Nomenclature and status of the Neurothemis tullia complex of species (Odonata: Libellulidae)

摘要

Continental and Javanese specimens of the Neurothemis tullia-group were studied with an emphasis on wing color pattern and structure of the median process of the vesica spermalis. Continental N. tullia consists of two main variants: one well-known with a variable white wing pruinescence and a dry season variant in which it is lacking. The type of Libellula equestris var. feralis represents a distinct Javanese species, thus N. feralis is raised from being a subspecies of N. tullia to a full species. The variations of the wings as well as the median process of the vesica spermalis of both species are illustrated.
