背鰭 (合計) : 9; 臀鰭: 9; 脊つい: 34. Distinguished from all congeners by the following combination of characters: large adult size (largest specimen examined 19.7 mm SL); live males with emerald blue-green sheen present across dorsal body surface and an intense black-red marking across anterior portion of anal fin; preserved males with a well developed dark lateral stripe of roughly uniform depth along entire length, horizontal through ventral border of which, when brought forward, extending
through dorsal half of eye; presence of a weak secondary lateral stripe of small melanophores
running parallel to dark lateral stripe along its ventral margin from posterior to opercular
opening to point opposite middle of anal fin; secondary lateral stripe of males not visible in
live specimens; absence of reticulate pattern over dorsal body surface; absence of dusky markings on distal tips of dorsal and caudal fins; presence of enlarged scales next to window in body musculature; scales posterior to enlarged scales next to window in body musculature and anterior to anal-fin origin with a single small tubercle at center; complete covering of scales on caudal peduncle (Ref. 88800).
Body shape (shape guide): fusiform / normal.
Inhabits swamp forests and blackwater streams (Ref. 88800).
