Abstract

Channallabes sanghaensis sp. n., an anguilliform clariid from the vicinity of Ntchouo (Congo River drainage) is distinguished from other Congolese anguilliform clariids by the following combination of characters : a large foramen on the fourth post-Weberian vertebra; two large lateral processes on the second dorsal fin ray pterygiophore; a small supraorbital process on infraorbital IV, not reaching the rostral border of the eye; a fenestra between the scapulo-coracoid and the cleithrum; an interdigitation zone between the quadrate and the entopterygoid; serrations on both sides of the pectoral spine; 86–89 vertebrae; 121-125 dorsal fin rays and 104-124 anal fin rays. An updated identification key is given for the six species of Channallabes.
