Neoconocephalus Karny, 1907

Homorocoryphus Karny, 1907

The species described as Homorocoryphus passed to Ruspolia according to Bailey’s (1975) synonymy. However, Ruspolia is a genus originally only known from the Old World, and Piza’s species would be the only ones for the Americas. But Piza (1958, 1971, 1973, 1983) referred to H. ensifer , H. finitimus , and H. occidentalis to compare and describe his species, and those three species have been moved to Neoconocephalus : N. ensifer , N. finitimus , and N. occidentalis . Although Piza described species in Neoconocephalus as well as Homorocoryphus , he never clarified which characters he used to separate these two genera. We include all species in Neoconocephalus . Unfortunately this increases the taxonomic confusion of this large genus even more, with more than 100 species from South America currently considered valid.
