Abstract

Two cichlid fishes from Lake Tanganyika,Xenotilapia sima Boulenger, 1899 andX. boulengeri (Poll, 1942) are often confused owing to insufficient information on the diagnostic morphological characters for each species. Morphological and morphometric analyses showed thatX. sima differs fromX. boulengeri in having a greater number of teeth and anal and pectoral fin soft rays, thicker caudal peduncle, larger eyes, and a shorter snout and anal fin base.
