“…Schilthuizen (2004) mentioned a possible species from the Crocker Range that he could not class with either of the previously-described species and Schilthuizen and Liew (2008) reported another undescribed species from Long Pa Sia. Schilthuizen et al (2018) then described a lowland species, M. exquadratus , while also showing, in a phylogenetic analysis of COI DNA-barcodes, that at least five more undescribed species were likely to be present in northern Borneo. Vermeulen and Liew (2022) then described the species previously reported by Schilthuizen (2004) as M. basifixus Vermeulen & Liew, 2022 and another species from lower montane forest of the Crocker Range as M. convolutus Vermeulen & Liew, 2022.…”

During citizen-science expeditions to the Ulu Temburong National Park, Brunei, several individuals were collected of a semi-slug species of the genus Microparmarion that, based on morphology and in-the-field DNA-barcoding, was found to be an undescribed species. In this paper, we describe Microparmarion sallehi Wu, Ezzwan & Hamdani, n. sp., after field centre supervisor Md Salleh Abdullah Bat. We provide details on the external and internal reproductive morphology, the shell and the ecology of the type locality, as well as a diagnosis comparing it with related species. DNA barcodes were generated for five individuals and used for a phylogenetic reconstruction. Microparmarion sallehi sp. n. and M. exquadratus Schilthuizen et al., 2019 so far are the only Bornean species of the genus that live in lowland forest; other species are found in montane forests.

“…To date, although South Asian taxa have been included in molecular phylogenetic analyses of deep-level pulmonate relationships (e.g., Wade et al 2001Wade et al , 2006Herbert & Mitchell 2009;Ramirez et al 2012), studies focussing on the molecular systematics and diversification of South Asian helicarionoideans have yet to be carried out. With the exception of the substantial work done on Australian helicarionids (e.g., Hyman et al 2007Hyman et al , 2017Hyman & Ponder 2010;Hyman & Köhler 2019), this reflects the general scarcity of such studies globally (but see Schilthuizen et al 2019;Pholyotha et al 2020a).…”

We here describe a new Indian helicarionoidean genus, Varadia Bhosale & Raheem gen. nov., containing the single species Varadia amboliensis Bhosale, Thackeray, Muley & Raheem gen. et sp. nov. This new semi-slug is endemic to the northern and central Western Ghats and is primarily a forest-living species. We describe and figure the shell, reproductive system, radula, spermatophore and external morphology of this new species, and detail its known distribution. We explore its relationships to other helicarionoideans using phylogenetic analyses of DNA sequence data for part of the ribosomal RNA gene cluster and discuss the morphology of the new genus in relation to other, primarily South Indian, helicarionoidean taxa. Based on characters of the reproductive system, particularly the male genitalia and the gametolytic sac, we provisionally place Varadia gen. nov. in the Macrochlamydinae (Ariophantidae). This is consistent with the results of our molecular phylogenetic analyses. The combination of large size, broad, densely tuberculated shell lobes and a shell with ca 4 whorls and a disproportionately large body whorl makes V. amboliensis gen. et sp. nov. unique among the helicarionoidean taxa of the Western Ghats. The new semi-slug is also highly distinctive in the morphology of its male genitalia.

“…We expect this concept may (i) improve the public appreciation for taxonomy and (ii) yield valid taxonomic output (e.g. Schilthuizen et al 2018). Field courses practising this concept start off with several days of coursework at a field centre, during which participants are trained by taxonomic experts in field and lab methodologies for species discovery and identification (including DNA-barcoding using a portable nanopore set-up amongst others; Menegon et al 2017).…”

BackgroundClavicornaltica is a genus of very small flea beetles living in the leaf litter layer of Asian forests, easily sampled with Winkler extraction. The genus is presumably very rich in species, but their taxonomy is hampered by their small size and morphological uniformity.New informationOn a ‘taxon expedition’-style field course at Kuala Belalong Field Studies Centre in Brunei Darussalam (Borneo), a new species, Clavicornaltica belalongensis n. sp., was discovered and taxonomically treated by the course participants. We also present the first DNA barcodes for the genus.
