Pelvicachromis signatus and Pelvicachromis rubrolabiatus, two new cichlid species (Teleostei, Perciformes) from Guinea, West Africa

Abstract

Pelvicachromis rubrolabiatus and P. signatus are described from Guinea. They differ from other members of Pelvicachromis, except P. humilis, in having two contiguous tubular infraorbital ossicles instead of three with a gap between the 2 nd and 3 rd and in displaying a color pattern of seven to eight dark vertical bars during certain behavioral situations. Pelvicachromis rubrolabiatus differs from P. humilis and P. signatus in having seven instead of eight vertical bars on the body and from P. signatus in having a lesser preorbital depth. Pelvicachromis signatus differs from P. humilis in the presence of characteristic black markings in the dorsal and caudal fin of males, a black spot on the caudal peduncle of females and occasionally one or two black spots in the female s dorsal fin.
