Comment

Removed from the synonymy of Pelophylax plancyi (as Rana) by Kuramoto, 1983, Sci. Rep. Lab. Amph. Biol. Hiroshima Univ., 6: 253-267, where it had been placed by Shannon, 1956, Herpetologica, 12: 36. See comments under Pelophylax plancyi. Ueda, 1994, Sci. Rep. Lab. Amph. Biol. Hiroshima Univ., 13: 197-232, noted that Pelophylax plancyi plancyi, Pelophylax plancyi chosenicus, and Pelophylax plancyi fukienensis (all as Rana) had three distinct call types. Nishioka, Okumoto, and Ryuzaki, 1987, Sci. Rep. Lab. Amph. Biol. Hiroshima Univ., 9: 161, noted some reduced fertility between Pelophylax chosenicus and Pelophylax fukienensis (as subspecies of Pelophylax plancyi). See english summary of morphology (as Rana nigromaculata coreana) by Okada, 1928, Annot. Zool. Japon., 11: 270-271. Yang, Kim, Min, and Suh, 2001, Monogr. Korean Amph.: 68-69, provided a brief account, figure, and map for South Korea (as Rana plancyi). Ra, Sung, Cheong, Lee, Eom, and Park, 2008, Zool. Sci., Tokyo, 25: 894-903, reported on conservation biology. See photograph, map, description of geographic range and habitat, and conservation status (as Rana chosenica) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 503. Ra, Park, Cheong, Kim, and Sung, 2010, Zool. Sci., Tokyo, 27: 396-401, reported on habitat preference and conservation biology. Dot map and discussion of status for North Korea provided by Song, 2016, J. Natl. Park Res., Rep. Korea, 7: 211–217. Borzée, Litvinchuk, Ri, Andersen, Nam, Jon, Man, Choe, Kwon, Othman, Messenger, Bae, Shin, Kim, Maslova, Luedtke, Hobin, Moores, Seliger, Glenk, and Jang, 2021, Animals, 11 (2057): 1–37, provided locality records, a distribution map as well as modeled distribution, life history comments, and conservation status for P.D.R. Korea. Dufresnes and Litvinchuk, 2022, Zool. J. Linn. Soc., 195: 727, placed Pelophylax chosenicus into the synonymy of Pelophylax plancyi on the basis of low genetic distances. The species is provisionally retained here based on the seeming resistance to this taxonomic change among Asian workers and pending a more detailed review of the taxonomic issue. Zhou, Zhang, Wang, Miao, Xu, Guan, and Shi, 2022, Chinese J. Zool., 57: 440–446, provided a genetically confirmed record from Shenyang, Liaoning, northeastern China. Andersen, Chuang, Choe, Kim, Kwon, Jang, and Borzée, 2022, Zool. Stud., Taipei, 61(25): 1–10, reported on the elevational range (0–494 m) in Rep. Korea.
