New species of the slug moths of the genera Pseudonagoda Holloway, 1990 and Prapata Holloway, 1990 (Lepidoptera, Zygaenoidea, Limacodidae) from Indochina

Three new species of Limacodidae from the genera Pseudonagoda and Prapata are described from the Indochina Peninsula. Pseudonagoda taynguyensis sp. nov. inhabits Central Vietnam and differs from its congeners in external appearance, male genitalia, and the COI barcode region. Two new species of Prapata, P. subhyalina sp. nov. and P. bannapapaeki sp. nov., are described from Central Vietnam and Northwestern Thailand, respectively.

Both species belong to the bisinuosa species group, which previously included a single species. The new Prapata species show clear differences from their congeners in male genitalia. Additionally, P. subhyalina sp. nov. has a distinctive external appearance, with extensive white translucent areas on the wings.

The COI barcode clearly distinguishes both new Prapata species from each other and from their congeners. The genus Pseudonagoda is recorded for the first time from the Indochina Peninsula and Vietnam, and Prapata from Thailand.
