Gonioctena (Asiphytodecta) mausonensis Cho & Borowiec, 2016: 169 (original description).

Type locality. Vietnam, Lang Son Province, Loc Binh, Mt. Mau Son.

Type material examined. HOLOTYPE: ♂, ‘ Tonkin, Montes Mauson,April, Mai 2-3000’, H. Fruhstorfer // 24 // Jacoby Coll.1909-28a. // flavoplagiata Jac. // HOLOTYPUS Gonioctena (Asiphy.) mausonensis sp. n. Cho & Borowiec 2014’ ( BMNH). PARATYPE: 1 ♂, ‘ Tonkin, Montes Mauson,April, Mai 2-3000′, H. Fruhstorfer // PARATYPUS Gonioctena (Asiphy.) mausonensis sp. n. Cho & Borowiec 2014’ ( LMCM).

Description. See CHO & BOROWIEC (2016).

Differential diagnosis. Gonioctena (A.) mausonensis can be easily distinguished from G. (A.) eburoides , G. (A.) flavoplagiata , G. (A.) jindrai sp. nov. and G. (A.) truncaticornis sp. nov. by its reddish-brown venter and subdiamond-shaped apical process of aedeagus ( Fig. 26 ).

Distribution. Vietnam: Lang Son ( Fig. 29 ).

Remarks. The male genitalia of Gonioctena (A.) flavoplagiata illustrated by YANG et al. (2014) without any doubts refer to G. (A.) mausonensis . The correct drawings of male genitalia of G. (A.) flavoplagiata were provided by CHO & BOROWIEC (2016).
