Thereomyia yunnanica Chao & Zhang, 1988a: 279 . China, Yunnan, Lijiang, Shigu.

Originally included specimen: Described from one male.

Name-bearing type: Holotype ♂: Yunnan, Lijiang, Shigu/ 1900M/ Chinese Academy of Sciences [white label in Chinese, in black print except “Lijiang, Shigu/ 1900M” handwritten in black ink]// 1981. VII.30 / Collected by X.Z. Zhang [“1981. VII.30 ” handwritten in black ink, remaining in black print, in Chinese]// HOLOTYPE [red label, in black print]// IOZ(E)216070 [blue label, in black print]// ♂ [white label, in black print]// Thereomyia / yunnanica Chao et Zhang / Identified by C.M. Chao [“Identified by C.M. Chao” in black print, in Chinese, remaining handwritten in blue-black ink].

Holotype in good condition except left mid leg missing and terminalia extracted.

Current identity: Protomiltogramma yunnanica (Chao & Zhang, 1988) , as correctly listed by Pape (1996) and as treated by Xue & Chao (1998).

Remarks: Chao & Zhang (1988a) compared this species with P. fasciata (Meigen) , but the male terminalia are so different that a confusion is hardly possible (see Rohdendorf, 1935, fig. 65; Povolný & Verves, 1997, fig. 14). Comparisons with habitus photographs and illustrations of terminalia provided for species of Protomiltogramma described recently ( Kurahashi & Chaiwong, 2007; Kurahashi & Leh, 2008) also support considering P. yunnanica as a valid species.

Chao & Zhang (1988a) has two original spellings of the species epithet: yunnanica (p. 279, 287) and yunnaniac (p. 279, in figure caption). We consider the latter to be a simple error, which is in agreement with the use of the spelling Protomiltogramma yunnanicum by Xue & Chao (1998: 1555). In more formal terms the latter may be considered as a First Reviser action under Article 24.2.4 of the International Code of Zoological Nomenclature (ICZN, 1999), where Chao as the original author by using only one of the two original spellings of the species epithet selected Thereomyia yunnanica to be the correct original spelling.

Redescription of Male: Body length 9.3 mm ( Fig. 15 A). Eye bare, red. Fronto-orbital plate, parafacial and postocular strip black with goldenish yellow pollinosity; parafacial with fine bristles, about as broad as frontoorbital plate.
