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); pyema: Specific name from the local name 'Nga-pyema' recorded at Putao; Noun in apposition..

Taggstrålar i ryggfenan (totalt) : 16 - 17; Mjukstrålar i ryggfenan (totalt) : 9 - 10; Mjukstrålar i analfenan: 6 - 8; Ryggkotor: 28 - 29. Body extremely slender, body depth 26.3-32.7% SL. Dentary pores 1-2; infraorbital pores 1-2; lachrymal pores 2; extrascapular pore 1. Caudal fin base with a prominent dark spot at the center, surrounded by a light ring. Differs from B. corycaeus in having a slender body, depth (versus 32.5-39.4%SL); more lateral line scales, 27-28 (versus 25-26); more vertebrae, 28-29 (versus 26-29); and color pattern where males are overall light with scattered black spots on each scale on sides. No dark blotch on cleithrum, opercular margin, nor on dorsolateral side of caudal peduncle (Ref. 46238).
Collected from a small, fast flowing stream, about 3 m wide on the average, relatively shallow, less than 0,5 m deep, with occasional riffles; water clear and colorless; the bottom with rock, gravel or sand. This stream ran between forested hills, with grass and shrub close to the margin, providing up to about 75% shadow, but no water vegetation (Ref. 46238).
