Abstract
The genera Paramacroxiphus C.Willemse 1961 and Pseudomacroxiphus C.Willemse 1961 (Orthoptera: Tettigoniidae: Conocephalinae: Agraeciini) from New Guinea, previously regarded to be monotypic, are revised. Nine Paramacroxiphus species are described as new: P. armatus sp. n., P. bifasciatus sp. n., P. brunneus sp. n., P. elongatus sp. n., P. irregularius sp. n., P. maculatus sp. n., P. rufus sp. n., P. securiformis sp. n., P. uniformis sp. n.; P. tessellatus (Karny, 1912) becomes a new combination from Nicsara Walker, 1869. A key to the nine species of Paramacroxiphus is given. Pseudonicsara szentia C.Willemse, 1958 is newly combined with Pseudomacroxiphus. Pseudomacroxiphus atrifrons C.Willemse, 1961 becomes a new synonym of P. szentia. Pseudomacroxiphus thus remains monotypic. P. szentia is distributed throughout New Guinea, while Paramacroxiphus species colonise restricted areas, replacing each other geographically, although two localities are known that host more than one species.
