Type material examined.

HOLOTYPE of Eucorydia xizhangensis , male (SWU, IPP0156), CHINA: Tibet: Beibeng Township [背崩乡], Motuo County [墨脱县], Nyingchi City [林芝市], 800-1200m, 10.VI.1983, Yin-Heng Han leg.

Diagnosis.

This species resembles E. splendida sp. n. and E. hilaris , but can be easily distinguished by its tegmina marking pattern, the basal metallic portions of E. xizangensis are much reduced, while the latter two have the basal portion of tegmina widely metallic bluish green. E. xizangensis can also be easily distinguished from E. splendida by: 1) hind margin of supra-anal plate straight (Fig. 10A, No. 1-2), while concave in E. splendida (Fig. 10B, No. 1-2); 2) L3 with apex less hooked (Fig. 10A, No. 3), while L3 strong hooked in E. splendida (Fig. 10B, No. 3); 2) R2 with an elongate irregular process on the left, apex of the process curved (Fig. 10A, No. 6), while R2 normally protruded toward left in E. splendida (Fig. 10B, No. 6).
