Description.

Measurements. Body length (including forewing): male 6.76 mm (1 specimen); female 6.80 (1 specimen); forewing length: male 5.60 mm (1 specimen); female 5.72 (1 specimen).

Coloration. Generally yellowish brown ( Figs 1-3 View Figures 1–6 ). Crown and pronotum yellowish brown to brown ( Figs 4 View Figures 1–6 , 5 View Figures 1–6 ). Face dark brown ( Fig. 6 View Figures 1–6 ). Legs with dark spots ( Fig. 3 View Figures 1–6 ). Forewing with yellow veins ( Figs 1-3 View Figures 1–6 ).

Head and thorax. Head including eyes as long as width of pronotum. Crown with fore margin arc-shaped, median length shorter than width between eyes (0.4:1) ( Figs 1 View Figures 1–6 , 4 View Figures 1–6 ). Coronal suture visible at basal one-third to one-half of crown ( Figs 1 View Figures 1–6 , 4 View Figures 1–6 ). Ocelli about 1/3 distant from eye to crown apex ( Figs 1-4 View Figures 1–6 ). Face with frontoclypeus longer than wide; anteclypeus slightly expanded apically; lorum broad ( Fig. 6 View Figures 1–6 ); antennae arising near lower corner of eye ( Fig. 6 View Figures 1–6 ). Scutellum slightly shorter than pronotum (0.8:1) ( Fig. 4 View Figures 1–6 ). Forewing elongate, with four apical cells; appendix wide ( Figs 1-3 View Figures 1–6 ).

Male genitalia. Pygofer elongate in profile, ventral margin with two elongate acute processes at distal one-third and subapically ( Figs 7 View Figures 7–15 , 8 View Figures 7–15 ), with a few fine teeth-like processes along ventroposterior margin ( Fig. 8 View Figures 7–15 ). Valve triangular, basal width slightly longer than median length (1.42:1) ( Fig. 15 View Figures 7–15 ). Subgenital plate elongate, triangular; with uniseriate row of ventral macrosetae along lateral margin; apical margin rounded with very short fine setae ( Fig. 15 View Figures 7–15 ). Connective Y-shape, shaft robust, similar length to arms ( Fig. 13 View Figures 7–15 ). Styles ( Figs 10 View Figures 7–15 , 13 View Figures 7–15 ) elongate, with apophysis relatively long and stout with small subapical tooth-like process from inner margin ( Figs 12 View Figures 7–15 , 13 View Figures 7–15 ). Aedeagus with basal apodeme absent; shaft elongate, cylindrical, tapering to acute apex, with two pairs of small triangle processes near apex ( Figs 9-11 View Figures 7–15 ); with subbasal elongate medial process from ventral margin, directed dorsally; with short preatrium.

Female genitalia. Sternite VII ( Fig. 16 View Figures 16–20 ) with anterior margin nearly straight and posterior margin strongly convex with blunt median tooth. First valvula ( Figs 17 View Figures 16–20 , 18 View Figures 16–20 ) curved, tapering apically with strigate sculpture extended to dorsal margin. Second valvula ( Figs 19 View Figures 16–20 , 20 View Figures 16–20 ) broad, gradually tapered to acute apex; dorsal margin with numerous small triangular teeth; with dorsal sclerotized and hyaline region.

Type material.

Holotype: ♂, China: Yunnan Province, Maguan County, 23. XI. 2016, Ya-Lin Yao. Paratype: 1♀, same as holotype.

Host plants

. Bamboo.

Distribution.

Southwest China (Yunnan Province).

Remarks.

This new species is similar to B. bambusae , but can be distinguished from the latter by: aedeagus with a long medial process subbasally from ventral margin, directed dorsally ( Figs 10 View Figures 7–15 , 11 View Figures 7–15 ) (aedeagus with a tooth-like ventro-basal process, directed ventrally in bambusae ); shaft long and tapered to apex, with two pairs of small triangle processes near apex ( Figs 9-11 View Figures 7–15 ) (shaft without process subapically in bambusae ).

Etymology.

The name is derived from the Latin words “longus” and “spina”, referring to the aedeagus with a long spinous process near base ( Fig. 11 View Figures 7–15 ).
