Stathmopoda jinxiuensis S. Wang & Guan , sp. nov.

( Figs 12 , 37 )

Type material. CHINA, Guangxi: Holotype ♂, Mt. Dayao (24.14°N, 110.09°E), Jinxiu, 823 m, 20.VII.2015, leg. MJ Qi & SN Zhao, slide No. GW 15055.

Diagnosis. The new species is similar to S. miniloba sp. nov. in the features of the male genitalia, but it can be distinguished by the dark brown forewing having a large yellow subbasal patch; the costa of the valva produced trapezoidally, the triangular cucullus, and the aedeagus with cornuti. In S. miniloba , the brown forewing has a large silvery white subbasal patch; the costa of the valva is produced triangularly, the cucullus is sub-ovate, and the aedeagus lacks cornutus in the male genitalia.

Description. Adult ( Fig. 12 ). Wingspan 11.0 mm. Head with frons white; vertex brown; occiput rust red. Labial palpus silvery white on inner surface, second segment yellowish brown on outer surface, third segment dark brown on outer surface. Antenna dark yellowish brown, with scattered blackish brown scales on scape. Thorax ochreous yellow except black from middle to before posterior margin, with two silvery white dots at posterior 1/3; tegula ochreous yellow, with scattered grey scales. Forewing dark brown, with two ochreous yellow spots between costal margin and fold basally, with an ochreous yellow streak along basal 1/4 of fold; large triangular yellow patch extending from basal 1/5 of costal margin widened to between basal 1/8 and 3/10 of dorsal margin; fringe dark brown. Hindwing and fringe dark brown. Legs pale brown dorsally, cream ventrally; foreleg with tibia and tarsus blackish brown on outer surface; midleg with tibia blackish brown at base, middle and apex, with ochreous yellow bristles at middle and apex; hindleg with tibia bearing long brown bristles at apex, tarsus with brown bristles at apex of basal tarsomere. Abdomen blackish brown on dorsal surface, greyish white on ventral surface.

Male genitalia ( Fig. 37 ). Uncus wide at base, gradually narrowed to middle, abruptly narrowed from beyond middle to narrowly rounded apex. Gnathos lingulate, produced medioapically. Tegumen with height 1.2 times length of uncus, extended anterolaterally. Valva with costa produced trapezoidally; cucullus triangular, obliquely upturned, apex obtusely rounded, produced dorsoapically, rounded at ventroapical corner; sacculus 3/5 length of valva, narrowly banded, slightly concave near base on ventral margin, apex pointed, reaching ventroapical corner of cucullus. Vinculum band-shaped, triangularly extended, rounded anteriorly. Juxta inverted triangular, broadly obtuse on posterior maigin; narrowed anteriorly; anellar lobes oval, half length of juxta, with short setae. Aedeagus 1.3 times length of valva, tapered from base to apex, with a sclerite near base, with numerous spicules near apex; distal process 1/3 length of aedeagus, curved, rounded at apex; cornuti consisting of a tuft of long spines and a tuft of short spines, located at middle and near apex respectively.

Female unknown.

Distribution. China (Guangxi).

Etymology. The specific epithet is from the type locality, Jinxiu.
