New and little known Corduliidae (Odonata : Anisoptera) from the Indo-Pacific region

Abstract

Abstract The article deals with six species of Corduliidae from various localities in the Indo-Pacificregion, of which the following four are new to science : Somatochlora daviesi, sp. nov. (Khasi Hills, Meghalaya), Procordulia fusiformis, sp. nov. (Borneo), P. Morocnsis, sp. nov. (Philippines), and Macromia flinti, sp. nov. (Sri Lanka). Two imperfectly known species, Procordulia irregularis (Fiji Is.) and Macromia zeylanica Fraser (Sri Lanka), are redefined, based on the examination of type specimens and a study of fresh material. A description of the hitherto unknown female of P. Irregularis is also given. Drawings are supplied of the salient structural characters of all species discussed. Referring to earlier publications on the subject, it is considered irrational to detach the Macromia group from the Corduliidae and accept the proposed family-group name Macromii- dae to embrace them : this is rejected in favour of the more judicious solution to leave the group in the subfamily Macromiinae, as it stood before.
