Diagnosis.

Neotrichia panamensis 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 bifid inferior appendage. The new species appears to be similar to N. alsa Oláh & Johanson, 2011 from Peru on the basis of the bracteoles and phallic apex, but the short inferior appendages are more like those of N. tauricornis Malicky, 1980 which occurs throughout the Caribbean islands, Panama, and Colombia, but the subgenital plate and bracteoles are much different in the new species compared to that of N. tauricornis .

Description.

Male. Total length 1.5-1.7 mm (n = 14), 18 antennal segments, wings and body brown in alcohol. Genitalia (Fig. 11 ). Abdominal segment VIII annular. Segment IX in lateral view ovate, rounded anteriorly and sinuate posteriorly, fused with segment X dorsally, bearing a setae-bearing lobe dorsally; in ventral view anterior margin deeply incised, posterior margin sinuate, triangular mesal extension. Tergum X basally fused with segment IX, rectangular basally, pair of thin, symmetrical horns distally; in lateral view segment X is lobate, with distal horn saber-like. Subgenital plate in lateral view, wide basally, truncate distally with ventral hook tapering to acute apex; in ventral view wide basally, slightly curving to rounded apex, with mesal process flanked by stout setae. Bracteole in lateral view wide anteriorly, slightly bifid posteriorly, dorsal branch elongate and tipped with seta, ventral branch vestigial, represented by pair of sharp points; in ventral and dorsal views lower branch represented by short knob, tapering distally. Inferior appendage short and bifid, wide basally tapering distally, basal process triangular; in ventral view bifid, outer process subrectangular, apex with mesal points, inner process same length as outer, fused and wide at base, tapering distally bearing elongate seta apically. Phallus tubular, constricted at midlength and bearing thin paramere encircling shaft, apex divided into three processes, lower process small, distally processes elongate, ejaculatory duct not protruding at base.

Distribution.

Panama: Colon Province (Portobelo District); Veraguas Province (Las Palmas District).
