Diagnosis.
This species is a member of the Oxyethira aeola group of the subgenus Oxyethira Oxytrichia , with closest similarity to O. apinolada Holzenthal & Harris. It differs from this species, which occurs in Panama and neighboring Costa Rica, in the ear-like appearance of the subgenital plate in dorsal view, the distinct presence of segment X, and the prominent bilobed process which is absent or indistinct in O. apinolada .
Description.
Male. Total length 2.5 mm, 27 antennal segments, wings and body brown in alcohol. Genitalia. Abdominal segment VII annular, with short ventromesal process. Segment VIII with prominent, dorsoapical shelf, margin straight ventrad; in dorsal view, broadly incised posteriorly; in ventral view with deep, V-shaped mesal incision. Segment IX largely contained within VIII, tapering anteriorly into segment VII, posteriorly with narrow, shelf-like lobe. Segment X membranous, extending slightly beyond segment VIII in lateral view. Inferior appendage in lateral view narrow, apex rounded; in ventral view with pair of rounded lobes adjacent to triangular mesal lobe. Subgenital plate tapering distally to acute apex; in ventral view narrow, curving outward to acute apices; in dorsal view, falcate, bent sharply at midlength to acute apices. Bilobed process elongate laterally, wide basally tapering posteriorly and bearing an elongate seta; in dorsal and ventral views narrow over length. Phallus wide basally and apically, apex with heavily sclerotized spine nearly encircling shaft.
Distribution.
Panama.
Etymology.
This species is named for Dr Dale-Elizabeth Pehrsson, former President of the Pennsylvania Western University, which includes Clarion University, in recognition of her leadership and support of scholarship at these institutions.
