Remarks . Comprising 39 described species, Tetanocera is the fourth largest genus of Sciomyzidae . According to Rozkošný (1987) and Vala et al . (2012) , 20 species are known from the Palearctic Region, 30 species are known from the Nearctic Region (with 1 species, T. plumosa , extended into the Neotropical Region), and 2 species are known from the Oriental Region. Before our study, 6 species of Tetanocera ( T. arrogans , T. chosenica , P. elata , T. ferruginea , T. ignota , and T. nigrostriata ) had been recorded from China ( Knutson 1977 ; Rozkošný & Elberg 1984 ; Rozkošný 1987 ; Li, Yang & Gu 2001 ). The type locality of 2 species are in China : P. ignota , whose type locality is Tibet , and T. nigrostriata , whose type locality is Kunming ( Yunnan Province ). During our study we determined about 7 species new to China , bringing to at least 13 the number of species known from China . Although Tetanocera is found in both the Palearctic and Oriental Regions of China , most specimens of Tetanocera in our study were from the Palearctic Region of China . According to the key of Rozkošný (1987) , only T. latifibula Frey, 1924 and T. punctifrons Rondani, 1868 , are both characterized by having 1 preapical seta on the posterior surface of the midfemur. In our study, 49 specimens ( 15 males and 34 females ) were found to have this character, which means that each of the specimens is most likely to be either T. latifibula or T. punctifrons . The 49 specimens were collected both from the Palearctic Region of China , including such areas as Inner Mongolia , Liaoning Province , Hebei Province , and Beijing and from the Oriental Region of China , and including such areas as Sichuan Province , Henan Province (Nanyang, Xinyang), Yunnan Province , Guizhou Province , and Zhejiang Province . Both T. latifibula and T. punctifrons have been reported only from the Palearctic Region before, so our records from the Oriental Region of China indicate that Tetanocera has a more extensive distribution than had been known.
