Abstract

Two new species, Pristhesancus nigritus, sp. nov. and P. australis, sp nov., are described from northern Australia. The following synonymies are made: Pristhesancus darwinensis Miller, 1958 with P. grassator Bergroth, 1895; P. fasciatus Reuter, 1881, P. uniformis Distant, 1903, P. luteicollis Walker, 1873, P. melitus Distant, 1903, P. ruralis Miller, 1958 and P. nigridorsum Miller, 1958 with P. plagipennis Walker, 1873. A key to the Australian species is given. A lectotype has been designated for Pristhesancus grassator Bergroth.
