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

( Figs 20 , 45 , 65 )

Type material. CHINA, Hong Kong: Holotype ♂, Kadoorie Farm (22°26′N, 114°07′E), 210 m, 15.IV.2007, leg. HH Li, slide No. GW 13159 . Paratypes. 6♂ 4♀, 11–21.IV.2007, other same data as holotype, slide No. GW13160 ♀; 1♂, Kadoorie Agric. Reaearch Centre Shek Kong N.T., Hong Kong. Utm : 50Q KK 029833, 200 m, 11.VII.1997, 125W MV, leg. R. C. Kendrick ( KFBG) ; 1♂, Kadoorie Agric. Reaearch Centre Shek Kong N.T., Hong Kong. Utm : 50Q KK 029832, 200 m, 8.VII.1998, 125W MV, leg. R.C. Kendrick ( KFBG) ; 1♂, Dagangzai , Xigong, 150 m, 15.IV.2007, leg. HH Li, slide No. WAL19145 ; 1♀, Weihai Village , 60 m, 27.IX.2009, leg. HH Li, slide No. WAL19146 .

Diagnosis. The new species is similar to S. diplaspis ( Meyrick, 1887) superficially. It can be distinguished in the male genitalia by the costa of the valva slightly projected before basal 1/3 and the aedeagus lacking spicules; in the female genitalia by the corpus bursae with one signum. In S. diplaspis , the costa is convex dorsally and the aedeagus has numerous spicules ranging from basal 1/4 to 3/4; the corpus bursae has two signa. The new species is also similar to S. callopis Meyrick, 1913 in the features of genitalia, but can be distinguished by the forewing having two cream white patches and an ochreous yellow apical spot, the valva uniformly wide to obtuse apex and the narrowly banded sacculus smooth dorsally, and the appendix bursae has about 25 denticles basally. In S. callopis , the forewing has two ochreous yellow fasciae but lacks an ochreous yellow apical spot, the valva is slightly narrower distally and the sacculus is projected at dorsal 3/5, and the appendix bursae with more than 60 denticles ( Wang 2006, P. 228, figs 385, 386). The new species is close to S. delitescens sp. nov. in the male genitalia, and the differences between them are stated in the diagnosis of the latter species.

Description. Adult ( Fig. 20 ). Wingspan 8.0‒12.0 mm. Head with frons and vertex white; occiput ochreous brown. Antenna with scape white; flagellum dark brown except white basally. Labial palpus yellowish white on inner surface, yellowish brown on outer surface, second segment dark brown in basal half on outer surface. Thorax and tegula dark brown. Forewing dark brown, with two sub-elliptical cream white patches, edged with ochreous yellow scales: antemedian patch from basal 1/4 of ventral margin slightly narrowed and oblique outward to below costal margin; postmedian patch from beyond middle to basal 3/4, reaching costal margin anteriorly; apical spot ochreous yellow, small; fringe brown. Hindwing and fringe pale brown. Legs yellowish brown dorsally, cream white ventrally; foreleg with tibia and tarsus blackish brown; midleg with tibia with yellowish brown bristles at middle and apex on dorsal surface, tarsus blackish brown at apex; hindleg with tibia blackish brown and bearing brown bristles at apex, tarsus blackish brown on dorsal surface, with short yellowish brown bristles at apices of basal two tarsomeres. Abdomen greyish brown on dorsal surface; greyish white on ventral surface.

Male genitalia ( Fig. 45 ). Uncus wide at base, gradually narrowed to apex, obtuse at apex, with long setae laterally. Gnathos lingulate, narrowed to bluntly rounded apex. Tegumen with height 1.8 times length of uncus. Valva sub-rectangular, uniformly wide to obtuse apex; inner process short, conical; costa concave obliquely inward basally, slightly projected before basal 1/3; sacculus narrowly banded, half length of valva, smooth dorsally, slightly concave at middle ventrally, pointed apically, not free from valva. Vinculum narrowly banded; saccus 1/5 length of uncus, papillary anteriorly. Juxta heart-shaped, concave in wide V-shape posteriorly, obtusely rounded anteriorly; anellar lobes elliptical, same length as juxta. Aedeagus tapered from base to apex, 1.4 times length of valva, with a sclerotized plate near base; distal process clubbed, 3/10 length of aedeagus; cornutus absent.

Female genitalia ( Fig. 65 ). Intersegmental membrane between papillae anales and eighth abdominal segment approximately three times length of papillae anales. Apophyses posteriores approximately twice length of apophyses anteriores. Eighth segment straight on posterior margin, with long setae; eighth tergite concave in V-shape anteriorly, eighth sternite produced anteriorly. Antrum funnel-shaped, weakly sclerotized. Ductus bursae almost uniform, approximately 1.5 times length of corpus bursae. Corpus bursae rounded, spiculate; signum filiform, placed anteriorly. Appendix bursae originating from transition of ductus bursae and corpus bursae, roundly dilated and with 25 small denticles basally; bulla dilated, located at about middle; ductus seminalis narrow, with dense granules distally.

Distribution. China ( Hong Kong).

Etymology. The specific epithet is derived from the Latin para - and the name of another species diplaspis , referring to the similarity of the two species.
