DIAGNOSIS. On facies and in genitalia the new species is similar to I. punctigera , but ground colour of wings is usually more intensive brown and black elements in the wing pattern are less bright and slightly fuzzy along the edges. In the male genitalia, right apical process of aedeagus is much narrower, subulate, and left apical process is much shorter, not reaches the half of length of the right apical process; external portion of aedeagus is much shorter, only about 2 time longer of its internal portion; valva with dorsоbasal process more or less gently arched up to the top and with distal margin possesses more of less distinct hump ventrad of the base of dorso-distal process; succus shorter.

DESCRIPTION. Male ( Figs 2–9 ). Wingspan 22–30 мм. Palpae moderately short, about as long as 1/2 of the eye diameter, with second segment oval, somewhat longer than first segment. Proboscis very short, rudimentary. Frons covered with appressed greyish brown scales. Antennae dentate, with moderate fasciculate ciliation, at the middle of antenna the cilia about as long as 2 segments of antenna.

Patagia and tegula garish-light brown, concolorous with thorax and abdomen.

Hindtibia with a pair of median spurs present. Fore wings are light greyish-brown,

sparsely dusted with blackish scales, black elements of the wing pattern somewhat greyish, moderately contrasting and fuzzy along the edges; antemedial line rounded,

blackish points on veins crossing the line weak or almost invisible; postmedial transverse line is smooth or, rarely, slightly wavy, departs from the costal edge of the wing about perpendicular and usually sharply curved outward at the vein M1,

blackish points on veins crossing the line moderately distinct or weak; discal spot vary from a small point to a large oval spot; apical triangular light fleck is usually distinct, widely shaded by dark posteriorly. Hind wings are slightly paler, discal spot dot-like, single postmedial line strongly fuzzy or almost invisible.

Male genitala ( Figs 27–31 ). Uncus is lobe-like with prominent lateral narrowing near the base, moderate by size, its width in the base about the length of dorsobasal process of valva. Valva with a pair of long pointed dorsal process, dorso-basal one is somewhat shorter and much narrower of dorso-distal process, dorso-distal one is gently arched; ventral edge of valva is rounded. Juxta narrow finger-like basally,

dorsal lobes of juxta moderate. Aedeagus 1.0– 1,1 mm in length, almost twice as long as length of ventral margin of valva, cylindrical in basal half and conic in distal half, right apical process of aedeagus narrow and long, sharply pointed,

subulate, left apical process of aedeagus similar by shape, but somewhat narrower and much shorter of the right one. Cornutus in aedeagus large, as big as left apical process of aedeagus, more than 2 tame as long as the diameter of aedeagus. Saccus moderately large.

Female ( Fig. 10 ). Body length 6 mm (dry specimen). Head, thorax and abdomen dark-grey, abdomen ventrally off-white. Hind tibia smoothly dilated distally, with a pair of distal spurs only. Anal tuft composed with mixed long blackish scales of two types: hair-like, and flat very narrow, sharply pointed. Composition of anal tuft scales not differs from that of I. punctigera (see Nakajima, 1992: fig. 45, as “ I.

membranaria ”). Abdomen with tympanal organs lacking.

Female genitalia ( Fig. 32 ). Papillae anales small, simple. Ventral plate between the anal papillae bar-like, dense, long and comparatively wide. Anterior apophyses approximately twice shorter of posterior ones. Genital segment with ventral area membranous, in postvaginal area with small conic semisclerotized hollow (sterigma),

rounded on bottom and placed greatly posterior of ostium. Antrum (“sterigma” of

Nakajima, 1992) is in shape of wide and short truncated cone with almost straight lateral sides, and with dorsal wall bulging ventrally in form of wide longitudinal groove. Colliculum (inflation of ductus bursae just anterior of antrum) slightly bi-

lobed, cervix bursae (rest anterior portion of ductus bursae) long and wide, departs from colliculum at right angle, corpus bursae broad oval, membranous. The antrum and sterigma are similar to those of I. punctigera (see Nakajima, 1992, fig. 40, and

Nakajima, 1998, fig. 274, both as “ I. membranaria ”), but the latter possess less prominent dorsal bulging of antrum and rounded colliculum. However, it is unclear are these differences diagnostic or result of different mounting of the genitalia on slides.

GENETICS. COI “barcode” p-distances between populations from Vladivostok

(4 specimens) ( Table 1) and from vicinity of Zanadvorovka (5 specimens) ( Table 2)

vary from 0.00% up to 0.80%; both sets include specimens with large and small discal spots on the wings. In BOLD, maximum intraspecific p-distance in set included the samples from vicinity of Zanadvorovka and specimen from Sichuan

(ID-unpublished) is 1.17%, and p-distance to nearest neighbor, “ Inurois fletcheri ”

(ID-unpublished and origin is not indicated), is 4.49%.

REMARKS. Specimen in BOLD (2022b) database “GWOTQ472-16{ Inurois }”

from Sichuan well conforms to Russian ones by appearance and close genetically

(BIN BOLD: ACV9571). In GBIF, 5 moths of “ Inurois membranaria Christoph,

1880”, including 1 female, photographed by Shi Qi in Nanjing (iNaturalist, 2022:

GBIF ID 3456340597, 3415969337, 3415613449 and 3415527251), on appearance well conforms to I. pseudopunctigera . Judging from these photos and the photos in

BOLD and in Nakajima & Wang (2014), the Chinese specimens in wing pattern differ by stronger arched antemedial transverse line on costal area of the forewing and, probably, by more dense greyish suffusion. But in the male genitalia

(Nakajima & Wang, 2014: figs 34, 34a, 35, 35a) there are no noticeable differences from Russian specimens. The photo of “ Inurois fletcheri ” from Shaanxi in Zhu

(1981) somewhat indistinct but also seems to represent I. pseudopunctigera ; to be sure, the specimen must be examined.

DISTRIBUTION. Russia (S Khabarovskii Krai NE up to Komsomolsk-na-

Amure), Jewish Autonomous Oblast, Primorskii Krai), S Korea (except islands),

China (Shaanxi, Sichuan, Jiangsu); evidently, it also inhabits at least N Korea and eastern territories of NE China.

analysed in Yamamoto et al. (2016).

BIONOMICS. In the Russian Far East, the moths are usually numerous in broadleaved and mixed forests, emerges from pupae after first ground frosts. In the Pri-

amurye (Khabarovskii Krai, Jewish Autonomous Oblast) moths fly during the 2

first decades of October with peak at the middle of the month. In mountains of the south of Primorskii Krai they also start to fly from early October, but in lowlands from the mid of October and along the southern coast – from the late October, and fly up to mid November with peak at end of October – early November. In mountains of Shaanxi (about 2000 m above sea level) the moths were collected in beginning of November (Nakajima & Wang, 2014), similar to that in the south of

Primorskii Krai, and in the lowland of Jiangsu (Nanjing) they were occurred in beginning January (iNaturalist, 2022). In Primorskii Krai an active flight of the moths was observed at night at air temperatures down to –4°C, but after a warm and sunny day. Wintering eggs. Larvae probably develop on various deciduous woody plants.
