Diagnosis. The new species is similar to M. forcipata sp. nov. It can be distinguished in the male genitalia by the apex-truncate valva without a denticle on the ventral margin, the sacculus produced to a papillary process apically, and the aedeagus without a forceps-shaped process distally; in M. forcipata, the apex-rounded valva has a denticle on the ventral margin, the sacculus has two triangular processes apically, and the aedeagus has a forcepsshaped process distally.

Description. Adult (Fig. 16). Forewing length 5.0‾ 5.5 mm.

Head yellow mixed with black on frons; vertex black, with yellow scales laterally. Labial palpus with first segment black, second and third segments yellow; second segment with dense blackish-grey scales on outer surface, with a black ring at pre-apex; third segment 2/3 length of second segment, with black scales medially. Antenna with scape yellow; flagellum blackish grey, ringed with yellow on ventral surface.

Thorax blackish grey, with yellow scales laterobasally and distally; tegula black except yellow distally. Forewing narrow lanceolate; ground colour greyish black, with a yellow stripe from base arched to below costal margin, then extending obliquely outward to basal 2/5 of fold, edged with black scales; costal margin with inner yellow spot narrow, from basal 2/5 obliquely outward and crossing anterior margin of cell, outer yellow spot at distal 1/4, inverted triangular, with a rounded black dot in middle anteriorly; dorsal yellow spot large, extending upward to posterior margin of cell, mixed with black scales; fold with a black spot at basal 3/5, edged with yellow scales on outer side; cell with a black spot at basal 3/5, surrounded by yellow scales, with black spot at anterior and posterior angles respectively, separated by a yellow spot at outer margin; small yellow spots running from apex along termen to beyond tornus, interrupted by black scales; fringe blackish grey, with a yellow basal line along termen. Hindwing and fringe deep grey. Legs yellow; on ventral surface, foreleg black except tibia yellow apically, tarsus yellow at base of basal tarsomere and at apices of basal two tarsomeres, femora of mid- and hindlegs mixed with black scales, tibiae of mid- and hindlegs black except yellow apically, mid tarsus black except yellow at apices of basal two tarsomeres, hind tarsus with basal four tarsomeres black except yellow at apices.

Male genitalia (Fig. 38). Uncus clavate, hooked apically. Gnathos with lateral arm heavily sclerotized, curved inward distally, membranous anteriorly. Tegumen narrowed medially; lateral arm olive-shaped, connected by a triangular sclerite medially, sclerotized along outer and inner margins. Valva with basal half narrow, widened from middle to apex, densely setose; apex truncate, produced in triangle dorsoapically; ventral margin heavily sclerotized, concave medially; costa narrow, reaching distal 2/3 of valva; transtilla short, connected by membrane medially. Sacculus with basal 2/3 parallel, distal 1/3 narrowed triangularly, heavily sclerotized, sparsely setose, with a papillary process at apex. Saccus slightly shorter than uncus, inverted triangular, wide at base, narrowed to rounded apex, shorter than valva. Juxta arched. Aedeagus slightly longer than valva, distal 2/3 mostly membranous, with a long curved belt, with several narrow sclerites distally; cornuti represented by two large spines.

Female unknown.

Distribution. China (Guangxi, Guizhou, Hainan).

Etymology. The specific epithet is derived from Latin word papilli- and setosus, referring to the setose papillary apical process of the sacculus.
