Diagnosis.

Neotrichia parajarochita sp. nov. is another member of the N. canixa group of Keth et al. (2015) based on the posterior horns from tergum X, forked bracteole, and the forked apex of the phallus. In many respects, the new species appears to be similar to N. jarochita Bueno-Soria, 1999 and N. palitla Harris & Flint, 2016, both of which occur in Mexico, on the basis of the asymmetrical horns of tergum X and the structure of the bracteole. Unlike these two species, N. parajarochita has a sclerotized posterolateral process from segment IX and the inferior appendages are divergent in ventral view.

Description.

Male. Total length 1.4 mm (n = 1), 18 antennal segments, wings and body brown in alcohol. Genitalia (Fig. 12 ). Abdominal segment VIII annular. Segment IX in lateral view ovate, rounded anteriorly and sinuate posteriorly, setae-bearing lobe dorsally and fused with segment X, with upturned posterolateral process mesally, narrowing distally to serrate apex; in ventral view anterior margin emarginate, posterior margin incised mesally, with an oval mesal extension, and posterolateral processes laterad, narrow over length and curving. Tergum X basally fused with segment IX, quadrate, posterior horns asymmetrical, left horn twice as long as right; in lateral view segment X is truncated, distal horn elongate and tapering to acute apex. Subgenital plate in lateral view, wide basally, tapering distally to acute apex, which is slightly downturned; in ventral view roundly triangular, abruptly narrowed distally forming rectangular mesal extension flanked by pair of setae. Bracteole in lateral view wide anteriorly, bifid posteriorly, thin dorsal branch slightly longer than triangular ventral branch, each tipped with seta; in ventral and dorsal views wide basally, tapering distally. Inferior appendage short in lateral view, widening at midlength, then tapering to rounded apex; in ventral view bifid, outer process wide basally, narrowing distally and strongly diverging, rectangular apically with lateral spike, inner process shorter and narrower than outer process. Phallus tubular, constricted at midlength and bearing thin paramere encircling shaft, apex forked, lower fork strongly curving, ejaculatory duct protruding subapically.

Distribution.

Panama: Chiriquí Province (Parque International La Amistad).

Etymology.

This species is named for its resemblance to Neotrichia jarochita . The name is an adjective used as a substantive in the genitive case.
