title: A new genus of Strepsiptera, Rozenia gen. n. (Stylopidae), a parasite of bee genera Acamptopoeum and Calliopsis (Andrenidae, Panurginae, Calliopsini).
abstract: A new Strepsiptera genus from South America is described, Rozenia gen. n., with three new species: Rozeniacalliopsidis sp. n. (type species), Rozeniaperuana sp. n. and Rozeniaplaticephala sp. n. These three new species are parasites of bees belonging to the tribe Calliopsini (Andrenidae, Panurginae). Rozeniacalliopsidis sp. n. is a parasite of the bee genus Calliopsis Smith, 1853 and Rozeniaperuana sp. n. and Rozeniaplaticephala 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 Rozeniacalliopsidis sp. n. and Rozeniaplaticephala 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.
