Zhang, Dong, Zhang, Ming, Li, Zijuan & Pape, Thomas, 2015, The Sarcophagidae (Insecta: Diptera) described by Chien-ming Chao and Xue-zhong Zhang, Zootaxa 3946 (4), pp. 451-509 : 468-471

Senotainia ( s. str .) mongolica Chao & Zhang, 1988a: 279 . China, Neimenggu, Tomortei.

Originally included specimens: Described from one male and one female.

Name-bearing type: Holotype ♂: Tomortei, “little flower”/ 1971. VIII.13 [“Tomortei, ‘Weixinghua’/ 1971. VIII.13 ” handwritten in black ink, in Chinese]// Collected by C.M. Chao [in black print, in Chinese]// HOLOTYPE [red label, in black print]// IOZ(E)216071 [blue label, in black print]// ♂ [white label, in black print] // Senotainia / ( S. str ) / mongolica / Zhao & Zhang [white label, in black print]// Senotainia / mongolica 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 dusty, with a break in the right wing and right hind tarsus missing, terminalia extracted.

Current identity: Senotainia fani Verves, 1994 , as correctly listed by Pape (1996) and as treated by Xue & Chao (1998, as S. neimengguensis ). Senotainia ( s. str .) mongolica Chao & Zhang, 1988 is a junior primary homonym of S. mongolica Rohdendorf & Verves, 1980 . Verves (1994) provided a new replacement name for this species. Xue & Chao (1998) also gave a new replacement name for this species, as “ Senotainia neimengguensis Chao & Zhang ”.

Additional type specimen: Allotype ♀: Neimenggu, Tomortei, 13.VIII.1971, Coll. by C.M. Chao. Specimen in NZMC.

Remarks: The holotype and allotype are labeled: ODzw (Weixinghua) meaning “little flower”, possibly indicating that the specimens were collected while visiting flowers. This species is related to S. ( s. str .) conica (Fallén) , but differentiated from it by the male sternite 5 having short bristles on the posterior margin ( S. conica with long bristles on the posterior margin), surstylus long and slender, bow-shaped, the apex of phallus bent backwards (the similar S. conica has a straight phallus).

Redescription of Male: Body length 4.9 mm ( Fig. 10 A). Eye bare, deep red. Fronto-orbital plate, parafacial and postocular strip yellowish black with silvery pollinosity; parafacial bare, 1.6× as broad as fronto-orbital plate. Frontal vitta yellow, 1.3× as broad as fronto-orbital plate at the narrowest point; frons at vertex 0.35× head width ( Fig. 10 C); frontal row of 6 bristles; outer vertical bristle differentiated from postocular bristles, one upper and two proclinate orbital bristles. Ocellar bristles directed antero-laterally. Gena ground color black, with sparse and short black bristles and silvery gray pollinosity, height 0.14× eye height in lateral view ( Fig. 10 E). Antenna brown, not reaching the level of vibrissal insertion, first flagellomere 1.6× as long as pedicel ( Fig. 10 C); arista bare, postocular bristles in three rows; vibrissa developed. Palpus brown, slightly expanded in distal part ( Fig. 10 E).

Thorax ground color black with gray pollinosity, without black dorsal vittae. Chaetotaxy: acrostichals 1+1, dorsocentrals 2+3, intra-alars 0+2, supra-alars 1, postalars 2, postpronotals 2, notopleurals 2, scutellum with 1 apical, 1 marginal, 1 basal and 1 discal bristles. Pleuron with meropleurals 4, katepisternal bristles 1: 1, prosternum, metasternum, proepisternum and postalar wall all bare.

Wing hyaline ( Fig. 10 A); subcostal sclerite and basicosta yellow, bare; tegula black; costal spine not differentiated; vein R1 bare, one dorsal black bristle at node of R2+3-R4+5, lower calypter white.

Legs black; fore femur with one row of dorsal bristles, one row of ventral bristles, one row of posterior bristles and one row of posterodorsal bristles, fore tibia with one apical dorsal bristle, fore first tarsomere with seveal strong bristles on the base of ventral margin, without any elongated, slender bristles on fore tarsomeres 1–4 ( Fig. 10 G); mid tibia with one apical dorsal, one sub-median anterodorsal, one sub-median posterior and one sub-median posterodorsal bristles; hind femur with one row of anterodorsal bristles, hind tibia with one median posterodorsal and two anteroventral bristles, one row of anterodorsal bristles (4 or 5).

Abdomen long oval with gray pollinosity; tergites 1+2, tergites 3 and 4 each with indistinct yellowish black spots laterally, tergites 1+2 with strong marginal bristles, tergites 3 and 4 both with one pair of strong median marginal bristles, sternite 5 with short bristles on the posterior margin ( Fig. 10 F). Terminalia: Pregonite longer than postgonite, the distal part of phallus bent backwards ( Fig. 10 B).

Redescription of Female: Body length 4.4 mm ( Fig. 11 A). Parafacial with four or five fine black bristles, 1.4× as broad as fronto-orbital plate ( Fig. 11 C). Postocular bristles in one row. Thorax with yellowish gray pollinosity. Postalar wall with one black bristle. Fore femur with one row of sparse anteroventral bristles and without posterodorsal bristle row, fore tibia with one sub-median posterior bristle; mid femur with one median ventral and three median posterodorsal bristles; hind femur with three median anterodorsal bristles, hind tibia with one apical dorsal bristles. Other morphological characteristics are similar to those of the male.
