Oxathres Bates, 1864

Oxathres Bates, 1864: 50 ; Monné, 1976c: 585 (rev.); 2005: 112 (cat.).

Type-species: Oxathres navicula Bates, 1864 (Monné designation, 1976: 586).

The genus Oxathres Bates was revised by Monné (1976) and included descriptions of three new species. Since then another new species was described by Monné (1990) resulting in ten species in the genus. Oxathres belongs to the group of genera ( Xylergates Bates, 1864 , Proseriphus Monné, 2005 , Brevoxathres Gilmour, 1959 and Sciadosoma Melzer, 1934 ) that share partially the following characters: setae in the surface of the elytra, upper lobes of the eyes separated one or two times the width of a lobe, elytra without centro-basal crista, lateral sides of the prothorax with tubercle or subrounded. In the genus Brevoxathres Gilmour, 1959 the upper lobes of the eyes are separated by three or more times the width of a lobe; in Sciadosoma Melzer, 1934 , there is no visible ovipositor; in Proseriphus the setae in the surface of the elytra are mixed with green scales and in Xylergates there are three tubercles in the surface of the pronotum. Oxathres differs from the above genera by the upper lobes of the eyes separated one or two times the width of a lobe, elytra without green scales, the presence of a short ovipositor and pronotum without tubercles.

Most species of Oxathres were known from Brazil (Amazon basin and Atlantic Rainforest); in the present paper new species are described from French Guiana, Brazil and Bolivia.
