Morphology | Morphometrics
soft rays: 15 - 18;
Vertebrae: 29 - 30. A closed frontal neuromast system with one groove, preopercular neuromast system with 5 pores (Ref. 82704). First dorsal fin ray behind origin of anal fin, situated above anal fin ray 6-8 (Ref. 82704). Pectoral fin extending posteriorly, not reaching origin of pelvic fin; pelvic fin not or just reaching anal fin (Ref. 82704). Scales cycloid; body and head entirely scaled, except for ventral surface of head; frontal squamation of G-type (Ref. 82704). Nimbapanchax leucopterygius can be distinguished, together with other the other species of Nimbapanchax and Archiaphyosemion species by a white or light blue margin around caudal fin (not always completely closed), a small dark brown or reddish submarginal stripe and brown blotches between fin rays, no yellow zone in fins, and females without or with small spaced dark bars on side (Ref. 81704). Nimbapanchax leucopterygius has no broad brown or red-brown vertical bars or blotches on side in males; the center of many scales in males are metallic blue-green, there is only little red pigmentation on head and sides and a dark brown or red blotch above and slightly posterior to the insertion of pectoral fin on side in females; it has a white or light blue margin and a dark brown or red submarginal band in the anal fin and a blue-green center in unpaired fins with small dark brown or red dots; young males have a pattern of vertical stripes on sides formed by metallic blue-greenish scales, and females have a similar pattern of brown stripes (Ref. 81704).
Type locality is small, slow flowing creek in rainforest, covered by tree canopy; water brownish stained; water temperature 20°C; maximum depth about 40 cm (Ref. 82704).
