DIAGNOSIS. — Frons ( Fig. 1B View FIG ) yellow or ochreous laterally, darkened centrally on ventral half and on ocellar tubercle, with two spots of silvery pruinosity lateral to ocellar triangle, and fine yellow pilosity; face brown with one yellow V-shaped spot on ventral half, below facial tubercle; scutum brown with acrostichal and dorsocentral stripes of pale golden pruinosity; pleura lacking horizontal stripe of silvery pruinescence on anepisternum (present in R. tibialis   ); wing ( Fig. 1F View FIG ) hyaline with brown spots; mid tibia with ventroapical short, wide, spur-shaped process in males; hind tibia with tubercles on dorsal surface; tergites dark brown, with four spots of silvery pruinosity arranged in a checkerboard pattern; postgonites bilobate, phallus lacking lateral projections; dorsal process of hypandrial arms curved, with basal half perpendicular to basal region, apex rounded with short lateral branches.

COMMENTS

Together with R. nudipes Frey, 1959   and R. stictica Wiedemann, 1830   , R. clavipes   belongs to a species group with distinctly infuscated wings. It differs from R. stictica   by the size of the wing spots, which are larger in R. clavipes   , and from R. nudipes   by the number and sharpness of the spots, which are more distinct and numerous in R. clavipes   . Furthermore, R. clavipes   differs by features of the male genitalia as follows: surstylus straight (falciform in R. nudipes   ) and anchor-shaped dorsal process of hypandrial arms with short branches (long branches in R. nudipes   and R. stictica   ). Ropalomera clavipes   was revised by Kirst & Ale-Rocha (2012).
