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

Abstract

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 novaeguineaesp. nov. from New Guinea and Lamellitettigodes karwinkelisp. 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.

DNA Barcoding of Pygmy Hoppers—The First Comprehensive Overview of the BOLD Systems’ Data Shows Promise for Species Identification

“…The substitution saturation tests run on our data conform with this interpretation. There are still a lot of problems in the taxonomy of Tetrigidae, with many groups requiring reclassification [21][22][23][24]. In the future, a combination of molecular and morphological studies will be required to sort out this family.…”

“…Continuing on the previous point, there is a lack of clear diagnoses for many of the described species and higher taxonomic categories [21], which leads to the lack of identification keys for many taxa [22]. Finally, reference databases such as the OSF [15] sometimes contain multiple different species under a single species (due to unresolved taxonomy or earlier misidentifications), which means that it is often necessary to examine the type specimen to determine relevant diagnostic characters and arrive at a confident identification [23,24]. New species continue to be described, adding to the already strained system [15].…”
