Distribution. Dominican Republic: Azua, Independencia, La Altagracia, La Romana, La Vega, San Juan, Santiago, and Santo Domingo provinces. Active at 12 to 1239 meters in elevation during April through August, and into November.

Etymology. This species is named for Norman Woodley, USDA, SEL, at the NMNH, Washington, D.C., who collected the holotype of this species and contributed numerous specimens from the Dominican Republic during our study.

Remarks. Efferia woodleyi  is distinguished by the abundant black vestiture of the head; black pronotal bristles, and combined characters of the terminalia ( Figs. 82–87View FIGURES 82–87). The male is further distinguished by slightly dilated costa, R4 recurrent vein usually absent, and segments 5–7 or 6–7 white tomentose. The female is further distinguished by the brownish-gray tomentose and white setose sternite 7, only the apical margin has black setae, setae sometimes entirely white, and the long slender ovipositor.
