Diagnosis. Head yellow, vertex inflated with four longitudinal big black marks medially and four transverse black marks laterally; pronotum yellow or pale brown, with two brown, short longitudinal stripes on anterior part of pronotum and two brown, thin bands near posterior margin; abdomen yellow or pale brown; two lateral stems of mediuncus in male genitalia weakly sclerotized and slightly curved.
Description. Male: forewing 28–32 mm, hind wing 23–27 mm, body length 23–34 mm; female: forewing 30–38 mm, hind wing 24–30 mm, body length 25–35 mm.
Head: Yellow, vertex inflated with four longitudinal big black marks medially and four transverse black marks laterally (Fig. 4). Compound eye dark; frons black, area between antennae brown to pale brown. Face yellow with two black spots connecting in the middle; labrum yellow with two black spots proximate to each other (Fig. 5). Maxillary palpus brown to dark brown except pale brown at base; labial palpus thin and long, pale brown on mesal surface and dark brown on lateral surface, terminal segment long and spindle-shaped. Antenna clavate; scape pale brown, pedicel and flagellum dark brown. Thorax: Pronotum grayish yellow with sparse black and white short setae. Two brown short longitudinal stripes on anterior part of pronotum and two brown thin bands near posterior margin (Fig. 6); Mesothorax and metathorax brown yellow to pale brown with brown lateral stripes proximate to wings, middle of metathorax with an orange to black transverse stripe. Legs: Long and slender, yellow or pale brown with sparse black setae and dense short setae. 5th tarsomere longer than 1st tarsomere; tibial spur reaching end of first tarsomere; claw and tibial spurs brown or dark brown. Wings: Hyaline; venation pale brown. Forewing (Fig. 1): Sc and R dark brown alternating with pale brown; anastomosis of Sc and R dark brown; four cross veins between R and Rs dark brown; 6–7 cross veins between M and CuA dark brown; anastomosis of CuA2 and CuP+1A dark brown; costal area with only one row of cells, some cross veins mainly near stigma with a small fork; eight presectoral cross veins; CuA2 parallel along CuP+1A for considerable distance; posterior Banksian line distinct. Hindwing (Fig. 2): Sc and R dark brown alternating with pale brown in basal 2/ 3 to 3/4 portion; two cross veins between R and Rs dark brown; 2–3 cross veins between M and CuA1 brown, inconspicuous; anastomosis of CuA2 and CuP+1A brown, inconspicuous, in some cases these small spots much less evident; CuA2 parallel along CuP+1A for considerable distance; posterior Banksian line distinct. Male with pilula axillaxis. Abdomen: Shorter than hind wing; yellow or pale brown; terminal portion darker; hind edge of each segment paler. Female genitalia (Figs. 7–8): 8th sternite tapering posteriorly, anterior gonapophyses fingerlike, posterior gonapophyses short and wide, lateral gonapophyses tapering anteriorly. Male genitalia (Figs. 9–11): Gonarcus arcshaped, strongly sclerotized. Mediuncus bridge-shaped, two stems short, slender, weakly sclerotized, middle stem long, strongly sclerotized. Parameres auriculate, subacuminate terminally.
Distribution. China: Shanxi, Ningxia.
Remarks. Euroleon flavicorpus sp. nov. is very similar to E. coreanus but can be distinguished by body color, pattern of pronotum and male genitalia. The morphological characters and behavior of the larvae of E. coreanus and E. flavicorpus sp. nov. are similar, but the body color of E. coreanus is darker than that of flavicorpus sp. nov.
Etymology: flav - L. yellow; -corpus L. body; referring to the body color is mainly yellow.
