Abstract

The genus Calcyopa Stüning, 2000, is briefly reviewed. A new species, Calcyopa hainana Liu, sp. nov., is described from Hainan Province, China. Within the genus Calcyopa, two species groups are identified, characterized by shared traits yet distinguished by a set of consistent features. The difoveata-group, comprises C. difoveata, C. fansipana and C. hainanasp. nov., and the rosearia-group, includes C. rosearia, C. prasina and C. subprasina. The relationship of both species groups is discussed, and an identification key of all known Calcyopa species is presented. Illustrations are provided for adult males and females of the difoveata-group, along with their genitalia, except for C. fansipana, which is known only from males. DNA barcodes are provided for the type species and the newly described species.
