Excerpt: The Tarsophlebiidae is an extinct family of medium-sized fossil odonates from the Upper Jurassic and Lower Cretaceous period of Eurasia. They are either the most basal member of the damsel-dragonfly grade ("anisozygopteres") within the stem group of Anisoptera, or the sister group of all Recent odonates. They are characterized by the basally open discoidal cell in both pairs of wings, very long legs, paddle-shaped male cerci, and a hypertrophied ovipositor in females. Tarsophlebia eximia, Upper Jurassic, Solnhofen Plattenkalk, head of male specimen MCZ 6129 Tarsophlebia eximia, Upper Jurassic, Solnhofen Plattenkalk, right hind leg of holotypeThe head is similar to that of Recent Gomphidae with two large and globular compound eyes that are distinctly separated, but closer together than in damselflies (Zygoptera). There are also two cephalic sutures.The pterothorax seems to be even more strongly skewed than in damselflies. The legs are extremely long with short and strong spines, and with very elongate tarsi. There are three tarsal segments (tarsomeres), of which the most basal...
