背棘 (总数) : 13 - 16; 背的软条 (总数) : 9 - 12; 臀棘: 3; 臀鳍软条: 7 - 8; 脊椎骨: 24 - 25. Diagnosis: relatively deep-bodied (Ref. 52307, 81260), particularly so in large specimens (depth 27.8-40.2% SL)(Ref. 8160). Head short (HL 31.9-37.2% SL); snout generally shorter than postorbital length; ascending process of premaxilla about one third longer than dentigerous arm; outer and inner row teeth in oral jaws unicuspid (Ref. 81260). Laterosensory system in the lachrymal bone with 5 openings (Ref. 45129, 52307, 81260). Infraorbital series complete (lachrymal bone and 4 other)(Ref. 45129, 81260). First pelvic fin ray longest in adults of both sexes (Ref. 45129), usually reaching anus or beyond (Ref. 81260). Pectoral fin somewhat shorter than pelvic; some dorsal and anal rays produced (branched dorsal rays 4-6, branched anal rays 4-5 longest), upper and lower caudal rays also produced in both sexes; caudal peduncle somewhat deeper than long (Ref. 81260). 2.3-3 scales between highest point of upper lateral line (about the 8-9th pored scale) and dorsal fin base; between the last 2-4 pored scale and the dorsal fin base 1 or 1 large and 1 very small scale (Ref. 45129). 12 circumpeduncular scales (Ref. 45129, 81260). Chest scales markedly smaller than flank scales (Ref. 81260). No sexual dimorphism in morphology or coloration (Ref. 45129). Coloration: base body colour pale brown, cheeks and ventrum somewhat paler; usually 6-7 vertical bars on flanks; opercular spot well marked; reddish black maculae on caudal, soft dorsal and anal fins, often forming distinct bands proximally on the fins (Ref. 81260). Dorsal, anal and pelvic fins (Ref. 81260), and upper (Ref. 52307, 81260) and lower (Ref. 52307) edge of caudal fin, with narrow red margin (Ref. 52307, 81260), caudal fin also with thin white submargin (Ref. 52307). Lower edge of caudal with white margin; metallic (silvery) flush below red margin on soft dorsal fin (Ref. 81260).
Body shape (shape guide): short and / or deep; Cross section: compressed.

生物学特性     字汇 (例如 epibenthic)

Inhabits the middle and lower parts of the river basins; collection sites are in regions with primary or secondary forests. The water is clear with transparency of more than 100 cm, acidity approximately neutral (pH 7-7.5) with low conductivity (50 µS) and temperatures 21-22°C. The species lives syntopically with Chromidotilapia mamonekenei, which is more abundant than D. albimarginatus (Ref. 45129). Feeds on small particles (both animal- and plantbased), detritus and aufwuchs (Ref. 52307). Polygamous, ovophilic, female mouthbrooder (Ref. 81260). Possibly larvophilic (Ref. 52307).

栖息于河流域的中下游的部份; 采集点是在具有初期的或次级森林。 水用低的导电率 (50 μ S) 与温度 21-22 ° C. 大约对超过 100 公分的透明酸度感到清澈中性 (酸硷度 7-7.5) 此鱼种生命与 Chromidotilapia mamonekenei 有邻接关系, 是比 D. albimarginatus 更丰富.(参考文献 45129)
