Etymology: Pseudocrenilabrus: Greek, pseudes = false + Latin, crenulatus = cut + Latin, labrum = lip (Ref. 45335); pyrrhocaudalis: Named Pseudocrenilabrus pyrrhocaudalis because this species has a bright orange tail which resembles a flame of fire (Ref. 114630).

Short description

Ραχιαίες άκανθες (συνολικά) : 13 - 15; Μαλακές ραχιαίες ακτίνες (συνολικά) : 8 - 12; Εδρικές άκανθες: 3; Μαλακές εδρικές ακτίνες: 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).
Body shape (shape guide): fusiform / normal; Cross section: oval.
Found at open beaches (Ref. 114630).
