Abstract
A new cichlid, Neolamprologus longicaudatus sp.nov. is described, based on three specimens from the north Zairean coast of Lake Tanganyika. Although similar to N. furcifer, N. christyi and N.buescheri in having an elongate body, strongly emarginate caudal fin, and vertical fins partly covered with scales, this species is distinguishable from them by its small orbit, light grayish-brown coloration of body, dorsal fin lacking a submarginal dark band, 37 longitudinal body scales, 8 gill rakers on lower limb of the 1st gill arch, and a long pointed snout.
