Osbornellus inbio Domínguez & Godoy , sp. nov.

( Figs. 46a–46e)

Description. Length: 5.9 mm. Member of the O. rarus group ( Fig. 1b). Vertex angulate. General color yellowish. Face pale brown with transverse black lines. Transverse apical band of vertex cream colored, narrow, curved, and interrupted (two elongate lateral marks and a rounded central mark); not extending to ocelli, both sides bordered with black. Small, clear, triangular mark extending behind apical band, bordered with dark brown. Wide black mark behind each ocellus. Apex of coronal suture with wide, transverse, dark brown line. Pale yellow mark in form of inverted “T” bordered with a difuse brown line. Area adjoing internal eye margin with pale yellow and dark brown markings. Rest of vertex orange. Prontoum clear colored with various yellowish brown tones and with irregular band along anterior margin. Scutellum with two pale brown triangles on anterior part, bordered by white and brown, pale yellow in center, white marks bordered with brown near base, white basally. Anterior wing yellow, with white marks and a few elongate brown marks; veins brown, usually with brown dots at ends of the costal veinlets, claval veins and claval suture; apical cells with brown marks.

Male genitalia: Pygofer about twice as long as greatest width, moderately projected, apex widey rounded; macrosetae long, dispersed, distributed along apical half ( Fig.46a). Valve ovate, margins rounded, anterior half slightly curved. Plates long, base wide, apex pointed, setae only in the base ( Fig. 46b). Style with apophysis long, curved, apex truncate ( Fig. 46c). In ventral view wide at base, quadrate and irregular; shaft shorter than ventral processes; lateral extension of dorsal projection sharply tapered at tips ( Fig. 46d). Ventral processes arising very close to base of aedeagus, crossing one another at midlength, wide, apices tapering and pointed. In lateral view shaft slender, curved dorsad, shorter than ventral processes, apex rounded; dorsal projection long, slightly curved caudad, apex truncate. Gonopore subapical. Ventral processes separated from shaft, curved caudad, very wide, apices pointed ( Fig. 46e).

Diagnosis. Very similar externally to O. rarus , but in ventral view the aedeagus of O. inbio has the ventral processes crossing one another, whereas in O. rarus the ventral processes do not cross.

Distribution. Known only from Costa Rica; 1850 m

Etymology. This species is named for the National Biodiversity Institute.
