2019年7月4日 · A unique feature among bees is the ability of some species of Megachile Latreille s.l. to cut and process fresh leaves for nest construction. The presence of a razor between the female mandibular teeth (interdental laminae) to facilitate leaf-cutting (LC) is a morphological novelty that might have triggered a subsequent diversification in this ...

We favour a classification that recognizes seven morphologically well-delimited genera in Megachilini: Coelioxys, Gronoceras, Heriadopsis, Matangapis, Megachile, Noteriades and Radoszkowskiana.

2016年10月1日 · Our phylogenetic analysis provides the first comprehensive phylogeny of the species-rich bee tribe Megachilini, with a particularly dense taxon sampling that covers most of the diversity observed within the tribe: all genera and 81% of currently recognized subgenera of the genus Megachile, including all three of Michener’s groups. A large ...

Our analysis shows that Fideliinae and the tribes Anthidiini and Osmiini of Megachilinae are paraphyletic; it supports the monophyly of Megachilinae, including the extinct taxa, and the sister group relationship of Lithurgini to the remaining megachilines.

2016年10月14日 · The Megachilini is the most speciose tribe within Megachilidae, comprising four genera: Coelioxys Latreille, 1809, Megachile Latreille, 1802, Noteriades Cockerell, 1931, and Radoszkowskiana Popov, 1955. In spite of its high diversity and ubiquity, the phylogenetic relationships both within and among the genera are still obscure.

Using a cladistic analysis of adult external morphological characters, we explore the relationships of the eight tribes and two subtribes currently recognised in Megachilidae. Our dataset included 80% of the extant generic‐level diversity, representatives of …

2019年7月3日 · Herein, using a cladistic analysis of adult external morphological characters, we explored the relationships of all genera of Megachilini and the more than 50 subgenera of Megachile s.l. We coded...

2016年10月1日 · A new identification key is presented for the western Palearctic subgenera of the bee genus Megachile. In addition, the species composition of each subgenus is discussed, and for large subgenera, … Expand

A new species of leafcutter bee, Megachile (Megachiloides) chomskyi, is described from Texas, United States and probably shows oligolecty with Onagraceae (Evening-Primrose Family). Expand
