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); pallidus: Name from Latin ‘pallidus’ meaning pallid, pale, referring to the uniform light grey body colour of males of this species.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 16 - 18; Raggi dorsali molli (totale) : 9; Vertebre: 28 - 29. This species is distinguished by the following characters: with a dark blotch on exposed cleithrum; no dark blotch dorsolaterally on the caudal peduncle; no short black bars along the middle of the side, nor a dark blotch on the gill cover; no black blotch anteriorly on dorsal fin; no intense black narrow vertical bars on the sides in males; vertebrae 28-29; lateral scale row 27-29; D XVI-XVIII.8½-10; narrow interorbital space 4.6-6.3% SL; scales between the anal fin and upper lateral line 6; circumpeduncular scale rows 15-17 (Ref. 120428).
Collected from small hill streams of the Karnafuli and Sangu Rivers, and downstream, where the slope lessened, of Shailopropat. Falls (Ref. 120428).
