Type material.

Holotype: ♂, Panama: Chiriquí Province: Cuenca 108, Boquete District, Quebrada Honda, N Fortuna Dam, Fortuna Forest Reserve; 8.74985°N, 82.23885°W; 1132 m a.s.l.; 18.ii.2018; B. Armitage, T. Arefina-Armitage leg.; UV light trap; MUPADI-007-T-2023 (in alcohol).

Diagnosis.

Neotrichia honda sp. nov. does not fit well in any of the species groupings established by Keth et al. (2015). The new species has forked sclerites at the apex of the phallus and has an overall resemblance to N. gilaensis Keth et al., 2015 from Arizona which is in the N. collata group, but it is also similar to N. yavesia Bueno-Soria, 2010 from Mexico in the N. vibrans group, based on the short, rectangular inferior appendages. The new species is separated by the elongate, forked sclerites of the phallus apex, the elongate anterior apodeme of segment IX, and by the sclerotized posterolateral processes from segment IX.

Description.

Male. Total length 1.5 mm (n = 1), 18 antennal segments, wings and body brown in alcohol. Genitalia (Fig. 7 ). Abdominal segment VIII annular. Segment IX in lateral view anteriorly tapering to elongate apodeme, posteriorly rounded with posterolateral process, which is wide basally, tapering distally to an acute downward turning hook; dorsally and ventrally deeply incised anteriorly, ventrally with deep lateral incisions posteriorly, creating an elongate mesal, triangular lobe; dorsally with posterolateral processes narrow over length, curving slightly inward apically. Segment X elongate and thin in lateral view; in dorsal view wide basally and fused with segment IX, tapering to rounded apex. Subgenital plate in lateral view, wide basally, gradually tapering apically to rounded apex bearing elongate seta; in ventral view narrowly triangular, pair of stout setae apically. Bracteole in lateral view wide basally, then narrowing distally to truncate apex; in ventral and dorsal views narrow over length and curving mesally. Inferior appendage sclerotized and rectangular, wide basally, narrowing at midlength, then abruptly tapering to rounded apex; in ventral view triangular, rounded apically, basally with finger-like lobe. Phallus in dorsal view wide basally, bearing short paramere encircling shaft at midlength, apex divided into pair of elongate, sclerotized rods, which are nearly equal in length.

Distribution.

Panama: Chiriquí Province (Fortuna Forest Reserve).

Etymology.

This species is named for Quebrada Honda, a tributary of Río Chiriquí and Fortuna Reservoir in northeast Chiriquí Province, where the species was collected. The name is a noun in the genitive case.
