Material examined in this study was collected in the Tarn Dao National Park, 80 km NE of Hanoi, North Vietnam, during the entomological expeditions (2002-2004) carried out within the framework of an international collaborative work between Korea and Vietnam. The colour standard for the description of the adult follows KORNERUP & WANSCHER (1978). SYSTEMATIC PART Stenoloba yenminia tamdaoensis ssp. n. (Figs 1-6) Type material - Holotype, male: "N.

Male genitalia (Figs 2-3). Uncus long, weakly sclerotized, broad at base and narrowed towards apex; apex not pointed.
