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).
