bursae + corpus bursae. Ductus bursae very short; cervix bursae well-separated, somewhat mushroom-shaped. Corpus bursae ovate, membranous. Distribution - North Vietnam: Tarn Dao National Park. Diagnosis - The external appearance of the Taiwanese and the Vietnamese populations of Stenoloba yenminia RONKAY, 2001 are hardly comparable due to the rather poor condition of the specimens of the type series of the nominate S. yenminia. They differ, however, by the colouration of the characteristic tornai patch, which is more ochreous in the subspecies tamdaoensis than that of the subspecies yenminia, having more contrasting, whitish tornai macula. The male genital capsula of the two subspecies are similar in type, being different from all known Stenoloba (see RONKAY 2001), there are some small differences in the shape and size of the uncus (somewhat longer, more curved in the subspecies tamdaoensis), and the costal extension, which is larger, more triangular in case of the new subspecies. Both subspecies of Stenoloba yenminia are superficially similar to S. rufosagitta KONONENKO et RONKAY, 2001, known from Taiwan, South China and North Vietnam, and a part of the paratypes of this latter species was also collected in the Tarn Dao National Park. The forewing shape and colouration differ from those of S. rufosagitta by its blackish basal area well presented, and antemedian and postmedian line obscured. The comparison of the male genitalia with the related S. rufosagitta and S. oculata DRAUDT, 1950 is given in the original description of S. yenminia. The female genitalia are also easily distinguishable by the well-sclerotized long antrum and the characteristic shape of the cervix bursae of S. yenminia.
