Figures 4 , 12 , 19 , 22 , 26, 29, 30 , 41a–b

Habitus Fig. 4 . Colour light brown, antennae and legs dusky yellow. Antennomeres 3–11 Fig. 22 . Distance across eyes 0.19 mm. Labrum with a scalloped anterior margin, Fig. 30 . Mentum widest at anterior margin and sides without a median swelling, Fig. 26 . Pronotum 0.26 mm wide, 0.19 mm long, Fig. 19 . Elytra 0.40 mm long, 0.35 mm wide. Mesoventrum with two deep fossae close to the collar on the anterior margin, Fig. 12 . Lateral points on the metaventral margin between the metacoxae of medium length, triangular. Abdominal ventrites VI and VII with a series of prominent setae, and ventrite VIII with deep incision, Fig. 29 . Females unknown.

Etymology. Patronymic, after Dr Petr Baňař, the collector

Diagnosis. The deep fossae in the mesoventrum coupled with the abdominal characteristics of the male will distinguish this species.
