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...
متن کاملPhylogenetic relationships and host-plant evolution within the basal clade of Halictidae (Hymenoptera, Apoidea)
Bees are among the most important pollinators of angiosperm plants. Many bee species show narrow host-plant preferences, reflected both in behavioral and morphological adaptations to particular attributes of host-plant pollen or floral morphology. Whether bee host-plant associations reflect co-cladogenesis of bees and their host plants or host-switches to unrelated host plants is not clear. Rop...
متن کاملComparative morphology of spermathecae in solitary and primitively eusocial bees (Hymenoptera; Apoidea)
Spermathecae of solitary and primitively eusocial bees from five major families were compared according to their chamber size, epithelial cell height (wall thickness), number and shape of glands, number of sperm pumps, and diameter of the duct, using whole mounts and serial sections. A thick spermathecal wall with a small chamber in our exemplar colletid, megachilid, and andrenid bees, a large ...
متن کاملEvolution of gall morphology and host-plant relationships in willow-feeding sawflies (Hymenoptera: Tenthredinidae).
There are over 200 species of nematine sawflies that induce galls on willows (Salix spp.). Most of the species are mono- or oligophagous, and they can be separated into seven or eight different groups based on the type of gall that they induce. We studied the evolution of different gall types and host plant associations by reconstructing the phylogeny of five outgroup and 31 ingroup species usi...
متن کاملPhylogeny of the bee family Megachilidae (Hymenoptera: Apoidea) based on adult morphology
Phylogenetic relationships within the bee family Megachilidae are poorly understood. The monophyly of the subfamily Fideliinae is questionable, the relationships among the tribes and subtribes in the subfamily Megachilinae are unknown, and some extant genera cannot be placed with certainty at the tribal level. Using a cladistic analysis of adult external morphological characters, we explore the...
