Gonocoxa with pointed apex slightly concave anteriorly; setae short, sparse, light brown, pale, or mixed.

Female. Measurements, body 8.7–10.7 mm; wing 6.1–8.1 mm. Head: Frons and antennae sometimes entirely black setose. Wing: R4 recurrent vein about 2/3 diameter of r4 basally. Abdomen: Wide sides of tergites 1–7 and sternites 1–7 entirely whitish tomentose; setae mostly white, those on sternites 1–4 long, erect, much shorter on 5–7. Tergites 1–7 mostly brownish-yellow or brown tomentose, setae mostly brown, latter sparse on basal 2–3 tergites, more abundant, widely distributed on 4–7; segment 7 entirely tomentose. Terminalia ( Figs. 13–14View FIGURES 9–14): Length 2.1–3.7 mm, 5.7–7.9 times longer than diameter at middle medially. Cercus about 1/3 as long as tergite 7 dorsally. Spermathecae oval, apex rounded.

Distribution. Dominican Republic: Barahona, Isla Beata and Pedernales provinces. Active at sea level to 730 m during April, July, August, October, and December.

Etymology. Latin bullata  refers to the enlarged terminalia of the species.

Remarks. Efferia bullata  is distinguished by its size [8.7–10.7 mm], brownish tomentum and mostly white setae of the head, scutellum, and abdomen, anterior scutal setae are about as long as the scape, scutellar setae as long or longer than the scape and pedicel combined, and combined characters of the terminalia ( Figs. 9–14View FIGURES 9–14). The male is further distinguished by the extremely short R4 recurrent vein, absence of a costal dilation, segments 6–7 entirely white tomentose, the strongly inflated terminalia which is about twice as wide apically as basally, epandrium twice as long as wide, and gonocoxa with sparse, short, mostly brown, setae. The female is further distinguished by the entirely tomentose segment 7 and short terminalia [2.1–3.7 mm].
