Short description
Identification keys | Morphology | Morphometrics
Dorsal soft rays (total): 10 - 12; Anal soft rays: 10 - 12; Vertebrae: 37 - 39. Differs from N. towoetii and N. celebensis which are also found in Kolonodale in having a short lower jaw 8.8-22.2 times in SL (versus upper and lower jaws about the same length); long upper jaw (length/width 1.1-2.1 versus 0.7-1.3). Gill rakers teardrop shaped usually without teeth (versus with many teeth). Fifth hypural partially separate from dorsal hypural plate along most of its length (versus completely fused) (Ref. 45130).
Body shape (shape guide): elongated; Cross section: compressed.
A viviparous species collected from a variety of habitats including small, clear, cool mountain streams with rocky, muddy bottoms; shallow pools (0.02-0.50 m); muddy shorelines among tangles of roots; the base of small waterfalls among reeds; and under riverine canopies. (Ref. 45130).
