Twenty-three new synonyms of the Eastern common groundhopper, Tetrixjaponica (Bolívar, 1887) (Orthoptera, Tetrigidae).

ABSTRACT

The Eastern common groundhopper, Tetrixjaponica, is a pygmy grasshopper species widely distributed in the Eastern Palearctic region, and shows a high degree of phenotypic variation. The classification of Tetrixjaponica is difficult and frequently involved errors. Among the many species of Tetrigidae that have been described in China within the last decades, many synonyms of Tetrixjaponica were found. The type specimens of many species deposited in the Chinese museums have been re-examined and as a result, Tetrixjaponica is systematically revised. Based on the results of this review, 23 new synonyms of Tetrixjaponica are proposed Coptotettixcircinihumerus Zheng & Deng, 2004, syn. nov.; Coptotettixemeiensis Zheng, Lin & Zhang, 2012, syn. nov.; Euparatettixrongshuiensis Zheng, 2005, syn. nov.; Euparatettixzayuensis Zheng, Zeng & Ou, 2011, syn. nov.; Macromotettixnigritubercle Zheng & Jiang, 2006, syn. nov.; Macromotettixyaoshanensis Zheng & Jiang, 2000, syn. nov.; Tetrixalbistriatus Yao & Zheng, 2006, syn. nov.; Tetrixalbomaculatus Zheng & Jiang, 2006, syn. nov.; Tetrixalbomarginis Zheng & Nie, 2005, syn. nov.; Tetrixcenwanglaoshana Zheng, Jiang & Liu, 2005, syn. nov.; Tetrixcliva Zheng & Deng, 2004, syn. nov.; Tetrixduolunensis Zheng, 1996, syn. nov.; Tetrixgrossovalva Zheng, 1994, syn. nov.; Tetrixjiuwanshanensis Zheng, 2005, syn. nov.; Tetrixlatipalpa Cao & Zheng, 2011, syn. nov.; Tetrixliuwanshanensis Deng, Zheng & Wei, 2007, syn. nov.; Tetrixqinlingensis Zheng, Huo & Zhang, 2000, syn. nov.; Tetrixrectimargina Zheng & Jiang, 2004, syn. nov.; Tetrixruyuanensis Liang, 1998, syn. nov.; Tetrixxianensis Zheng, 1996, syn. nov.; Tetrixxinchengensis Deng, Zheng & Wei, 2007, syn. nov.; Tetrixyunlongensis Zheng & Mao, 2002, syn. nov.; Tetrixzhoushanensis Gao, Liu & Yin, 2022, syn. nov. It is expected that there will be the discoveries of more synonyms of this and other Tetriginae species from the Eastern Palearctic.
