Type material.
Holotype: ♂, China: Guizhou, Jiangkou County, Fanjingshan National Nature Reserve (27°54'N, 108°38'E, 500-1800 m), 1-3 June 2002, X-S Chen leg.; paratypes: 10♂♂ 10♀♀, same data as holotype.
Diagnosis.
This species is similar to S. brunetus , but it differs from the latter by anal tube with spoon-like protrusion in lateral view ( Fig. 36 View Figures 32–41 ) (without spoon-like protrusion in S. brunetus ); dorsal lobe of phallobase with rod-like cystiform processes at apical part ( Fig. 40 View Figures 32–41 ) (without rod-like process in S. brunetus ); aedeagus with short hooked process, tip of process directed to dorso-posterior ( Fig. 40 View Figures 32–41 ) (tip of process directed to dorso-anterior in S. brunetus ).
Description.
Body length: male 3.61-3.98 mm, female 4.12-4.52 mm. Forewing: male 2.97-3.39 mm, female 3.46-3.80 mm.
Coloration. General color pale yellow to yellowish brown ( Figs 5 View Figures 1–8 , 6 View Figures 1–8 ). Vertex, pronotum and mesonotum ( Fig. 32 View Figures 32–41 ) pale yellow. Eyes brown to black ( Fig. 33 View Figures 32–41 ). Forewings ( Fig. 5 View Figures 1–8 ) pale yellow or yellowish brown, longitudinal veins pale brown, transverse veins pale white. Legs yellow brown, with tips of spines on hind tibiae and tarsi black.
Head and thorax. Head ( Fig. 32 View Figures 32–41 ) including eyes slightly narrower than pronotum (0.75: 1.00). Vertex ( Fig. 32 View Figures 32–41 ) shorter in middle than the wide at base (1.00: 3.00). Frons ( Fig. 34 View Figures 32–41 ) longer in middle than the widest breath (1.09: 1.00), median carina with the apical margin obscurely forked, nearly reaching to frontoclypeal suture. Clypeus triangular, with distinct median carina ( Fig. 34 View Figures 32–41 ). Pronotum ( Fig. 32 View Figures 32–41 ) with median carina obscure, lateral carina reaching to the posterior margin. Mesonotum ( Fig. 32 View Figures 32–41 ) triangular, without median carina. Forewings ( Fig. 35 View Figures 32–41 ) elongate, 1.82 times as long as maximum breadth. Hindwings absolutely reduced. Hind tibiae each with two lateral spines, spinal formula of hind leg 7 –9– 2.
Male genitalia. Anal tube ( Fig. 37 View Figures 32–41 ) irregularly ligulate in dorsal view, the widest in apical 1/3, longer in midline than the width (1.85: 1.00), in lateral view anal tube with spoon-like protrusion ( Fig. 36 View Figures 32–41 ). Anal style ( Fig. 37 View Figures 32–41 ) sturdy and long, located at the base third of anal tube. Pygofer ( Fig. 36 View Figures 32–41 ) with dorsal margin slightly narrow than ventral margin. Genital styles ( Fig. 38 View Figures 32–41 ) relatively rectangular, dorsal margin slightly arched. Capitulum of genital styles relative long, irregularly triangular, neck obvious ( Fig. 39 View Figures 32–41 ). Phallobase ( Figs 40 View Figures 32–41 , 41 View Figures 32–41 ) with dorsal lobe finger-like cystiform process near apical part ( Fig. 40 View Figures 32–41 : a), with relatively curved rod-like process in apical 1/3 ( Fig. 40 View Figures 32–41 : b) in lateral view; lateral lobe splitting into two stout branches, the apical margin truncated in ventral view; ventral lobe short, unobvious lobe-like process near middle, reaching to 3/4 of dorsal lobe in lateral view, with three unobvious small lobes in ventral view. Aedeagus with short hooked process in the middle in lateral view, directed to dorso-posterior ( Figs 40 View Figures 32–41 : c, 41: c).
Female genitalia ( Figs 42-50 View Figures 42–50 ). Anal tube ( Fig. 45 View Figures 42–50 ) nearly oval, longer in middle than the widest breadth (1.70: 1.00), the apical margin arched, with unobvious membranous triangular protuberance, the widest at the basal 1/2. Anal style long, located at the basal fifth of anal tube ( Fig. 45 View Figures 42–50 ). Anterior connective lamina of gonapophysis VIII with obviously sclerous triangular process in basal dorsal margin, with three lateral teeth bearing three keels in lateral group and three apical teeth ( Fig. 46 View Figures 42–50 ). Posterior connective lamina of gonapophysis IX ( Figs 47 View Figures 42–50 , 48 View Figures 42–50 ) relatively broad, median field symmetrical, with nearly circular prominences, apical margin deeply incised in middle (medial dorsal process) ( Fig. 47 View Figures 42–50 ); ventroposterior lobes bent at obtuse angle (posterior ventral lobes), with membranous triangular process at inner region near the apical part ( Fig. 48 View Figures 42–50 ). Gonoplacs ( Fig. 49 View Figures 42–50 ) without keels. Hind margin of sternum VII median distinctly concave in ventral view ( Fig. 50 View Figures 42–50 ).
Etymology.
This new species is derived from the Latin word hamulatus , referring to the short hamular process of aedeagus.
Host plant.
Unknown.
Distribution.
China (Guizhou).
Remarks.
This new species is distinguished from other species of this genus by: 1) anal tube irregularly ligulate in dorsal view, with spoon-like protrusion in lateral view ( Fig. 37 View Figures 32–41 ); 2) phallobase with dorsal lobe rod-like cystiform processes at apical part, ventral lobes with three not obvious small lobes in ventral view ( Fig. 40 View Figures 32–41 ); 3) aedeagus with short hooked process in middle in lateral view ( Fig. 40 View Figures 32–41 ); 4) female genitalia with posterior connective lamina of gonapophysis IX in median field with nearly circular process ( Fig. 47 View Figures 42–50 ).
