Clariidae (Airbreathing catfishes)
Etymology: Clarias: Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water; monsembulai: Named in honour of Raoul Monsembula Iyaba, professor of biology, University of Kinshasa, for collecting the type series of this species, and in recognition of his substantial contributions to central African ichthyology (Ref. 127574).

Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Μαλακές ραχιαίες ακτίνες (συνολικά) : 78 - 86; Μαλακές εδρικές ακτίνες: 53 - 64; Σπόνδυλοι: 58 - 61. Diagnosis: Clarias monsembulai can be distinguished from all congeners, with the exception of C. buthupogon, by its exceptionally long maxillary barbels, 60% of standard length or greater, vs. maxillary barbels less than 60% of standard length, usually considerably less (Ref. 127574). It differs from C. buthupogon in the absence of fine, pale spots over the surface of the body and by an exposed bony surface of the cleithrum reaching 14-20% of head length, vs. cleithrum deeply imbedded in soft tissue with only a narrow bony ridge visible externally (Ref. 127574). Clarias monsembulai can be further differentiated from C. angolensis, the species with which it shares closest phenotypic similarity, by longer nasal barbels, 37-51% of standard length vs. 22-34%; longer internal mandibular barbels, 29-37% of standard length vs. 16-27%; longer external mandibular barbels, 45-57% of standard length vs. 24-40%; and by the colouration of maxillary barbels which are white or cream-coloured distally over more than half of their length vs. brown or grey over more than half their length (Ref. 127574).
