Key to Chinese Colletes clypearis   -group known species

Males: Antennal flagellum 11 segmented. For the identification of males, it is generally recommended and necessary for most species to dissect genitalia and especially S 7. Due to variation in size and outer morphology, the shape and size of S 7 is the easiest and most reliable character for the identification of the majority of species. For all species (except C. hirsutus   sp. n., C. inspersus   sp. n., C. xuezhongi   sp. n., C. yanruae   sp. n. and C. xizangensis   sp. n., for which males are unknown), S 7, genitalia and metasoma has been imaged to facilitate identification.
