Efferia bellardii n. sp.

Fig. 1 , 5-7, 50

Description. Male. Body blackish, 14.7-15.0 mm; wing 10.6-10.8 mm. Head: Yellowish or yellowish-gray tomentose. Mystax mostly black medially, mixed with yellow setae, sparse black bristles along oral margin laterally. Palpi black setose on apical 1/3-1/2, yellowish basally. Proboscis yellowish setose. Antenna, frons, ocellar tubercle black setose; scape twice as long as pedicel; flagellum and style absent; face at antenna and frons at ocellar tubercle about same width. Ocellar setae longer than 3 antennal segments combined. Occiput yellowish-gray tomentose, yellowish setose; 5 black postocular bristles and sparse black setae dorsally.

Thorax: Black, mostly yellow tomentose, vestiture mostly black. Pronotal bristles all black or mixed yellow and black, as long as postocular bristles. Scutum yellow tomentose, yellowish-gray posteriorly; anterior setae as long as or slightly longer than scape and pedicel combined; lateral bristles stout, dorsocentrals thinner and shorter, longest posteriorly, acrostichal setae abundant, about as long as dorsocentrals posteriorly. Scutellum yellowish-gray tomentose, mostly or entirely black setose, sparse yellow setae mixed, longer than scape and pedicel combined; 6 thin marginal bristles, 2-3 slightly stout. Pleura mostly brownish-yellow tomentose, paler posteriorly; vestiture mostly black, mixed yellow and black, or sparse posteriorly. Halter dull brownish-yellow, knob sometimes darker.

Wing: Costal margin only slightly dilated; cells on apical 1/2 brownish, costal cell brown. R 4 slightly oblique, recurrent vein about as long as cell base. Crossvein r-m just before apical 1/4 of cell d.

Legs: Mostly yellow setose, dorsal 1/2-2/3 of femora black setose, metathoracic femora mostly Figure 5-7.

Abdomen: Wide sides of tergites 1-5, sternites 1-5, segments 6-7 white tomentose, tergites 1-5 brown dorsally; setae mostly yellowish, long on segments 1-3 and sternite 4; short, brown setae on tergites 4-5 dorsally, tergite 8; apical margins of sternites 7-8 white setose. Hypandrium dark brown.

Terminalia (Fig. 5-7): Black, mostly black setose. Epandrium twice as long as wide, wide apically with triangular posterodorsal flange. Gonostylus clavate apically, with pointed apex. Phallus narrow, flange small; aedeagus with dorsal prong longer than ventral tubes. Gonocoxite acuminate apically; setae long, dense.

Female. Unknown.

Etymology. The species name, bellardii , lateral views; 8. intact terminalia; 9. gonostylus; 10a-b. genitive case, recognizes the Italian dipterist Luigi phallus with aedeagus, aedeagal tubes, and phallic Bellardi for his contributions on the Neotropical flanges. asilid fauna.

Remark. Efferia bellardii runs to Ef. rufitibia in Bromley’s (1929) key. The mostly black vestiture of the mystax, palpi, antenna, frons, and ocellar tubercle, the black scutellar setae and 6 black marginal scutellar bristles, blackish tarsi, and characters of the male terminalia (Fig. 5-7) distinguish this species from congeners. The dilated costal margin, the long anterior scutal and scutellar setae, and the long, dense, black setae on the gonocoxite are diagnostic of the male.
