The first molecular phylogeny of the weevil subfamily Lixinae (Coleoptera: Curculionidae) casts doubts on the monophyly of its tribes.

This paper targets the nearly cosmopolitan weevil subfamily Lixinae. A phylogenetic analysis of one mitochondrial and two nuclear DNA fragments obtained from 87 Lixinae and 49 outgroup terminals strongly supports the monophyly of the subfamily. The molytine tribe Mecysolobini is the likeliest sister group of Lixinae; adults of both taxa share the likely synapomorphic condition of the greatly shortened labial palpi.

Flightless Notaris (Coleoptera: Curculionidae: Brachycerinae: Erirhinini) in Southwest China: monophyly, mtDNA phylogeography and evolution of habitat associations.

This paper reports the recent discovery of flightless populations of weevils of the genus Notaris in Yunnan and Sichuan provinces of China. Specimens were found in the middle or high altitude mountains (2440-4195 m), by either sifting leaf litter in the deciduous forest and among alpine Rhododendron shrubs, or by turning rocks in the alpine zone. These finds extend southwards the Asian range of this Holarctic genus and report its highest altitudinal records.
