We used Bayesian inference analyses to estimate the phylogenetic tree topology and divergence times. Biogeographical relationships were investigated using event-based analytical methods: a Bayesian approach to dispersal–vicariance analysis, a likelihood-based dispersal–extinction– cladogenesis model and a Bayesian model. We also used lineage through time analyses to explore the tempo of radiations of Colletidae and their context in the biogeographical history of these bees.

Entre ellos, las abejas constituyen un eslabón esencial en la polinización de angiospermas que durante millones de años desarrollaron estrategias cada vez más específicas para atraerlas. De esta forma se establece una relación muy fuerte entre am- bos, planta-polinizador, y cuanto mayor es la especialización, tal como sucede en un gran número de especies de orquídeas y cactáceas entre otros grupos, ésta se torna más vulnerable ante cambios ambientales naturales o producidos por el hombre. De esta forma, el estudio de este tipo de interacciones resulta cada vez más importante en vista del incremento de áreas perturbadas o modificadas de manera antrópica en las cuales la fauna y flora queda expuesta a adaptarse a las nuevas condiciones o desaparecer.

  • Nesting Biology of the Australian Solitary Bee Paracolletes Crassipes Smith (Hymenoptera: Colletidae) Accords with That of the Diphaglossinae Terry F
    RECORDS OF THE WESTERN AUSTRALIAN MUSEUM 35 053–062 (2020) DOI: 10.18195/issn.0312-3162.35.2020.053-062 Nesting biology of the Australian solitary bee Paracolletes crassipes Smith (Hymenoptera: Colletidae) accords with that of the Diphaglossinae Terry F. Houston Collections and Research, Western Australian Museum, 49 Kew Street, Welshpool, Western Australia 6106, Australia. Email: [email protected] ABSTRACT – Discovery of an extensive nesting aggregation of Paracolletes crassipes in south- western Western Australia enabled the frst study of the nesting biology of this species and its genus. Nest burrows were excavated in deep loam in a clearing in sclerophyll forest. Like New World Diphaglossinae, females of P. crassipes constructed vertically oriented brood cells with strongly curved, polished necks; larval provisions were partly liquid and partly solid; mature larvae spun cocoons with fat tops and produced a clear liquid (evidently from the Malpighian tubules) at the time of defaecation. The cocoons of P. crassipes differed from those of other diphaglossines in having solid tops and no covering of the larval faecal masses. Overall, the nesting biology tends to support the inclusion of Paracolletes in the Diphaglossinae. KEYWORDS: brood cells, cocoons, foral preferences, larval provision, mate-seeking INTRODUCTION New World Diphaglossinae than to other hairy colletids, Paracolletes crassipes Smith is a medium-sized, even including Anthoglossa Smith which Michener black, hairy bee that is recorded from both eastern and (1965, 2007) had treated as a subgenus of Paracolletes. western Australia (Atlas of Living Australia, accessed Accordingly, Almeida et al. (2012) removed Paracolletes March 2020). Western Australian Museum collection from the clade containing the bulk of the bees previously records reveal that, in Western Australia, the species known as Paracolletini and adopted the subfamily occurs south of a line from Jurien to Israelite Bay.
