Proboscis white setose. Antennae with scape or flagellum twice as long as pedicel; 3 antennal segments as long as style. Frons brownish-yellow; vertex above ocellar tubercle only slightly narrower than face at antennae or frons at ocellar tubercle. Ocellar setae as long as 3 antennal segments combined. Occiput yellowish-gray dorsally, gray ventrally; setae mostly white, black dorsally, black postocular setae extend to mid-lateral margin of head; 4-5 thin, black postocular bristles dorsally.

Thorax: Pronotum yellow or brownish-yellow Figure 40-42. Male terminalia of Efferia pina n. sp,

tomentose, setae mostly black, bristles absent. lateral views; 40. intact terminalia; 41. gonostylus; 42a- Scutum brownish-yellow anteriorly, yellowish- b. phallus with aedeagus, aedeagal tubes, and phallic gray posteriorly; vestiture black, anterior setae flanges. as long as scape and pedicel combined; dorsocentrals seta-like, long posteriorly; lateral bristles thicker and longer. Scutellum yellowish-gray tomentose, black setose, as long as or slightly longer than scape; 10-12 long, thin, black marginal bristles. Pleura brownish-yellow or yellow tomentose; vestiture mostly black. Halter knob reddish, stalk pale yellow.

Wing: Brownish, especially dark bordering veins; costal cell darker brown.

Legs: Coxae mixed black and white setose. Femora mostly black setose, setae yellow posteriorly and

ventrally; bristles black. Tibiae mostly pale reddish-yellow, black apically; bristles and long setae black; dense, short, reddish-yellow setae on tibiae and tarsi ventrally. Tarsi black or reddish-black, bristles and setae black dorsally.

Abdomen: Tergites 1-7 brown tomentose with brown setae dorsally, wide sides white tomentose with

short white setae, setae longer and yellowish on basal 3 tergites; sternites 1-7 mostly white tomentose with short, white, erect setae, those on basal 3-4 sternites longer; sternite 7 mostly black setose, long setae apically.

Terminalia (Fig. 39): Black, 6.3 mm; at middle 1/12 as wide as long, longer that segments 5-7; base

Remark. The large body [19 mm]; mostly or entirely black vestiture of the head and thorax; long ocellar, anterior scutal and scutellar setae; 10-12 thin black marginal bristles; prothoracic and mesothoracic coxae mixed black and white setose, and terminalia longer than segments 5-7 and wide base ventrally with dense tuft of black setae (Fig. 39) distinguish E. pilosula from congeners.
