( Figs 6 , 11 , 12 )

Gonioctena (Gonioctena) fujiana Cho & Borowiec, 2016: 178 (original description).

Gonioctena (Gonioctena) kamikawai: Yang et al. 2014: 364 (part); Yang et al. 2015: 50 (part) (misidentifications).

Type locality. China: Fujian Province, Guadun .

Type material. Holotype: ♂ ( NMPC), “ Cina, Fukien [= Fujian], Kuatun [= Guadun ], V.1946, leg. Tschung-Sen // HOLOTYPUS Gonioctena (s. str.) fujiana sp. n. Cho & Borowiec 2014” . Paratypes: 2 ♂♂ ( LMC, TLMF), same data as holotype plus “ PARATYPUS Gonioctena (s. str.) fujiana sp. n. Cho & Borowiec 2014” .

Diagnosis. This species is similar to G. jolantae new species and G. kamikawai, in that the pronotum has nine black spots and the elytral punctures are arranged in irregular single or double rows. However, G. fujiana can be distinguished by the following characters: irregular yellowish-brown marking on elytral humerus extending across half of elytral base (3/5 of base in G. jolantae new species, 1/3–3/5 of base in G. kamikawai ); median lobe parallelsided with apical process broader than shaft, lateral angles of process distinct (subparallel-sided with apical process narrower than median lobe, lateral angles of process rounded in G. jolantae new species; subparallel-sided with apical process narrower than the median lobe, lateral angles distinct in G. kamikawai ).

Distribution. China: Fujian ( Fig. 12 ).

Remarks. The illustrations of habitus and male genitalia of Gonioctena kamikawai of Yang et al. (2014) and Yang et al. (2015) certainly refer to G. fujiana . Gonioctena fujiana is endemic to Fujian and G. kamikawai is endemic to Taiwan.
