44) by its longer, larger, rather triangular uncus, longer, narrower, sclerotized tegumen, long, narrowly V-shaped vinculum, longer and much narrower valvae with well-developed, triangular costal extension, pointed, densely hairy cucullus without sclerotized peak or setae, etc. The aedeagus of S. yenminia is longer, more tubular, than that of S. oculata, tapering distally, the vesica is broadly tubular, recurved, helicoid, coiling into one and half coils, almost completely membranous, only very weakly scobinate, with a weak, long sclerotized subterminal bar in inner curve of the second coil. The male genitalia of S. yenminia differ conspicuously from those of S. rufosagitta (see KONONENKO & RONKAY 2001, Figs 32-33) by their much narrower, sclerotized tegumen, long, V-shaped vinculum, longer, narrower valva with large costal lobe but without apical process, absence of saccular extension and the much longer, narrowly tubular, helicoid vesica, without any armature (the vesica of S. rufosagitta is armed with two fields of short but strong cornuti). Description - External appearance. Wingspan: 26-27 mm, length of forewing 12-13 mm. Forewing ground colour dark greyish brown with distinct whitish patch at tornus. Reniform stigma elliptical, encircled with fine blackish line; postmedial line double, fine, strongly arched around reniform. Subterminal line pale, diffuse, indistinct; terminal line dotted; cilia brown. Hindwing unicolorous, dark brown; discal spot not traceable; cilia also brownish. Underside of forewing uniformly dark brown; hindwing ochreous-greyish, irrorated strongly with dark brown scales, discal spot present, small, crosslines diffuse, wide, marginal area also darkened. Male genitalia (Fig. 11). Uncus relatively large, flattened, broadly triangular with apex pointed. Tegumen narrow, rather long, sclerotized, with well-developed penicular lobes. Vinculum long, sclerotized, V-shaped; juxta deltoidal, long, rather narrow. Valva long, narrow, sclerotized, with well-developed, triangular costal extension at medial third. Sacculus long, somewhat broader than most parts of valva, with densely setose plate at place of clavus and with smoothly sclerotized apical plate. Medial third of valva with sclerotized medial crest ("ampulla"), cucullus narrow, triangular with finely pointed apical lobe ventrally, covered densely with short hairs. Aedeagus long, tubular, broad basally, tapering distally, carina with finely sclerotized, pointed dorsal and ventral plates. Vesica broadly tubular, helicoid with one and half coils, recurved around carina. Its walls membranous with very fine scobination only, inner curve of the second coil with weak, long, finely sclerotized bar. Bionomics and distribution —The life history of the species is poorly known, the three known specimens were collected in two subsequent nights with light trap at one of the LTER (= "Long Term Ecological Studies") sites of the Fu-Shan Botanical Garden. Etymology - The new species is dedicated to Mrs YEN-MlN KUO, collection manager of the Lepidoptera collection of the TFRI, Taipei.
