Betta hendra spec. nov. is described from Kalimantan Tengah, Borneo, Indonesia. It is a bubble-nesting fighting fish of the B. coccina species group. The new species differs from the other members of the group by a bright greenish iridescent colour on the flanks and unpaired fins. It is distinguished from its geographical neighbour species B. uberis by a lower number of dorsal-fin rays (10–12 versus 14–17).

Parosphromenus gunawani spec. nov. (previously known as P. spec. “Danau Rasau”) and P. phoenicurus spec. nov. (previously known as P. spec. “Langgam”) are described from Sumatra, Indonesia. Parosphromenus gunawani is similar to P. bintan but differs from it by lacking the prominent broad blue band in the caudal fin of males. It is distinguished from the remaining species of the genus by an unique combination of meristic and colour character states. Parosphromenus phoenicurus can be distinguished from all the other species of the genus by the rhombic caudal-fin shape in males (versus round or lanceolate with filaments).

Badis juergenschmidti sp. n. is described from south central Myanmar. The new species is easily distinguished from its congeners by the lack of conspicuous spots on posterodorsal corner of opercle and superfi cial part of cleithrum, caudal fin with contrasted white margin posterodorsally and posteroventrally in adult males. A new numbering standard for the vertical bar pattern is provided. Notes on habitat and reproductive behaviour of the herein described species are given.
