Hydrochus obscurus Sharp, 1882: 90

Originally described from Guatemala. Records from several South American countries are in the literature; however, some of these records are invalid synonymies proposed by Oliva (1992), for H. corruscans Bruch ( Argentina) (see Perkins 2019a), and H. elsjeae Makhan ( Bolivia) (Perkins, in prep.). Locality data and deposition records have been published for Venezuela ( Perkins 2019c). The one locality data record from Peru is given below. Habitus and male genitalia illustrations are given in Perkins (2019c, 2020a).

Material examined (3): PERU: Madre de Dios, Rio Tambopata Res ; 30 air km SW Pto. Maldonado, elev. 290 m (13°0’S, 69°33’W), 16–20.xi.1979, leg. J. B. Heppner (3 NMNH) .
