Two Armigeres species of Manipur, the easternmost Northeast India

摘要

In the endeavour for diversity assessment of mosquitoes of Manipur, an attempt has been made to identify vector mosquitoes. In quest for proper investigation of the vector mosquitoes two Armigeres spp are reported. They are Armigeres (Armigeres) obturbans (Walk.), 1860 and Armigeres (Armigeres) aureolineatus (Leicesyer), 1908. They are systematically analysed in the present study. The two species are all identical externally from larvae to adult individual through pupal stages. But microscopic features are quite different in these species. Main differences could be found in the male hypopygium particularly the number of teeth along stylar. In Armigeres obturbans the number of teeth is 17 to 19 while in Armigeres aureolineatus it is only 15 to 16. The two species are from Jiribam and Moreh where the annual temperature is much higher than other parts of Manipur. It will be quite safe to argue that the species might inhabit the area with higher temperature. Armigeres aureolineatus is a new report from the state of Manipur as the available literatures. The species Armigeres obturbans could not be synonymized with Armigeres subalbatus as reported from Manipur . The ascertaining of the two species with the molecular work will the future perspective and exploration more species of the genus will have enriched the diversity of the state and India as whole.
