Diagnosis.

This species resembles Eucorydia guilinensis sp. n., but can be distinguished from the latter by the following characters: 1) body larger (15.9-16.3 mm) and broader (8.6-8.8 mm), while body small (13.8-14.2 mm) and narrow (7.0-7.2 mm) in E. guilinensis ; 2) the white pubescence on tegmina is mainly limited to the suture of left tegmen and 1/3 of basal anal area on both tegmina, while the pubescence more widely distributed at the base of tegmina in E. guilinensis ; 3) the concave part of supra-anal plate more straight (Fig. 10C, No. 1-2), while more round in E. guilinensis (Fig. 8D, No. 1-2); 4) the appendage sclerite with basal left protruded, distal margin of the protruded part straight (Fig. 10C, No. 5), while the appendage sclerite with basal left protruded and strongely curved toward posterior (Fig. 8D, No. 5).
