Type material.

Holotype: ♂, Panama: Darién Province: Cuenca 156, Pinogana District, Darién NP, Río Pirre, Estacion de MiAmbiente en Rancho Frio; 8.09081°N, 77.74043°W; 73 m a.s.l.; 9-12.ii.2018; A. Thurman leg.; Malaise trap; MUPADI-011-T-2023 (in alcohol).

Diagnosis.

Neotrichia mindyae sp. nov. is another member of the N. canixa group of Keth et al. (2015) based on the posterior horns from tergum X, forked bracteoles, and the bifid inferior appendage. The new species appears to be most similar to N. maya Harris & Flint, 2016 from Belize on the basis of the structure of the bracteole and the horns of tergum X. The new species is separated by the structure of the phallic apex, which while forked, has the one process extremely long, similar to that of N. maria Bueno-Soria & Hamilton, 1986 from Mexico, and by the unequal forking of the bracteole, which are uniformly forked in N. maria .

Description.

Male. Total length 1.5 mm (n = 1), 18 antennal segments, wings and body brown in alcohol. Genitalia (Fig. 10 ). Abdominal segment VIII annular. Segment IX in lateral view generally ovate, rounded anteriorly and posteriorly, fused with segment X dorsally, and bearing lateral setal lobes posteriorly; in ventral view anterior margin deeply incised, posterior margin with triangular mesal extension; in dorsal view with pair of posterolateral lobes. Tergum X basally fused with segment IX, posteriorly produced into pair of thick, symmetrical horns which nearly touch mesally; in lateral view distal horns are thin and tapering to acute apices. Subgenital plate in lateral view, wide basally, tapering distally to downturned apical hook; in ventral view wide basally, rounded laterally to apicomesal extension. Bracteole in lateral view wide anteriorly, bifid posteriorly, dorsal branch elongate with apical seta, ventral branch greatly reduced with apical seta; in ventral and dorsal views both branches wide basally, tapering to rounded apices. Inferior appendage bifid laterally, each thin arm wide basally and tapering distally to rounded apices bearing long seta; in ventral view bifid, outer process wide basally, curving and tapering to acute apices, inner process fused basally and narrow over length which is equal to outer process bearing elongate seta apically. Phallus tubular, wide basally, constricted at midlength and bearing thin paramere encircling shaft, apex with elongate lateral spike, smaller spike near base, ejaculatory duct not protruding.

Distribution.

Panama: Darién Province ( Darién National Park).

Etymology.

This species is named for the sister of the first author, Melinda “Mindy” Harris Haupt, who used to help her brother collect bugs when they were both much younger. The name is a noun in the genitive case.
