Tennentsia koreana n. sp. is the first representative of the family Dysmorphoptilidae described from the Upper Triassic of South Korea. This discovery extends the distribution of the genus Tennentsia in Asia and suggests that it was broadly distributed during the Triassic. Tennentsia koreana n. sp. differs from the other species currently included in the genus Tennentsia, inter alia, because of its tegmen not (or only slightly) emarginate at CuA, RA1 with a weak anterior branch, RA2 not strongly anteriorly curved, with two well-defined branches, strigil in basal part of costal space with coarse punctation.

Résumé. Le premier Dysmorphoptilidae (Insecta, Hemiptera) du trias Supérieur de Corée du Sud. Tennentsia koreana n. sp., est le premier représentant de la famille décrit du Trias supérieur de Corée du Sud. Cette découverte étend la distribution du genre Tennentsia en Asie et suggère qu'il était largement réparti durant le Trias. Tennentsia koreana n. sp. diffère des autres espèces actuellement incluses dans le genre Tennentsia, inter alia, car possédant un tegmen non (ou faiblement) émarginé au niveau de CuA, RA1 avec une branche antérieure faible, RA2 non fortement incurvée antérieurement, avec deux branches bien définies; et un strigile dans la partie basale de l'espace costal avec une ponctuation grossière.
