Abstract

Hypsopanchax stiassnyae, new species, is described from recent collections in the Lulua River (Kasaï drainage). All Hypsopanchax species from the southern Congo drainage share a similar supra-orbital cephalic sensory system, that differs from the characteristic zigzag shaped system of the three northern species H. catenatus, H. platystemus, H. zebra, and Platypanchax modestus. Most probably H. jobaerti is the closest relative of this relatively small species, based on shared characters of the supra-orbital sensory system. Hypsopanchax stiassnyae differs from H. jobaerti in adult male fin colour pattern, dorsal profile, body depth, and length of dorsal and anal fin base in females. © 2015 by Verlag Dr. Friedrich Pfeil, München, Germany.
