Diagnosis. Oxyethira buenoi is most similar to Oxyethira quinquaginta Kelley and O. sierruca Holzenthal and Harris on the basis of the many segmented antennae, the vestigial inferior appendages and the asymmetrical arms of the subgenital plate. The new species is separated by the acute tapering of abdominal segment VIII and the configurations of the subgenital plate and the phallus.

Male. Length 2.6 mm. 43 antennal segments, brown in alcohol. Abdominal segment VII tapering ventrad in lateral view, elongate ventral process. Segment VIII in lateral view elongate, posteriorly tapering to acute apex; in dorsal and ventral views deeply convex posteriorly, laterally tapering to angled apices, truncate anteriorly. Segment IX retracted into segments VI, VII, and VIII, in lateral view tapering anteriorly, posteriorly truncate; in dorsal and ventral views, rounded anteriorly, posteriorly reduced to a thin band. Segment X and inferior appendages vestigial. Subgenital plate reduced to a narrow band in lateral view, with pair of asymmetrical posterior arms, ventral arm thick, with acute apical point, dorsal arm thin and upturned distally; in dorsal view, left arm widening distally with margin slightly concave, with lateral sclerotized spot; right arm nearly uniform in width, boot-shaped apically. Phallus in dorsal view widening distally and divided into pair of elongate rods, right rod sinuate, tapering apically, left rod straight, tapering distally; in lateral view inner rod curving upward to rounded apex, outer rod nearly parallel-sided and tapering to acute, slightly upturned apex.

Female. Unknown.
