7 August 2021: Transferred Limnonectes rhacoda into Occidozyga (Dicroglossidae) on the basis of mtDNA evidence provided by Flury, Haas, Brown, Das, Min, Kueh, Scheidt, Iskandar, Jankowski, and Hertwig, 2021, Mol. Phylogenet. Evol., 163 (107210): 1–17, as part of a general investigation of Occidozyga phylogenetics and species boundaries within Sundaland. Nevertheless, the specimens identified by Flury et al. (2021) as Occidozyga rhacoda are from within the range (Sarawak, Malaysia) of the recently named Occidozyga berbeza (not adressed by Flury et al.) and not from the previously known range (central Kalimantan, Indonesia) of the externally similar Limnonectes rhacoda, which suggests the possibility that the generic name change of Limnonectes rhacoda to Occidozyga may be based on a mistaken identification which requires confirmation. An examination of the mandibular symphysis and tongue morphology (detailed by Matsui, Nishikawa, Eto, Hamidy, Hossman, and Fukuyama, 2021, Zootaxa, 4926: 535–546, as characters that separate the two genera) of the Sarawak population would probably be sufficient to resolve the issue.
