Class: Amphibia > Order: Anura > Family: Dicroglossidae > Subfamily: Dicroglossinae > Genus: Limnonectes > Species: Limnonectes blythii

Rana fusca Blyth, 1856 "1855", J. Asiat. Soc. Bengal, 24: 719. Types: Not stated; presumably ZSIC; 3 specimens according to Emerson and Ward, 1998, Zool. J. Linn. Soc., 122: 544. Sclater, 1892, List Batr. Indian Mus.: 4, mentioned ZSIC 9076-85 (2 adults and 8 tadpoles), of which only ZSIC 9077 was located by Chanda, Das, and Dubois, 2001 "2000", Hamadryad, 25: 109. Type locality: "Tenasserim valley", Myanmar, although Sclater, 1892, List Batr. Indian Mus.: 4, gave "Pegu" (= Bago, Myanmar), as the locality of the syntypes. Junior homonym of Rana fusca Roessel, 1758, and Rana fusca Meyer, 1795. Considered incertae sedis within the Limnonectes grunniens group by Dubois, 1987 "1986", Alytes, 5: 63.

Rana (Rana) macrodon var. blythii Boulenger, 1920, Rec. Indian Mus., 20: 43-45. Replacement name for Rana fusca Blyth, 1855.

Myanmar through western and peninsular Thailand through Malaya to Sumatra and Borneo (Indonesia); records for Laos and Vietnam are apparently based on misidentifications (see comment).


In the Limnonectes (Limnonectes) grunniens group of Dubois, 1987 "1986", Alytes, 5: 63. See accounts by Boulenger, 1920, Rec. Indian Mus., 20: 43; Taylor, 1962, Univ. Kansas Sci. Bull., 43: 386-390; and by Inger, 1966, Fieldiana, Zool., 52: 162-175, who removed this species from the synonymy of Rana macrodon, where it had been placed by Boulenger, 1912, in Robinson (ed.), Vert. Fauna of the Malay Peninsula: 233; and Berry, 1975, Amph. Fauna Peninsular Malaysia: 77. See also Dring, 1979, Bull. Brit. Mus. (Nat. Hist.), Zool., 34: 197, whose stated distribution excluded Indochina north of Changwat Tak, Thailand. See comment under Limnonectes leporinus. See comments by Inger, Orlov, and Darevsky, 1999, Fieldiana, Zool., N.S., 92: 16-18, who noted that the Vietnam samples (presumably misidentified Limnonectes poilani) differed significantly from the Malayan populations. Emerson and Ward, 1998, Zool. J. Linn. Soc., 122: 537-553, presented molecular evidence that "Rana blythii" is a paraphyletic complex of species distributed phylogenetically throughout the Limnonectes grunniens group and this is consistent with the results of Chen, Murphy, Lathrop, Ngo, Orlov, Ho, and Somorjai, 2005, Herpetol. J., 15: 237. See brief account and photo by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 93-95. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 87, reported the species in central Vietnam and Laos, but also reported it in Philippines, casting some doubt of identification. Further, Nutphund, 2001, Amph. Thailand: 105, provided a brief characterization and photograph (as Rana blythii). Stuart, 1999, in Duckworth et al. (eds.), Wildlife in Lao PDR: 45, reported the range in Laos along with a statement of the lack of taxonomic clarity in that country. Stuart, Sok, and Neang, 2006, Raffles Bull. Zool., 54: 129-155, considered the Laos record as based on misidentified Limnonectes poilani. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 114-115, provided a very brief account, map for Thailand, and photograph. Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 21, provided specific localities for Vietnam and (p. 148) and a photograph. (These records based on misidentifications—R. Bain, personal commun.). Reported for Pulau Langkawi, Kadeh, northwestern West Malaysia, by Grismer, Youmans, Wood, Ponce, Wright, Jones, Johnson, Sanders, Gower, Yaakob, and Lim, 2006, Hamadryad, 30: 61-74. On the basis of an mtDNA study of phylogeny, Zhang, Nie, Peng, Ge, Wang, Xu, and Tang, 2005, Acta Zool. Sinica, 51: 354-359, suggested that Limnonectes blythii is polyphyletic, with the population in southern Borneo (Kalimantan, Indonesia) more closely related to Limnonectes leporinus, and the remainder of the populations involved complexly with Limnonectes paramacrodon, Limnonectes macrodon, and a group composed of Limnonectes ingeri and Limnonectes malesianus. See brief account by Grismer, 2012, Field Guide Amph. Rept. Seribuat Arch.: 67-68, for the Seribuat Archipelago, West Malaysia. Shahriza and Ibrahim, 2014, Check List, 10: 253–259, provided a photograph and brief natural history observations for a population in Kedah, West Malaysia. Sumarli, Grismer, Anuar, Muin, and Quah, 2015, Check List, 11(4, Art. 1679): 8, reported specimens from the base of Mount Lawit and Mount Tebu, Terregganu, West Malaysia, and and reported on natural history and life history. Haas, Kueh, Joseph, bin Asri, Das, Hagmann, Schwander, and Hertwig, 2018, Evol. Syst., 2: 89–114, noted records of this species from Sabah, Malaysia, that actually apply to Limnonectes leporinus. See comments on morphology in West Malaysia by Chan, Muin, Anuar, Andam, Razak, and Aziz, 2019, Check List, 15: 1055–1069. Zug and Mulcahy, 2020 "2019", Amph. Rept. S. Tanintharyi: 36–37, provided a brief account for South Tanintharyi, peninsular Myanmar. Hui, Ngadi, Md-Zain, Md-Zairi, and Abdul-Latiff, 2020, Biodiversitas, 21: 2425-2429, reported the species from Pulau Tinggi, off the southeastern coast of peninsular Malaysia.
