Diagnosis. This species has an extreme wing sexual dimorphism; male wing tends have more numerous hyaline spots ( Fig. 4C vs. 4E). Males can be easily identified by their unique wing pattern, but females have a typical Campiglossa appearance. They can be separated from any other Korean Campiglossa species by the combination of the following characteristics: 1) thorax mostly pale greyish brown but bases of acrostichal, intra-alar, post-alar, basal scutellar setae with round dark brown spots; 2) both orbital setae dark brown; 3) pterostigma completely dark grey or nearly so in male ( Fig. 4 C-a), but with distinct hyaline spot in female ( Fig. 4 E-a); 4) cell r 1 apical to pterostigma with 5 large hyaline spots in male, but with 4 hyaline spots in female; and 5) area bordered by crossvein R-M (reaching about as far as crossvein length) with at least 7-12 tiny hyaline spots (contrasting well with much larger hyaline spots basal and proximal to them) in male ( Fig. 4 C-b), but that area of female without such tiny spots but with two moderate sized round hyaline spots at base and apex of that area ( Fig. 4 E-b).

Description of Korean material. Wing length 5.0-6.0 mm; most setae on head and thorax strong, dark brown, but most setulae white; body mostly pale yellow ground color with heavy grey pruinosity. Head pale yellowish brown with large and geniculate mouthparts; genal seta strong, dark brown; with two dark brown frontal setae; both orbital setae dark brown; ocellar seta dark brown, distinctly longer than anterior orbital seta. Thorax looks greyish pale brown due to yellowish brown ground color with heavy greyish white pruinosity; bases of acrostichal, intra-alar, post-alar, basal scutellar setae with round dark brown spots; both notopleural setae dark brown; upper anepisternal seta strong and dark brown, but lower anepisternal seta white, about 2/3 as long as upper one; ketepisternal seta strong, dark brown; anepimeral seta strong, white; scutellum with apical setae crossed near apex, about 2/3 as long as basal seta. Legs pale yellowish brown with fore femur with 6-7 brown postero-ventral setae; mid coxal seta strong, white. Male wing dark grey to grey with numerous round hyaline spots in variable sizes; cell c hyaline with dark spot in middle; pterostigma completely dark grey (rarely with tiny hyaline spot); cell r 1 apical to pterostigma with 5 large hyaline spots; cell r 2+ 3 apical to crossvein R-M with two large hyaline spots basally (anterior spot sometimes divided into two spots), plus at least 9 much smaller hyaline spots arranged in 2 irregular rows; cell br apical to crossvein BM-Cu with 3 moderate sized round hyaline spots plus about 5 tiny spot just before crossvein R-M; cell r 4 + 5 before crossvein DMCu with 6-7 tiny hyaline spots, apical to crossvein DMCu with at least 10 larger round hyaline spots; cell m with 6-7 large round hyaline spots. Female wing dark grey with less numerous hyaline spots than male; cell c hyaline with dark spot in middle; pterostigma dark grey with sin-

gle hyaline spot; cell r 1 apical to pterostigma with 4 hyaline spots (but 5 spots in the drawing by Korneyev (1997)); cell r 2 + 3 apical to crossvein R-M with at least 6 hyaline spots; cell br apical to crossvein BM-Cu with 2 round hyaline spot in middle; cell r 4 + 5 with 7-9 round hyaline spots; cell m with 5 moderate sized round hyaline spots. Abdomen mostly greyish pale brown, with pair of large dark brown spots on each of tergite 3-5 (plus tergite 6 in female); oviscape about as long as preceding 3 abdominal segments, shiny reddish brown with dark brown basal and apical areas.
