Genus Brachyxystus Faust, 1897 View in CoL , reestablished tribal placement

Brachyxystus Faust, 1897: 355 View in CoL , type species by original monotypy Brachyxystus subsignatus Faust, 1897 View in CoL (classified as Phyllobiini View in CoL ); Marshall 1916: 279 (classified as Ectemnorhinini Lacordaire, 1863 View in CoL ); Thompson 1977: 460 (classified as Polydrusini View in CoL ); Alonso-Zarazaga and Lyal 1999: 173 (classified as Phyllobiini View in CoL ).

Notes.

The major characteristic of Polydrusini that differentiates it from Phyllobiini is the lateral position of the antennal scrobes. We agree with the conclusion of Thompson (1977), who conducted a comparative morphological analysis and proved affinity of Brachyxystus with Pachyrhinus Schoenherr, 1823 and its placement in Polydrusini . We disagree with Alonso-Zarazaga and Lyal (1999) who transferred the genus to Phyllobiini without explicit justification. In addition to the morphology of the head, the structure of the aedeagus also supports the affinity of Brachyxystus with Pachyrhinus within Polydrusini .
