sp. nov.

Osbornellus villamillsiensis Domínguez & Godoy , sp. nov.

( Figs. 42a–42e)

Description. Length: 4.8–5.0 mm. Member of the O. rarus group ( Fig. 7). Vertex angularly produced, median length about equal to width between eyes at posterior margin. General color orange-brown. Vertex with narrow pale band along anterior margin connecting ocelli, bordered posteriorly by narrow brown band; small triangular pale dot just back of marginal lines in middle, more or less bordered with brown. Most of vertex orange-brown; coronal suture brown, bordered anteriorly with orange marks, posteriorly bordered with irregular pale brown-orange marks. Pronotum anteriorly with orange area, posteriorly mottled with dark brown and yellow. Scutellum with wide median brown band bordered with narrow pale yellow band and large orange spot in basal angles; white spot in corners and along lateral margins. Anterior wing, transparent, yellowish-orange with some white patches, especially along commisural line, appendix yellow; brown spots at apices of claval suture, claval vein and costal vein; some veins marked with brown near their tips.

Male genitalia: Pygofer about twice as long as greatest width, moderately projected, apex widey rounded; macrosetae long, dispersed along apical third of pygofer ( Fig. 42a). Valve wide, margins rounded, curved in the anterior half. Plates long, base wide, tapered to rounded apex, setae short and dispersed ( Fig. 42b). Style with apophysis long, curved, narrow, truncate, apex sharp ventrally ( Fig. 42c). Aedeagus in ventral view wide at base, curved; shaft narrow, straight, shorter than ventral processes, apex pointed ( Fig. 42d). Ventral processes divergent, wide, long, apices pointed and divergent. In lateral view shaft with wide base, curved dorsad, small notch before apex, apex rounded, aedeagus shorter than ventral process; dorsal projection short, straight, narrowed at tip. Gonopore subapical. Ventral processes separated from shaft from the base and curved ventrad, apices pointed ( Fig. 42e).

Diagnosis. Very similar externally to O. rarus and in genitalia similar to O. expositus , but in lateral view the aedeagal shaft of O. villamillsiensis is slightly wide, curved, and semicircular. In O. rarus and O. expositus the shaft is longer and wider, and is not semicircular in shape.

Distribution. Known only from Costa Rica; 100–3000 m.

Etymology. This species is named for the type locality.
