简单描述 型态特徵 | 形态测量图

背棘 (总数): 0; 背的软条 (总数): 10; 臀棘 0; 臀鳍软条: 25 - 27. Diagnosis: Nannopetersius mutambuei is distinguished from its two congeners by the following combination of characters: lateral line with 28-30 scales and 27-30 pored scales, vs. 30-35 and 32-35 in N. ansorgii and 28-33 and 27-33 in N. lamberti; 5.5-6.5 scales between the origin of the dorsal fin and the lateral line, vs. 6.5 in N. ansorgii and 6.5-7.5 in N. lamberti; 10-13 gill rakers on the ceratobranchial of the first branchial arch, vs. 14-17 in N. ansorgii and 10-12 in N. lamberti; length of caudal peduncle 135.7-151.9% of its depth, vs. caudal peduncle nearly as long as deep in N. ansorgii and N. lamberti; snout length 26.6-29.2% of head length, vs. 18.4-23.0% in N. lamberti; eye diameter 31.7-39.6% of head length, vs. 46.0-56.2% in N. lamberti; and no broad dark band in life, however present in preserved specimens, and no additional black spots on caudal and distal blackish band on anal fin, vs. a faint dark medio-lateral band, in preserved specimens, hardly visible anteriorly but better marked on the caudal fin and no additional black spots on caudal and anal fin in N. ansorgii, and a broad, black, medio-lateral band in life as well as preserved specimens, distal part of both upper and lower caudal-fin lobe with a black spot and distal margin of anal fin blackish in N. lamberti (Ref. 79819).
