Jankowskia athleta Oberthür, 1884 , Études ent. 9: 25, pl. 2, fig. 7. Syntypes, [ Russia]: Sidemi. (ZFMK) Boarmia (Jankowskia) athleta: Wehrli, 1941 , in Seitz, Gross-Schmett. Erde 4 (Suppl.): 469, pl. 41: e, f.

Diagnosis. This species is similar to J. taiwanensis and J. fuscaria in: the forewing outer margin is straight, the postmedial line is strongly protruded outwards between M1 and M2; the hindwing basal area is pale greyish brown; the tegumen posterior processes of male genitalia are digitiform, each with a bundle of long setae apically; the valva is broadened terminally, bearing two cluster of long setae near center, extending dorsally and ventrally respectively. But from the wing patterns, J. athleta can be distinguished by the indistinct and narrower medial line on hindwing. In the male genitalia, the tegumen posterior processes are very long, about four-fifths length of the uncus; the gnathos median process is shorter and broader, almost flat apically, about one-half length of the basal width; the juxta is almost symmetrical, with a small slightly sclerotized central process. In the female genitalia ( Sato, 1980), the ductus bursae is shorter; the signum is almost hexagon.

Distribution. China (Heilongjiang, Jilin, Henan, Shaanxi, Hubei, Jiangxi, Guangdong, Guizhou), Russia (Ussuri, Amur), North Korea, South Korea.

Remarks. Boarmia (Jankowskia) athleta geloi was recorded in Jiangsu, Zhejiang and Hunan provinces of China, by the description of Wehrli (1941). Later, Zhu (1981) considered these three provinces as the distribution of J. athleta . However, Boarmia (Jankowskia) athleta geloi was designated as a junior synonym of J. fuscaria fuscaria by Sato (1980). Thus, J. athleta is not reported from Jiangsu, Zhejiang and Hunan provinces of China in our study.
