Type specimens. Holotype (unique): BMNH 1906.5.30.84 (studied).
Type locality. Mouth of Katonga River, Lake Victoria (Uganda).
Diagnosis. Preanal length, PAL 0.641 of SL; predorsal length, PDL 0.634 of SL; dorsal fin length, LD 0.155 of SL; anal fin length, LA 0.221 of SL; distance dorsal fin origin to end of caudal peduncle, pD 0.427 of SL; length of caudal peduncle, CPL 0.202 of SL; depth of caudal peduncle, CPD 0.369 of CPL; length of snout to centre of eye, LSc 0.258 of HL; length of snout to posterior orbital rim of eye, LSo 0.411 of HL; head length, HL 0.261 of SL; dorsal fin ray number, nD 19; anal fin ray number, nA 27; number of scales around caudal peduncle, SPc 12.
Etymology. See title of Boulenger (1906): “... new Fishes discovered by Mr. E. Degen... ”.
Remarks. “Easily distinguished from its congeners in the short dorsal fin originating above the first ray of the anal” (Boulenger 1906: 434). Distinguished from all other species by highest PAL / SL and lowest LSc / HL, in combination with low LD / SL, low LA / SL, rather high pD / SL.
