Diagnosis. The new species is similar to M. quercea Moriuti, 1973 and M. latipterophora Li et Wang, 2004 in the forewing having an inverted trapezoidal fascia, and the anellus with a posterior process in the male genitalia. It can be distinguished from the latter two species in the forewing lacking a yellow costal spot, and the tegumen without a process in the male genitalia; in the latter two species, the forewing has a yellow spot at basal 4/5 of the costal margin, and the tegumen has a long process near the right anterolateral corner.
Description. Adult ( Fig. 15 View FIGURES 12‒17 ). Wingspan 14.0– 15.5 mm.
Head with frons pale yellow, vertex fulvous. Antenna light fulvous; scape white terminally, flagellum ringed with white on dorsal surface. Labial palpus pale yellow, with brown scales.
Thorax and tegula brown. Forewing brown; broad lemon yellow fascia from between basal 1/6 and 1/2 of costal margin extending to dorsum, inverted trapezoidal, with a small yellowish-brown dot on its costal margin, inner margin straight, outer margin slightly oblique inward; fringe yellowish brown. Hindwing and fringe fawn. Foreand midlegs yellowish brown, except tibia ringed with white at basal 1/3, 2/3 and apex dorsally, tarsus mixed with white basally on outer surface; hindleg with femur and tibia sand beige, tibia with gray brown scales at base on outer surface, tarsus pale yellow mixed with grayish brown on inner side, yellowish brown on outer side.
Male genitalia ( Fig 32 View FIGURES 30‒33 ). Socius gradually narrowed to pointed apex. Tegumen sub-trapezoidal. Vinculum narrowly banded. Valva asymmetrical: left valva with basal half wide, convex semicircularly and with short dense setae on ventral margin, sharply narrowed beyond middle, thereafter almost uniformly slender to apex, with dense short spines in distal 1/4; valvella clubbed, 3/4 length of valva, distal half broadened ovally, with setae at apex. Right valva much stronger, broadened towards apex, apex setose, obliquely truncate, produced dorsoapically; valvella shorter, basal half broad, distinctly narrowed to pointed apex from beyond middle, lined with setae in distal half on dorsal margin and around apex. Anellus with a clubbed posterior process, shorter than socius, with a cluster of bristles apically. Aedeagus tubular in basal 4/5, with clustered fine spines from 2/5 to 4/5; cornuti being a bunch of strong spines running from beyond middle to apex and a cluster of a few spines at apex.
Female genitalia ( Fig. 43 View FIGURES 40‒44 ). Apophyses posteriores about twice as long as apophyses anteriores. Seventh sternite with dense setae on posterior margin. Lamella postvaginalis sub-rectangular; lamella antevaginalis large, irregular in shape, with anterior margin acutely angular. Ductus bursae membranous, slightly longer than anterior apophyses; accessory bursae sclerotized posteriorly. Corpus bursae large, with a circular plate full of reticular striae; paired signa each being a circular plate with a small spine, sunken.
Distribution. China (Chongqing, Guangdong, Hainan).
Etymology. The specific epithet of the new species is derived from the Latin reticulatus and Stria, referring to the circular plate of the corpus bursae full of reticular striae in the female genitalia.
