Osbornellus trifurcatus Domínguez & Godoy , sp. nov.

( Figs. 49a–49e)

Description. Length: 5.5–6.2 mm. Member of the O. rarus group ( Fig. 1b). Similar to O. libratus .

Male genitalia: Pygofer moderately projected posteriorly, apex very wide, rounded; macrosetae long, dispersed along apical half of pygofer ( Fig.49a). Valve triangular, ventral margins curved, anterior middle curved. Plates short, base wide, tapered to pointed apex, with setae plumose ( Fig. 49b). Style with apophysis long, straight, apex curved and truncate ( Fig. 49c). Aedeagus in ventral view with base quadrate, wide, margins rounded. Ventral processes absent; shaft tapered to apex, with three projections, the middle one slightly longer and pointed, with lateral extensions of dorsal projection ( Fig. 49d). In lateral view shaft curved dorsad, apex with three pointed projections; dorsal projection long, curved caudad, truncate ( Fig. 49e). Gonopore subapical.
