description: 9. Tephritis okera (Shinji, 1940)   
 ǧșŭẖṻƞ ( ṵḍ ) (Fig. 8A- F)   
 Platensia okera Shinji, 1940: 2 (type locality - Japan, Honshu, Iwate Pref., Morioka City; type Shinji).   
 Tephritis okera: Sueyoshi, 1998: 124 (resurrected from synonymy of both T. separata and T. ismene).   
 Tephritis separata (T. okera as erroneous junior synonym): Ito, 1984: 248 (in synonymy of T. separata): Wang, 1998: 302 (in synonymy of T. separata).   
 Tephritis ismene (T. okera as errorneous junior synonym): Korneyev, 1996: 123 (in synonymy of T. ismene); Norrbom et al., 1999: 218 (in synonymy of T. ismene).   
 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 readily distinguished from any other Korean Tephritis species by having a large number of hyaline spots of cells dm and cu 2 as follows (Fig. 8C, E): 1) cell dm with at least 12 hyaline spots recognized; and 2) cell cu 2 with over 20 variously sized hyaline spots.   
 Description of Korean material. Wing length 4.8-5.0 mm; most setae on head and thorax strong, grey, but most setulae white. Head yellowish brown with small normal non-geniculate mouthparts; genal seta strong, pale brown; with two grey frontal setae; anterior orbital seta grey but posterior seta white; ocellar seta 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 grey but posterior seta white, thick, about 2/3 as long as anterior one; both anepisternal setae grey with lower seta about 2/3 as long as upper one; katepisternal seta strong, grey; anepimeral seta strong grey; scutellum with apical setae crossed, about half as long as basal seta. Legs yellowish brown with fore femur with 6-7 pale brown postero-ventral setae; mid coxal seta strong, grey. Wing hyaline, essentially with 2 merged markings - dark antero-medial marking and antero-subapical marking with rays; cell c almost hyaline with pale grey spot in middle; pterostigma completely dark brown except for narrow pale brown postero-basal corner; cell r 1 posterior to cell c hyaline with pale 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) often with tiny hyaline spot antero-medially; cell r 2 + 3 basally with hyaline area, posterior to pterostigma almost completely dark, large and much smaller hyaline spots connected to 2 large hyaline spots of cell r 1, apically with tiny hyaline spot near apex of vein R 2 + 3 plus larger hyaline spot posterior to it; basal half of cell br almost hyaline, posterior half dark with 2-3 small merged hyaline postero-basal spots; cell r 4 + 5 with small round hyaline spot just anterior to crossvein DMCu, 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 rays within cell, basal ray with 2-4 tiny hyaline spots; cell bm almost completely hyaline; cell dm with at least 12 hyaline spots recognized; cell cu 2 with over 20 variously sized hyaline spots; anal lobe also with at least 10 hyaline spots. Abdomen yellowish brown ground color with grey pruinosity; oviscape about as long as or slightly shorter than 3 preceding abdominal segments, shiny brown with basal 1/3 and apical tip dark brown.

Lee, 1$; ditto, 18.VI.2009, Y.B. Lee, 1$. All deposited in YSUW.   
 Distribution. Korea, Japan (Honshu).   
 Biology. This species infests flower heads of Atractylodes japonica Koidz. in Korea (new records) and Japan (Shinji, 1940; Sueyoshi, 1998). In Korea, September collected A. japonica flowers yielded the flies in October of the same year.   
 Remarks. The new Korean name of this species refers to its host plant.
