Taxonomy, phylogeny and distribution of the longicorn beetle genus Allotisis Pascoe (Coleoptera: Cerambycidae: Phoracanthini)

Abstract

The genus Allotisis Pascoe is revised. Diagnosis of Allotisis is given, three known species are redescribed and six species are described as new : A. repleta, A. notabilis, A. rara, A. labyrinthina, A. monteithi and A. furva. All species are from Australia. Thoris moerens Blackburn is synonymous with A. unifasciata. A key to the nine species is provided. Phylogenetic analysis suggests that this genus be divided into two species groups, monteithi-group and unifasciata-group. Several subgroups are also identified. Biogeographic distribution of these species groups and subgroups is discussed.
