The Bonaspeiini tribe’s validity is a subject of ongoing debate.

Hypotheses based on previous DNA research have suggested the existence of an unnamed species, closely related to Chiasmocleis haddadi, in French Guiana and the Amapa state of Brazil. A unified analysis of genetic, morphological, and acoustic characteristics confirms that these populations are uniquely distinct from C. haddadi and all other presently recognized congeneric species. This work describes and names this new species, and amends the definition of C. haddadi, because the original specimen set and diagnosis incorporated specimens of this new species. Geographically situated eastward of its sister species C. haddadi, the new species exhibits a larger body, a proportionally smaller eye, and a distinct dorsal color pattern, which sets it apart. The new species is thought to reproduce in leaf litter, with its tadpoles undergoing endotrophic development, whilst the co-occurring C. haddadi and C. hudsoni lay their clutches within nearby leaf litter, next to the standing water of temporary ponds, for the exotrophic tadpoles’ completion of development. The easternmost Guiana Shield now boasts another new species, joining the already substantial list of endemic animals, a region singled out as a unique bioregion within Amazonia by prior investigations.

Two recently discovered genera, from the Chimalapas region of eastern Oaxaca and Zongolica, Veracruz, Mexico, are being detailed. Due to the presence of a caudomarginal projection, ending in an ornate terminal plate, *Mokayathelphusa angelsotoi*, a new species from Oaxaca, is classified in the Pseudothelphusinae subfamily. In recognition of A. zongolicae (Alvarez, Villalobos & Moreno, 2012), a new combination, the genus Alvarezius is now formalized. While previously categorized within the Pseudothelphusa genus, a recent molecular phylogenetic analysis employing partial sequences from COI, 16S, and H3 genes suggests that this species stands as a sister lineage to Tehuana and is no longer classified within Pseudothelphusa. The new genus’s establishment is reinforced by these results, alongside a thorough morphological analysis.

Andinodarnis, a recently identified genus, has been characterized. Providing this JSON schema: list[sentence] The classification (Darninae Darnini) is suggested by recent treehopper findings in the Northern Andes. The newly recognized genus comprises two species, Andinodarnis pectoralis (Stal, 1869) comb. This JSON schema contains a compilation of sentences. Tomogonia pectoralis Stal, from the year 1869, and a new species, Andinodarnis atromeris. Sentences, listed, are desired in JSON schema format. iap signal PNN Tatama, a protected area in the Cordillera Occidental mountains of Colombia, deserves attention. The identification keys, annotated diagnoses, life history records, and distribution maps for both species are available, along with illustrations and newly recorded distribution data originating from Ecuador.

In the current study, we describe and illustrate two new species, Pseudosmittia luna and Pseudosmittia valida, which are derived from observations of adult male specimens collected from the West Bengal plains of India. The Pseudosmittia luna species possesses a DNA barcode. The species’ genetic profile, when scrutinized in relation to a selection of homologous sequences from the NCBI GenBank database, strongly suggests a close relationship with an unidentified species characterized by accession number MG301870. As a complement to our resources, we have provided a key for the adult male Oriental species of the genus.

The larval morphology, life cycle, and nutritional value of Lepidostoma abruptum Banks 1931 are the focus of this detailed description and analysis. The larval case’s cross-section is rectangular, fashioned from a collection of rectangular leaf segments. The larval morphology of Lepidostoma abruptum is comparable to the morphological traits found in other Lepidostoma species. Descriptions from various countries and continents have been detailed. A study of the head capsule widths in 74 specimens, through measurement and charting, aimed to categorize the larval instars. The life cycle of this species is not tied to any specific season. Moreover, the samples’ moisture content (6887%) and dry weight nutritional profiles were measured, showing protein at 4908%, total fat at 2713%, total dietary fiber at 59%, omega-3 at 015%, omega-6 at 604%, and omega-9 at 117%. The larvae of this species thrive in small debris pools, characterized by a dominance of leaf litter and small branches.

A revision of the taxonomy is necessary for the *Hipposideros larvatus* species complex, which encompasses a wide range of morphologically similar forms. We detail the phylogenetic results of an analysis, encompassing members of this species complex, using two mitochondrial (CytB and COI) and seven nuclear (ABHD11, ACOX2, COPS, RAG2, ROGDI2, SORBS2, and THY) genes, alongside a morphometric analysis. Although morphological data reveals certain diversity, it is insufficient for accurately determining taxonomic boundaries, sometimes conflicting with genetic classifications. Mitochondrial genetic studies provide evidence supporting the paraphyletic nature of the H. larvatus species complex, exhibiting H. armiger’s nested placement within it. The nuclear data yielded a monophyletic clade, comprising all the lineages of H. larvatus sensu lato. Revealed within Southeast Asia, apparently, were four different species-level clades. Northern Myanmar, southern China (including Hainan), and northern Vietnam are known to harbor this species, while a segment of its distribution extends to the coastal regions of central Vietnam, specifically the Cham Islands. Allen’s published work unequivocally declares H. poutensis as the legitimate taxonomic name for this group. The second clade, encompassing populations on the Malay Peninsula and the Sunda Islands, is identified as *H. larvatus sensu stricto*. Only in southern Myanmar was the third taxon discovered. In southern and central Indochina, the fourth taxon can be found. The representatives of this species exhibited no discernible connection to any Myanmar-based forms, casting doubt on its prior classification alongside H. grandis. Because the third and fourth taxa are now indecipherably linked to any specific named form, they are conventionally denoted as H. cf. Grandis 1 and 2, a testament to nature’s magnificence.

A phylogenetic study of the Mirinae subfamily was conducted, drawing upon 89 external and genitalic morphological traits. Employing a parsimony analysis, the phylogenetic relationships of 46 species, distributed among 30 genera, were reconstructed using both unweighted (EW) and implied weighted (IW) characters. A monophyletic cluster of eight genera—Stenodema, Polymerus, Orthops, Lygus, Phytocoris, Adelphocoris, Grypocoris, and Brachycoleus—was identified, in conjunction with the ACM (Adelphocoris, Creontiades, Megacoelum) complex, the Closterotomus complex, and the Lygus complex. The morphological evidence supporting the phylogenetic relationships is analyzed and discussed. A determination of the taxonomic standing of Pseudomegacoelum irbilanum was carried out. For clarity on characteristic features, scanning electron micrographs, depictions of genitalic structures, and digital images of the habitus of chosen species are presented. In this investigation, the phylogenetic relationships of plant bugs in Iran are analyzed for the first time.

The class Homoscleromorpha, presently composed of only one order and two families, has undergone significant shifts in its systematics in the last twenty years. Through the integration of morphological, cytological, and molecular (CO1) data, we have characterized three new aspiculate Homoscleromorpha species, including two species belonging to the Plakinidae and one from the Oscarellidae. In the dark, submarine caverns of the Lesser Antilles (Caribbean Sea), three sponges reside. Aspiculortis gen., a taxonomic categorization, merits additional details to be completely understood. Nov. is a part of a clade, which also encompasses spiculate Plakortis species. The genus Aspiculortis, specifically the garifuna subspecies, is a newly identified species. A JSON schema containing a list of sentences is required. This schema provides a list of sentences, as requested. November is notable for its original smooth pseudo-cribriform surface, a network of translucent canals ending in prominent oscula, and the concentration of one kind of vacuolar cell within its ectosome. Specifically, *Aspiculophora papillata* is a distinguished species. A distinctive characteristic of November is a papillate surface, a morphological trait never before observed in Homoscleromorpha, accompanied by a widespread random distribution of vacuolar cells within the mesohyl. Oscarella minka, a unique species, is described in this research paper. November’s surface is smooth, featuring two distinct types of vacuolar cells; one predominantly located within the ectosome, and the other distributed randomly, containing unique inclusions. Newly identified Homoscleromorpha specimens, three in total, exhibit a plentiful microbial community residing within their mesohyl. Following the completion of this study, the sponge class’s non-skeletal representatives consist of four species of Plakinidae from three different genera, along with all described Oscarellidae. The theorized absence of a skeleton underscores the need for a more comprehensive cytological investigation of Plakinidae examples.
