Two new species of the genus Pseudidonauton Hering (Lepidoptera, Limacodidae), P. sinensis sp. nov. and P. puera sp. nov., are described from China. The new species are illustrated with images of the adults and male genitalia, and compared with similar species. Distribution maps of these species and a key to all known species of the genus are provided.

The specimens were collected with a 220V/450W mercury vapour lamp and a DC black light in southern China and Vietnam. Standard methods for dissection and preparation of the genitalia slides were used (

The new species is very similar to its congeners in appearance, especially to P. bhaga (Fig.
The male genitalia are clearly different from those of the other congeners: in P. sinensis sp. nov. (Figs

The species is named sinensis because of its wide distribution in China.
The specimens were collected from June to August at altitudes of 560–2,800 m.

The new species can be clearly distinguished from the known species in its appearance: the dark brown area at the base of the forewing has no obvious borderline with the ground colour and has no apical patch. In the male genitalia, the new species is similar to P. chihpyh (Fig.

The species is named puera (a noun in apposition) after its type locality in Puer City, Prov. Yunnan, China, which is famous for Puer tea.
The moths fly in late June and August. The Chinese specimens were collected with a light trap close to a coniferous forest; the main vegetation around the collecting site consists of Pinus yunnanensis Franch. (Pinaceae).

The genus Pseudidonauton comprises eight species in total to date, but the presence of P. admirabile in China is still unclear. It is possible that the record from southern China of this species by
In addition, two unidentified females of Pseudidonauton were collected from southern China (Guangdong and Hainan Province) in 2017 and 2019, respectively; the female from Hainan may belong to a species known from Vietnam. However, due to the lack of male specimens at present, we cannot accurately identify which species they belong to.
