Randomized trial identifies a new genus and species in Asian Tetriginae, highlighting species misclassification in taxonomy.
A new genus, Ingrischana gen. nov. (Tetrigidae: Tetriginae) is established for winged Tetriginae from Asia with extremely setose mid femur, and toothed dorsal margin of the hind femur. Till now, many species of this genus have been erroneously assigned to the genera Bannatettix Zheng, 1993; Formosatettixoides Zheng, 1994; Ergatettix Kirby, 1914; Euparatettix Hancock, 1904; Paratettix Bolívar, 1887, and Tetrix Latreille, 1802. Altogether 2 new species, 11 new combinations, 1 new name, and 2 new synonyms are proposed, and 1 species is reinstated. Two new species are I. motbotawa gen. et sp. nov. (Brija Furry Groundhopper) and I. aspinosa gen. et sp. nov. (Toothless Furry Groundhopper), both from Nepal. New combinations are I. aptera (Zheng et Ou, 2009) comb. nov., I. barbifemura (Zheng, 1998) comb. nov., I. curvimargina (Zheng et Deng, 2004) comb. nov., I. dentifemura (Zheng, Shi et Luo, 2003) comb. nov., I. grossifemura (Zheng et Jiang, 1997) comb. nov., I. longzhouensis (Zheng et Jiang, 2000) comb. nov., I. obesa (Bolívar, 1887) comb. nov., I. serrifemora (Deng, Zheng et Wei, 2008) comb. nov., I. serrifemoralis (Zheng, 1998) comb. nov., I. serrifemoroides (Zheng et Jiang, 2002) comb. nov., and I. torulosinota (Zheng, 1998) comb. nov. The new name is I. parlungana nom. nov., proposed for Bannatettix serrifemoralis Zheng et Shi, 2009a, because of the homonymy with I. serrifemoralis (Zheng, 1998) comb. nov. Ingrischana jhapana (Ingrisch, 2001a) stat. rev. et comb. nov. is reinstated as a valid species. Two new synonyms are Formosatettixoides guangxiensis Zheng & Jiang, 2000 syn. nov. (of I. longzhouensis comb. nov.), and Ergatettix serifemoroides Zheng et Shi, 2009b syn. nov. (of I. parlungana nom. nov.). The new genus is defined not only by morphological apomorphies, but is also confirmed by mitogenome phylogeny.
