Abstract
Pristapenesia asiatica sp. nov, is described and illustrated from two female specimens collected in China and Thailand. This species is readily recognized by the absence of a tubular radial vein in the fore wings. A key to world fossil and living species of Pristapenesia is provided. Pristapenesia was originally described .by Brues (1933) to accommodate P. primaeva, an Eocene fossil species from the Baltic region and based on a series of males and a single female "with extremely long, slender abdomenand prothorax much produced anteriorly". At that time he classified the genus in the Bethylidae. Subsequently, Prentice et al. (1996) described Dominibythus, which was later synonymized with Pristapenesia by Brothers and Janzen (1999), and properly assigned the latter to Scolebythidae. Two species were described m Dominibythus and later transferred to Pristapenesia, the Miocene fossil P. inopinata (Prentice & Poinar 1996) in Early Miocene amber from the Dominican Republic, and the extant P. striata (Azevedo 1999) from Brazil.
