Chresonymy.

Odorrana fengkaiensis Wang et al. 2015 .

Odorrana fengkaiensis — Pham et al. 2020.

Common name.

Fengkai Cascade Frog ( Pham et al. 2020)

Remarks.

Wang et al. (2015) described a distinct lineage, O. fengkaiensis , while citing similarity and a moderate level of mitochondrial sequence divergence (1.9–2.4 %) from O. hainanensis Fei, Ye & Li, 2001 . Although low to moderate genetic distances have been observed to indicate clear species boundaries in some species within Odorrana (e. g. O. jingdongensis and O. yunnanensis ) the validity of O. fengkaiensis in respect to some records reported from Vietnam has been questioned ( Poyarkov et al. 2021).

Wang et al. (2015) described O. fengkaiensis , based on the holotype specimen recorded from Heishiding Nature Reserve, Fengkai County, Guangdong Province, China. Pham et al. (2020) reported O. fengkaiensis from north-eastern Vietnam; however, this record was disputed as a likely misidentification with specimens of O. hainanensis by Poyarkov et al. (2021). We utilised sequences directly submitted to GenBank from northern Vietnam as O. bacboensis (GenBank accession numbers KX 893887 View Materials , voucher IEBR A.2015.83 ; KX 893888 View Materials , voucher VFUKH 073 and KX 893909 View Materials ; voucher IEBR 3942 ). These sequences were recovered within the true O. fengkaiensis subclade containing the paratype sequences with strong node support values ( BPP = 1; BS = 100) (see clade B). Odorrana hainanensis was recovered as a closely-related, but distinct lineage from O. fengkaiensis ( BPP = 1; BS = 99). However, to fully resolve the evolutionary relationship within these taxa, comprehensive geographic sampling across Vietnam and China, a careful re-examination of the voucher specimens and the use of genome-wide sequence data should be considered in the future.
