Genus Hexocera Hancock, 1915

syn. nov. of Scelimena

Hexocera: Hancock 1915, Günther 1938a, Blackith 1992, Yin et al. 1996, Otte 1997.

Type species: Acridium hexodon Haan, 1843 .

Composition and distribution. Monotypic genus with its only species ( H. hexodon) inhabiting Borneo.

Notes. The genus is synonymous with Scelimena . This monotypic genus included only H. hexodon (de Haan, 1843), characteristic in extremely high pronotal projection, forming strong and sharp spines. The genus shares all the morphological characters with Scelimena . S. hexodon comb. resurr. (Fig. 11) is restricted to Borneo, and Blackith's (1992) record of the species for Sumatra was not confirmed. However, in Sumatra, a new species is found ( Scelimena marta sp. nov.) closely related to S. hexodon . Since the presence of the large spines is the only character separating Hexocera from Scelimena (and it is not really separating character), we synonymize Hexocera syn. nov. with Scelimena . Borneo is inhabited by a few species with pronotal projection much larger than in their congers (e.g., Discotettix belzebuth, Tegotettix armatus), and so S. hexodon also have the largest spines within the genus.
