Type specimen.

Holotype: male, Panama: Veraguas Province: Cuenca 097; Santa Fe District; Santa Fe NP; Río Calovébora; PSPSCB-NPSF-C-097-2017-005; 8.54318°N, 81.16398°W; 536 m a.s.l.; Malaise trap; T. Ríos, E. Álvarez, C. Nieto, leg.; 19-23.iv.2017; MIUP-013-T-2023 (in alcohol).

Diagnosis.

This unusual species with a large, flap-like inferior appendage is most similar to O. unica Bueno-Soria & Santiago-Fragoso from Columbia and O. legeza Oláh & Johanson from Peru, which are similar in the lateral aspect. It differs in the size of the lateral process of the inferior appendage, the structure of tergum X, and the angled phallic apex.

Description.

Male. Total length 3.0 mm, antennae long with 38 antennal segments, wings and body brown in alcohol. Genitalia. Abdominal segment VII annular with short ventromesal process. Segment VIII in lateral view wide dorsally, tapering ventrad on posterior margin; quadrate in dorsal view. Segment IX rectangular in lateral view, incomplete dorsally sinuate posteriorly; in ventral view reduced dorsally, tapering anteriorly; in dorsal view incised on lateral margins. Segment X triangular in lateral view, with sclerotized dorsal plate; in dorsal view triangular, thin, sclerotized, mesal rod with lateral spike apically. Inferior appendage in lateral view narrow at base, widening at midlength and bearing numerous peg-like setae on inner margin, then angled dorsad and tapering distally to rounded apex, large lobe on inner surface subapically; in ventral and dorsal views, narrow basally, greatly widening distally and turning inward, apices overlapping, numerous peg-like setae on lateral margins. Phallus in dorsal view thin over length, but wider basally, apex angled forming short spike.

Distribution.

Panama.

Etymology.

The species name Ochrotrichia conejoreja (rabbit-eared) derives from Spanish, referring to the inferior appendage, which reminded the authors of a rabbit ear.
