🔬 Taxonomy

🐟 Physical Description

Dorsal spines (total): 14 - 16; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 7 - 8. Diagnosis: Parananochromis orsorum is distinguished from P. brevirostris, P. elobatus and P. ornatus by the presence of 4 tubular infraorbital bones vs. 3; from P. brevirostris and P. elobatus by the presence of scales on the chest vs. absence, and a well developed pharyngeal pad vs. weakly developed; and from P. axelrodi by a shallower body depth, being 27,3-33,7% of standard length vs. 35,6-42,2% . It differs from Parananochromis caudifasciatus by a greater preorbital distance, 19-28% of head length vs. 17-19; absence of dots on caudal fin of females vs. rows of dots in females; and more pointed snout . It differs from Parananochromis gabonicus by fewer rows in both jaws, 2 rows in both jaws vs. 2-4 in upper jaw and 2-3 in lower jaw; and in colouration, intense and regular rows of pale blue spots in soft dorsal, caudal and soft anal fins of males, yellow colouration of distal part of anal fin of both sexes, black colouration of tip of pelvic fin of females vs. rows of spots in fins absent or pale and restricted to proximal parts of fins, distal part of anal fin clear, tip of pelvic fin clear to pale white in P. gabonicus . It differs from Parananochromis longirostris by the absence of the following features in P. orsorum: silver centers on body scales in both sexes, red colouration across dorsal portion of eye, spots in dorsal, caudal and anal fins of females; and a smaller size . : fusiform / normal; Cross section: oval.
