Originally described from Brazil; new records from Peru are given below.

Material examined (8): Peru: Madre de Dios, Rio Tambopata Res ; 30 air km SW Pto. Maldonado, elev. 290 m (13°0’S, 69°33’W), 2–5.xi.1979, leg. J. B. Heppner (1 NMNH); GoogleMaps same locality, 6–10.xi.1979, leg. J. B. Heppner (3 NMNH); GoogleMaps same locality, 16–20.xi.1979, leg. J. B.

Heppner (1 NMNH); GoogleMaps Tambopata, Madre de Dios, 15km NE Puerto Maldonado, Reserva Cuzco Amazonico , elev. 200 m (12°33’S, 69°3’W), 9.vi.1989, leg. J. S. Ashe, R. A. Leschen (009) (1 SEMC); GoogleMaps same locality, 14.vi.1989, leg. J. S. Ashe, R. A. Leschen (180) (1 SEMC) GoogleMaps .

Remarks. I have examined the holotype, including the male genitalia, of H. coeneni (RBINS) . The male genitalia has the tips of the parameres sheared off—by a previous worker. The remainder of the male genitalia, including the basal piece, are distinctively shaped, allowing the identification. The male genitalia drawing of Makhan (1992) shows the paramere tips to be present, but the drawing is very generalized, and only one view is given.
