Diagnosis.

On the basis of the tripartite inferior appendage, this species is placed in the Zumatrichia galtena group of Flint (1970), showing similarity to Z. attenuata Flint, Z. dereka Oláh & Flint, and Z. flinti Harris & Armitage all of which occur in Panama. It differs from these species in the structure of the inferior appendage and the phallus, which has a distinctive sinuate dorsal rod, not seen in the other species.

Description.

Male. Total length 4.5-5.5 mm, 19 antennal segments with scape enlarged, wings dark brown with while diagonal band near forewing midlength, body brown in alcohol. Genitalia. Abdominal segment VII annular with ventromesal process. Segment VIII in lateral view truncate posteriorly, tapering anterodorsally; in dorsal view with deep, broad emargination, anteriorly; in ventral view with broad posterior incision, narrowing anteriorly. Segment IX generally quadrate in lateral view, narrowing anteriorly, posterior margin with dorsal lobe, elongate setal-bearing process posteroventrally, mesal incision on posterior margin; dorsally emarginated on posterior and anterior margins. Segment X rectanguloid in lateral aspect, distally bifid and membranous; in dorsal view triangular. Inferior appendage tripartite, dorsalmost process angled dorsally then thin and elongate, with subapical ventral process, medial process thin and acute distally, ventralmost process rectangular, truncate distally; in ventral view this ventralmost process is truncate posteriorly with numerous setae, incised on lateral margins and serrate. Penal sheath with subapical point in lateral view; phallus with medial ring-like structure, posteriorly with pair of elongate ventral spines, dorsally with sinuate process which ends in small incisions; in dorsal view this thin sinuate process extends from the ring-like structure to the phallic apex.

Distribution.

Panama.

Etymology.

The species name Zumatrichia culebra (snake) derives from Spanish, referring to the sinuate dorsal rod of the phallus.
