The Hybotidae of the Our Planet Reviewed in Corsica 2019-2021 survey, with the description of three new species of Platypalpus and Tachydromia (Diptera, Empidoidea)

Abstract

In the framework of the Our Planet Reviewed program, a 3-years survey of Corsica was conducted between 2019 and 2021. A total of 3,287 Empidoidea (Diptera) were retrieved from about 17% or 152 out of 876 Diptera samples and examined. They contained 31 representatives of the family Atelestidae, 649 Brachystomatidae, 778 Empididae and 1,829 Hybotidae. The hybotid genera Drapetis Meigen, 1822, Platypalpus Macquart, 1827, and Tachydromia Meigen, 1803, were studied in more detail. Three species are described here as new to science: Platypalpus pseudoarticulatoides Grootaert, n. sp., P. pseudoniveisetoides Grootaert, n. sp. and Tachydromia corsicana Grootaert, n. sp. In addition, some rare species with a limited distribution in Europe such as Drapetis hirsuticercis Stark, 2003, Platypalpus longimanus (Corti, 1907), Platypalpus parvicauda (Collin, 1926), and Platypalpus stigma (Collin, 1926) are discussed here. Platypalpus excavatus Yang & Yao in Yang et al., 2007, is considered as a new objective synonym of Tachydromia excisa Becker, 1907.
