Redefinition of Cornexcisia Fan amp; Kano, 2000 (Diptera: Sarcophagidae), with the first description of the female of Sarcophaga kurahashii (Shinonaga amp; Tumrasvin, 1979).

Abstract

Sarcophaga Meigen, 1826 is proposed as a senior synonym of Cornexcisia Fan Kano, 2000, syn. nov. and Fanzideia Xue, Verves Du, 2011, syn. nov. Cornexcisia Fan Kano, 2000, stat. rev. is given status as a subgenus and is considered a senior synonym of Fanzideia Xue, Verves Du, 2011, syn. nov. at the subgeneric level. Cornexcisia is argued to contain S. (Cornexcisia) longicornuta (Fan Kano, 2000), comb. nov., S. (C.) cygnocerca (Xue, Verves Du, 2011), comb. nov., S. (C.) kurahashii (Shinonaga Tumrasvin, 1979), subgen. comb. nov. (from Phallosphaera Rohdendorf) and S. (C.) suthep Pape Bänziger, 2003, subgen. comb. nov. (from Rosellea Rohdendorf). Sarcophaga (C.) kurahashii is newly recorded from China (Yunnan), the male is redescribed and the female is described for the first time, supported by photographs, illustrations and mitochondrial cytochrome oxidase subunit I (COI) gene sequences. Species of Cornexcisia share an exceptionally long postpedicel in the female and the following apomorphic distiphallic appendages in the male: juxta ventro-proximally with an apically divided arm with cuticular pile, and lateral styli bifurcated from the base with each branch elongate, gently curved and slightly expanded apically. A key to the species of Cornexcisia is provided.
