Etymology: Cynolebias: Greek, kyon = dog + Greek, odous = teeth + Greek, lebias = a kind of small fish (Ref. 45335); rectiventer: Dervied from the Latin rectus, meaning straight, and venter, meaning belly. This is in reference to the straight ventral profile of the body in males, a condition unique in Cynolebias..

Short description Bestämningsnycklar | Morfologi | Morfometri

Mjukstrålar i ryggfenan (totalt) : 15 - 20; Mjukstrålar i analfenan: 18 - 21; Ryggkotor: 35 - 37. Cynolebias rectiventer can be diagnosed from all species of C. perforatus group by the following characters: contact organs restricted to the seven uppermost rays of the pectoral fin in males (vs. contact organs on all rays); ventral process on the autopalatine present (vs. absent); scales absent on the base of the dorsal fin (vs. present); gill rakers slightly curved (vs. bowed); denticles situated on the gill-raker margin (vs. on the entire region); less than one third of caudal fin anteriorly covered by scales (vs. more than one third). It also differs from all congeners by having approximately straight lateral profile of the abdominal region in males (vs. convex) (Ref. 97357).

Found in two adjacent and shallow temporary lagoons of about 1.0 m deep with an area of about 5 km2, within a small farm for cattle breeding, and with sparse aquatic vegetation. Collected close to the lagoon bottom (Ref. 97357).
