简单描述 型态特徵 | 形态测量图

背棘 (总数): 0; 背的软条 (总数): 26; 臀棘 0; 臀鳍软条: 12 - 13. Diagnosis: Distichodus ingae is distinguished from D. affinis, D. altus, D. decemmaculatus, D. noboli, D. notospilus and D. teugelsi by the higher number of lateral line scales, 69-73 vs. 37-46; from D. antonii by the inferior mouth vs. terminal, and the higher number of dorsal-fin rays, 26 vs. 21-25; from D. fasciolatus by the lower number of dark vertical bars, 6-8 vs. 13-20; from D. langi by the lower number of scales between the lateral line and the pelvic-fin base, 10 vs. 12, the lower number of pectoral-fin rays, 19 vs. 21, and the lower number of vertical bars, 9 vs. 13; from D. lusosso by the inferior mouth vs. terminal, and the short snout vs. elongated; from D. maculatus by the absence of dark blotches all over the body; and from D. sexfasciatus by the higher number of dorsal-fin rays, 26 vs. 24-25, the higher number of teeth in the outer row of the upper and lower jaw, 17-18 and 20-21 vs. 12-14 on both jaws, and the greenish body colouration vs. orange-reddish (Ref. 122092). It is distinguished from its most similar species D. atroventralis by having more dorsal-fin rays, 26 vs. 22-24, and longer dorsal fin, 12.0-21.9% of standard length vs. 23.6-24.2%, anal fin, 9.9-15.7% of standard length vs. 16.9-17.5%, and pectoral fin, 14.2-20.5% of standard length vs. 21.6-22.7%; and from D. kasaiensis by having more lateral line scales, 69-73 vs. 57-65, fewer dorsal-fin rays, 26 vs. 27-29, and a longer prepectoral distance, 29.1-30.2% of standard length vs. 21.4-30.0% (overlap due to negative allometry) (Ref. 122092).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
