Badidae (Chameleonfishes)
Etymology: Badis: 'badis' is presumably a Bengali local name, possibly derived from 'bhedo' or 'bheda', but it lacks a proper reference. Probably incorrect etymology (J. Müller, pers. comm., April 2021, after information from native speakers); dibruensis: Named for its type locality, the Dibru River..

背面の脊椎 (合計) : 15 - 17; 背鰭 (合計) : 8 - 9; 脊つい: 27. Diagnosed from its closest congener, Badis badis in possessing the following combination of characters: two (vs. three) predorsal bones; small oval (vs. large rectangular) black blotch in the mid-base of caudal fin; more interorbital width (9.9-15.0 vs. 6.5-8.3% SL); shorter upper jaw (6.1-6.9 vs.8.2-10.2% SL) and lower jaw (7.1-8.3 vs. 11.3-14.5% SL). Can be differentiated from Badis kanabos in having smaller eye diameter (7.6-9.4 vs. 9.5-12.7% SL); and from Badis tuivaiei in having vertebrae 27 (vs. 31), more interorbital width (9.9-15.0 vs. 5.6-7.2% SL), and shorter upper jaw (6.1-6.9 vs. 8.5-10.4% SL). Distinguished from all three mentioned species by the absence (vs. presence) of dark black or brown vertical bars on sides (Ref. 83458).
