Etymology: Distichodus: Greek, di = two + Greek, stix, stichos = line, row (Ref. 45335);  fasciolatus: The species name "fasciolatus" is derived from the Latin word "fascia", meaning "band, bandage, girdle, zone, strip, stripe" with "fasciola" as a diminutive and most probably refers to the well-marked transverse bars on the flanks (Ref. 96324).

Africa: widespread in the Congo River basin, from the marine Lower Congo up to the upper Lualaba (Ref. 96324), but absent from the Luapula-Moero (Ref. 2970, 96324). Reports from Lake Tanganyika (Ref. 4967, 6770, 36901) are questionable and probably incorrect (Ref. 96324).

背棘 (总数) : 0; 背的软条 (总数) : 24 - 26; 臀棘: 0; 臀鳍软条: 12 - 16. Diagnosis: Within the Congo River basin, Distichodus fasciolatus can be distinguished from D. affinis, D. altus, D. decemmaculatus, D. noboli, D. notospilus and D. teugelsi by its higher total number of lateral lina scales, 61-70 vs. less than 46 in the six other species, and from D. maculatus by the absence of large, dark spots all over the body, instead of 13-20 vertical dark bars, and a higher number of dorsal fin rays, 24-26, vs. 19-21 (Ref. 96324). It can be distinguished from D. antonii by its inferior mouth, vs. terminal, and its higher number of scales between the lateral line and the dorsal fin, 13-16 vs. 10-12; from D. lusosso by its inferior mouth, vs. terminal, its feebly compressed snout, vs. distinctively prolonged, and its higher number of dark vertical bars along the body, at least in specimens larger than 150 mm standard length, 13-20 vs. 6-8; from D. sexfasciatus by its higher number of teeth on the outer row of both jaws, 20-30 vs. 12-18, its higher number of dark vertical bars on the flanks, at least in specimens larger than 150 mm standard length, 13-20 vs. 6-8, and its brownish-yellowish colouration vs. orange-reddish to red (Ref. 96324). Moreover, Distichodus fasciolatus can be differentiated from both the D. atroventralis complex and D. langi by its lower number of pelvic fin rays, 10, exceptionally 11, vs. 11, exceptionally 10 for the D. atroventralis complex and always 11 for D. langi; from the D. atroventralis complex by its higher number of dark vertical bars, at least in specimens larger than 150 mm standard length, 13-20 vs. 6-9, and presence of pale pelvic fins, at least in specimens larger than 200 mm standard length, vs. blackish; and from D. langi by a combination of characteristics: 24-26 total dorsal fin rays, vs. 26-28, and a lower head depth, 35.9-62.9% of head length for specimens of comparable size, vs. 67.4-69.4% of head length (Ref. 96324).

生物学特性     字汇 (例如 epibenthic)

Distichodus fasciolatus is a bottom-dweller in streams, found near the muddy bottom in lakes, large rivers and their dead-ending branches (Ref. 96324). This species is mainly herbivorous, though insects and nematodes were also found in the stomachs (Ref. 96324). The fry are born near the river banks just before the April or December floods and feed on zooplankton and insect larvae in the flooded zones; adults mainly feed on insect larvae, aquatic plants, leaves and seeds (Ref. 96324).
