Material examined (12 males, 10 females) NICARAGUA: Granada, Volcán Mombacho, El Progreso, malaise trap, 2 June 1998, Col. J. M. Maes, 7 males, 4 females (MELN, MXAL); Volcán Mombacho, Santa Ana, 30 June 1998, Cols. J. M. Maes, 5 males, 6 females (MELN, MXAL).

Biology. This species inhabits cloud forests and coffee plantations located at altitudes from 800 to 1500 m. Month of collection: June (22).

Distribution. Southern Nicaragua (12° 10'– 13° 05' N, 84° 40' – 86° 10' W).
