1. Two new species of parastenocaris (Copepoda, Harpacticoida) from a hyporheic zone and overview of the present knowledge on Stygobiotic Copepoda in Vietnam : historical overview and new dataNgoc-Son Tran, Mau Trinh-Dang, Anton Brancelj, 2021, original scientific article Abstract: The number of freshwater species belonging to the genus Parastenocaris reported from ten countries of Southeast Asia is quite limited. Only two species have been reported so far from freshwater habitats there, compared to over 290 described species of the family Parastenocarididae worldwide. During the first study of the hyporheic zone of two small rivers in central Vietnam, two new species of the family Parastenocarididae were collected, Parastenocaris sontraensis sp. nov. and Parastencaris vugiaensis sp. nov. Both were collected from the gravel bar along the rivers (Suoi Da and Vu Gia river) using the Karaman–Chappuis method. Both the new species belong to the brevipes group of the genus Parastenocaris Kessler, 1913 sensu Lang (1948), and Reid (1995). Parastenocaris sontraensis sp. nov. is similar to P. hinumaensis Kikuchi, 1970 and Parastenocaris jane Karanovic, 2006 in the brevipes-group. Parastenocaris sontraensis sp. nov. differs from both Parastenocaris species by (i) Exp P3 with three segments in the male, (ii) caudal rami with seven setae, and (iii) caudal rami about 2.4 times as long as wide. Parastencaris vugiaensis sp. nov. can be distinguished from its congeners by the unique combination of the following characters: (i) the elliptical shape of caudal rami, (ii) apical seta (V) with bulbous base, and (iii) anal operculum extends beyond the end of anal somite. Until now, 14 stygobiotic species of Copepoda have been recorded in Vietnam (including two new species in this paper), which is relatively few compared with nearby Thailand with 25 species. Short comments on other stygobiotic Copepoda from Vietnam are added.

2. Two new species of Elaphoidella (Copepoda, Harpacticoida) from subterranean waters in Northeast Thailand, with a record of a gynandromorphic specimen and an up-to-date key to Elaphoidella species from Southeast AsiaChaichat Boonyanusith, Anton Brancelj, La-orsri Sanoamuang, 2024, original scientific article Abstract: Two new species of copepods of the genus Elaphoidella Chappuis, 1929 were discovered in a cave and a spring in northeastern Thailand. The first species, E. phuphamanensis sp. nov., belongs to species-group VII sensu Lang. It is most similar to E. turgisetosa Petkovski, 1980 in the armament of the male third exopod of the fourth swimming leg and the shape and armament of the fifth swimming leg in both sexes. However, it is easily distinguished from other congeners by the segmentation of the first swimming leg, the endopod of the fourth swimming leg, and the armature of the third exopod of swimming legs 2–4 in both sexes. The second species, E. propecabezasi sp. nov., is located in species-group I sensu Lang, where the male does not have a transformed seta on the third exopod of the fourth swimming leg and the female fifth swimming leg has four baseoendopodal robust setae, unequal in length. It is most similar to E. cabezasi Petkovski, 1982 and E. paraaffinis Watiroyram, Sanoamuang and Brancelj, 2017 in having the same armature formula as endopods 1–2 of female swimming legs 1–4. However, the ornamentation of the anal operculum, the shape of the caudal ramus, and the armature of the fifth swimming leg in both sexes distinguish them from each other. A rare gynandromorphic specimen of E. propecabezasi sp. nov. was recorded, and a revised key to Elaphoidella species in Southeast Asia is provided.

3. Researching "on and in" global south countries : southeast AsiaMohammed Ilyas, 2022, original scientific article Abstract: Over the last decade, there has been an increasing awareness that colonialism continues through various overlapping iterations of coloniality, such as politics, economics, security and academia. Academics from global north countries and global south countries have highlighted and called for the dismantling of coloni-ality in its various iterations. Perhaps the most vocal decolonising calls have come from global north academics wanting to decolonise global north academia in the form of epistemic decolonisation. As such, in this article, I call on global north academics researching 'on and in' global south countries to employ decolonial me-thodologies to avoid inadvertently reinforcing coloniality. By utilising autoethnography and critical decolonial reflexivity, I offer ways for global north academics researching on or in global south countries to guard against reinforcing coloniality during their research.
