A review of <i>Paratranes</i> Zimmerman, 1994, <i>Xanthorrhoea</i>-associated weevils of the Tranes group (Coleoptera, Curculionidae, Molytinae), with description of a new species

Grasstrees (Xanthorrhoea) are a group of monocotyledonous plants endemic to Australia, with a characteristic crown of long and narrow leaves. In the present study, the grasstree-associated weevils of the genus Paratranes Zimmerman, 1994 are reviewed and two species are recognised: P. monopticus (Pascoe, 1870) and P. zimmermani sp. nov. A lectotype for Tranes xanthorrhoeae Lea, 1898, which was recently synonymised with P. monopticus, is herein designated, and the validity of this synonymy is confirmed. Descriptions and diagnoses of the species are supplemented with photographs of their habitus and salient structures as well as a map of their distributions.</p

A review of the trunk‐boring cycad weevils in Australia, with description of a second species of Demyrsus Pascoe, 1872 (Coleoptera: Curculionidae)

The Australian trunk‐boring cycad weevils of the genera Demyrsus Pascoe, 1872 and Siraton Hustache, 1934 (Molytinae) are sometimes considered as cycad pests when they infest planted cycads and can be transported to other countries. In the present study, the taxonomy of Demyrsus and Siraton is reviewed, and four species are recognised: D. meleoides Pascoe, 1872, D. digmon sp. nov., S. internatus (Pascoe, 1870) and S. roei (Boheman, 1843). The discovery of a second species of Demyrsus illustrates a larger diversity of cycad‐associated weevils in Australia than currently known and identifies a further species with the potential to damage and kill cultivated cycads. The species descriptions and diagnoses are supplemented with illustrations of the habitus and salient structures, a distribution map and an identification key to all species of trunk‐boring cycad weevils in Australia. Their potential hosts are identified from a spatial analysis of their distributions and the distributions of the cycad taxa occurring in this range

Taxonomic Revision of the Genus <i>Miltotranes</i> Zimmerman, 1994 (Coleoptera: Curculionidae: Molytinae), the <i>Bowenia</i>-Pollinating Cycad Weevils in Australia, with Description of a New Species and Implications for the Systematics of <i>Bowenia</i>

The Australian endemic weevils of the genus Miltotranes Zimmerman, 1994 (Curculionidae: Molytinae: Tranes group), comprising two species, M. prosternalis (Lea, 1929) and M. subopacus (Lea, 1929), are highly host-specific and the only known pollinators of Bowenia cycads, which comprise two CITES-protected species restricted to Tropical Queensland in Australia. In the present study, the taxonomy of Miltotranes is reviewed, a lectotype for the name Tranes prosternalis Lea, 1929 is designated and a new species associated with the Bowenia population in the McIlwraith Range is described as M. wilsoni sp. n. The descriptions and diagnoses of all species are supplemented with illustrations of their habitus and salient structures, and an identification key to all species and a distribution map are provided. Potential implications of the new species and of the taxonomy and biogeography of Miltotranes overall on the systematics and conservation of Bowenia are discussed

A review of Paratranes Zimmerman, 1994, Xanthorrhoea-associated weevils of the Tranes group (Coleoptera, Curculionidae, Molytinae), with description of a new species

Grasstrees (Xanthorrhoea) are a group of monocotyledonous plants endemic to Australia, with a characteristic crown of long and narrow leaves. In the present study, the grasstree-associated weevils of the genus Paratranes Zimmerman, 1994 are reviewed and two species are recognised: P. monopticus (Pascoe, 1870) and P. zimmermani sp. nov. A lectotype for Tranes xanthorrhoeae Lea, 1898, which was recently synonymised with P. monopticus, is herein designated, and the validity of this synonymy is confirmed. Descriptions and diagnoses of the species are supplemented with photographs of their habitus and salient structures as well as a map of their distributions

Bionomics and rearing of Miltotranes prosternalis (Lea, 1929) (Coleoptera: Curculionidae), a mutualistic cycad pollinator in Australia

Pollination is the crucial stage for reproduction and survival of plants, therefore knowledge about the bionomics of pollinators is often critical for plant conservation. Bowenia spectabilis (Cycadales: Stangeriaceae) is a CITES-protected cycad species endemic to the Wet Tropics Bioregion of Queensland, Australia. It is pollinated by a host-specific weevil species, Miltotranes prosternalis (Lea, 1929) (Curculionidae: Molytinae), which breeds in its male cones but also visits its female cones and pollinates them. The association between the cycad and the weevil is an obligate brood-site reward pollination system, in which the weevil is provided with food and a brood site by the plant in “return” for the service of pollinating it. To facilitate the knowledge of the natural history of this unique Bowenia pollinator, we developed a method for rearing mature larvae of M. prosternalis collected from the field in the laboratory. Furthermore, we summarize biological information of M. prosternalis gathered from previous studies and by firsthand observations in the wild and during rearing in captivity
