Type material. Holotype: male, China, “A-tun-tse (N Yunnan), Aus Hohe ca. 3500 m. 7.vii.1937 (H. Höne)”; Genitalia prep. 2089; Paratypes: 3 males, same locality and collector, 18.vii.1936; 15.vii.12.vii. 13.vii.1937 (H. Höne); 5 males, China, “Batang (Tibet). Im Taldes Yangtze (ca. 2800 m), 8.vi, 13.vii, 4.vii, 14.vii, 11.vii.1936 (H. Höne)” [coll. ZFMK]. The type series, including the holotype, is in the collection of Zoological Institute and Museum Alexander Koenig (ZFMK, Bonn, Germany).

Diagnosis. The new species differs from other examined congeners by its uniform dark-brown coloration of body and wings. It is closest to M. djakonovi, but differs by having a narrower valva, narrower and longer coecum, and a more rounded shape of the proximal extension of aedeagus.

Description. Adult (Figs. 15, 16). Wingspan: 21–22 mm. Head, thorax, abdomen and wings dark brown. All crosslines waved, dark-brown, much darker than background. All lines marked in costal area as blackbrown streaks; basal line distinct in costal area, antemedial line waved; medial line broken in separated spots; postmedial line waved, broken; submarginal line with wide brownish-grey border on inner side; subterminal field with waved rufous-brown band; orbicular spot dark-brown; reniform spot brown with dark-brown border; terminal field grey-brown; terminal line as row of short dark transversal streaks separated by paler dots; cilia brown, waved. Male genitalia (Fig. 30). Valva wide, with almost parallel dorsal and ventral margins, oblique and rounded apically; ventral margin of valva deeply constricted medially; sacculus with additional sclerotised medial bar; aedeagus with long coecum; proximal extension of aedeagus rather short, oval. According to the male genitalia, M. hoenei is closest to M. djakonovi . Female unknown.
