Revisiting the ambush bug genus Neoanthylla Kormilev, 1951 (Reduviidae, Phymatinae)

Neoanthylla (Kormilev, 1951) is a Neotropical genus of Phymatinae with three valid species: Neoanthylla bucki (Kormilev), Neoanthylla horvathi (Handlirsch), and Neoanthylla peruviana Kormilev. Morphologically, it is characterized by the elongated and oval profemur with the cuticular surface smooth and shiny; the procoxa long and subequal to the mesofemur; the prosternal carina long, reaching the anterior margin of the mesosternum; and the abdomen posteriorly entire. Neoanthylla species are scarcely documented in the literature, and the genital structures are unknown. In addition, the Brazilian species (N. bucki and N. horvathi) are known only by female specimens. Here, Neoanthylla is revisited, the diagnoses of the valid species are improved, images of the holotypes of N. horvathi and N. peruviana are provided, and the male of N. horvathi is described for the first time, including genital characters.
