Osbornellus emmeni Domínguez & Godoy , sp. nov.

( Figs. 21a–21e)

Description. Length: 5.7 mm. Member of the O. auronitens group ( Fig. 1a). General description as in O. eberhardi .

Male genitalia: Pygofer less than twice as long as width, moderately projected posteriorly, narrow and rounded at apex; with very long macrosetae dispersed along apical half ( Fig. 21a). Valve triangular. Plates very long, rounded at apex and with filamentous setae ( Fig. 21b). Style with apophysis short and truncate ( Fig. 21c). Aedeagus in ventral view wide basally, then slightly narrowed; shaft with apex truncate and slightly shorter than ventral processes ( Fig. 21d). Ventral processes arising at one-third the length of the aedeagus, separated distally, tapered, apices sharp. Shaft in lateral view curved dorsad; dorsal projection short and truncate. Gonopore apical. Ventral processes curved dorsad, tapered, apex sharp, separated distally from shaft ( Fig. 21e).

Diagnosis. Very similar in appearance to O. barletti , but in ventral view the aedeagal shaft and ventral processes of O. emmeni are slightly curved dorsad. In O. barletti they are more curved, especially the shaft.

Distribution. Known only from Costa Rica; 2050 m.

Etymology. This species is named in honor of Daniel Emmen in recognition of his loan of specimens and providing laboratory facilities for the first author.
