Etymology: Distichodus: Greek, di = two + Greek, stix, stichos = line, row (Ref. 45335); langi: Named in honour of the collector, Herbert Lang (Ref. 41594), who collected fish in the Congo basin from 1909 to 1915 for the AMNH, in collaboration with James Chapin (Ref. 96324).

簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 26-28; 臀棘 0; 臀鰭軟條: 14. Diagnosis: Within the Congo basin, Distichodus langi can be distinguished from D. affinis, D. altus, D. decemmaculatus, D. noboli, D. notospilus and D. teugelsi by its higher total number of lateral line scales, 68-70 vs. less than 46; from D. maculatus by the absence of large, dark spots all over the body and a higher number of dorsal fin rays, 26-28 vs. 19-21; from D. antonii by its inferior, vs. terminal, mouth, its higher number of scales between the lateral line and the dorsal fin, 15-16 vs. 10-12, and its higher number of lateral line scales in front of the hypural joint, 68-70 vs. 52-64; from D. fasciolatus by its higher number of dorsal fin rays, 26-28 vs. 24-26, its higher number of pelvic fin rays, 11 vs. generally 10, and its deeper head, 67.4-69.4% of head length vs. 35.9-62.9% of head length; from D. lusosso by its inferior, vs. terminal, mouth and feebly compressed snout, vs. distinctive prolonged; from D. sexfasciatus by its feebly compressed snout, vs. strongly compressed, its higher number of dark vertical bars along the body, 13 vs. 6-7, and its higher number of teeth on the outer row on both jaws, more than 20 vs. 12-14; and from the D. atroventralis complex by a higher number of scales between the lateral line and pelvic fin, 12 vs. 9-11, its higher number of pectoral fin rays, 21 vs. 17-20, its higher number of circumpeduncular scales, 24-25 vs. 20-24, and its deeper head, 67.4-69.4% of head length vs. 35.1-55.7% of head length (Ref. 96324).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [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 to moderate vulnerability (34 of 100).
