Two new species of the genus Melixanthus Suffrian, 1854 are described from China: M. menglaensis Duan, Wang & Zhou, sp. nov. from Yunnan (also in Vietnam, Tonkin) and M. similibimaculicollis Duan, Wang & Zhou, sp. nov. from Yunnan. Another species, M. rufiventris Pic, 1926, is reported for the first time in China. High-quality color images and line...

Many species of the gastropod genus Philine have been named from northeastern Asia but scanty descriptions based predominantly on shells make it difficult to determine which are valid. This, plus the sporadic anatomical and genetic information available for many of these species has led to what may be described as an un-integrated taxonomy. In this...

New Zealand’s surrounding deep waters have become known as a diversity hotspot for glass sponges ( Porifera : Hexactinellida ) in recent years, and description and collection efforts are continuing. Here we report on eight rossellids ( Hexasterophora : Lyssacinosida : Rossellidae ) collected during the 2017 RV Sonne cruise SO254 by ROV Kiel 6000 as...

A new species of the genus Bombyciella Draudt, 1950, Bombyciella linzhiensis sp. nov. , is described from the Linzhi (Nyingchi) Prefecture in southern Xizang (China), following a diagnostic comparison with B. talpa Draudt, 1950 and B. antra Saldaitis, Benedek, Behounek & Stüning, 2014. The adults and the male genitalia of the new and related specie...

Background The distribution pattern of Pholcus phungiformes species-group indicates that, in Jilin and Heilongjiang, China and North Korea, additional species diversity remains undiscovered. New information Pholcus maxian sp. nov., one new species of P. phungiformes species-group, is described, based on material collected from the borderline betwee...

The taxonomy within the genus Centrophorus has been controversial almost since its origin, raising uncertainties about the identification, the phylogenetic placement and the geographical distribution of several species. The partial nucleotide sequences of two mitochondrial DNA gene regions, the cytochrome c oxidase subunit I and the 16S ribosomal R...

Micro-computed tomography (micro-CT) is a high-resolution 3D-imaging technique which is now increasingly applied in biological studies focusing on taxonomy and functional morphology. The creation of virtual representations of specimens can increase availability of otherwise underexploited and inaccessible samples. The 3D model dataset can be also f...

Background Plant species diversity may be seriously threatened in ecotone zones under global climate change. Therefore, keeping updated inventories of indicator species seems to be a good strategy for monitoring wild areas located in these strips. The database comes from an inventory of climbers and vascular epiphytes conducted in the Cerro Ñielol ...
