description: 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.

Ocellar bristles fine and directed antero-laterally. Gena ground color black, with black bristles, height 0.05× eye height in lateral view (Fig. 15 E). Antenna reddish yellow, not reaching the level of vibrissal insertion, first flagellomere 1.85× as long as pedicel (Fig. 15 C, D); arista bare, with basal half swollen, postocular bristles in 7–9 rows; vibrissa developed. Palpus yellow, not expanded in distal part (Fig. 15 E).
Thorax ground color black; scutum pollinosity yellowish gray.

Pleuron with meropleurals 6 or 7, katepisternal bristles 1: 1(2), prosternum, metasternum and proepisternum bare, postalar wall with 3 or 4 fine bristles.
Wing hyaline; subcostal sclerite and basicosta yellow, bare; tegula black, with black fine bristles; costal spine not differentiated (Fig. 15 A); vein R1 bare, two or three ventral and three dorsal setae at node of R2+3-R4+5, lower calypter yellowish white.
Legs black; fore femur with five rows of long bristles along posterodorsal, posterior, and posteroventral surface, fore tibia with one apical dorsal bristle, fore first tarsomere with spines on the ventral base, without any slender bristle (Fig. 15 G); mid femur with one row of anterior bristles and one row of posterior bristles, two apical posterodorsal bristles, mid tibia with one sub-median anterodorsal, one sub-median ventral, one sub-median posterior and two posterodorsal bristles; hind femur with one row of anterodorsal bristles and several rows of ventral bristles, hind tibia with one row of anterodorsal bristles (about 12) and one row of posterodorsal bristles (about 7), four median ventral bristles.
