Petrotilapia ?retrognathous? (Petrotilapia palingnathos) fish species information

Scientific Name
Petrotilapia palingnathos

Common Name
Petrotilapia ?retrognathous?

Biology
Adult male and female P. palingnathos have distinctly retrognathous jaws and can thus be distinguished from all other members of Petrotilapia. Furthermore, the absence of a dark submarginal band in the dorsal fin distinguishes P. palingnathos from P. microgalana, P. genalutea, P. nigra, P. chrysos, P. mumboensis, and P. pyroscelos, which have such a band. Adult males of P. palingnathos are dark gray with orange markings and scales outlined in blue with orange cheek and a blue gular area, which distinguishes them from P. tridentiger, which are light blue with dark blue bars, and from males of P. xanthos which are yellow, while those of P. flaviventris are yellow on ventral and mid-sides with scales outlined in blue (Ref/ 87181).
