“…The number of species in each clade considered for the analyses (i.e., the 59 genera or groups of species assumed to be monophyletic or least inclusive suprageneric groups about which monophyly could be assumed shown in Supporting information Figure ) was based on the respective number of described species, as indicated in the available catalogues for the neotropical and Australasian bee faunas (Almeida, ; Moure, Graf, & Urban, ) complemented by more recent publications (Batley & Houston, ; Gonzalez & Florez, ; Maynard, ; Almeida & Gibran, ; Packer & Ruz, ). The shape of the LTT plot is affected by the level of taxon sampling in relation to all extant lineages of the investigated clade.…”

The diversification of neopasiphaeine bees during the Cenozoic (Hymenoptera: Colletidae)

et al. 2018

The biogeography of colletid bees as a whole can be explained by several South American-Australian trans-Antarctic interchanges. Within Colletidae, neopasiphaeine bees form a large group that has not been adequately studied, even though they are interesting both from the biogeographical viewpoint for fitting well the austral Gondwanan track and for their associations to host plants. The present paper integrates phylogenetic, biogeographic and paleontological data to reconstruct the evolutionary history of Neopasiphaeinae, with special emphasis on the New World taxa, relating the evolution of these bees to changes, such as the Andes uplift and expansion of open vegetation biomes. First, we propose a phylogenetic hypothesis for the Neopasiphaeinae using one mitochondrial and five nuclear loci. Phylogenetic relationships and divergence time estimation were simultaneously inferred in a Bayesian framework, and the tempo of neopasiphaeine diversification was investigated using lineage-through-time plots. The historical biogeography of neopasiphaeine bees was investigated in a likelihood framework. The clade represented by Neopasiphaeinae is strongly supported within Colletidae, and the bulk of their genera can be divided into two major sister-clades that diverged during the Eocene: one endemic to the Australian region and the other to the Neotropical region. Divergence times among most neotropical genera of Neopasiphaeinae indicate that they differentiated and started their diversification during the Miocene. Our results depict a complex process of geographic evolution in the Neotropical clade, which probably relates to important changes in the neotropical climates and biota beginning at the Oligocene and became more marked in the Miocene. We present a scenario of the neotropical Neopasiphaeinae initially associated with areas of open vegetation in subtropical and temperate portions of South America, followed by multiple separations of lineages east and west of the Andes, and more recent occupations of habitats in tropical portions of the continent.

“…Specimens of Trichocolletes and Goniocolletes were identified using identification keys in recent revisions of these genera by Batley and Houston (2012) and Maynard (2013) respectively. The identified specimens were compared to type specimens and other reliably named material at the Queensland Museum, the Western Australian Museum and the South Australian Museum.…”

“…Previously the male of Trichocolletes luteorufus was unknown (Batley and Houston 2012). The sexes were linked based on the fact that both males and females were collected on the same flowering bush of Senna glutinosa subsp. chatelainiana, where males were chasing females of this species.…”

“…Therefore, species identification and recognition of new species is most straightforward for those genera that have recently been revised and where species identification keys have been included in the revision (Hogendoorn et al 2015). Here, we describe species in two genera of Colletidae that were revised recently ( Trichocolletes : Batley and Houston 2012; Goniocolletes : Maynard 2013). The descriptions cover related genera and involve one new species, one redescription and a description of a male for a species of which hitherto only the female was known.…”

“…Unfortunately, the ethology of relatively few Australian colletid bees has been studied in any detail. This paper will advance knowledge of the nesting biology of one endemic bee genus, Trichocolletes Cockerell, 1912 which is represented in all Australian states and territories by 40 described species (Batley & Houston 2012). The majority of these species forage on pea-flowers (Fabaceae).…”

On the remarkable nesting biology of an Australian bee in the genus Trichocolletes Cockerell (Hymenoptera: Colletidae)

Nests and life‐cycle stages of bees in the endemic Australian bee genus Trichocolletes have been little studied hitherto. Discovery of a nesting aggregation of Trichocolletes orientalis near Perth, Western Australia, provided an excellent opportunity to extend knowledge of the genus, and some surprising facts have emerged from observations made in the field and laboratory. Brood cells were more or less vertically oriented, had cemented earthen walls and were lined internally with thin membranes of cellophane‐like material as is usual for Colletidae. Cell plugs, however, were unusual in that the inner surface of each was thinly coated with white, dry foam and had a central pore. Simple tests indicated that the foam was composed of a wax‐like lipid. Adults were in flight at the nesting site during August and September but absent in November and December when brood cells were excavated. These cells contained mature, pre‐defaecating larvae (not prepupae, as was expected) and no pollen provision or faeces. The larvae and the cell walls around them were heavily coated with oil, evidently pollenkitt derived from pollen in the larval mid‐gut. The possible function and fate of this oil is discussed. Larvae remained dormant through summer, then defaecated, pupated and reached pharate adult stage by late April. Adults eclosed in late May and early June and had very well‐developed fat bodies, so presumably, they overwinter in the nests. Notes on nests of some other Trichocolletes species are included for comparison.
