Taxonomic and biogeographic revision of the genus Lamellitettigodes (Orthoptera: Tetrigidae) with description of two new species and additional notes on Lamellitettix, Probolotettix, and Scelimena

The genus Lamellitettigodes Günther, 1939 from Southeast Asia is reviewed. The genus currently includes seven species and is transferred to Tetriginae Rambur, 1838. Two new species are described: Lamellitettigodes novaeguineae sp. nov. from New Guinea and Lamellitettigodes karwinkeli sp. nov. from Yunnan, People's Republic of China. Lamellitettigodes palawanicus Günther, 1939 stat. nov. is no longer regarded as a subspecies of L. contractus, but a separate species. Two species are transferred from Euparatettix Hancock, 1904 to Lamellitettigodes: Lamellitettigodes sagittatus (Bolívar, 1887) comb. nov. and Lamellitettigodes cultratus (Bolívar, 1898) comb. nov. One species is transferred from Tetrix Latreille, 1802 to Lamellitettigodes - Lamellitettigodes signatus (Bolívar, 1887) comb. nov. Xistra tricristata sumatrana Bolívar, 1898 syn. nov., Xistra tricristata Bolívar, 1898 syn. nov., and Probolotettix corticolus Blackith & Blackith, 1987 syn. nov. are synonymized with Lamellitettigodes contractus (Bolívar, 1887). Probolotettix kevani Blackith & Blackith, 1987 syn. nov. is synonymized with Euparatettix personatus (Bolívar, 1887). Additionally, in the genus Lamellitettix Hancock, 1904, Lamellitettix acutus Hancock, 1904 stat. rev. is retransferred from a subspecies of Lamellitettix gallinaceus (Stål, 1877) to a separate species status
