Abstract
The new genus Lobofemora gen. nov. is described from Vietnam to accommodate three new species: L. bachmaensis sp. nov. (Bach Ma National Park, central Vietnam), L. bidoupensis sp. nov. (Bidoup-Nui Ba National Park, central Vietnam) and L. scheirei sp. nov., the type species (Cat Tien National Park and Dong Nai Biosphere Reserve, south Vietnam). It is provisionally placed in the tribe Clitumnini Brunner von Wattenwyl, 1893. The genus is the only known Clitumnini which shows tegmina and sometimes alae in the males. Females show conspicuous foliaceous lobes on the median femora. Males and females of all species and the eggs of L. scheirei sp. nov. and L. bidoupensis sp. nov. are described and illustrated. An identification key to the species and a distribution map are provided. The definition of the tribe Clitumnini sensu Hennemann & Conle (2008) is slightly adapted to include the new genus and the tribal placement is discussed. The male of L. scheirei sp. nov. is able to stridulate by rubbing the outer margins of the tegmina against the subcostal and radial veins of the alae.

The tribe Clitumnini Brunner von Wattenwyl, 1893 was recently re-diagnosed and revised on the generic level by Hennemann & Conle (2008)

Summary
The tribe Clitumnini Brunner von Wattenwyl, 1893 was recently re-diagnosed and revised on the generic level by Hennemann & Conle (2008). Recent expeditions to Vietnam in the frame of a Global Taxonomic Initiative project by the authors and Vietnamese colleagues have revealed three congeneric new species that could not be attributed to any known genus. Following the key of Hennemann & Conle (2008), the new genus belongs in the tribe Clitumnini showing the following typical features: small to medium sized species with body lengths ranging from 71.2 to 95.5 mm in females and 52.5 to 74.0 mm in males; elongate legs; sexual dimorphism distinct; antennae shortened with the scapus enlarged, laterally dilated. The new genus, violates several characters of Clitumnini; it is remarkable and interesting in several aspects. Females with back of the head raised and/or conical
