Review of the Philippine taxa formerly assigned to the Genus Amphicnemis Selys. Part III. Genus Pericnemis: Bonita- and Incallida- groups with descriptions of four new species (Odonata: Coenagrionidae)

The species formerly assigned to the genus Amphicnemis Selys, 1863 in the Philippines are reviewed. The present paper is the third of a series and deals with the species transferred to the genus Pericnemis Hagen in Selys, 1863. Specimens used in the study are all deposited in museums collections. The bonita- and incallida-groups of Pericnemis from the Philippines are characterized. A key to species groups within Pericnemis is given, and also a key to the males of the bonita- and incallida-groups. The bonita-group includes five species: P. bonita Needham & Gyger, 1939, P. flavicornis Needham & Gyger, 1939, P. bisaya sp. nov., P. gili sp. nov. and P. muragbonita sp. nov. The incallida-group includes two species: P. incallida Needham & Gyger, 1939 and P. yakal sp. nov. Descriptions and illustrations are provided of both sexes of all species.
