Agyrtacantha picta sp. nov., a new dragonfly from southern Papua New Guinea (Odonata: Aeshnidae)

摘要

A new species of Agyrtacantha is described from the Purari River basin in Gulf Province, Papua New Guinea. The new species is most similar to A. dirupta, a species widespread in the Papuan region, but differs from that species and other known congeners by the unique colour pattern on the front and sides of the synthorax and the particularly long and slender anal appendages. Both sexes are described and illustrated, and the species is compared with its most similar congeners.
