Hylobothynus Ohaus, 1910

( Figs. 40 – 48 )

Hylobothynus Ohaus, 1910: 677 . Type species: Hylobothynus obesus Ohaus, 1910: 678 .

Diagnosis. The apical maxillary palpomere is triangular and expanded towards the apex (Fig. 6E), a unique character among the genera of the tribe. Furthermore, members of the genus can be recognized by the following: clypeus triangular, strongly narrowed towards apex, with 2 apical teeth; frontal carina evident; mandibles tridentate; protibia with 3 teeth; males with protarsi not enlarged.

Distribution. Hylobothynus is mainly an Amazonian genus ( Ratcliffe 1981), currently containing five South American species; one from French Guiana; two from Colombia, Ecuador, and Peru; and two from Brazil. However, these species are not common in Colombia, and there have been no recent collections, so only type material was available. Therefore, only a diagnosis is shown for each species.
