Febraina: a new subtribe of Alticini with cladistic analysis based on morphology (Coleoptera: Chrysomelidae: Galerucinae)

A new subtribe Febraina subtr.n. is established with Febra Clark designated as the type genus. Cladistic analysis based on morphological characters is carried out to reveal the composition of a new subtribe and to test its monophyly. Subtribe includes the following genera: Chilocoristes Weise; Halticorcus Lea; Setsaltica Samuelson; Maaltica Samuelson; Axillofebra Samuelson; Profebra Samuelson. Bionomical features of the genera of the subtribe are summarised. The syndrome of hemisphery is recorded for the genera of the subtribe, and morphological transformation resulting in hemisphery is described and discussed. Correspondence between direction of morphological transformation, phylogenetic arrangement of genera, and distributional pattern is recorded and discussed.
