Coeliccia southwelli sp. nov. (Odonata: Zygoptera: Platycnemididae) from Mount Dulit, Sarawak

摘要

Coeliccia southwelli sp. nov. is described from Mount Dulit, Miri and Kapit Divisions, Sarawak, Malaysian Borneo. It belongs to the borneensis'-group of species, and is the sixth species from this group to be described from Borneo. New material of other borneensis-group species is put on record. The borneensis-growp of species from the platycnemidid calicnemiine genus Coeliccia Kirby, 1890 was recently treated in detail (Dow 2010); the reader is referred to this publication for a characterisation ofthe group. However some issues remained unresolved because of insufficient material. In particular a female specimen from the Natural History Museum, London (BMNH) could not be assigned to any named species.
