Confirmation of the synonymy of Rhyzostylops with Blattivorus and the description of the male of Blattivorus inquirendus (Coleoptera: Ripiphoridae: Ripidiinae)
Based on the examination of a winged male collected in central Italy and associated with the holotype (larviform female) of Rhyzostylops inquirendus Silvestri, 1906, the latter species is transferred to the genus Blattivorus Chobaut, 1891 and the synonymy of Rhyzostylops Silvestri, 1906 and Blattivorus is confirmed. The male of Blattivorus inquirendus (Silvestri, 1906), comb. nov. is described. A key to the European genera of Ripidiinae is provided.
