Systematic Entomology, Volume 50, Issue 2, Page 325-348, April 2025.A newly expanded UCE phylogeny of Dorymyrmex robustly confirms the major lineages and recommends a new scheme of four major species groups. The asymmetrical, amphitropical distribution of Dorymyrmex was likely created by a single dispersal event across the Isthmus of Panama before the traditional closure date of 3 Mya.

Floral Resources Partitioning by Two Co-occurring Eusocial Bees in an Afromontane Landscape
Sociobiology, 2018 Floral preferences of generalist foragers such as eusocial bees influence the success of pollination of many flowering plants, as well as competition with many other bee species in tropical communities.

International Scholarly Research Notices, Volume 2013, Issue 1, 2013., 2013 We describe two new species of bees from Colombia; one is a species of Exomalopsis found nesting in the city of Medellin, Colombia, (the host) and its cleptoparasitic bee, a species of the genus Nomada. In addition, we provide information on the nest architecture of the new species and provide data on occupancy by both the host bee and its ...

Description of an ancient social bee trapped in amber using diagnostic radioentomology [PDF]
, 2018 The application of non-invasive imaging technologies using X-radiation (diagnostic radioentomology, ‘DR') is demonstrated for the study of amber-entombed social bees. Here, we examine the external and internal morphology of an Early Miocene (Burdigalian)

First records of four orchid bee species (Hymenoptera, Apidae: Euglossini) in Ecuador [PDF]
Journal of Insect Biodiversity and SystematicsOrchid bees (Hymenoptera, Apidae, Euglossini) play a vital role as key pollinators in the Neotropical forests. Their preference for forested areas makes these bees more susceptible to environmental changes, particularly in areas under severe human impact,

Miocene honey bees from the Randeck Maar of southwestern Germany (Hymenoptera, Apidae)
ZooKeys, 2011 The Miocene Randeck Maar (southwestern Germany) is one of the only sites with abundant material of fossil honey bees. The fauna has been the focus of much scrutiny by early authors who recognized multiple species or subspecies within the fauna.

Phylogenetic relationships within the corbiculate Apinae (Hymenoptera) and the evolution of eusociality [PDF]
Journal of Evolutionary Biology, 1999 Abstract We provide a comparison of 520 base pairs of the mitochondrial cytochrome b gene from exemplars of the Meliponini, the Apini, the Bombini and the Euglossini to determine the phylogenetic relationships within the corbiculate Apinae.
