Etymology: kumwera: The name kumwera means 'south' in Chichewa, alluding to the species' distribution in the southern part of Lake Malawi, and it is used as a noun in apposition (Ref. 119465).

Kurzbeschreibung
Bestimmungsschlüssel | Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt) : 17 - 19; Rückenflossenweichstrahlen (insgesamt) : 8 - 10; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 7 - 8. Diagnosis: The steeply-sloped vomer without a swollen rostral tip, a small mouth, retrognathic jaws, and the presence of bicuspid teeth in the outer rows of the oral jaws and enlarged conical teeth at the back of the jaws place this species in Tropheops (Ref. 119465). Tropheops kumwera, body depth 23.6-31.0% of standard length, cannot reliably be distinguished from other Tropheops in body depth, 26.6-34.5% of standard length; it does have relatively smaller eye than other Tropheops, horizontal eye diameter 25.8-32.6% of head length and vertical eye diameter 24.2-31.4% of head length vs. 31.2-43.8% and 29.9-43.3% respectively, except T. kamtambo with 26.3-30.2% and 24.0-29.7% respectively (Ref. 119465). It can often be distinguished from T. kamtambo by a shallower head depth than in T. kamtambo, head depth 70.2-84.5% of head length vs. 79.4-97.1%; males of T. kumwera in territorial colour are distinguished from those of T. biriwira by their blue ground colouration and a blue dorsal fin, which are olive green/light blue and yellow-green in T. biriwira respectively; breeding male T. kumwera usually exhibit only the first 3-4 flank bars while male T. kamtambo exhibit all 9-10 bars; female T. kumwera lack a submarginal band in the dorsal fin which is present in female T. kamtambo (Ref. 119465).
