Pherbellia Robineau-Desvoidy, 1830 ( Figs. 1, 8 , 35–38 , 67 ) Pherbellia Robineau-Desvoidy, 1830: 695 . Type species : Pherbellia vernalis Robineau-Desvoidy, 1830 (monotypy) [= Sciomyza schoenherri Fallén, 1826 ]. Diagnosis . Frons with 2 orbital seta. Prosternum bare. Propleural seta strong. Wing of most species hyaline without spots, of several species with reticulated pattern, and of a few species with infuscation. Remarks . Comprising 95 described species (with 4 described subspecies), Pherbellia is the largest genus of Sciomyzidae . Species diversity is highest in the Palearctic Region, with 50 species, of which 42 are restricted to the Palearctic Region, with the range of 1 species, Pherbellia cinerella ( Fallén, 1820 ) , extending into the Oriental Region. The next highest species diversity is found in the Nearctic Region, with 32 species. Before our study, only 5 species (including 1 subspecies) of Pherbellia were known from the Oriental Region: P. causta (Hendel, 1913) [= Hendel, 1913b ], P. cinerella , P. javana ( Meijere, 1919 ) , P. nana reticulata ( Thomson, 1869 ) , and P. terminalis ( Walker, 1858 ) , and only 6 species (including 1 subspecies) of Pherbellia were known from China : P. brevistriata , P. causta , P. griseola , P. nana reticulata , P. orientalis , and P. terminalis ( Knutson 1977 ; Rozkošný & Elberg 1984 ; Rozkošný 1987 ; Rozkošný & Knutson 1991 ; Li, Yang & Gu 2001 ). The type localities of 3 of these species are in China : P. nana reticulata , from Kwangtung ( Guangdong Province ); P. causta , from Taiwan ; and P. orientalis , from Harbin ( Heilongjiang Province ). As a result of our study, at least 15 species of Pherbellia are now known from China , from both the Palearctic and Oriental Regions. Pherbellia brevistriata Li, Yang & Gu 2001 was described as a new species. Examination of additional specimens during this study convinced us that P. brevistriata is identical to P. nana reticulata ; thus P. brevistriata becomes a junior synonym of P. nana reticulata .

FIGURES 9–16. Characters and morphological terms for the family Sciomyzidae (II). Pherbellia ditoma Steyskal, 1956 is unique among Palearctic species of Pherbellia in having 2 stump veins on M 1+2 . The original description ( Steyskal 1956 ) was based on a male from Andong, Korea (in the Palearctic Region). During our study we determined 1 male P. ditoma from Jiangxi , 1 male from Zhejiang , and 1 female from Inner Mongolia . Located in the south of China , Jiangxi and Zhejiang are typical Oriental Region areas. Thus, in addition to being found in the Palearctic Region ( Vala et al . 2012 ), our study shows for the first time that P. ditoma also is found in the Oriental Region. During our study we discovered 1 female of P. ditoma ( Fig. 35 ), the first female specimen known of this species, from Inner Mongolia . Pherbellia orientalis Rozkošný & Knutson, 1991 was described as a new species on the basis of 1 female from Harbin, Heilongjiang Province , in the north of China (Palearctic Region). During our study we determined 4 males and 3 females from Yueyang, Hunan Province , in the south of China . The male of this species ( Fig. 36 ) was previously unknown. We also report here the first occurrence of this species in the Oriental Region. Pherbellia schoenherri ( Fallén, 1826 ) is one of the few species in this genus with a reticulated wing pattern ( Fig. 38 ). Two described allopatric subspecies are known: P. s. schoenherri ( Fallén, 1826 ) from the Palearctic Region and P. s. maculata ( Cresson, 1920 ) from the Nearctic Region. Collectively, this species (including both subspecies) was known previously from only the Holarctic Region ( Vala et al . 2012 , 2013 ). During our study we identified 2 males and 1 female of this species from Beijing and 2 males and 1 female of this species from Yunnan . The specimens from Yunnan represent the first record of P. schoenherri ( P. s. schoenherri ) from the Oriental Region. Only 2 species in this genus, P. schoenherri and P. cinerella , are known from both the Palearctic and Oriental Regions.
