THE BEE-GENUS APISTA, ETC

Unexpected Polylecty in the Bee Genus Meganomia (Hymenoptera: Apoidea: Melittidae)

The melittid bees represent an early branch of bee phylogeny. They are therefore of special interest in understanding the early evolution and diversification of bees. Most species have been observed to be oligolectic (i.e., highly specialized in their choice of host-plant species). However, knowledge of host-plant associations is not equivalent across all melittid groups. Dasypodainae and the M...

Introduction etc

Bilateral and multilateral development cooperation agencies are to an increasing extent promoting and adopting a sector-wide approach (SWAp) in their development cooperation. The Swedish International Development Cooperation Agency (Sida), for example, joined their first sector-wide approach cooperation in the late 90s, and today they are involved in SWAps in countries in Africa, Asia and Latin...

Reports etc

New species of the cleptoparasitic bee genus Stelis (Hymenoptera: Megachilidae, Anthidiini) from the Nearctic Region.

Descriptions and diagnoses of ten new Nearctic species of Stelis subgenus Stelis are presented: S. alta, S. anasazi, S. anthocopae, S. broemelingi, S. imperialis, S. joanae, S. lamelliterga, S. occidentalis, S. paiute, and S. shoshone. Six of these species have been reared from trapnests. Host associations, all within the tribe Osmiini (Megachilidae), are provided.

Revision of the species of the bee genus Caenohalictus (Hymenoptera: Halictidae) occurring in Argentinean Patagonia.

The species of the halictid bee genus Caenohalictus Cameron occurring in Argentinean Patagonia are revised. Eight species are recognized, one of them here described as new: Caenohalictus flammeus n. sp. The female of C. turquesa Rojas & Toro 2000 is described for the first time. Pseudagapostemon babuarus Jörgensen 1912, based on the male holotype, is synonymized under Augochlora (Pseudaugochlor...
