Holotype: ♂, China: Hainan, Bawangling (22°28'N, 106°57'E), 13 March 2014, S-Y Xu and J-K Long leg.; paratypes: 10♂♂ 3♀♀, Hainan, Bawangling (22°28'N, 106°57'E), 30 April 2017, L-J Yang leg.; 4♀♀, Hainan, Diaoluoshan (18°39'N, 109°55'E), 15 April 2017, L-J Yang leg.

Diagnosis.

This new species is distinguished by the following characters: vertex with four black brown bands along lateral margins and median carina (Fig. 7 ); mesonotum with each other one dark spot between lateral and sublateral carinae (Fig. 7 ); genital styles with irregular triangular prominence near dorsal margin at base of capitulum (Fig. 12a ); dorsal lobe of phallobase with one small claviform process in base (Fig. 15b ), and convex protrusion near middle (Fig. 15c ) and apical part with a duckbill-like process (Fig. 15d ), lateral margin with one long hooked process (Fig. 15e ) on each side; ventral lobe with apical part mushroom-like in ventral view (Fig. 16h ); aedeagus with one short hooked process near apical 1/3 in lateral view, directing to cephalad (Fig. 15i ).

Description.

Body length (from apex of vertex to tip of forewings): male 7.80-8.31 mm (N = 11), female 8.80-9.30 mm (N = 7); forewing: male 6.50-7.80 mm (N = 11), female 7.60-9.30 mm (N = 7).

Coloration. General colour yellow-green (Fig. 5 ). Vertex (Fig. 7 ) yellow-brown, with four black brown bands along lateral margins and median carina, with pale yellow median carina. Frons and clypeus (Fig. 9 ) ochreous. Compound eyes black brown, ocelli pale ochreous (Fig. 8 ). Pronotum and mesonotum (Fig. 7 ) yellow brown, mesonotum with pair of dark spots between lateral carinae and sublateral carinae. Male forewings (Fig. 6 ) yellow green, with diffusely brownish irregular speckles near middle of MP vein and CuA vein, and the base of ScP+RP vein; female forewings brown. Hindwings transparent. Abdomen pale yellow-green, suffused with black-brown near middle line. Male genitalia pale yellow green. Female genitalia brown black. Tip of spines on hind tibiae and tarsi black.

Head and thorax. Head (Fig. 7 ) including eyes distinctly narrower than pronotum (0.77: 1.00). Vertex (Fig. 7 ) slightly shorter in middle than the width (0.75: 1.00). Frons (Fig. 9 ) longer in middle than the maximum width (1.14: 1.00), with median carina nearly reaching frontoclypeal suture, sublateral carinae obscure, nearly reaching the level of middle of frons. Pronotum (Fig. 7 ) shorter in midline than the width (0.31: 1.00). Mesonotum (Fig. 7 ) shorter in midline than its width (0.43: 1.00); the basal part forked, scutellum sunken. Forewings (Fig. 10 ) longer than width (2.33: 1.00), MP two branches near basal 1/3, MP1 dividing two branches in distal 1/4, MP2 not forked, CuA forked into two branches in middle of forewing, Pcu and A1 uniting slightly after MP bifurcation. Hindwings (Fig. 11 ) with one transverse vein between CuP and Pcu near apical part, with transverse vein between Pcu+A11 and A12 near basal 1/3. Spinal formula of hind leg (2)7/6, 7/2.

Male genitalia. Anal tube (Fig. 13 ) longer than its widest breath (2.90: 1.00) in dorsal view, anterior margin arched convex, lateral margins nearly parallel at apical 2/3, the basal 1/3 part broader than apical part. Anal style (Fig. 13 ) small, extremely short and thin, located in basal 2/5 of anal tube, not surpassing the end of the anal pore. Pygofer (Fig. 12 ) with dorsal and ventral margin paralleled in lateral view. Genital styles (Fig. 12 ) with irregular triangular prominence at base of capitulum (Fig. 12a ). Capitulum of genital styles irregularly keen-edged triangular, neck very long and obvious (Fig. 14 ). Phallobase (Figs 15 , 16 ) with dorsal margin of dorsal lobe with one small claviform process in base (Fig. 15b ) in lateral view, convex protrusion near middle (Fig. 15c ) and apical part with duckbill-like process (Fig. 15d ), lateral margin with one long hooked process on each side (Figs 15e , 16e ), surpassing middle of phallobase, directing to cephalad, and lateral margin waved obviously, with one lobe-like process (Fig. 15f ); lateral lobe splitting into two branches, slightly shorter than the dorsal lobe, with unobvious small lamina-like process (Fig. 15g ); ventral lobe slightly shorter than lateral lobe in lateral view, stout, with apical part mushroom-like (Fig. 16h ) in ventral view. Aedeagus (Figs 15 , 16 ) with one short hooked process on each side (Figs 15i , 16i ) near apical 1/3 in lateral view, directing to cephalad.

Female genitalia. Anal tube (Figs 17 , 20 ) longer in middle line than the width (3.15: 1.00), the basal 1/3 part broader, inclined to ventral margin in lateral view (Fig. 21 ). Anal style (Figs 20 , 21 ) long and stout, located in basal 1/6 of anal tube, surpassing the end of anal pore. Anterior connective lamina of gonapophyses VIII (Figs 18 , 22 ) extremely long saw-like, with a row of teeth in inner lateral margin (Fig. 22 : tl). Posterior connective lamina of gonapophyses IX (Figs 23 , 24 ) relatively broad in dorsal view, with lateral field and sublateral field unobvious, membranous, median field membranous, with deep sunken (Fig. 23 : mf), apical part of ventroposterior lobes with long flagelliform process (Fig. 23 : fp). Gonoplacs (Fig. 25 ) irregularly triangular, tapering, apical part membranous, thin tuber in latera view; fused dorsally to form a sheath surrounding the anterior connective lamina of gonapophyses VIII (Fig. 26 ). Hind margin of sternite VII with distinctly triangular prominence in middle area in ventral view (Fig. 19 ), inner margin with membranous process (Fig. 27 ).

Distribution.

China (Hainan).

Etymology.

The species name is derived from a combination of the prefix “bi-” and Latin noun “punctata”, suggesting the paired dark spots of mesonotum.

Host plant.

Unknown.
