Records of Neurothemis nesaea from Sulawesi, with taxonomic annotations on the N. intermedia-group (Odonata: Libellulidae)

摘要

Several specimens of Neurothemis nesaea from Central and South Sulawesi were examined. This species hitherto was only known from the original description. Figures of both sexes, annotations concerning the habitat and the type specimens are given (two syntypes deposited at SMF and one at ZMH). For comparison, figures of the wings of N. inter media intermedia (holotype is deposited at RBINS), N. intermedia atalanta (two syntypes are deposited at NMS) and N. intermedia excelsa are provided, as well as figures of N. degener (three syntypes are deposited at RBINS). Neurothemis degener is not associated with N. intermedia but considered to represent a full species. Neurothemis septentrionis (holotype is deposited at UMMZ) is synonyrnized with the nominate subspecies of N. intermedia.
