Etymology. The specific epithet “ woodruffi ” is in in honor of the late Robert “Bob” E. Woodruff, Gainesville, Florida, who collected much scientific material in the Dominican Republic during his numerous visits, including many of the first specimens known of this species.

Distribution. Island of Hispaniola, Dominican Republic, and Barahona, Independencia, Pedernales provinces.

Notes. The collecting site for the largest series of this species was among “old coffee groves neighboring virgin forests” at approximately 1000 m elevation (P. Skelley, pers. comm.). Other specimens were collected at remnant mesic forest sites in ravines, or in primary or older secondary forests. Adults were obtained at night by lights and during daylight periods by gleaning, beating, or sweeping vegetation, especially along trails and at forest edges and openings.
