The pollinosa  Group

Diagnosis. Specimens of this species-group are similar to those of the paniculata  group but may be distinguished by the following combination of character states:

Head: Frons narrower, width at level of medial ocellus about 2 × distance between ptilinal suture and medial ocellus; arrangement of ocelli distinctly forming isosceles triangle, distance between posterior pair much larger than between either posterior ocellus and medial one; lateral vertical seta well developed, subequal to medial vertical seta; smaller fronto-orbital setae much less than 1 / 4 larger lateroclinate setae, lacking a larger anterior pair of setae; arista macropubescent along most of length; interfoveal hump poorly developed, lacking a distinct dorsal crease; face between oral margin and dorsum of interfoveal hump shorter, length about equal to larger setae along oral margin; coloration of face whitish gray, contrasting distinctly with brownish coloration of frons.

Thorax: Mesonotum subshiny to shiny, microtomentose vestiture sparse, not contrasting distinctly with appearance of scutellum; larger acrostichal setae not extended posteriorly much past level of transverse suture; postpronotum bearing 2–3 setae; scutellum flat and very sparsely setulose; dorsocentral setae 4–5 (1 + 3; 2 + 3); postsutural, supra-alar seta either lacking or much reduced; coloration of pleural areas becoming gradually grayer toward venter, but lacking patches of contrasted coloration; wing appearing dull, infuscate; 2 white spots on either side of crossvein dm-cu; legs black; fore- and hindfemur swollen.

Abdomen: Color blackish, shiny; tergite 5 as long or longer than tergite 4; male tergite 4 subequal to combined length of tergites 2 and 3; surstylus of male terminalia fused to ventral margin of epandrium but distinct, setose; aedeagus produced ventrally as 2 symmetrical narrow processes; gonite produced anteroventrally as curved parallel-sided slender process.
