

The bursa copulatrix of female Lepidoptera is a complex organ where crucial male-female reproductive interactions occur during and after copulation. The bursa copulatrix receives, stores, and digests the spermatophore and other substances transferred by the male during copulation, and is involved in changes in female receptivity, ovogenesis, and oviposition. Although females of the butterfly Leptophobia aripa do not digest the spermatophore, they possess a prominent signum. Since, in general, the function of the signum is considered to be the piercing or tearing of the spermatophore to initiate its digestion, its presence in L. aripa poses a conundrum. We undertook a microscopic study of the different components of the bursa copulatrix (ductus bursae and corpus bursae) and found structural differences that we interpreted in functional terms. We provide a detailed description of the signum and present experimental data regarding its effect on the spermatophore. Our observations led us to propose a novel hypothesis regarding the function of the signum.

Female Genital Variation Far Exceeds that of Male Genitalia: A Review of Comparative Anatomy of Clitoris and the Female Lower Reproductive Tract in Theria.

A review of the literature on the anatomy of the lower female genital tract in therian mammals reveals, contrary to the general perception, a large amount of inter-specific variation. Variation in female external genitalia is anatomically more radical than that in the male genitalia. It includes the absence of whole anatomical units, like the cervix in many Xenarthra, or the absence of the urogenital sinus (UGS), as well as the complete spatial separation of the external clitoral parts from the genital canal (either vagina or UGS). A preliminary phylogenetic analysis shows two patterns. Some morphs are unique to early branching clades, like the absence of the cervix, while others arose multiple times independently, like the flattening out or loss of the UGS, or the extreme elongation of the clitoris. Based on available information, the ancestral eutherian configuration of the external female genitalia included a cervix, a single vaginal segment, a tubular UGS, and an unperforated clitoris close to the entrance of the genital canal. The evidence for either bilobed or unitary glandes clitorides is ambivalent. Despite the wealth of information available, many gaps in knowledge remain and will require a community-wide effort to come to a more robust model of female genital evolutionary patterns.

Frequent origins of traumatic insemination involve convergent shifts in sperm and genital morphology.

Traumatic insemination is a mating behavior during which the (sperm) donor uses a traumatic intromittent organ to inject an ejaculate through the epidermis of the (sperm) recipient, thereby frequently circumventing the female genitalia. Traumatic insemination occurs widely across animals, but the frequency of its evolution, the intermediate stages via which it originates, and the morphological changes that such shifts involve remain poorly understood. Based on observations in 145 species of the free-living flatworm genus Macrostomum, we identify at least nine independent evolutionary origins of traumatic insemination from reciprocal copulation, but no clear indication of reversals. These origins involve convergent shifts in multivariate morphospace of male and female reproductive traits, suggesting that traumatic insemination has a canalizing effect on morphology. We also observed sperm in both the sperm receiving organ and within the body tissue of two species. These species had intermediate trait values indicating that traumatic insemination evolves through initial internal wounding during copulation. Finally, signatures of male-female coevolution of genitalia across the genus indicate that sexual selection and sexual conflict drive the evolution of traumatic insemination, because it allows donors to bypass postcopulatory control mechanisms of recipients.

New context, new content-Rethinking genital anatomy in textbooks.

It has been widely claimed that reductions in allocated teaching time and the widespread implementation of short-cut teaching methodologies have led to a shortfall in anatomy knowledge among graduating doctors. This decline in knowledge is evident in the failure of anatomy content to prepare graduates for contemporary clinical practice. The implications for postgraduate surgical training are addressed in the numerous extracurricular anatomy courses available to surgical candidates. This paper focuses on genital diversity and its relevance to non-surgical graduates, thus highlighting another potential impact of this knowledge shortfall on frontline clinic consultations. As the gender revolution and female genital cosmetic surgery industry flourish, nothing in contemporary anatomy textbooks addresses issues of diversification of female genitalia nor gives medical graduates a realistic view of what is normal regarding female genital appearance.

Three cryptic Anaplecta (Blattodea, Blattoidea, Anaplectidae) species revealed by female genitalia, plus seven new species from China.

Morphological characteristics, including male and female genitalia, combined with DNA barcodes were used to identify 470 Anaplecta specimens sampled from China. Ten Anaplecta species are new to science, including three cryptic species: A.paraomei Zhu & Che, sp. nov., A.condensa Zhu & Che, sp. nov., and A.longihamata Zhu & Che, sp. nov., which are distinguished mainly by their female genitalia. The other seven new species are as follows: A.bicruris Zhu & Che, sp. nov., A.spinosa Zhu & Che, sp. nov., A.ungulata Zhu & Che, sp. nov., A.anomala Zhu & Che, sp. nov., A.serrata Zhu & Che, sp. nov., A.bombycina Zhu & Che, sp. nov., and A.truncatula Zhu & Che, sp. nov. This study illustrates that differences in female genitalia can be used to distinguish among species of Anaplecta. The female genitalia of 19 Chinese Anaplecta species are described and illustrated in this paper.
