Tephritis jocaste Hering, 1953: 11 (type locality - China, Manchuria, Chandaochezsy; holotype ♂, BMNH); Wang, 1998: 292, 298 (in East Asian Tephriris key; diagnosis and distribution); Norrbom et al., 1999: 217 (in world catalog).

Tephritis n. sp. near separata : Han and Kwon, 2000: 68 (in Korean Tephritis key).

Diagnosis. This is a typical looking Tephritis having two large dark wing markings joined each other: antero-medial marking and antero-subapical marking with rays. It can be distinguished from any other Korean Tephritis species by the combination of the following characteristics: 1) thorax and abdomen yellowish brown ground color with grey pruinosity; 2) legs yellowish brown; 3) oviscape yellowish brown with dark brown basal and apical areas, about as long as two preceding tergites; 4) apical dark area of wing cell r 1 without any hyaline spot ( Fig. 7 C-a; see Fig. 8C for comparison); 5) cell r 2 + 3 just beyond apex of vein R 2 + 3 with moderate sized hyaline spot ( Fig. 7 C-b); 6) basal 1/3 of cell dm completely hyaline ( Fig. 7 C-c); and 7) cell cu 2 with about 10 largely overlapping hyaline spots leaving only some small dark spots.

Description of Korean material. Wing length 4.2-4.5 mm; most setae on head and thorax strong, grey to dark grey, but most setulae white. Head yellowish brown with small normal non-geniculate mouthparts; genal seta strong, pale brown; with two dark grey frontal setae; anterior orbital seta dark grey but posterior seta white; ocellar seta dark grey, distinctly longer than anterior orbital seta. Thorax looks matte pale brownish grey due to yellowish brown ground color with grey pruinosity; notopleuron with anterior seta strong, dark grey, but posterior seta thick and white, about 2/3 as long as anterior one; anepisternal setae dark grey with upper seta strong but lower seta about 2/3 as long as upper one; katepisternal seta strong, grey; anepimeral seta strong pale grey to grey; scutellum with apical setae crossed, about 2/3 as long as basal seta. Legs yellowish brown with fore femur with 6-7 pale grey postero-ventral setae; mid coxal seta strong, pale grey. Wing hyaline, essentially with 2 large dark merged markings - antero-medial marking and antero-subapical marking with rays; cell c almost hyaline with faint greyish spot in middle; pterostigma completely dark brown; cell r 1 posterior to cell c hyaline with grey spot, posterior to pterostigma completely dark, but, apical to pterostigma with 2 large hyaline areas divided by narrow longitudinal dark band, apical dark area (slightly smaller than pterostigma) without any hyaline spot; cell r 2 + 3 basally with hyaline area, posterior to pterostigma almost completely dark brown, large and much smaller hyaline spots connected to 2 large hyaline spots of cell r 1; cell r 2 + 3 with tiny hyaline spot just beyond apex of vein R 2 + 3 plus large hyaline spot posterior to it; basal 2/3 of cell br almost hyaline, posterior 1/3 dark grey with 2-4 tiny hyaline spots; cell r 4 + 5 often with tiny hyaline spot connected to large apical hyaline spot of r 2 +3, large round hyaline spot posterior to it, apically with lying Y-ray ended across veins R 2+ 3 and R 4+ 5; cell m basically with 3 large hyaline spots, leaving 4 dark vertical rays within cell, basal hyaline spot often divided into 2; cell bm completely hyaline; basal 1/3 of cell dm completely hyaline; posterior 2/3 grey to dark grey with 5-7 hyaline spots recognized; cell cu 2 with about 10 largely overlapping hyaline spots leaving only some small dark spots; anal cell anteriorly with 2-3 faint grey spots, posteriorly almost hyaline. Abdomen pale brownish grey; oviscape about as long as preceding 2 abdominal segments, shiny yellowish brown with basal 1/3 and apex dark brown.

Distribution. Korea, China (Heilongjiang), Russian Far East.

Biology. In Korea, I have reared a number of flies from the fall collected (September to October) flowers of Saussurea pulchella Fisch. [ Asteraceae ] (new record). Flies have emerged between mid-October and mid-November of the same year.

Remarks. The new Korean name of this species refers to the above host plant.
