03878780FFCA2235FF6CFBE158C1F81D.taxon	discussion	Remarks. This new species is similar to Eupteryx (Stacla) janeki Dworakowska, 1969, but can be distinguished by the following morphological characters: aedeagal shaft with pair of small subapical processes on dorsal margin and pair of medial processes curved basolaterad (E. (S.) janeki lacks dorsal subapical processes and has a pair of elongate medial processes extended ventrad then strongly curved dorsad); subgenital plate medially concave (medially slightly convex in E. (S.) janeki).	en	Feng, Qian, Li, Zizhong, Song, Yuehua (2026): A new species of the genus Eupteryx Curtis, 1831 (Hemiptera: Cicadellidae: Typhlocybinae) from Thailand.
