Specimens of the genus Eucorydia Hebard, 1929 from Chiang Mai, northern Thailand, were compared with eight closely similar congeners: E. aenea (Brunner von Wattenwyl, 1865), E. dasytoides (Walker, 1868), E. yunnanensis Woo, Guo, and Feng, 1986, E. pilosa Qiu, Che, and Wang, 2017, E. guilinensis Qiu, Che, and Wang, 2017, E. tangi Qiu, Che, and Wang, 2017, E. linglong Qiu, Che, and Wang, 2017, and E. tokaraensis Yanagisawa, Sakamaki, and Shimano, 2020, and turned out to be a different species from eight congeners. This species from Thailand is characterized by the specific male genitalia shape: right phallomere 2 (R2) slightly elongated, the basal left area of R2 forming a triangular protrusion, and the basal half of left phallomere 7 (L7) protruded to the left with long spatulate distal half and with a beak-like apex. This species is also characterized by the tegmina containing three orange markings in the middle, and with a pair of orange markings at its base. Based on the above, this species is described as a new species, Eucorydia asahinai sp. nov.
