Abstract
A new species, Eogyropsylla sedzimiri sp. nov. from Eocene Baltic amber is described. Illustrations of head, thorax, fore-wing, hind wing, antennae, legs and female terminalia are given. A key to the species of the fossil genus Eogyropsylla Klimaszewski, 1993 is also provided. The psyllids, or jumping plant-lice, are a group of small sap-sucking sternorrhynchous Hemiptera. The extant representatives of Psylloidea comprise 3000-3500 described species (Burckhardt et al. 2005; Ouvrard et al. 2008). Psyllids have a worldwide distribution—from arctic and subarctic parts of Alaska (Hodkinson 1978; Hodkinson & MacLean 1980a), Chukotka and Northeast Russia (Hodkinson MacLean 1980b), to the hot zones of South America (Burckhardt 1987 a, b, 1988), Africa (Hollis 1984) and Australia (Hollis 2004), but they exhibit greatest diversity in tropical regions. Most psyllids are monophagous, having only one host plant, or oligophagous, with a few, closely-related host-plants, and only a few are polyphagous (Ossiannilsson 1992).
