Osbornellus costaricensis Domínguez & Godoy

sp. nov.

Osbornellus costaricensis Domínguez & Godoy , sp. nov.

( Figs. 33a–33e)

Description. Length: 6.2 mm. Member of the O. rarus group ( Fig. 1b). Vertex angulate, median length about equal to distance between eyes at posterior margin ( Fig. 1b). General color and vertex similar to O. rarus ; rest of vertex mottled yellow-brown; coronal suture brown, bordered with white. Pronotum as in O. rarus . Scutellum mottled yellow-brown with yellow at center, bordered with pale yellow laterally, brown spot in basal angle margined with orange, posteriorly with white spot along each lateral margin. Anterior wing as in other members of this species group.

Male genitalia: Pygofer about twice as long as greatest width, moderately projected posteriorly, apex wide and rounded; macrosetae medium-sized, few in number, dispersed along apical third of pygofer ( Fig. 33a). Valve triangular, margins rounded on anterior half, slightly curved. Plates short, base very wide, tapered from middle to apex, apex rounded, with a few short, dispersed setae ( Fig. 33b). Style with apophysis long, straight, apex truncate ( Fig. 33c). In ventral view aedeagus wide at base, curved in the middle, uniformly wide and straight; shaft shorter than ventral processes, hidden by ventral processes; lateral extensions of dorsal projection just showing to each side of ventral processes ( Fig. 33d). Gonopore subapical. Ventral processes arising close to base of aedeagus, crossing one another, wide, tapered to pointed apices. In lateral view shaft wide, curved caudad in the middle, apex rounded, shorter than ventral processes; dorsal projection expanded, truncate, straight. Ventral processes very separated from shaft basaly, with basal spine, straight but slightly curved dorsad, apices narrow and rounded ( Fig. 33e).

Diagnosis. Very similar externally to O. rarus and O. latus , but in ventral view the ventral processes of O. costaricensis cross one another in the apical fourth and there is a spine at the base of the processes. In O. latus and O. rarus the ventral processes do not cross and lack a spine.

Distribution. Known only from Costa Rica; 2640–2700 m.

Etymology. This species is named for the country in which it has been collected.
