Abstract

The antlion genus Epacanthaclisis of the subfamily Dendroleontinae is herein revised. A total of 22 species (including 11 new species) are recorded from East to Central Asia and classified into four species groups: 1) the E. continentalis group: E. alaica Krivokhatsky, 1998, E. continentalis Esben-Petersen, 1935, E. darman Zheng, Badano, U. Aspöck, H. Aspöck & Liu sp. nov., E. hamata Krivokhatsky, 1998, E. kuldurguch Krivokhatsky, 1998, E. liuyingqiae Zheng, Badano, U. Aspöck, H. Aspöck & Liu sp. nov., E. victor Badano, Zheng & Liu sp. nov., E. zhiweii Zheng, Badano, U. Aspöck, H. Aspöck & Liu sp. nov., and E. zuqii Zheng, Badano, U. Aspöck, H. Aspöck & Liu sp. nov.; 2) the E. tuyuezhengi group: E. tuyuezhengi Zheng & Liu sp. nov., E. zhihaoi Zheng & Liu sp. nov.; 3) the E. maculosa group: E. jiazhii Zheng, U. Aspöck, H. Aspöck, Hayashi & Liu sp. nov., E. maculata (Yang, 1986), E. maculosa (Yang, 1986), E. minana (Yang, 1999), E. wuchaoi Zheng, Badano & Liu sp. nov., and E. xiaohongae Zheng & Liu sp. nov.; 4) the E. moiwana group: E. banksi Krivokhatsky, 1998, E. longwai Zheng, Hayashi & Liu sp. nov., E. moiwana (Okamoto, 1905), and E. ningshana Wan & Wang, 2010. Besides, E. batangana Yang, 1992, is not assigned to any species group. E. amydrovittata Wan & Wang, 2010 syn. nov. and E. samarkandica Krivokhatsky, 1998 syn. nov. are respectively synonymized as E. banksi and E. continentalis. Immature stages of five species (E. zuqii sp. nov., E. jiazhii sp. nov., E. minana, E. banksi, and E. ningshana) from China are reported after identification through rearing and COI barcoding. A key to the species of Epacanthaclisis is provided. The specialized morphological characters, systematic position, distribution pattern, and biology of Epacanthaclisis are discussed.
