Taxonomic revision of the praying mantis subfamily Hierodulinae of China (Mantodea: Mantidae)

Species known from China in the praying mantis subfamily Hierodulinae are revised. A new species, Titanodula menglaensis sp. nov. is described. Hierodula tenuidentata Saussure, 1869 and Dracomantis mirofraternus Shcherbakov & Vermeersch, 2020 are newly recorded from China. Two new synonyms are proposed: Titanodula formosana (Giglio-Tos, 1912) = Titanodula fruhstorferi (Werner, 1916), syn. nov. and Hierodula macrodentata Wang, Zhou & Zhang, 2020 = Hierodula latipennis Brunner de Wattenwyl, 1893. Ootheca and male genitalia of the Chinese species are described and photographed. An identification key to genera and species of Hierodulinae from China is also provided. The current Chinese checklist contains 21 species.
