Head . Face usually dark dorsal to tubercle; tubercle pointed and medially positioned ( Fig. 5 ). Frons dark. Frons/frontal triangle rugose ( Fig. 4 ). Frontal triangle with white microtrichosity concentrated laterally along eye margin ( Fig. 83 ). Female ocellar triangle separated by less than its length from posterior eye margin ( Fig. 1 ). Occiput microtrichia homogeneously distributed ( Fig. 5 ). Thorax . Scutum dull pale-microtrichose with sub-median pair of weak white microtrichose patches on anterior region, sometimes with weak stripes in place of patches ( Fig. 1 ). Scutellum pale. Post-metacoxal bridge almost complete ( Fig. 79 ). Metafemur pale. Wing . Female wing hyaline; female wing bare on basal 1/4 (or almost the whole cell) of cell c, basal 1/3 to 1/2 of br, and baso-anterior margin of bm. Terminalia . Male epandrium enlarged; hypandrium reduced; *surstylus quadrangular with filiform apical extension ( Fig. 7 ); *subepandrial sclerite with strongly sclerotized rectangular middle area and wide, but weakly sclerotized, ventrally directed lateral expansions ( Fig. 9 ); *hypandrium oval ( Fig. 11 ), much smaller than epandrium; postgonite elongated ( Figs 10, 11 ). Included species (11): F . argentina ( Curran, 1939 ) comb. nov. [1b], F . deceptor ( Curran, 1930a ) comb. nov. [1b], F . filiola ( Shannon, 1927 ) comb. nov. [2], F . harlequina ( Hull, 1948 ) comb. nov. [1b, 1c], F . hyacinthia ( Hull, 1947a ) comb. nov. [2], F . mara ( Curran, 1941 ) comb. nov. [1b], F . oenone ( Hull, 1949a ) comb. nov. [2, type lost], F . provocans ( Curran, 1939 ) comb. nov. [1b], F . rugosifrons ( Schiner, 1868 ) , comb. nov. [2, 3, 4], F . stenogaster ( Williston, 1888 ) comb. nov. [1b], F . zephyrea ( Hull, 1947b ) comb. nov. [1b]. Comments. The rugose frons/frontal triangle is a distinct character of this group ( Fig. 4 ), but not unique since it occurs in the Pelecinobaccha brevipennis species group as well. Further distinct characters for the F. rugosifrons group include the face that is dark dorsal to tubercle, the pointed and medially positioned facial tubercle ( Fig. 5 ), the entirely pale scutellum, the almost complete post-metacoxal bridge ( Fig. 79 ), the enlarged epandrium ( Fig. 7 ), and the reduced hypandrium ( Fig. 10 ).
