Discussion. The monotypic genus Kuauna was erected for the species Kuauna schmidi Martins and Galileo, 2009 ( Fig. 8d ), which was described from a single specimen collected in Venezuela. Based on the illustrations in the original descriptions of both species, K. schmidi is synonymized with Ophthalmocydrus semiorbifer Aurivillius, 1925 ( Fig. 8 a-c), previously known only from Colombia. Thus, Kuauna Martins and Galileo, 2009 ( Lamiinae : Pteropliini ) becomes a synonym of Ophthalmocydrus Aurivillius, 1925 .

Specimens of Ophthalmocydrus are rare in collections. Close examination of a female specimen of O. semiorbifer (USNM) revealed a combination of characters which do not fit the definition of Onciderini : antennomere IV longest; frons strongly convex; lower lobe of eyes distinctly large, about 5 times taller than genae; and elytral apices individually truncate, forming acute points at outer margins. Based on these morphological characters, the genus Ophthalmocydrus is transferred to Pteropliini and the known range of the genus is extended to Venezuela.
