Genus Olivensa Lane, 1965

Olivensa Lane 1965: 318 ; Olivensa mimula Lane 1965 : original designation and monotypy; Martins and Galileo 1993: 171; Martins and Galileo, 2014: 113, 224–225.

From Martins (2014):

“species with large head, larger than thorax, without any tubercles on frons of males. Eyes entire. Upper ocular lobes as distant as four times their width. Antennas with eleven segments, longer than body at males and shorter at females; row of internal setae of variable density. Scape subcylindrical, as long as third segment half; apex of scape reaching approximatively anterior quarter of prothorax. Segment III not widened, with sparse setae on internal side, as long as segment IV. Segments V to XI of progressively decreasing length. Segment XI not modified.

Prothorax wider than long and with anterior and posterior width equal (excepted at O. cephalotes , wider anteriorly); sides without gibbosity. Pronotum regularly convex. Elytra without carina or with short carina disappearing after half length. Elytral apex rounded. Metafemora sublinear; apex ultrapassing anterior margin of first urosternite. Tarsal claws with internal teeth shorter than external one. Thoracic sterna and sides of urosternites covered with dense pilosity.”

Genus Olivensa is represented by three species in the northern part of South America: O. cephalotes (Pascoe, 1858) from Ecuador, Brazil (Pará), and French Guiana; O. megacephala ( Bates, 1866) from Bolivia, Ecuador, Brazil (Amazonas), and French Guiana; and O. mimula Lane, 1865 , type-species, from Colombia and Brazil (Amazonas). We propose to add a fourth species, at this time only known from French Guiana.
