Freshwater mussels belonging to the genus Cristaria Schumacher, 1817 (Bivalvia: Unionidae) are widespread from Mongolia to Indochina while the range of one species, C. plicata (Leach, 1814), covers two biogeographic subregions, i.e., East Asian (Amur River to Vietnam) and Sundaland (Mekong River basin). We present here a taxonomic revision of the nominal taxon Anodonta bellua Morelet, 1866 which was described from the Mekong (Lake Tonle-Sap, Cambodia) but is currently considered a synonym of C. plicata. We obtained molecular data for newly collected Cristaria representatives from the Mekong’s tributaries in Laos, which were found as a divergent species-level phylogenetic clade within the genus that is distant from C. plicata. Nevertheless, comparative morphological and morphometric studies did not reveal any significant differences between these two congeners. Our time-calibrated biogeographic modeling reveals that the split between Cristaria bellua (Mekong) and C. clessini (East Asia) probably occurred in the mid-Miocene (15.8 Ma) and may reflect an ancient stream capture between the Mekong Basin and East Asian rivers.

Six species of scorpion (Arachnida: Scorpiones) are documented from eighteen localities in seven different states within the Republic of the Sudan. Combining this new data with historical records in the Sudan Natural History Museum and the published literature enables the first provisional distribution maps for Sudanese scorpions. New state records could be added for three medically significant species: Androctonus amoreuxi (Audouin, 1826) from Khartoum, North Kordofan and North Darfur, Leiurus quinquestriatus (Ehrenberg, 1829) from Kassala, River Nile, White Nile and North Darfur, and Parabuthus abyssinicus (Pocock, 1901) from Kassala. Among the less venomous species, we offer new state records for Buthacus leptochelys (Ehrenberg, 1829) in White Nile State, for Compsobuthus werneri (Birula, 1908) in North Kordofan, White Nile and Kassala States and for Orthochirus olivaceus (Karsch, 1881) in River Nile, Northern and Kassala States. Further information about the taxonomy, distribution and toxicity of Sudanese scorpions is presented.

A new amphipod species belonging to the genus Gammarus is described from the Gökgöl Cave, Zonguldak Province, Türkiye. The newly-identified species is relatively small (13 mm) and is a member of the Gammarus pulex-group by the presence of numerous long setae along the posterior margins of pereopods 3 and 4. The specimens were sampled from a shallow pond located in the dark zone (about 1 km inside the entrance) of the cave. Minute eyes, setose (both peduncle and flagellar segments) second antenna, slightly swollen flagellar segments of the second antenna, setose pereopods 3 and 4 and relatively short endopod/exopod ratio of the third uropod are the character combination of the newly-identified species in addition to lacking body pigmentation. The molecular phylogeny, based on the concatenated dataset (28S+COI, 1495 bp) indicated that the new species was resolved from the other Gammarus species by high bootstrap (NJ: 100, ML: 100). In addition to Gammarus tumafsp. nov., mtDNA COI and nuclear DNA 28S gene data of Gammarus baysaliÖzbek et al., 2013 were recorded for the first time. The newly-identified species was well-differentiated from the genetically closest species, G. baysali, with genetic distance of 12.22% and 0.55% for the COI and 28S genes, respectively. Detailed descriptions and drawings of the extremities of the holotype male were given and the morphology of the newly-identified species is compared with its relatives.

Newly collected material from northern Namibia’s Otjihipa Mountains and west-central Angola allowed us to revisit the Afroedura bogerti Loveridge, 1944 group. The employment of additional gene markers, including nuclear markers, allowed us to identify two new species in the group and infer species boundaries and potential speciation events in Afroedura from southwestern Africa. The new Namibian material is recovered as a sister species to A. donveae, from which it differs mostly by the colour of the iris (copper versus black) and dorsal colouration. Material from the first elevational gradient of the escarpment in Benguela Province, Angola was found to be more closely related to A. bogerti than A. wulfhaackei. The differences between these two species are more subtle, although the new species exhibits higher mid-body scale rows (79.5 versus 74.8), different dorsal colouration and supranasal scales always in contact (versus 57% in contact).

Parglogenia cobourgensissp. nov., a new species of camaenid land snail is described from Cobourg Peninsula, Top End of the Northern Territory in Australia. This new species has a shell that is identical to the type species of the genus, Parglogenia pelodes, which also occurs in the Top End. However, both species clearly differ in their reproductive anatomy and are also well-differentiated in terms of mitochondrial phylogenetics. A single specimen of a Parglogenia species from Croker Island, West Arnhem Land, is hypothesized to represent a third species based on details of its reproductive anatomy. However, only a single historical specimen was available for study. We therefore refrain from formally naming this species because of the incomplete information at hand. Helix subgranosa Le Guillou, 1842, a nominal species previously placed in Parglogenia, is synonymized with Xanthomelon durvillii (Hombron & Jacquinot, 1841).

We describe a new species of New Guinea Worm-Eating Snake (Elapidae: Toxicocalamus) from a specimen in the reptile collection of the Papua New Guinea National Museum and Art Gallery. Toxicocalamus longhagensp. nov. can be easily distinguished from other species of this genus by the presence of paired subcaudals, a preocular scale unfused from the prefrontal scale, a prefrontal distinct from the internasal scale that contacts the supralabials, a single large posterior temporal and two postocular scales. The new taxon is currently known only from one specimen, which was collected from Mt. Hagen Town in Western Highlands Province, Papua New Guinea in 1967. The new species was originally identified as T. loriae, but the unique head scalation and postfrontal bone morphology revealed through micro-computed tomography scanning easily distinguish the new species from T. loriaesensu stricto. This is the first species of this genus described from Western Highlands Province.

The porcellanid genus Enosteoides Johnson, 1970, currently containing six species, was raised in the 1970s to contain aberrant Indo–West Pacific forms of the diverse and cosmopolitan genus Porcellana Lamarck, 1801. Here, we describe the most aberrant form as Enosteoides spinosussp. nov., from the northeast and northwest coasts of Australia and present results on phylogenetic reconstructions of the genus, based on an 1,870 bp alignment of concatenated DNA sequences of three mitochondrial and one nuclear gene. The new species is peculiarly spiny and has a higher morphological affinity to the type species of the genus, E. ornatus (Stimpson, 1858), than to the other congeneric species. Our molecular results indicate that Enosteoides is not monophyletic. The new species and E. ornatus are encompassed in a clade, which does not share immediate common ancestry with the clade containing the other species of Enosteoides. This clade is more closely related to species of Porcellana and Pisidia. Relatively large interspecific genetic distances between and within the two clades, as compared to distances estimated in American pairs of species on each side of the Panama Isthmus, suggest ancient divergence, probably followed by extinction events or low speciation rate. Relatively large intraspecific distances between Australian populations of the new species of Enosteoides from geographically distant locations suggest some level of phylogeographic structure.

Idiopyrgus is a relict genus of freshwater snails from Brazil traditionally classified in the family Pomatiopsidae. Herein, we use molecular data from newly acquired specimens to test that classification through Bayesian inference phylogenetic analysis. We conclude that Idiopyrgus belongs in the Gondwanan family Tomichiidae, together with the African genus Tomichia and the Australian genus Coxiella. Furthermore, we reassess currently synonymized genus- and species-level names in Idiopyrgus. The genera Hydracme and Aquidauania are considered synonymous with Idiopyrgus. The species I. brasiliensis and I. pilsbryi are restored as accepted species; I. walkeri is considered a taxon inquirendum. Two new species from caves in Bahia state are described herein: Idiopyrgus adamanteussp. nov. and Idiopyrgus minorsp. nov.
