The first Geinitziidae (Polyneoptera: Reculida) from the Upper Triassic Amisan Formation of South Korea

Shurabia taewani sp. nov., is the first representative of the reculid family Geinitziidae described from the Upper Triassic of South Korea. The preservation of numerous wing venation characters on this new fossil allows for its placement in the genus Geinitzia and a deep comparison with other genera of Geinitziidae. This discovery suggests that the insect paleofauna of the Amisan Formation is rich and needs to be further investigated. Shurabia taewani sp. nov. differs from the other species currently included in the genus, inter alia, because its vein ScP ends near wing mid-length, its fork of M is at the same level as the fork of R, its RP has five branches, its MA four branches, its MP two branches, and its vein m-cua ‘M5′ originates from the stem of M and ends into CuA.
