description: Stathmopoda guangxiensis sp. nov.
(Figs 9, 22, 34)
Type material. CHINA, Guangxi: Holotype ♂, Mt. Dayao (24.15°N, 110.21°E), Jinxiu, 1364 m, 19.VII.2015, leg. MJ Qi & SN Zhao, slide No. GW15157. Paratypes: 1♀, other same data as holotype, slide No. GW 15156; Guangdong: 1♀, Mt. Babao, Nanling, 1070 m, 23.VIII.2010, leg. SL Hao.
Diagnosis. The new species is similar to S. neohexatyla Li et Wang, 2002 in the forewing pattern. It can be distinguished by the ochreous yellow forewing with blackish brown markings; in the male genitalia by the cucullus convex before middle on the dorsal margin, obtuse on the ventral margin, and the cornutus consisting of five denticles; in the female genitalia by the corpus bursae with a C-shaped signum. In S. neohexatyla, the pale yellow forewing has brown markings; the cucullus is smoothly obtuse on the dorsal margin, straight on the ventral margin, and the cornutus consisting of seven spines in the male genitalia; and the corpus bursae has a large crescent-shaped signum in the female genitalia (Li & Wang 2002, P. 332, Figs 3–4).
Description. Adult (Fig. 9). Wingspan 16.0–18.0 mm. Head with frons silvery white, vertex pale yellowish brown, occiput yellowish brown mixed with blackish brown. Labial palpus white on inner side, second segment blackish brown in basal 1/4, ochreous yellow in distal 3/4 on outer side, third segment ochreous yellow on outer side. Antenna ochreous yellow; scape silvery white on anterior margin, yellowish brown on posterior margin. Collar yellowish brown; thorax and tegula yellow, with blackish brown scales basally and apically. Forewing ochreous yellow; costal margin with a blackish brown streak, widened to fold basally, narrowed to basal 1/3, then slenderly extending to distal 1/4; broad blackish brown spot extending from basal 2/5 of cell obliquely inward to basal 1/4 of ventral margin, with a slender blackish brown streak from its outer margin along fold to distal 3/4 of fold; elliptical blackish brown spot from outer margin of cell extending to ventral margin, ochreous brown streak from outer side of this spot extending to distal 4/5, longitudinal blackish brown streak along middle of cell linked preceding two spots, forming a large inverted U-shaped speckle; ventral margin with a large triangular blackish brown spot at base, widened to fold and joined with costal streak anteriorly; fringe brown. Hindwing and fringe greyish brown. Legs yellowish white; foreleg with femur blackish brown on outer side, tibia blackish brown in basal half, with two fine blackish brown lines in distal half on outer side, tarsus blackish brown at apices of first and fifth tarsomeres; mid tibia with long pale yellowish brown hairs at middle and apex on dorsal surface, tarsus blackish brown at apex; hindleg ochreous yellow on dorsal surface, greyish brown on ventral surface, tibia with ochreous yellow bristles in basal 3/4 on dorsal surface, with long ochreous brown bristles at apex, tarsus annulated with blackish brown at apex of each tarsomere, with ochreous brown bristles at apices of basal three tarsomeres. Abdomen brown on dorsal surface, yellowish white on ventral surface.
Male genitalia (Fig. 22). Uncus wide at base, narrowed from base to apex, with long setae laterally; apex approximately 1/3 width of base. Gnathos elongate triangular, narrowed toward apex. Tegumen bifurcate from anterior half; lateral arm slightly narrowed anteriorly, with a papillary process at basal 2/5 on inner margin respectively. Valva narrow basally, subparallel to cucullus; cucullus sub-oval, length approximately 1.5 times of maximum width, roundly convex before middle dorsally, obtuse ventrally, rounded at apex; inner process short and strong; costa sub-rectangular; sacculus uniformly wide, approximately 2/5 length of valva, reaching base of cucullus, apex not free from cucullus. Vinculum narrowly banded. Juxta with posterior margin shallowly concave medially, anterior margin narrowly rounded; anellar lobes conical, approximately 1.5 times length of juxta, with short setae. Aedeagus tapered to apex, approximately 3/4 length of valva, with a sclerotized plate near base; cornutus consisting of five large denticles joined at base, located at middle.
Female genitalia (Fig. 34). Intersegmental membrane between papillae anales and eighth abdominal segment approximately 3.5 times length of papillae anales.Apophyses posteriores approximately 1.5 times length of apophyses anteriores. Eighth segment straight on posterior margin, with long setae; eighth tergite sub-rectangular; eighth stenite with anterior margin produced triangularly. Antrum sub-rectangular, strongly sclerotized anteriorly, slightly produced anteromedially, slightly concave on posterior margin. Ductus bursae approximately same length as corpus bursae, basal 3/5 almost uniform, distal 2/5 gradually widened. Corpus bursae oval; signum C-shaped, open posteriorly, serrate on posterior margin, located near entrance of corpus bursae (Fig. 34a); 28 denticles sparsely grouped at transition between ductus bursae and corpus bursae. Ductus seminalis arising from region of transition between ductus bursae and corpus bursae, broadly tubular, approximately twice length of corpus bursae, roundly inflated and curved at basal 1/3, then extending upward, with dense granules distally.
Distribution. China (Guangdong, Guangxi).
Etymology. The specific epithet is from the type locality, Guangxi.
