Reconstruction of Pasternakevia podolica

The prosoma of Pasternakevia covered by a smooth, semicircular carapace with rounded genal cornua (posterolateral corner of carapace).^[1] Within the 10-segmented opisthosoma, tergite of the first segment is reduced and usually hidden under the preceding carapace, while the second one is significantly arched and well-developed.^[1] All but the first tergite possess well-developed pleurae (lateral extension). A complete telson is yet to be discovered.^[1]
