Sundadanionidae (Tiny danios)
Etymology: Sundadanio: Sunda: Asiatic island; Danio: from ‘dhani’, local Bengali/Bangla name for small minnows (Ref. 2031); gargula: Derived from gar-, an onomatope common to many ancient European language for boiling water or water flowing through a gullet, and from the Latin 'gula', meaning throat; this gave rise to French gargouille and the English gargoyle; in reference to the somewhat grotesque appearance of the head and throat of tuberculate males of this species. A noun in apposition.

Short description
Chiavi di identificazione | Morfologia | Morfometria
Raggi dorsali molli (totale) : 9; Raggi anali molli: 9; Vertebre: 34. Distinguished all its congeners by the greater distance between the dark lateral stripe and the
ventral midline in males (13.5-14.5 % SL vs. 8.7- 13.6) and by its larger and more numerous tubercles (enlarged scales next to window in body musculature with a vertical row of 3-5 large
conical tubercles vs. 1-3; scales posterior to enlarged scales next to window in body musculature and anterior to anal-fin origin with 2 large, closely situated conical tubercles at center vs. 1 or 2 small, widely spaced tubercles). 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).
Inhabits peat swamp forests (Ref. 88800).
