Exploring the diversity of Eupolyphaga Chopard, 1929 (Blattodea, Corydioidea): species delimitation based on morphology and molecular analysis
Eupolyphaga Chopard, 1929 is a cockroach genus mainly endemic to China. In this study, the species diversity of this genus is further explored through morphology and molecular analysis. Four species are described new to science: Eupolyphaga miracidia Qiu, sp. nov., Eupolyphaga udenostyla Qiu, sp. nov., Eupolyphaga reducta Qiu, sp. nov., and Eupolyphaga simila Qiu, sp. nov. New knowledge on some known species is added, including new distribution records and characteristics of females. Forty-five COI sequences were newly sequenced and a molecular species delimitation analysis was performed using ABGD method. Eighteen molecular operational taxonomic units were obtained by ABGD analysis, which are nearly consistent with the results of morphological delimitation.
