Diagnosis.

This new species, which lacks spines at the phallic apex, is placed in the N. okopa group of Keth et al. (2015), with closest similarity to N. abbreviata Flint, 1983 from Uruguay and N. okopa Ross, 1939 from throughout North America. The new species is separated by the triangular inferior appendage in lateral view, and the lack of a posterolateral process from segment IX.

Description.

Male. Total length 1.6 mm (n = 2), 18 antennal segments, wings and body brown in alcohol. Genitalia (Fig. 16 ). Abdominal segment VIII annular. Segment IX in lateral view anteriorly tapering to short apodeme, posteriorly rounded, short truncate lobe posteroventrally; ventrally divided into two posterior bands; dorsally with anterior margin incised, posterior shallowly emarginate. Segment X triangular in lateral view; in dorsal view fused basally with segment IX, posteriorly sinuate on lateral margin and tapering to rounded apex. Subgenital plate in lateral view narrow basally, ventral margin with large sclerotized lobe at midlength, upper margin straight distally, abruptly tapered posteriorly to rounded apex bearing stout seta; in ventral view wide and rounded laterally to truncate apex, with setae laterally. Bracteole in lateral view parallel-sided to rounded apex; in ventral and dorsal views straight, narrow over length. Inferior appendage triangular and sclerotized; in ventral view divergent, lateral margin curving, inner margin straight, round lobe at midlength, basally with elaborate thin sclerites. Phallus in dorsal view tubular, bearing short paramere encircling shaft at midlength, apex rectangular with ejaculatory duct protruding mesally.

Distribution.

Panama: Veraguas Province (Santa Fe National Park).
