Type locality. Vietnam, Vinh Phuc Province, Tam Dao.

Type material examined. HOLOTYPE: ♂, ‘ Vietnam, Prov.Vinh-phu ( divided into Vinh Phuc and Phu Tho), Tam-dao , L. Medvedev @ Dang Dap // on Ormosia (Fab.) // HOLOTYPUS Gonioctena ( Brachy.) medvedevi sp. n. Cho & Borowiec 2014’ ( LMCM). PARATYPES: 1 ♂ 1 ♀, same data as holotype plus ‘PARATYPUS Gonioctena ( Brachy.) medvedevi sp. n. Cho & Borowiec 2014’ ( LMCM); 1 ♂, same data as preceding paratype ( TLMF); 1 ♂, ‘ Vietnam, TamDao, 900 m, 4.VI.1987, L. Medvedev et al. // PARATYPUS Gonioctena ( Brachy.) medvedevi sp. n. Cho & Borowiec 2014’ ( LMCM).

Description. See CHO & BOROWIEC (2016a).

Differential diagnosis. Gonioctena ( B.) medvedevi is very similar to G. ( B.) longshengensis sp. nov. and G. ( B.) mauroi in body shape, coloration and setose aedeagus. From these two species, G. ( B.) medvedevi can be distinguished only by aedeagus moderately narrowed with apical process moderately widened to lateral tooth-like projections near apex (subparallelsided with apical process broad, widest in apical 1/3 and subequal to median lobe in width in G. ( B.) longshengensis sp. nov. and subparallel-sided with apical process widest in middle and slightly narrower than median lobe in G. ( B.) mauroi ). Gonioctena ( B.) kuatunensis sp. nov. differs in semicircular apex of aedeagus (triangular or subtriangular in other species).

Distribution. Vietnam: Vinh Phuc Province ( Fig. 13 View Fig ).

Remarks. The male genitalia of Gonioctena ( B.) flavipennis (Jacoby, 1888) illustrated by YANG et al. (2014) without any doubts refer to G. ( B.) medvedevi . The correct drawings of male genitalia of G. ( B.) flavipennis were provided by CHO & BOROWIEC (2016a).
