Diagnosis.

Neotrichia landisae sp. nov. belongs to a cluster of similar Panamanian species with characteristic elongate posterolateral processes from abdominal segment IX, including N. tatianae Armitage & Harris, 2018 and N. yayas Armitage & Harris, 2020. The new species is separated from these species by the linear posterolateral processes from segment IX, the truncate inferior appendage, and the narrow subgenital plate in ventral view.

Description.

Male. Total length 1.5-1.7 mm (n = 15), 18 antennal segments, wings and body brown in alcohol. Genitalia (Fig. 8 View Figure 8 ). Abdominal segment VIII annular. Segment IX in lateral view anteriorly rounded, wide posteroventrally, narrowing dorsally, pair of elongate, thin posterolateral processes, which narrow distally; in dorsal view fused posteriorly with segment X, pair of small setaceous lobes laterally, posterolateral processes sclerotized and elongate, but dissimilar in length, anteriorly with narrow mesal incision; in ventral view with deep lateral incisions. Tergum X basally fused with segment IX, posteriorly elongate, tapering to rounded mesal lobe; in lateral view wide basally, tapering distally to acute apex. Subgenital plate in lateral view wide basally, tapering distally to narrow shelf bearing stout seta; in ventral view narrow over length, pair of setae apically. Bracteole absent or represented by thin, elongate seta-bearing process on dorsal margin of segment IX. Inferior appendage short, wide basally, widening subapically, spinose and rugose on distal margin, thin ventral process basally; in ventral view elongate and narrow, apical point turning inward, spinose subapically on mesal margin, base of inferior appendage and processes from segment IX superimposed, short triangular mesal process bearing stout seta apically. Phallus tubular, constricted at midlength and bearing thin paramere encircling shaft, apically rounded with ejaculatory duct protruding.

Distribution.

Panama: Chiriquí Province (Reserva Privada Landis, Finca La Esperanza).

Etymology.

This species is named for Senora Marietta Isabel Landis, owner of Reserva Privada Landis, who managed all collection events. The name is a noun in the genitive case.
