Abstract
A new species of the genus Capnia, Capnia yunnana sp. nov., is described as new to science from Yunnan Province, Southwestern China. Its relationship with closely related species is discussed. Capnia Pictet, 1841 is the largest capniid genus with 117species from the Holarctic and Oriental Regions (DeWalt et al. 2010). The following five species are known from China: Capnia cordata Kimmins, 1947; C. montivaga Kimmins, 1947; C. pedes tris Kimmins, 1947; C. qilianshana Li & Yang, 2009; and C. tibetanaKimmins, 1947 (Kimmins 1947, Harper 1977, Jewett 1975, Li & Yang 2009, Zwick & Sivec 1980, Sivec 1981). In the present paper, a new Capnia species, C. yunnana sp. nov., is described from Yunnan Province. An updated key to males of the genus Capnia from China is provided. The studied material is deposited in the Insect Collection of Henan Institute of Science and Technology (HIST) and Entomological Museum of China Agricultural University (CAU), Beijing, and all of the specimens are preserved in 95% ethanol. The morphological terminology follows that of Nelson & Baumann (1989) and Baumann et al. (1977).
