Limnonectes limborgi (Sclater, 1892)

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

Rana limborgi Sclater, 1892, Proc. Zool. Soc. London, 1892: 344. Holotype: ZSIC by original designation; ZSIC 5400 according to Sclater, 1892, List Batr. Indian Mus.: 4; lost according to Inger and Stuart, 2010, Curr. Herpetol., Kyoto, 29: 57, who designated as neotype MSNG 29422. Type locality: "Tenasserim", Myanmar; given as "Meetan, Tenasserim" by XXX; neotype from "Karin Bia-po, Myanmar (19° 03´N/ 96° 30´ E)"; this regarded as erroneous by Köhler, Zwitzers, Than, Gupta, Janke, Pauls, and Thammachoti, 2021, Diversity, 13 (399): 2, who identified the neotype locality as currently named "Leiktho [Kayin State, Myanmar] and is located at 19.2212, 96.5818, 865–885 m above sea level."

Distribution

Northwestern Thailand and southeastern (non-peninsular) Myanmar; records from outside of this area may apply to unnamed species (see comment): northern Myanmar south and east through peninsular Myanmar, northern Thailand with isolated records in southern peninsular Thailand and peninsular Malaysia, Laos, Vietnam (Lao Cai and Quang Ninh provinces south to Dong Nai and Kien Giang provinces) and northeastern Cambodia; likely to be found in adjacent Yunnan and Guangxi, China, and border region of northeastern India.

Comment

Removed from the synonymy of Limnonectes hascheanus by Dubois, 1987 "1986", Alytes, 5: 64, where it had been placed by Smith, 1929, Rec. Indian Mus., 31: 77. See Bourret, 1942, Batr. Indochine: 274, for literature access. Stuart, 1999, in Duckworth et al. (eds.), Wildlife in Lao PDR: 45, reported the species in Laos. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 142–143, provided a very brief account, map for Thailand, and photograph. Inger and Stuart, 2010, Curr. Herpetol., Kyoto, 29: 51–68, reported on the systematics of this species (which they suggested may be composed of several species) and the closely related Limnonectes limborgi and redelimited the ranges of both, thereby rendering doubtful identifications in a considerable amount of previous literature. Bain, Nguyen, and Doan, 2007, Herpetol. Rev., 38: 109, provided records from Thua Thien-Hue, Nghe An, and Lam Dong Provinces, Vietnam (as Limnonectes hascheanus). Nguyen, Ho, and Nguyen, 2005, Checklist Amph. Rept. Vietnam: 32, provided specific localities for Vietnam (as Limnonectes hascheanus). Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 136, detailed the range in Thailand. See account, photograph, and map for Vietnam in Vassilieva, Galoyan, Poyarkov, and Geissler, 2016, Photograph. Field Guide Amph. Rept. Lowland S. Vietnam: 92–93. Mulcahy, Lee, Miller, Chand, Thura, and Zug, 2018, ZooKeys, 757: 95, provided a genetically confirmed record from Taninthary Department, southern Myanmar. Pham, Phan, Do, and Nguyen, 2019, Tap-Chi-Sinh-Hoc, 41 (2se1&2se2): 172–173, reported collection sites in Kon Tum and Quang Ninh provinces, Vietnam, and described the specimens (noting differences from Limnonectes haschenaus), provided ecological notes, and summarized the range in Vietnam by province. Zug and Mulcahy, 2020 "2019", Amph. Rept. S. Tanintharyi: 37–38, provided a brief account for South Tanintharyi, peninsular Myanmar. Pham, Do, Ngo, Tran, Ziegler, and Nguyen, 2020, Check List, 16: 1025–1041, provided a record from Hai Ha District, Quang Ninh Province, Vietnam, on the Guangxi, China, border. Makchai, Chuaynkern, Safoowong, Chuachat, and Cota, 2020, Amph. N. Thailand: 62, provided photographs, a brief account for Thailand, and a range map. Le, Luong, Pham, Phan, Nguyen, Ziegler, and Nguyen, 2021, Bonn Zool. Bull., 70: 201–219, provided natural history notes and a record from Tuyen Quang Province, Vietnam. Poyarkov, Nguyen, Popov, Geissler, Pawangkhanant, Neang, Suwannapoom, and Orlov, 2021, Russ. J. Herpetol., 28 (3A): 24, repeated Inger and Stuart's (2010) statement that this is likely a species complex. Köhler, Zwitzers, Than, Gupta, Janke, Pauls, and Thammachoti, 2021, Diversity, 13 (399): 1–35, recognized 9 16S mtDNA clades within the nominal species, of which they named Clade 6 (Bagoyoma region of southern Myanmar) as Limnonectes bagoyoma and the applied the name Limnonectes limborgi to their Clade 7 from northwestern Thailand and southeastern (non-peninsular) Myanmar; the rest of the range they regarded as likely composed of the remaining 7 16S mtDNA lineages. Pretty clearly nuDNA, advertisement call, and morphological evidence is required to elucidate this complex.
