Etymology: Labeo: Latin, labeo = one who has large lips (Ref. 45335); mesops: From the Greek word mesos meaning middle or half and opsis meaning sight; name refers to the state of the type material which was only half of the skin (Ref. 26190).

Africa: present in Lake Malawi basin (Ref. 1878, 52161, 55909, 96560), Juba system (1440) and Ruvuma River (Ref. 1440, 97286). Status Tana River population is uncertain (Ref. 52331). Reports from the Lufira River, Upper Congo River basin (Ref. 1440, 26190), are misidentifications of Labeo rosae (Ref. 96560).

Found in shallow water over sandy bottoms (Ref. 5595, 52161). Is a mud-feeder (Ref. 52161), feeds from the biocover and sediment on the sand (Ref. 5595). Also caught using weirs and baskets; formerly very abundant in Malawi, but now rare except where rivers drain undisturbed soil; possible that silt prevents development of eggs (Ref. 4967). Indications that it may leave the lake and run up rivers to spawn (Ref. 52161).
