The Cichlid Fishes of Lake Malawi, Africa

Abstract of Publication

Stauffer, J.R., Jr., and E. Hert. 1992. Pseudotropheus callainos, a new species of mbuna (Cichlidae), with analysis of changes associated with two intra-lacustrine transplantations in Lake Malawi, Africa. Ichthyological Exploration of Freshwaters 3 (3): 253-264.  

Pseudotropheus callainos, a new species of the P. zebra complex, is distinguished from other members of this complex by the blue color of the males, the blue and white color morphs of the females, and the absence of vertical bars. This species is native to the Nkhata Bay area of Lake Malawi, but has been transplanted into southern Lake Malawi. Multivariate analysis of variance (MANOVA) demonstrates that clusters formed by plotting the sheared second principal component (morphometric data) against the first factor score (meristic data) of the transplanted and native populations are significantly different (P<0.01) from each other. Furthermore, the northern (native) and southern (transplanted) populations of P. aurora are both morphologically and ecologically different.
