Abstract

<h3>Abstract</h3> A new species of cichlid fish, <i>Lethrinops atrilabris</i> is described from specimens collected by trawling at a depth of around 90m off Monkey Bay, southern Lake Malawi. It is assigned to the genus <i>Lethrinops</i> on the basis of its vertical flank barring, lack of enlarged cephalic lateral line canal pores and the form of the lower jaw dental arcade. It can be distinguished from congeneric species by its male breeding dress of contrasting flank barring and dark ventral surface, most strikingly on the lips, throat and chest, its relatively small known maximum size (&lt;75mm SL), large eyes (38-41% head length), laterally compressed body (depth 2.5-2.7 times max head width) and lower gillraker count (13-14).
