Liuixalus

Romerus Dubois, Ohler & Pyron, 2021 Liuixalus is a small genus of rhacophorid frogs that are distributed in southern China (Hong Kong, Hainan, Guangxi, Guangdong).

[4] The genus name Liuixalus commemorates Liu Chengzhao [zh], a Chinese herpetologist.

[1] In 2021, another phylogenetic study deemed the name Liuixalus as invalidly proposed due to a lack of a diagnosis for the genus in the original study, and thus redescribed the genus as Romerus, alongside morphological characteristics distinguishing it.

[3] However, in 2023, the name was changed back to Liuixalus on the basis of Ren, Jiang & Li, who refuted the requirement for a genus name to have morphological characteristics associated with it.

[5] The International Union for Conservation of Nature (IUCN) has assessed two species of the genus as vulnerable (Liuixalus ocellatus and L. hainanus), one as endangered (L. romeri), and one as least-concern (L. feii), while Liuixalus shiwandashan is considered data deficient.
