( Figures 25 , 40–44 )

Description

Length „ 4.0–4.2 mm.

Vertex and pronotum olivaceous yellow; face and sternum, scutellum and abdomen brown; ocelli reddish; frons with central area yellowish brown; fore wings brown with ochraceous granules.

Fore wings densely granulate; veins indistinct.

Male genitalia with subgenital plates ( Figures 40–42 ) with expanded basal region broad in ventral view, apical spine-like process short and stout, directed anterodorsally. Lateral plates ( Figure 41 ) with apical margin broad in lateral view, moderately protruding beyond pygofer. Styles ( Figure 43 ) with a dorsal subapical process and a ridge extending ventrally from near base of process. Aedeagus as in Figure 44 .

Female: unknown.

Distribution

Vietnam.

Material examined

Holotype: „, Vietnam: Tam Dao , 950 m, 15–30 September 1989 ( V. Novotny) ( IZCAS). Paratype: Vietnam: 1 „, same data as holotype ( BMNH).

Remarks

This species can be distinguished by its contrasting colour pattern and its basally broad subgenital plates with short apical process. It differs from the very similar B. uchidai from Taiwan, by its smaller size and narrower subgenital plates basally and shorter aedeagal shaft with more weakly arched basal part.
