Taxonomic Study of the Japanese Species of the Nomada ruficornis Species Group (Hymenoptera, Apidae) with Remarks on Japanese Fauna of the Genus Nomada

Abstract

The ruficornis species group of genus Nomada in Japan is taxonomically revised. Thirty species are recognized, including two new species and one species newly recorded from Japan. Thirty-two species and two subspecies are synonymized. In comparison with the faunas of European countries, the fauna of the Japanese Nomada is moderate in terms of the number of species, and is characterized by (1) a rich roberjeotiana species group, and (2) the absence of the integra and superba species groups, which are distributed widely in the Palearctic region.

Harrison’s Rule Corroborated Among Nomadine Cuckoo Bees (Hymenoptera: Apidae: Nomadinae) : The Role of Body Size in Host-Switching Dynamics

“…Following prior works on the group, Alexander conducted species-group classi cation in the genus Nomada based on cladistic analyses [42]. There, he de ned 16 species-groups, and this classi cation has been commonly used since [34,41,43,44]. However, he mentioned that one of the species-groups, the ru cornis species-group, may actually belong to a larger group without relatively distinct apomorphic subunits, such as the armata or basalis group [41,43].…”

Records of Cleptoparasitic Bees from North Korea, with a Redescription of Nomada shoyozana Tsuneki, 1983

“…This species is widespread and common in Japan. Tsuneki (1986) and Mitai & Tadauchi (2007) already reported the occurrence of it in South Korea, and…”

“…This species is originally described based on two females collected from Mt. Esan, Hokkaido, Japan, and later has been obtained in central Honshu, Japan (Mitai and Tadauchi, 2007). This is the first record from the Eurasian continent.…”
