Fig. 20

Diagnosis. Based on the divided tenth tergum, this species is placed in the O. aldama group of Flint (1972), with some similarity to O. avis Bueno-Soria and Holzenthal , O. bicaudata Bueno-Soria and Santiago-Fragoso , and O. quebrada Bueno-Soria and Holzenthal. The new species is separated on the basis of the spinose left side of the tenth tergum, which has a basal process, and the thin, elongate right side of the tergum.

Male. Length 2.0 mm, antennae broken, brown in alcohol. Abdominal segment VII and VIII annular, the former with short posteroventral process. Segment IX in lateral view posteriorly sinuate, tapering anterodorsally; square ventrally, rounded anteriorly, sinuate posteriorly; dorsally incomplete. Tergum X divided into three processes, two of which are elongate, right side process narrow over length, twisting inward subapically, left process widening subapically, apex divided into several sharp spines, base of left side with thin process tapering apically; in lateral view, upper process, thin and elongate, lower process thicker with bifid apex. Inferior appendages in lateral view thin and elongate, widening near midlength, apex rounded, numerous peglike setae on inner posterior and ventral margin; in dorsal and ventral views narrow, gradually tapering to acute apex, numerous peglike setae on mesal margins. Phallus thin and elongate, apically with pair of small lobes.

Female. Unknown.

Type material. Holotype, male— Panama, Bocas del Toro Province, tributary of Quebrada Rambala at 2 nd footbridge, Rambala Jungle Lodge , 8.91627°N and 82.15469°W, 134 m, March 28, 2015, E. Carlson.

Etymology. We take great pleasure in naming this species for our colleague Dr. Boris C. Kondratieff, Director of the C.P. Gillette Museum of Arthropod Diversity, Colorado State University, in recognition of his lifetime of work on aquatic insects in the Neotropics.
