Neotaxilanoides orientalis sp. n.

( Figs 1–13 )

Description. Body length: Male. 6.5–7.0 mm (n=14), female 6.6–7.2 mm (n=3).

Color. General color green to pale green. Eyes black. Vertex, pronotum, mesonotum and abdomen green. Forewings pale green with veins dark green. Genital segment pale green. Legs pale green with apices of spines on tibiae and tarsi black. Dry preserved specimen ochraceous ( Figs 1, 2 ).

Head. Head including eyes narrower than pronotum (1.0: 1.4) ( Figs 1 , 3 ). Vertex 1.3 times longer in midline than wide at base, posterior margin nearly straight, disc of vertex slightly depressed with one median carina ( Figs 1 , 3 ). Frons slightly depressed, longer in middle than maximum breadth (1.7: 1.0), lateral margins sinuate, produced laterally at the upper level of eyes and concave inwardly in apical half ( Figs 4, 5 ). Postclypeus with median carina ridged, anteclypeus not ridged in midline ( Figs 4, 5 ). Eyes oval ( Figs 2 , 5 ). Ocelli small, very close to eyes. Antennae short, scape cylindrical, pedicel cylindrical, slightly expanded at apex, apically covered with microsetae and wrinkled sensory plaques.

Thorax. Pronotum wider than long medially (4.7: 1.0), anterior margin straight, posterior margin obtusely excavated and not ridged; disc about as broad as vertex at base, lateral carinae not converging anteriorly, extending to hind margin, median carina distinctly ridged ( Figs 1 , 3 ), with one short lateral carina on either side between eye and tegula ( Figs 2 , 5 ). Mesonotum as wide as long in middle line, tricarinate, median carina straight, reaching to transverse suture separating dorsal angle, lateral carinae sinuate, extending to hind margin; pronotum and mesonotum together 2.0 times as long as vertex in midline ( Figs 1 , 3 ). Forewings semitransparent, far beyond tip of abdomen, rounded apically, widest at apical fourth, about 2.7 times longer than maximum breadth; corium with granulation; Sc+R forked at apical 2/5, Cu1 forked at basal 1/4, M simple, nodal line even and oblique, uniting point of claval veins distad of middle of clavus, with at least 10 short longitudinal veins in membrane, several ranks transverse veins densely interspersed and grid-shaped in apical cellar area ( Figs 1 , 6 ). Hindwings transparent. Hind tibia with 2 lateral and 5 apical spines, metabasitarsus with 5 spines apically.

Male genitalia. Pygofer quadrangular, latero-caudal margin declined postero-ventrally ( Fig. 8 ). Anal segment elongate, relatively thin in profile, anal styles long, beyond end of anal tube ( Figs 8, 11, 12 ). Genital styles symmetrical, in lateral view apical 2/5 bent caudo-dorsad, in ventral aspect broad at base, narrowing apically; fused in basal 2/3 and near base with an angular process in middle; with a finger-like process directed latero-basad on each side; apical third produced in a rounded process along inner margin, symmetrical and contiguous ( Figs 9, 10 ). Aedeagus distinctly surpassing apex of genital styles in lateral view, tubular, slightly sinuate, apex splitting to periandrium on left side ventrally, with two long narrow processes arising from dorsal side subapically ( Figs 8, 11–13 ).

Periandrium well developed, not symmetrical bilaterally, connected with ventral base of anal segment, surrounding aedeagal shaft in middle; subapex expanded and produced laterally in left view ( Figs 8, 11–13 ).

Material examined. Holotype male, China: Hainan Province, Jianfengling, 980 m, 8 May 2008, coll. Qiulei Men. Paratypes.
