Remarks Purple tail males are characterized by: purple caudal fin; yellow dorsal and anal fins, and pale yellow pelvic fin; ventral half of head yellow. Yellow tail males are characterized by: yellow caudal fin; dorsal, anal and pelvic fins, and ventral half of head pale yellow (paler than those of purple tail males). Both colour morphs have the pelvic fin tip more yellow than the base, which could be an egg spot. The two colour morphs occur in the same population. Females comprise a single colour morph: caudal, dorsal and pelvic fins pale purple, almost pale grey; anal fin pale yellow; ventral half of head greyish. The head, in comparison with the body, tends to be larger in females. the pelvic fin tends to be longer in males (Ref. 55033).

Diagnosis

Recognized as a species of the genus Cyprichromis by the elongate abdominal

cavity, extending posteriorly beyond the anal fin origin. Cyprichromis coloratus n. sp. can be distinguished from C. microlepidotus by fewer scales in the longitudinal line (41-44 v. 59-70 in C. microlepidotus) and in the upper lateral line (31-36 v. 47-59), from C. leptosoma by more spines in the dorsal fin (14-15 v. 11–13 in C. leptosoma) and more scales in the longitudinal line (41-44 v. 38-40), from C. pavo by fewer dorsal-fin spines and soft rays (total number of spines and soft rays 29-31, usually 30, v. 30-32, usually 31, in C. pavo), and from C. zonatus usually by a shallower body [body depth 24.0–28.5 (26.4 +/- 1.1) % LS v. 24.5–30.5 (28.4 +/- 1.3) % in C. zonatus] and smaller eye (eye length (LE)

25.2–30.9 (27.2 +/- 1.1) % of head length (LH) v. 27.9–33.3 (30.2 +/- 1.2) %). Males of the new species are also distinguished from C. microlepidotus, C. pavo and C. zonatus by the following colouration features: absence of distinct small spots on body (v. presence of pearl grey and yellowish small spots along scale rows on body in C. microlepidotus and C. pavo), dichromatism (particularly of the caudal fin) in males of the same population (v. no dichromatism in C. zonatus), and absence of vertical bands on flanks (v. three or four distinct vertical bands beneath dorsal fin base in live males of C. zonatus) (Ref. 57033).
