Diagnosis. Three known Korean Trupanea species look somewhat similar to Actinoptera species by having a single dark subapical wing spot with rays, but can be readily distinguished by having two pairs of orbital setae and longer pterostigma (about twice as long as wide). Trupanea guttistella is the only Korean member of this genus that has a distinct sexual dimorphism in wing pattern with the subapical star-like wing spot much more extensive in female ( Fig. 9A vs. 9C, E).

Description of Korean material. Wing length 3.9-4.2 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 3 grey frontal setae; anterior orbital seta grey but posterior seta white; ocellar seta grey, distinctly longer than anterior orbital seta. Thorax looks whitish grey due to mostly dark brown ground color with heavy whitish grey pruinosity; postpronotal lobe with yellowish brown ground color; notopleuron with anterior seta grey but posterior seta thick, white, about 2/3 as long as anterior one; anepisternal setae brown with upper seta strong but

lower anepisternal seta about 2/3 as long as upper one; scutellum only with pair of basal setae. Legs yellowish brown with fore femur with 4-5 brownish grey postero-ventral setae; mid coxal seta strong, pale brown. Male wing essentially hyaline on basal half, subapically with single large dark spot with rays; cell r 1 apical to pterostigma hyaline at basal 1/3, remaining area dark brown with large hyaline subbasal round spot leaving narrow basal longitudinal band; cell r 2+ 3 with small anterior hyaline spot connected to r 1 hyaline spot extending r 1 longitudinal dark band, dark area ended subapically with small round hyaline spot at apex of vein R 1; apex of cell r 2 + 3 with small isolated dark spot; basal 2/3 of cell r 4 + 5 largely dark, narrowly hyaline just apical to crossvein R-M, large hyaline spot anterior to crossvein DM-Cu, dark area end- ed at about apical 1/3 without any ray within cell; cell m with 3 narrow rays extended from dark area of cell r 4 +5; 2 more rays recognized at apical 1/3 of cell dm. Female wing with subbasal spot much larger then male; cell r 4 + 5 predominantly dark with basal longitudinal hyaline spot and smaller round hyaline spot close to crossvein DMCu, dark area ends at about apical 1/4 with clear postero-apically directed ray often ends at or slightly into cell m; cell m rays not recognized as in male due to more extended dark area, instead about 3-4 hyaline spots recognized. Abdomen matte whitish grey but ground color dark brown; oviscape shiny dark brown, cone-shaped, about as long as 3 preceding segments.

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

Biology. Unknown.

Remarks. Since the only two Korean specimens available were females, some additional specimens collect- ed from Russian Far East were compared (see Material examined). The new Korean name of this species translates as “sexually dimorphic Trupanea ,” referring to its wing dimorphism.
