Osbornellus nielsoni Domínguez & Godoy View in CoL , sp. nov.

( Figs. 60a–60e)

Descripction. Length: 3.7–4.6 mm. Similar to other members of the species O. affinis group ( Fig. 1d).

Male genitalia. Pygofer longer than wide, greatly projecting posteriorly, apex very wide and rounded; macrosetae very long, distributed over the distal third of the pygofer ( Fig.60a). Valve with rounded borders, slightly curved anteriorly in the center. Plates elongate, apex pointed, with a few short setae ( Fig. 60b). Style with apophysis short, curved, rugose on the internal side, and with apex truncate ( Fig. 60c). Aedeagus in ventral view with base wide and straight, slightly curved on lateral margins. Shaft hidden by the processes, but shorter than the latter and with apex truncate ( Fig. 60d). Processes originating about a third of the way along the aedeagus, slightly separated from the base to slightly beyond midlength, then completely separated and diverging, thin with pointed apices. In lateral view shaft curved to midpoint, wide, slightly longer than process, apex tapered; dorsal projection not projecting beyond apex of shaft, generally wide. Gonopore apical. Processes separated near base of stalk, narrow, very long, curved basally and straight apically, apices pointed ( Fig. 60e).

Diagnosis. Genitalia very similar to O. maesi ; in lateral view O. nielsoni has the aedeagal processes very long and straight, the shaft fairly straight. In O. maesi the processes are curved, not very long and the shaft is curved.

Distribution. Known only from Costa Rica; 80– 150 m.

Etymology. This species is named in honor of Merv Nielson for his work on Cicadellidae .
