Bundera bambusana sp. nov.

( Figs 11–20 )

Measurements. Body length including forewing: male 6.35–6.75 mm (n=14), female 6.85–7.10 mm (n=9).

Coloration. Male ( Figs 11, 12, 14, 15 ) black. Crown pale yellowish brown, with a tower-like blackish brown marking medially. Face blackish brown except ventral margins of genae pale yellowish brown. Anntenae, ocelli and eyes yellowish brown. Forewings blackish brown, claval area with pale yellowish brown triangular marking at base, outer side of apex of claval area and costal margin near apical one third with one small and one large hyaline marking, respectively. Legs with apical claw, apex of hind tibia and distal portions of tarsi dark brown. Abdomen blackish brown. Female ( Fig. 13 ) pale yellowish brown. Crown with four blackish brown transverse markings. Face with lateral margins and median longitudinal carina dark brown. Pronotum with several brown patches. Forewing yellowish brown except apex of claval area blackish brown.

Head and thorax. Head ( Fig. 12 ) with vertex angularly produced, median length shorter than width between eyes (0.73: 1); lateral margin carinate; submarginal carina mesad of ocelli on head; area between median carina and submarginal carina slightly concave. Face including eyes ( Fig. 15 ) slightly longer than wide (1.12:1); frontoclypeus with strongly elevated median longitudinal carina, laterally obliquely striate; clypellus broad and swollen at base, narrowed apically, shagreened; lora not reaching apex of clypellus, flat; gena strongly declivous laterally. Pronotum ( Fig. 12 ) wider than head including eyes (1.17:1), slightly longer than vertex in middle line (1.27:1). Scutellum ( Fig. 12 ) triangular, shorter than pronotum (0.85:1), with transverse depression distinct. Forewing with four apical cells; appendix very narrow.

Male genitalia. Male pygofer ( Fig. 15 ) nearly broad triangular in lateral view, tapering apically, apex slightly curved upward, apical margin nearly truncate. Subgenital plate ( Fig. 17 ) elongate, apex rounded, with hair-like or macrosetae arranged in rows. Style ( Figs 18–20 ) slender, elongate, broad at middle, apophysis foot-like, heel tapering triangular, lateral angle elongate, tapering apically, apical margin nearly truncate. Connective ( Figs 18, 19 ) Y-shaped, with stem much longer than arms (4:1). Aedeagus ( Figs 19–20 ) curved dorsad in lateral view, with pair of well developed process on dorsal part of atrium, respectively; ventral margin angularly produced; aedeagal shaft with apical portion tubular, curved; gonopore apical.

Host plant. Bamboo.

Distribution. China (Yunnan).

Type materials. Holotype: 3, China: Yunnan, Lushui, Pianma (98°37´N, 26°01´E, 2800 m), bamboo, 17 Aug. 2000, X.-S. Chen; paratypes: 13 3, 9 ƤƤ, data same as holotype (IEGU).

Etymology. The new species is named after the host plant bamboo ( Bambusoideae ).

Remarks. This new species closely resembles Bundera maculata Kuoh, 1987 , but differs in the following characters: larger body size, body length including forewing 3 6.35–6.75 mm, Ƥ 6.85–7.10 mm (male 5.70mm, female 6.20 mm in maculata ); apex of pygofer tapering and curved upward (rounded in maculata ); ventral margin of aedeagus sharp (rounded in maculata ); style with inner angle of apex tapering triangular (rounded in maculata ).
