Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 13 - 15; Dorsal soft rays (total): 8 - 12; Anal spines: 3; Anal soft rays: 6 - 10. Diagnosis: Pseudocrenilabrus pyrrhocaudalis can be differentiated from the other species of the genus Pseudocrenilabrus on the basis of its colour pattern and its subtruncate caudal fin (Ref. 114630). Male P. pyrrhocaudalis have a unique colour pattern characterized by some orange colour on their anal and caudal fins that can become bright orange-red in breeding males, extending over the proximal parts of the anal and caudal fins and the distal part of the caudal and the upper and lower parts of the caudal peduncle (Ref. 114630). In addition, P. pyrrhocaudalis can be distinguished from its sympatric congener P. philander by a combination of the following characters: pelvic fin white, vs. black; posterior part of dorsal fin orange, vs. olive green in the other species; comparatively thinner lips, vs. comparatively thicker lips; larger eye diameter 27.0–39.3% of head length, vs. 22.9–33.1%; narrower head width 37.0–47.3% of head length, vs. 38.5–53.7%; narrower interorbital distance 14.6–22.3% of head length, vs. 20.5 29.4%; and a more slender caudal peduncle 8.8-11.8% of standard length, vs. 11.3–13.9%, and 50.0–64.7% of caudal peduncle length, vs. 64.3–93.5% (Ref. 114630).
Found at open beaches (Ref. 114630).
