Australian and New Guinean Stingless Bees of the Genus Austroplebeia Moure (Hymenoptera: Apidae)--a revision.
The stingless bee genus Austroplebeia Moure occurring in Australia and New Guinea is revised, based on a morphological analysis of samples from 177 colonies. Five species are recognised: A. cincta (Mocsáry), A. essingtoni (Cockerell), A. australis (Friese), A. cassiae (Cockerell) and A. magna, sp. nov. Three different colour morphs of A. australis are described. Five new synonymies are proposed...
متن کاملPatterns of host-plant choice in bees of the genus Chelostoma: the constraint hypothesis of host-range evolution in bees.
To trace the evolution of host-plant choice in bees of the genus Chelostoma (Megachilidae), we assessed the host plants of 35 Palearctic, North American and Indomalayan species by microscopically analyzing the pollen loads of 634 females and reconstructed their phylogenetic history based on four genes and a morphological dataset, applying both parsimony and Bayesian methods. All species except ...
متن کاملEcology of Eastern Australian Whipsnakes of the Genus Demansia
Body sizes, food habits and reproduction in eastern Australian elapid whipsnakes are described, based on dissection of 537 specimens. The four species studied are Demansia atra, D. olivacea, D. psammophis and D. torquata. Males attain larger body sizes than females in all species, and male-male combat is recorded in D. atra. The diet consists mainly of lizards, especially skinks. Female reprodu...
متن کاملReview of the Australian wolf spider genus Venator (Araneae, Lycosidae).
Species of the Australian wolf spider genus Venator are reviewed including the type species, V. spenceri Hogg, 1900, from south-eastern Australia and V. immansuetus (Simon, 1909) comb. nov., a common species in south-west Western Australia. Venator marginatus Hogg, 1900 is only known from two female specimens and the genital morphology of this species does not conform to the diagnosis of genus ...
متن کاملPredator-prey coevolution: Australian native bees avoid their spider predators.
Australian crab spiders Thomisus spectabilis manipulate visual flower signals to lure introduced Apis mellifera. We gave Australian native bees, Austroplebia australis, the choice between two white daisies, Chrysanthemum frutescens, one of them occupied by a crab spider. The colour contrast between flowers and spiders affected the behaviour of native bees. Native bees approached spider-occupied...
