Assara hoeneella Roesler, 1965

Roesler, 1965: 43–44, figs 27, 178.

Type locality: China, Prov. Chekiang, West Tien-mu-shan .

Material: 1♀ — Russia, Primorsky Krai, 31 km SE of Chuguyevka, Verkhne-Ussuriysky station , 44 ° 22ʺN, 134 ° 12ʺE, h= 590 m, 18.07.2018, S. Yu. Sinev .

Description ( Fig. 1 ). Head rounded, forehead wide, equal to the eye diameter, covered with blackish-brown, slightly protruding scales. Labial palps thin, curved upwards. Antennae simple. Thorax and tegulae blackish brown. Wingspan 17 mm. Forewings blackish brown, its pattern consists of curved light gray basal band, diffuse light gray discal spot, and thin, almost straight, whitish gray postdiscal line. Fringe uniformly blackish-brown. Hindwings unicolorous, gray with brown scales, fringe light gray. Legs light grey.

Female genitalia ( Fig. 2 ). Papillae anales wedge-shaped from lateral view, more than three times shorter than apophyses posteriores and covered with short setae, which only at the base of papillae are longer. Apophyses posteriores more than two times longer than anterior ones. Apophyses anteriores thin, slightly curved apically. Antrum moderately wide, funnel-shaped, smoothly passes into ductus bursae. Ductus bursae membranous without traces of sclerotization, thin, only slightly widened before bursa. Corpus bursae oval, slightly constricted anteriorly. Signum large, consists of several rows of columnar teeth.

Distribution. Russia (Primorsky Krai); China (Liaoning, Hebei, Henan, Tianjin, Shanxi, Zhejiang, Fujian, Jiangsu, Hunan, Hubei, Guizhou, Chongqing, Sichuan), Japan (Honshu, Shikoku, Kyushu) ( Yamanaka et al. 2013; Qi et al. 2014).

Remark. The genus Assara Walker, 1863 , consists of two morphologically distinct groups: the species of the first group are similar in appearance and in the structure of female genitalia with Assara albicostalis Walker, 1863 , the type species of the genus; the second group includes species close to Assara terebrella (Zincken, 1818) . The species of the first group has a more or less contrasting coloration with clearly expressed particularly light elements of the pattern. Besides, female genitalia have a kind of signum in the form of a transverse strip. Of the species found in Russia, Assara korbi (Caradja, 1910) belongs to this group. The species of the second group is characterized by a darker coloration with an indistinct light pattern, and the female genitalia have a more or less rounded signum representing a group of serrated formations, similar with those found in the closely related genus Euzophera Zeller, 1867 (type species: Myelois cinerosella Zeller, 1839 ). In Russian fauna, this group includes the transpalearctic Assara terebrella (Zincken, 1818) and east asian Assara hoeneella Roesler, 1965 . The latter species is very close to Assara funerella (Ragonot, 1901) , which is known from Japan ( Yamanaka et al. 2013) and South Korea ( Bae et al. 2017), but differs considerably in the structure of female genitalia having ductus bursae much longer and not widened before bursa copulatrix.
