Male: length 0.58-0.83mm.

Legs generally slightly darker than those of female with brown areas more extensive and more poorly defined, fore coxa orange-brown; head about 1.9X as wide as frontovertex, ocelli forming an angle of about 95°; antenna ( Fig. 217) with all funicle segments longer than broad, F1 slightly longer than broad, F6 about 2X as long as broad, all segments clothed with whorls of long setae, dorsal ones longest and at least about 5X as long as diameter of segments; frontovertex less metallic than in female with conspicuous, polygonally reticulate sculpture of mesh size similar to eye facet; phallobase ( Fig. 218) about 3.3X as long as broad; with each digitus about 3.5X as long a broad and with two apical hooks, aedeagus about 7X as long as broad, apically acute and about 0.5X as long as mid tibia.

COMMENTS. Coccidencyrtus umbro and cyathus are probably the most similar Costa Rican species to annulipes (Blanchard) or maculicornis (Blanchard) from Argentina. They both differ from either of the Argentinian species by having the sculpture of the mesoscutum longitudinally strigose to striate reticulate and similar to that of the scutellum whereas in annulipes and maculicornis the sculpture on the mesoscutum is imbricate or squamiform.
