(Figs 2, 3)
Type material. China, Xizang Autonomous Region: Holotype ♂, Mêdog County (29.33°N, 95.33°E), 1016 m, 4- VIII-2018, leg. Mujie Qi, genitalia slide No. QMJ19090.
Paratype: 1 ♂, Dexing (29.32°N, 95.30°E), Mêdog County, 833 m, 18-VIII-2017, leg. Mujie Qi, Xiaofei Yang, genitalia slide No. QMJ19089.
Diagnosis. This species is most similar to M. carinata Qi, Bae & Li, 2019 in the male genitalia, but it can be distinguished from the latter by the process at base of the sacculus about 2/5 the length of the uncus, dorsalmedial edge of the process dentate, and the ridge connecting apex of the sacculus and base of the costa without strong hairs. In M. carinata (Fig. 4), the process at base of the sacculus is as long as the uncus, the dorsalmedial edge of the process is not dentate, and the ridge connecting the apex of the sacculus and the base of the costa bears strong hairs on its inner 1/2.
Description. Adult male (Fig. 2) wingspan 16.0– 17.5 mm. Frons and vertex covered with yellowish-brown scales, slightly mixed with fuscous and reddish brown. Labial palpus fuscous, mixed with brownish-yellow scales on outer side, brownish yellow on inner side, first segment about 1/3 length of second, third segment slightly shorter than first. Maxillary palpus brownish yellow, almost as long as third segment of labial palpus. Proboscis with fuscous scales at base. Antenna with scape dilated, brownish yellow dorsally, fuscous ventrally, with length about 3.5 times of width; flagellum yellowish brown dorsally, fuscous ventrally. Patagium fuscous, mixed with reddish brown scales slightly; tegula fuscous. Forelegs fuscous, tibia suffused with brownish-yellow scales slightly; midlegs fuscous, tibia covered with fuscous, long hairs; hindlegs with femur fuscous, suffused with brownish-yellow scales, tibia brownish yellow, suffused with fuscous scales slightly, spurs almost fuscous on outer side, tarsus pale yellow. Forewing fuscous; basal and median areas with anterior 1/5 reddish brown along costa; costal margin fuscous, interrupted by several pale yellow spots at median area; antemedial line pale yellow and sinuous, oblique outward from basal 2/5 of costa to basal 2/5 of dorsum, anterior part enlarged into a flat triangular patch at costa; postmedial line pale yellow, discontinuous and represented by small pale yellow dots, from distal 1/6 of costa to distal 1/8 of dorsum, strongly arched outwardly at middle, anterior part enlarged into a bean-shaped patch at costa; fringe fuscous. Hindwing concolorous with forewing; ante- and postmedial lines pale yellow, sinuous and discontinuous; postmedial line distinct on ventral side of hindwing; fringe fuscous.
Male genitalia (Fig. 3) Uncus rounded distally, basal 1/3 expanded and gradually narrows, distal 2/3 with both lateral sides parallel, sparsely setose laterally. Gnathos with lateral arm slim and band-shaped, distal process hooked at apex, about 2/3 length of uncus. Valva with basal half smooth, distal half triangular and hairy; sacculus bandlike, a shorter, sclerotized, bifurcated process arising from its base, about 1/5 length of sacculus, dorsalmedial edge dentate; a ridge with hairs sparsely connecting apex of sacculus and base of costa, with a short thorn-like process at apex of ridge. Juxta tongue-shaped, about 2/5 length of sacculus, scobinate medially, slightly cleft posteriorly. Saccus cone-shaped, rounded anteriorly, as long as sacculus. Phallus cylindrical, slightly longer than valva, cornuti composed of a row of 12–15 thorns.
Female Unknown.
Distribution. China (Xizang).
Etymology. The specific name is derived from the Latin longi (long) and saccus (saccus), in reference to the large size of saccus in male genitalia.
