Diagnosis.
This light-colored species can be diagnosed by the following characteristics. Head largely yellow-brown with grey upper occiput. Thorax with scutum entirely matte whitish grey without any outstanding dark spots or stripes; scutellum mostly matte whitish grey but ca. apical 1/3 yellow-brown. Legs entirely yellowish brown without any dark marking; fore femur with six or seven strong, brown postero-ventral setae. Wing with basal area (basal 1/3 anteriorly and basal 1/2 posteriorly) largely hyaline with only few small dark spots, especially cell br with area posterior to fork of vein Rs completely hyaline ( Fig. 4A-a View Figure 4 ); male with large dark mid-anterior marking covering from mid-anterior 1/3 to posterior end of crossvein R-M; pterostigma dark brown with large round hyaline spot in both sexes ( Fig. 4A-b View Figure 4 ; in the other misella group species this spot tends to be smaller or missing in male); cell r1 posterior to pterostigma with two large hyaline spots (sometimes with tiny additional basal spot, Fig. 4A-c View Figure 4 ) in male and three large hyaline spots in female; cell r2+3 without posteroapical hyaline spot. Abdomen matte whitish grey with tergites 3-5 in male and 3-6 in female each with pair of pale brown submedian spots; oviscape shiny dark brown, as long as three preceding segments.
This species appears similar to C. pishanica (with only males known) but the latter species can be readily separated by the dark femora and more extensive mid-anterior wing marking with pterostigma completely dark ( Figs 4A, C View Figure 4 vs. 10E).

Distribution.
Nepal, China (Yunnan).
Remarks.
The male wing pattern of C. coei is atypical for the genus Campiglossa ( Fig. 4A, C View Figure 4 ), and that is probably why this species, based on a single male specimen, was originally classified as Tephritis by Hardy (1964). Since then, Wang (1998), under this name, recorded two males from Yunnan, China. More recently, Ito (2011) described a new species ( C. favillacea syn. nov.) based on the male holotype (from the type locality of C. coei ) and two female paratypes ( Fig. 10A, B View Figure 10 ), but he did not mention their wing dimorphism in the description. We, fortunately, were able to collect over a hundred male and female specimens from China, showing a remarkable sexual wing dimorphism ( Fig. 4A, C View Figure 4 vs. Fig. 4D, F View Figure 4 ). Most of the specimens were collected along with at least ten other species of the subfamily Tephritinae from a small hilltop in Yunnan, China ( Fig. 3 View Figure 3 ; Mengsong, Manlvcunhanzudazhai, 22°07'44.0"N, 100°28'51.7"E, 1690 m, 12 July 2011). This hilltop appears to be a temporary Tephritinae hot spot due to the clearing of a small forest patch.
