摘要根据采自赞比亚坦噶尼喀湖沿岸的21个标本，描述了一种新的丽鱼科鱼类-带形丽鱼。与其同源种细体鲤、细鳞鲤和浅斑鲤的区别在于，其纵行鳞片数为39-43片（而细体鲤为57-71片）。小鳞龙（C. microlepidotus），上侧线鳞片29 -36片（C.小鳞鱼（C. microlepidotus）背鳍刺数为14 ~ 15根（C. leptosoma，C. pavo），一般较深的身体（SL为24.5-30.3%，C为23.1-26.2%。小鳞蟹C. pavo），尾柄较深（SL为9.9-11.1%，C为8.4-9.9%）。小鳞虫C. pavo）、胸鳍较长（27.1- 33.0%SL比23.1-27.4%）。细体线虫占23.0-27.3%; microlepidotus），尾鳍无二色性（相对于雄性C. leptosoma），和三个或四个明显的垂直带下背鳍基部活男性（与缺乏或非常模糊的其他物种）。
Abstract Cyprichromis zonatus, a new cichlid species, is described on the basis of 21 specimens from the Zambian coast of Lake Tanganyika. It differs from its congeners, Cyprichromis leptosoma, Cyprichromis microlepidotus, and Cyprichromis pavo, by having 39–43 scales in longitudinal line (vs 57–71 in C. microlepidotus), 29–36 upper lateral line scales (vs 49–60 in C. microlepidotus), usually 14 or 15 dorsal fin spines (vs 12 or 13 in C. leptosoma, usually 16 in C. pavo), a generally deeper body (24.5–30.3% SL vs 23.1–26.2% in C. microlepidotus, 24.5–26.4% in C. pavo), deeper caudal peduncle (9.9–11.1% SL vs 8.4–9.9% in C. microlepidotus, 9.3–9.9% in C. pavo), longer pectoral fin (27.1–33.0% SL vs 23.1–27.4% in C. leptosoma, 23.0–27.3% in C. microlepidotus), caudal fin dichromatism absent (vs blue and yellow dichromatism in male C. leptosoma), and three or four distinct vertical bands beneath the dorsal fin base in live males (vs absent or very indistinct in other species).
