Five species of Merodontina have been recorded from China to date: M. jianfenglingensis Hua, M. nigripes Shi, M. obliquata Shi, M. rectidensa Shi, and M. rufirostra Shi. Since first described between 1987 and 1991, these species have not been redescribed or reported. Although 16 species were described in Merodontina, no molecular data have been available for this genus. We examined type specimens of all five previously described species from China, provided high-resolution images and redescriptions. We synonymized M. rufirostra Shi under M. rectidensa Shi, M. bellicosa Scarbrough and Costantino and M. silvatica Haupt and Azuma under M. obliquata Shi, and M. vietnamensis Tomasovic and Bartolozzi under M. jianfenglingensis Hua. The previously proposed name M. abligueodentia Shi, 1992 is formalized as a nomen nudum under M. obliquata Shi. We obtained DNA barcodes from multiple populations of M. jianfenglingensis and the widely distributed M. obliquata. Genetic analyses revealed distinct barcoding gaps, with interspecific distance of 15.7 %–16.8 % versus intraspecific distance of 0 %–2.6 %. An updated key to males of the Chinese species of Merodontina and a revised world catalogue are provided.

During cranial development, ossification centers appear sequentially, either through chondral or membranous processes. Birth represents a critical transition to life into a new environment, involving a progressive reduction in maternal dependence and exhibiting varying degrees of neonatal maturity, from altricial to precocial. Twenty-five prenatal and fourteen postnatal specimens of Dasypus hybridus (Xenarthra, Mammalia) were processed using an enzymatic clearing and double-staining technique, with Alcian Blue to identify cartilage and Alizarin Red to reveal ossifications. Using Total Cranial Length (TCL) as a proxy, eight prenatal cranial ontogenetic stages and three postnatal stages, spanning from two to thirty days of age, were identified. The first ossification centers to appear are those of the facial region, followed by the vault and the base of the skull, with the ethmoid complex being the last to ossify. The cranial, postcranial, and integumentary skeletal maturity data presented here suggest that D. hybridus is relatively precocial compared to other armadillos, such as Chaetophractus villosus and Chaetophractus vellerosus, which are positioned further along the altricial spectrum”

Middle Eastern Blind Mole Rats (BMRs), subgenus Nannospalax, are a complex subgenus consisting of nine species described by traditional methods, consist of seven chromosomal races represented by seven different diploid chromosome numbers (2n = 48, 52, 53, 54, 56, 58, and 60), and numerous cryptic species. However, Middle East BMRs are currently referred to under a single species name (Nannospalax ehrenbergi) due to unresolved taxonomic issues. However, Middle East BMR populations in the Anatolian Peninsula, a global hotspot of diversity of Nannospalax, have not been extensively investigated in previous studies. In this study, all chromosome races and almost all populations of Middle East BMRs were examined comparatively for the first time. With an integrative taxonomic perspective, particularly based on morphology, karyology, and molecular genetics (cytb and COI fragments), we have revealed new findings on the taxonomic status and distribution of Middle East BMR species. We excluded Nannospalax ehrenbergi s. str. from the Anatolian Peninsula, and the name Nannospalax ehrenbergi was attributed to the populations immediately surrounding the type locality and to the Israeli and Palestinian populations. Nannospalax intermedius and Nannospalax ceyhanus, identified to the Southeastern Anatolian BMR populations and considered synonyms of Nannospalax ehrenbergi s. str. in previous studies, are recognized as valid biological species independent from Nannospalax ehrenbergi. In addition to these species, three new cryptic species were identified for the Anatolian Peninsula BMR populations, based primarily on mitochondrial DNA sequence differences: Nannospalaxkaryominor sp. nov. from Hatay (Yayladağ); Nannospalaxgarzanensis sp. nov., from Diyarbakır, Siirt, and Batman; and Nannospalaxcolaki sp. nov. from Gaziantep and Kilis. In Israel, Nannospalax golani-Nannospalax galili and Nannospalax carmeli-Nannospalax judaei were determined to be sister taxa. Nannospalaxehrenbergi was considered a superspecies representing the four species in Israel and one species (Nannospalax aegyptiacus) in Egypt. In summary, our study significantly advances our understanding of Middle East BMRs, increasing the number of currently recognized taxa in the subgenus Nannospalax from one (Nannospalax ehrenbergi) to nine species, including Israeli and Egyptian species.

Stick insects are herbivorous animals found in tropical, subtropical or temperate regions worldwide. Their digestive system is typically tubular, divided into regions with subregions that can vary among species. Arumatia dubia (Phasmatodea: Diapheromeridae) is a species that has undergone several taxonomic changes based on recent studies of external morphology, but morpho-histological analyses of internal organs, such as the digestive system, can contribute with identification to these and other Phasmatodea species. This study aimed to describe the digestive system of third instar A. dubia nymphs, using histochemical techniques and scanning electron microscopy. The digestive system of A. dubia consists of three regions and their subregions: foregut (esophagus and crop), midgut (anterior and posterior), and hindgut (ileum and rectum). The foregut has a simple epithelium covered by the tunica intima, and externally, surrounded by muscle fibers. The midgut features columnar cells with a brush border and regenerative cells. Malpighian tubules originate in the ileum (hindgut) and have an excretory function. This study provides detailed morpho-histological data on third instar A. dubia gut, contributing important information about the morphology and histology of the digestive system of this species.

Bionoblatta Rehn, 1940 is allocated in the poorly known and intriguing Brachycolini, a Neotropical tribe with eight genera and 44 blaberid species. This outstanding genus of cockroaches encompasses mostly montane and brachypterous species, all endemic to Brazil. Nevertheless, they are moderate sized and noticeable species due to coloration, pronotum shape, and callosities on the abdomen, all taxonomic knowledge is based on a small number of males. In this study, we revisit the taxonomy of Bionoblatta, based on a comparative morphological analysis, providing a comprehensive overview of the genus. Our results support Bionoblatta as a taxonomically distinguishable genus comprising six species with a distribution range exclusively in southeastern Brazil. Bionoblatta marcellisp. nov. is herein introduced (holotype male deposited in DZUP: Brazil, Minas Gerais State, Catas Altas) based on males, females, and nymphs. A diagnosis, notes on morphology and natural history, photographs of type and non-type specimens, a distribution map, and an identification key are provided for the species. We hope this study inspires further investigations into this fascinating group of cockroaches, deepening our understanding of their evolutionary history. Future research could explore their phylogeny and biogeography, habitat and social behavior, as well as intra- and interspecific morphological variations.

Eggshells display stable patterns and are able to provide solid basis for insect identification. Notodontidae are usually considered as significant pests for their larvae causing serious damage during outbreaks, underscoring the importance of early and accurate identification. In this study, nine notodontid eggshells from eight genera were compared using cold field emission scanning electron microscopy, in order to discover detailed evidence for the egg identifications. The eggshells exhibit morphological differences on the micropyle area, chorion sculpture, aeropyle density, and polygonal wall details. Notably, the eggshell ornamentations are different between the congeneric species E. splendida and E. cristata, highlighting the potential of eggshell morphology to enhance taxonomic research.

In this study, we obtained the complete mitogenome of Lutjanus fulvus from a specimen collected in Pakistani waters (63.95°E, 25.30°N) by utilizing high-throughput sequencing technology, then we characterized it and downloaded the complete mitogenomes of closely related species to constructed phylogenetic trees based on 13 protein-coding genes (PCGs) using Bayesian Inference (BI) methods. The complete mitogenome of L. fulvus is a typical closed circular double-stranded DNA molecule, was 16 493 bp in length, with a relatively low G content (16.2 %) and a high AT pronounced bias (52.8 %). The genome comprises 37 genes: 22 tRNAs, two rRNAs, 13 PCGs, and one putative control region (D-loop). Among the 13 PCGs, four types of stop codons (TAA, TAG, AGA, T--) are observed, and all genes, except for COX1, which starts with GTG, begin with the ATG start codon. The BI trees exhibited consistent topologies, indicating close relationships with Lutjanus vitta and Lutjanus ophuysenii. This study provides valuable genomic insights into the mitogenome of L. fulvus, enhancing our understanding of phylogenetic relationships within the Lutjanidae family and offering a fundamental reference for further exploration of mitogenomes in the Lutjanus genus. Furthermore, these data contribute new molecular evidence and theoretical foundations for the classification, genetic diversity studies, and the conservation and management of L. fulvus.

The Peruvian species of Psectrascelis Solier, 1836 (Pimeliinae: Nycteliini) are revised and a phylogenetic analysis is conducted on the basis of characters of external morphology plus the male and female genitalia. Also, based on a barcode region of the COI gene, the genetic distance of some species collected specifically for this study is calculated. Based on morphology, Peruvian species of Psectrascelis form a monophyletic group named here laevigata group and constitute a well-characterized species-group inside the genus. This group comprises 11 species/subspecies, out of which six are described as new: Psectrascelis sacratus Giraldo & Flores sp. nov., Psectrascelis claudiavelizae Giraldo & Flores sp. nov., Psectrascelis laevigata huayruro Giraldo & Flores ssp. nov., Psectrascelis yanatulti Giraldo & Flores sp. nov., Psectrascelis chankas Giraldo & Flores sp. nov., and Psectrascelis altiplanicus Giraldo & Flores sp. nov. Other valid species of the group are: Psectrascelis politicollis Fairmaire, 1876, P. laevigata (Erichson, 1834), Psectrascelis marginipennis Kulzer, 1954, Psectrascelis subplanata Peña, 1994, and Psectrascelis rufipes Kulzer, 1954 stat. n. Psectrascelis escobari Peña, 1985 is synonymized under P. laevigata (Erichson, 1834), P. laevigata rufipes Kulzer, 1954 is raised to species status and a neotype is designated for Nyctelia laevigata Erichson, 1834. Psectrascelis aequalis Fairmaire, 1876 and Psectrascelis intricaticollis Fairmaire, 1876 are excluded from the Peruvian fauna. This article includes morphological descriptions or redescriptions of each of the 11 species/subspecies including features of male genitalia, complemented by an identification key and distribution maps. The external morphology and male/female genitalia are discussed to propose characters that may be informative for phylogenetic analysis. Also based on the distributional patterns a biogeographical scenario is suggested.

The family Lepetidae Gray, 1850 is a small group of limpets widely distributed from tidal zone to abyssal. The monophyly of the family is supported by both morphological traits and molecular phylogenetic analyses, but phylogenetic relationships within the family remain unsolved. The current phylogenetic analyses based on four gene markers (COI, 16S, 12S and H3) revealed a highly supported clade including the Northwestern Pacific lepetids. Sagamilepeta sagamiensis is a sister species to Lepeta caeca and should be synonymized with the genus Lepeta on the basis of morphological traits and genetic distances. Cryptobranchia is a separate genus which differs from Lepeta in both radular morphology and phylogenetic position. In addition, the analyses revealed the second undescribed species of the genus Limalepeta which has amphiboreal distribution. Keys to the identification of the Northwestern Pacific Lepetidae are given based on the shell and radula morphology.
