Diagnosis. The new species can be distinguished from other species of the malacobyrsa   -group by the valva ovately enlarged in distal 2/3, the sacculus with dorsal lobe expanded in lunulate shape in distal half, and the juxta with lateral arm bifurcate at apex.

Description. Adult ( Fig. 16 View FIGURES 13−18 ). Forewing length 7.0− 7.5 mm.

Head yellowish white. Labial palpus yellow, first and second segments with scattered blackish brown scales on outside, third segment about 1/2 as long as second segment. Antenna yellow, scape blackish brown on dorsal surface, flagellum ringed with greyish brown.

Thorax brown, mixed with yellow; tegula yellow, mixed with brown at base. Forewing with costal margin obviously arched, apex produced, termen obliquely truncate; yellow, with dense brown scales; median fascia blackish brown, indistinctly extending from below middle of costal margin to end of fold on dorsum; discal, discocellular and plical spots blackish brown; series of black dots extending along distal half of costal margin and along termen to tornus; fringe yellow. Hindwing and fringe brown. Legs yellow; on ventral surface, fore- and midlegs black, fore tibia mixed with yellow, mid tibia yellow apically, tarsi of fore- and midlegs yellow at apices of basal two tarsomeres, hind tibia mixed with sparse blackish brown scales, tarsus black, yellow at apex of each tarsomere.

Male genitalia ( Fig. 32 View FIGURES 29−34 ). Uncus very broad at base, gradually narrowed to middle, sharply narrowed and parallel from middle to basal 3/4, then narrowed triangularly to pointed apex, with a long seta at distal 1/4 laterally. Tegumen widened medially, widest more than 1.5 times length of uncus. Valva with basal 1/3 narrow, handle-shaped, distal 2/3 expanded ovately, densely setose, obtusely angled beyond basal 1/3 on ventral margin; costa concave basally, basal 2/3 wide, distal 1/3 narrowed, reaching before apex of valva; transtilla dilated sub-ovately, with long setae. Sacculus short and broad, apically concave inwardly, forming two lobes: dorsal lobe narrowed medially, distal half dilated in lunulate shape; ventral lobe shorter, triangular. Saccus triangular, pointed at apex. Juxta U-shaped; lateral arm bifurcate at apex. Aedeagus shorter than valva, widened from narrow base to basal 1/3, bifurcate in distal 2/3: dorsal branch with tiny teeth on basal half, ventral branch with a spine arising from near base.

Female unknown.

Distribution. China (Fujian, Hainan).

Etymology. The specific epithet of the new species is derived from the Latin lunulatus, referring to the dorsal lobe of the sacculus dilated in lunulate shape distally.
