NEW INFORMATION: The genus Aetius O. Pickard-Cambridge, 1897 is reported for the first time in China (Yunnan Province) and includes three species: one new species and two newly-recorded species. One new species is described, based on both sexes: A.maculatus sp. n. Additionally, A.bicuspidatus Yamasaki, 2020 and A.nocturnus Deeleman-Reinhold, 2001, are newly recorded from China, with photographs of habitus and genitalia being provided.
NEW INFORMATION: The genus Serendib Deeleman-Reinhold, 2001 is reviewed. A new species, S.hispida sp. n. (male and female), representing the first record of genus Serendib from Malaysia, is described. Descriptions and illustrations of the females of S.volans (Malaysia) and S.suthepica (China) are also provided. The latter represents the first record of the genus in China.
NEW INFORMATION: This study provides a description of the east coast shore of Peninsular Malaysia, specifically in Johor coast in 2015-2016. The spatial and temporal distribution and abundance of a total of 41 taxa were assessed at four monsoon-exposed locations. These data provide a comprehensive baseline against disturbance and recolonisation of macroalgal community can be effectively and objectively evaluated.
New information: Eritingis and E. recentis are recorded from Japan and Thailand for the first time.
New information: On a field course at Kuala Belalong Field Studies Centre in Brunei Darussalam (Borneo), a new caenogastropod species, belonging to the genus Craspedotropis, was discovered by the course participants. The participants decided to name the species Craspedotropis gretathunbergae n. sp., in honour of the climate change activist Greta Thunberg, as caenogastropod land snails, such as this species, are likely to suffer because of climate change.
New information: On 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.
New information: During the first-ever taxon expedition, in Maliau Basin Studies Centre, Sabah, Malaysian Borneo, the participants sampled leaf litter beetles from lowland dipterocarp forest using the Winkler apparatus. The collected material proved to contain at least three undescribed species of small-bodied (ca. 1 mm long) hemispherical litter-dwelling Coleoptera. As part of the field course work, taxonomic descriptions were prepared for the chrysomelid Clavicornaltica sabahensis sp. n. and the leiodids Colenisia chungi sp. n. and Dermatohomoeus maliauensis sp. n.
New information: One species is a new record for China (Dischistodus pseudochrysopoecilus) and 23 species are newly found in the Xisha Islands.
