Geographic Occurrence

Natural Resident: Indonesia

Endemic: Indonesia


Removed from the synonymy of Meristogenys jerboa by Iskandar, 1998, Amph. Java Bali: 62 (who provided an account), where it had been placed by Boulenger, 1893, Ann. Mus. Civ. Stor. Nat. Genova, Ser. 2, 13: 335; Boulenger, 1920, Rec. Indian Mus., 20: 196; Van Kampen, 1923, Amph. Indo-Austral. Arch.: 208; Bourret, 1942, Batr. Indochine: 382. Redescribed and discussed by Stuart and Chan-ard, 2005, Copeia, 2005: 280–282. Bossuyt, Brown, Hillis, Cannatella, and Milinkovitch, 2006, Syst. Biol., 55: 579–594, found this species to be closely related to Meristogenys ; Che, Pang, Zhao, Wu, Zhao, and Zhang, 2007, Mol. Phylogenet. Evol., 43: 1–13, implied that this placement suggested that Huia is polyphyletic. Stuart, 2008, Mol. Phylogenet. Evol., 46: 54, considered this taxon to be in a clade composed of Meristogenys, Clinotarsus, and Odorrana and preferred not to place this taxon prior to phylogenetic analysis. See photograph, map, description of geographic range and habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 479. See brief account by Amin, 2020, Frogs of East Java: 20–22. Idrus, Arroyyan, Bahri, and Hamidy, 2021, J. Biodjati, 6: 1–10, reported on comparative morphometrics. Badriah, Wahyuni, Usman, Mahrawi, Ratnasari, and Rifqiawati, 2022, Berkala Ilmiah Biologi, 13 (3): 1–8, reported specimens from Ujong Kulon National Park, extreme western Java, Indonesia.
