Gregarina tropica n. sp. (Apicomplexa: Eugregarinorida: Gregarinicae: Gregarinidae) Parasitizing the Brown-Winged Earwig, Vostox brunneipennis (Dermaptera: Labiidae), in the Texas Big Thicket

摘要

Gregarina tropica n. sp. (Apicomplexa: Eugregarinorida) is described from the brown-winged earwig, Vostox brunneipennis (Dermaptera: Labiidae) collected from the Turkey Creek Unit, Big Thicket National Preserve, Tyler County, Texas, U.S.A. We review the morphometric data and nomenclatural status of the 8 previously described species of Gregarina infecting earwigs and recognize 7 valid species: Gregarina ovata, Gregarina nalae, Gregarina megaspora, Gregarina ambigua, Gregarina fallax, Gregarina chelidurellae, and Gregarina labidurae. Although apparently valid taxa, the latter3 species are very poorly described and thus considered species inquirendae pending new collections and redescription. Gregarina forficulae is recognized as a junior synonymy of G. ovata.
