Etymology: Nomorhamphus: Greek, nema = filament + Greek, rhamphos = bill, peak (Ref. 45335); lanceolatus: From the late Latin adjective lanceolatus, meaning lanceolate, in reference to the shape of the spiculus of the new species.

背的软条 (总数) : 11 - 13; 臀鳍软条: 15 - 16; 脊椎骨: 36 - 38. Nomorhamphus lanceolatus can be distinguished from all congeners by the combination of the following characters: lower jaw short; no fleshy lower jaw appendage in males; presence of black pigmentation in anal and dorsal fin; life coloration with yellow and orange colored anal, dorsal, and caudal fin, ventral surface of lower jaw orange and yellow belly; a lanceolate, dorsally slightly curved spiculus in the male andropodium, with the middle segments of the spiculus in contact with the distal tip of the third anal-fin ray; nine to ten segments proximal to spinae (mode nine segments); segments three or four to six or seven (mode four to seven) of second anal-fin ray in males with a dorsal and a ventral row of 'subsegments' forming small squares and rectangles of different sizes, so that these segments seem to be subdivided; third anal-fin ray slightly constricted longitudinally, giving the appearance of two distinct rays, distal part of this ray is slightly curved ventrally to contact spiculus (Ref. 97329).
Occurs in a stream of about 7-9 m wide and 50 cm deep, partially shaded by forest canopy, with a bed of sand and gravel (Ref. 97329).
