Diagnosis.

Neotrichia abrebotella sp. nov. appears to be a member of the N. caxima group of Keth et al. (2015) based on the short inferior appendage with resemblance to N. atopa Thomson & Armitage, 2018 and N. caxima Mosely, 1937. It differs from N. caxima in the lack of sclerotized phallic processes and from N. atopa in the bifid appearance of the inferior appendage in lateral view and the narrow bracteole.

Description.

Male. Total length 1.7-1.9 mm (n = 3), 18 antennal segments, wings and body brown in alcohol. Genitalia (Fig. 2 ). Abdominal segment VIII annular. Segment IX in lateral view rounded posteriorly, narrowing dorsally, anteriorly narrowing to elongate mesal apodeme; in dorsal and ventral views quadrate, deeply incised anteriorly. Tergum X short, truncate posteriorly, tapering on lateral margins; in lateral view truncate posteriorly. Subgenital plate in lateral view wide subapically, narrowing distally to rugose, downward projecting process; in ventral view wide, truncate posteriorly with median lobe and pair of stout setae, rounded on lateral margins. Bracteole narrow basally, slightly widening distally; in dorsal and ventral views lobate. Inferior appendage short and narrow, bifid posteriorly, lower portion longer than upper; in ventral view square basally, distally bifid, dorsalmost process narrowing mesally to acute apex, ventralmost process tubular. Phallus tubular, wide basally, constricted at midlength and bearing thin paramere encircling shaft, apically thin over length.

Distribution.

Panama: Chiriquí Province (Reserva Privada Landis).

Etymology.

The species name Neotrichia abrebotella (bottle-opener) derives from Spanish, referring to the distinctive appearance of the inferior appendage. The name is a noun in the nominative singular standing in apposition.
