PX Cong et al. , slide No. YAH15439 ; 2♂, Yinggezui , Yinggeling , 599 m , 30.VII.2017 , leg. X Bai et al ( NKU ) . 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.
