Idioceroides sichuanensis View in CoL n. sp.
( Figs 1 View FIGURE 1 , 2 View FIGURE 2 )
Description: Length: male 5.6–6.2 mm, female 6.3 mm.
Male. Lemon yellow with large black patches. Vertex with round spot on either side of median line closer to eyes, one triangular spot on posterior margin medially ( Fig. 1A View FIGURE 1 ), most of face except dorsal triangular patch, black ( Fig. 1C View FIGURE 1 ). Pronotum black, except anterior transverse broken arcuate band, caudal and lateral lemon yellow areas. Scutellum lemon yellow, with median stripe and basal triangles black. Forewing with venation, coastal band and inner claval cell dark brown, spot at base of clavus, one oblique band across clavus and corium at midlength whitish ( Fig. 1D View FIGURE 1 ).
Face rather tumid in lower half, clypellus very broad in basal 0.66 and then abruptly narrowed, clypoclypellar suture complete.
Male genitalia ( Figs 1E, F, G, H, I View FIGURE 1 ). Anal collar process well developed, spatulate, with caudal apex rounded. Pygofer in lateral view with dorsal margin straight, ventral margin convex with small triangular projection in basal 0.25. Valve broader than long, caudal margin rounded. Subgenital plate in lateral view narrow, elongate, without long setae, apically rather pointed. Style with anterior part before articulation with connective short, caudal part about 6 times as long as anterior part, distally strongly curved dorsally. Aedeagus in lateral view with basal part thinner and shorter than shaft, arcuate; aedeagal shaft cylindrical, strongly curved dorsally, with one pair of subapical processes laterally.
Female. Lemon yellow with large rufous areas ( Fig. 2A View FIGURE 2 ). Vertex with one median stripe and large spot on either side of median line continued on face rufous. Face rufous except yellow median spot between eyes and lateral margins of genae ( Fig. 2C View FIGURE 2 ). Pronotum rufous with anterior submarginal series of four spots and one median stripe, lateral and caudal margins, lemon yellow. Scutellum similarly colored as in male but black areas replaced by rufous. Forewings rufous, apices of outer claval veins, claval suture, lemon yellow.
Face not tumid in lower side as compared to male, clypellus broader at base than at apex, lateral margins concave; clypo-clypellar suture incomplete in middle. Female pregenital sternite wider than long, hind margin medially excavated, laterally insinuated ( Fig. 2E View FIGURE 2 ). Second pair of valvulae strongly arched near base, dorsoapical half with approximately 24 teeth ( Figs 2G, H View FIGURE 2 ).
Material examined. Holotype: male, China, Sichuan, Yajiang , 8 August 2005, Fuming, Shi . Paratypes: one male and one female, same data as holotype .
Host plant. Unidentified shrubs.
Diagnosis: The new species resembles Idioceroides tettigoniformis externally, but differs in the male in having two distinct black round spots on the vertex between eyes, scutellum with basal triangles black and a black longitudinal stripe medially and the aedeagal shaft rounded apically, with two pairs of subapical processes. The female I. sichuanensis differs from female I. tettigoniformis ( Fig.3 View FIGURE 3 ) in having more strongly arched pronotal disc, face with more extensive dark brown coloration in addition to the differences mentioned in the key to species.
Etymology. The specific name refers to the type locality, Sichuan, China.
