A new genus of Strepsiptera, Rozenia gen. n. (Stylopidae), a parasite of bee genera Acamptopoeum and Calliopsis (Andrenidae, Panurginae, Calliopsini)

摘要

A new Strepsiptera genus from South America is described, Rozenia gen. n., with three new species: Rozenia calliopsidis sp. n. (type species), Rozenia peruana sp. n. and Rozenia platicephala sp. n. These three new species are parasites of bees belonging to the tribe Calliopsini (Andrenidae, Panurginae). Rozenia calliopsidis sp. n. is a parasite of the bee genus Calliopsis Smith, 1853 and Rozenia peruana sp. n. and Rozenia platicephala sp. n. are parasites of the bee genus Acamptopoeum Cockerell, 1905. Diagnoses and descriptions of female puparia are presented for all three species. Diagnoses and descriptions of first instars (triungulinids) are presented for Rozenia calliopsidis sp. n. and Rozenia platicephala sp. n. The first case of increased number of setae on the body of the first instars and augmentation of chaetotaxy of Strepsiptera are discussed.
