CHILOGLANIS PRODUCTUS, A NEW SPECIES OF SUCKERMOUTH CATFISH (SILURIFORMES: MOCHOKIDAE) FROM ZAMBIA

Chiloglaizis productus, new species, is described from the Lunzua River, which drains into the southern tip of Lake Tanganyika in Zambia. It is easily distinguished from congeners in having a color pattern consisting of a pale midlateral stripe on a purplish gray body and without any other distinct pale patches or bands, and by the nature of its sexual dimorphism in caudal fin shape: males have a produced caudal fin (vs. diamond shaped, forked or trilobate in males of otlicr sexually dimorphic congeners).
