Abstract

A brief taxonomic and nomenclatural history of Zoraena Kirby and its species is presented. The adults of Z. bilineata n. sp. are described, and Z. bilineata n. sp., Z. diastatops (Selys), and Z. sayi (Selys) are figured. The new species may be readily distinguished from other species of Zoraena by the brown base color and less extensive yellow markings of the body, and by the shape of the male terminalia. The type locality is in western Virginia, and the type series includes specimens collected in an area extending from Delaware and Michigan to Mississippi and Georgia. The new species inhabits spring runs where the males characteristically perch on sunlit plant stems. A key to adult American Cordulegastridae is provided, and the taxonomic position of Zoraena and related genera is discussed.
