These discoveries significantly broaden the morphological concept of the genus, necessitating an amended diagnosis to accommodate unique characters such as the presence of sternal cones on both rings 5 and 6 in . and a highly characteristic, anchor-shaped (trifid) solenophore tip in . . shows distinct troglomorphic traits, including a small and pallid body, suggesting adaptations to a strictly subterranean existence. In addition, (Attems, 1953), a poorly known congener from northern Vietnam, is redescribed and illustrated based on type material from the Naturhistorisches Museum Wien, Austria. An updated identification key to all nine accepted species of the genus is provided, with a distribution map.

This record represents both the deepest occurrence of Sabellariidae in Japan and the first record of the genus from the region. . dwells in a tube made of small sand particles and foraminiferans, which is attached to the spines of a cidarid sea urchin. The new species is characterized by having 22-30 pairs of outer paleae arranged in a spiral, outer paleae with acute tips and compact thecae, one or two inner paleae in each row, 8-13 opercular papillae on each side, five pairs of nuchal hooks with curved tips, a pair of slender ventral lobes on the first chaetiger, a single pair of conical papillae on the second chaetiger, bilobed notopodia in the middle to posterior abdomen, and abdominal uncini bearing three rows of teeth. A phylogenetic analysis, which included the new species and the newly sequenced and and was based on sequences of four gene fragments (COI, 16S, 18S, and 28S), was conducted. The new species was nested within the fully supported clade and recovered as the sister taxon to , whereas support values for phylogenetic relationships among sabellariid species were generally low.

Despite its distinctive morphology, the genus remains poorly represented in collections and its taxonomy unresolved. During recent field surveys in southeastern Cameroon, ten specimens were collected from the Northwestern Congolian Lowland Forest, eight from Lobéké National Park (LNP) and two from the Dja Biosphere Reserve (DBR). Morphometric and molecular analyses assigned these specimens to eight species, including representatives of three species groups (, , and ). One species, , is recorded for the first time from Cameroon and two are described herein as new to science, . and . These findings increase the total number of recognised species to 15 and confirm that , as previously understood, represents a species complex, revealing further cryptic diversity within the genus. By combining taxonomic, ecological, and distributional data, our results indicate that most members of the genus tolerate moderate habitat degradation and that all 11 species recorded from Cameroon occur within or adjacent to at least one protected area. This study provides the first integrated taxonomic assessment of in Cameroon, refines species distributions, and contributes additional ecological data for three species (, , and ) currently listed as Data Deficient on the IUCN Red List. Our findings underscore the importance of continued sampling in the Guineo-Congolian region to better inform the conservation of Africa's forest-dependent bats.

The new species is diagnosed from its congeners by the following combination of characters: female SVL 32.5 mm and male SVL 18.3 mm, dorsolateral folds formed by rows of subconical tubercles, strongly areolate ventral skin, two distinct rows of forearm tubercles, one along the ventrolateral margin and a second along the externolateral margin of the forearm, and a prominent yellow groin blotch in the female holotype. The species belongs to the group, part of the subgenus, and is closely related to , , and . Currently, the species is known only from its type locality, where it inhabits low montane evergreen forests at elevations of 1,655-1,830 m. Additionally, we discuss the use of the term "ulnar tubercles" in , noting that it may refer to tubercles occupying different positions on the forearm.

The genus , one of the most diverse and taxonomically challenging groups of Collembola, has long been affected by incomplete historical descriptions. Recent advances in macrochaetotaxy-based methodologies, particularly those developed by Jordana and collaborators, have significantly improved species diagnoses and clarified the taxonomy of the tribe Entomobryini. In addition, recent global revisions further emphasize the need for standardized morphological terminology. The genus , comprising 44 species with a worldwide distribution and characterized by distinctive scales, is here supplemented by the description of a new species. These findings contribute to a more robust understanding of the diversity of Palaearctic Entomobryidae.

This study combines morphological and molecular phylogenetic approaches to describe a new genus and species within the Squamapicidae family that possesses the characteristic of a highly ornamented protoconch: H. Zheng, H.-Q. Xiang, L.-J. Zhang & X.-P. Wu, . Through the observation and cultivation of three species of freshwater snails with highly ornamented protoconchs from Yunnan, it was found that the formation and function of the highly ornamented protoconch vary across different species. The role of the posterior canal is discussed by examining the habitat of .
