HOLOTYPE of Eucorydia yunnanensis, male (SWU, IPP0155), CHINA: Yunnan: “Mengsong, Banna, Menglong, Yunnan” (Now Mengsong Township [勐宋乡], Menghai County [勐海县], Xishuangbanna Prefecture [西双版纳州]), 1600m, 24.IV.1958, Fu-Ji Pu leg.
Diagnosis
Eucorydia yunnanensis superficially resembles E. guilinensis sp. n., but the former can be distinguished from the latter by the following characters: 1) without any whitish pubescence on pronotum and tegmina (Fig. 7A, D), while mixed with many yellowish white pubescence on pronotum and the base of tegmina in E. guilineneis (Fig. 7H); 2) the orange band on tegmina is quite wide (Fig. 7A, D), while narrow in E. guilineneis (Fig. 7H); 3) hind margin of the concave part in supra-anal palte narrow (Fig. 8B, No. 1-2), while wide in E. guilineneis (Fig. 8D, No. 1-2); appendage sclerite less curved than that of E. guilineneis (Fig. 8B, No. 5 and 8 D, No. 5); R2 elongate, the left basal portion with a long protrusion (Fig. 8B, No. 6), while R2 short and round, and left basal portion with a short protrusion (Fig. 8D, No. 6).
