Notes on South-East Asian Limacodidae (Lepidoptera, Zygaenoidea) with one new genus and eleven new species Alexey V. Solovyev Eleven new species of Limacodidae from South-East Asia are described here as new: Barisania honeyi sp. n. from central Myanmar, northern and central Vietnam and central Thailand, Pseudaltha eboris sp. n., from northern Thailand, P. sapa sp. n., from northern Vietnam and northern Thailand, Austrapoda seres sp. n. from China (Chekiang and Shaanxi), Euphlyctinides indi sp. n. from India, E. aeneola sp. n. from northern and western Thailand, Pseudonagoda siniaevi sp. n. from southern Andaman, Atosioides accola sp. n. from western Sumatra and southern Thailand, Pseudidonauton siamica sp. n. from northern Thailand and central Vietnam, P. chihpyh sp. n. from Taiwan and P. vexa sp. n. from central Vietnam and south- eastern Thailand. The genus Atosioides Solovyev is erected here with type-species Atosia rochei Holloway, 1986. Brief morphological reviews of all examined genera are given. All diagnostic features are illustrated.
