Eurypedus nigrosignatus is easily distinguished from E. peltoides by the shape of the prothorax and leg. In E. nigrosignatus , pronotal width at the broadest point is 1.3–1.4 times the length; in E. peltoides , width is 1.5–1.6 times the length. The posterior margin of the pronotal hypomeron is more emarginate than in E. peltoides ( Fig. 30 ). Protibial length in E. nigrosignatus is less than or equal to 2.5 times the width of the distal end; in E. peltoides , length is equal to or greater than 3 times the width of the distal end. Description. Adult (n=114) length 6.0– 9.5mm , width 3.0–5.0mm ( lectotype : length 7.5mm , width 3.7mm ). Pronotum ( Figs 3–5 , 9, 10) hemispherical, width at broadest point 1.3–1.4 times length; pronotal disc convex, with or without medial longitudinal furrow; posteromedial region of pronotum convex or flattened with shallow depression on each side; posterior margin of pronotal hypomeron concave, with depth about 0.5 times width of hypomeron at posterior margin. Elytra ( Figs 3–5 , 9) with length about1.4 times width, or shorter; submesal interval distinct on each elytron, marked by punctures and occasionally with black coloration; punctures on elytral disc with uniform size, forming striae; medial region of each elytral base convex with surface smooth, occasionally flattened. Tibiae ( Fig. 30 ) elongate, triangular in lateral view; length less than or equal to 2.5 times width of distal end. Aedeagus ( Figs 37–38 ) curved, slightly narrower apically; phallobase with length equal to or shorter than 0.3 times length of aedeagus; apex of median lobe broadly pointed, with angle over 90˚.
