A NEW SPECIES AND NOMENCLATURAL CHANCES IN THE SUBGENUS POLYRHACHIS (CYRTOMYRMA) FOREL (HYMENOPTERA: FORMICIDAE: FORMICINAE)

摘要

Polyrhachis dorowi sp. n., a new species of the subgenus Cyrtomyrma Forel from Cape York Peninsula, Queensland, is described and illustrated. Polyrhachis busiris Fr. Smith, 1860, from New Guinea, is removed from synonymy with P. rastellata (Latreille, 1802), redescribed and reinstated as a valid species; a lectotype is also designated. Polyrhachis rastellata baduri Donisthorpe, 1941, from Japen Island off the northwestern coast of Irian Jaya [= West Papua], Indonesia, is considered a new synonym of P. euryala Fr. Smith, 1863. The occurrence of P. debilis Emery in Australia, earlier considered doubtful, is now confirmed by specimens from Melville Island, off the coast of the Northern Territory.
