Short description
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 17 - 19; Radios blandos dorsales (total) : 8 - 10; Espinas anales: 3; Radios blandos anales: 7 - 8. Diagnosis: The dark submarginal band in the spinous part of the dorsal fin of both male and female distinguishes Petrotilapia pyroscelos from P. tridentiger, P. xanthos, P. flaviventris, and P. palingnathos, which lack such a band (Ref. 87181). Males of P. pyroscelos have blue and bronze ground color with 7-9 gray vertical bars, whitish to gray throat and purple cheek, which distinguishes it from P. genalutea, P. nigra, P. chrysos, P. microgalana and P. mumboensis; males of P. genalutea are dull gray-blue with 5-7 black vertical bars, have an orange-yellow cheek, and a black throat; males of P. nigra and P. chrysos are predominantly blue-black with 7-10 gray/brown bars, have a dark blue cheek, and a black throat; males of P. microgalana are bright blue with 5-7 faint black vertical bars, and have a light blue cheek and a yellow throat, while those of P. mumboensis are blue with 8 dark blue vertical bars, light blue cheeks, and a light blue to gray gular region (Ref. 87181). Females of P. pyroscelos are brown with faint blue and yellow highlights with a conspicuous black submarginal band in the dorsal fin; females of P. pyroscelos are distinguished from those of P. genalutea, P. nigra, P. chrysos, and P. microgalana by the brown to gray ground color on the flank which is beige or yellow in the other species and are distinguished from females of P. mumboensis which lack any horizontal elements of the flank’s pigmentation pattern (Ref. 87181).
