Additional material examined. See Appendix 1.

Diagnostic description. Body length 11.9–23.1 mm ( 21.9 mm in the lectotype), maximum body width 8.5– 11.9 mm ( 11.2 mm in the lectotype). Pronotum orange in dorsal view ( Figs. 5–6 ). Hypomeron medially orange in ventral view, dark metallic blue only along its posterior margin. Elytra brown to dark brown, without metallic luster; outline subrectangular; costae finer, less elevated ( Figs. 5–6 ).

Male. Elytra laterally parallel and more narrow than in N. brunnicollis ( Fig. 5 ). Metatibia only slightly bent. Male genital segment with longer spiculum gastrale in ventral view ( Fig. 43 ). Aedeagus with median lobe distinctly shorter than slender, elongate parameres in ventral view ( Figs. 42 ).

Female. Apex of elytron more elongated than in N. brunnicollis ( Figs. 6 , 66 ). Genital segment with tergum 10 large, pentagonal in shape, narrowly rounded posteriorly in dorsal view ( Fig. 44 ).

Notes on type specimens. Lectotype of Eusilpha cyaneocephala is designated here as a male from SDEI, selected from series of syntype specimens from SDEI, MNHN and NMNH.

Distribution ( Fig. 63 ). Endemic Taiwanese species (Portevin 1914, Nishikawa 2014).
