Can be further distinguished by the following combination of characters: large adult body size (largest specimen examined 19.0 mm SL, smallest tuberculate male 15.2 mm SL); live males with blue to emerald green sheen present across dorsal body surface and an intense red colour across anterior portion of anal fin; preserved males with a highly developed dark lateral stripe of uniform intensity along its entire length, horizontal through ventral border of which, when brought forward, extends through dorsal half of eye; absence of secondary lateral stripe in preserved males; absence of reticulate pattern along dorsal body surface; absence of dusky markings on dorsal and caudal fins; complete covering of scales on caudal peduncle (Ref. 88800).
