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). Crown and pronotum yellowish brown to brown (Figs 4, 5). Face dark brown (Fig. 6). Legs with dark spots (Fig. 3). Forewing with yellow veins (Figs 1–3).
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, 4). Coronal suture visible at basal one-third to one-half of crown (Figs 1, 4). Ocelli about 1/3 distant from eye to crown apex (Figs 1–4). Face with frontoclypeus longer than wide; anteclypeus slightly expanded apically; lorum broad (Fig. 6); antennae arising near lower corner of eye (Fig. 6). Scutellum slightly shorter than pronotum (0.8:1) (Fig. 4). Forewing elongate, with four apical cells; appendix wide (Figs 1–3).
Male genitalia. Pygofer elongate in profile, ventral margin with two elongate acute processes at distal one-third and subapically (Figs 7, 8), with a few fine teeth-like processes along ventroposterior margin (Fig. 8). Valve triangular, basal width slightly longer than median length (1.42:1) (Fig. 15). Subgenital plate elongate, triangular; with uniseriate row of ventral macrosetae along lateral margin; apical margin rounded with very short fine setae (Fig. 15). Connective Y-shape, shaft robust, similar length to arms (Fig. 13). Styles (Figs 10, 13) elongate, with apophysis relatively long and stout with small subapical tooth-like process from inner margin (Figs 12, 13). Aedeagus with basal apodeme absent; shaft elongate, cylindrical, tapering to acute apex, with two pairs of small triangle processes near apex (Figs 9–11); with subbasal elongate medial process from ventral margin, directed dorsally; with short preatrium.
Female genitalia. Sternite VII (Fig. 16) with anterior margin nearly straight and posterior margin strongly convex with blunt median tooth. First valvula (Figs 17, 18) curved, tapering apically with strigate sculpture extended to dorsal margin. Second valvula (Figs 19, 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, 11) (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) (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).
