Class: Amphibia > Order: Anura > Family: Ranidae > Genus: Hylarana > Species: Hylarana leptoglossa

Hylorana leptoglossa Cope, 1868, Proc. Acad. Nat. Sci. Philadelphia, 20: 140. Syntypes: MCZ 623 (3 specimens) according to the original publication; MCZ 1588 (3 specimens, renumbered), according to Barbour and Loveridge, 1929, Bull. Mus. Comp. Zool., 69: 282. Type locality: "near Rangoon, Burmah".

Hylorana granulosa Anderson, 1871, J. Asiat. Soc. Bengal, 40: 23. Syntypes: Not stated; ZSIC 2789–90, 4009, 10830, according to Annandale, 1917, Mem. Asiat. Soc. Bengal, 6: 142, although earlier Sclater, 1892, List Batr. Indian Mus.: 9, listed only the 2789–90 as "cotypes". Chanda, Das, and Dubois, 2001 "2000", Hamadryad, 25: 105, considered only ZSIC 2789-90 and 4009 as syntypes, rejected 10830 as a syntype following Sclater, 1892, List Batr. Indian Mus.: 9. Type localities: "Pegu" (= Bago, southern Myanmar) and "Seebaugor, Assam" (= Sibsigar, Assam), India. Synonymy by Boulenger, 1920, Rec. Indian Mus., 20: 145, 148.

Prior to the revision of Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297, placed in the Section Hylarana, subsection Hydrophylax, subgenus Sylvirana of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 326, although this taxonomy is now superseded. See accounts (as Rana (Hylarana) leptoglossa) by Boulenger, 1920, Rec. Indian Mus., 20: 145; Bourret, 1942, Batr. Indochine: 314–316. Chanda, 2002, Handb. Indian Amph.: 121, provided a brief account. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 90, rejected the occurrence of this species in Vietnam, considering that record likely a misidentified Rana nigrovittata. Nutphund, 2001, Amph. Thailand: 101, provided a brief characterization and photograph (which Ohler, 2003, Alytes, 21: 101, did not consider identifiable beyond the association with Sylvirana). Chan-ard, 2003, Photograph. Guide Amph. Thailand: 130–131, provided a very brief account, map for Thailand, and photograph. Dutta, 1997, Amph. India Sri Lanka: 159–160, provided range, systematic comments, and partial taxonomic bibliography. Mahony and Reza, 2007, Herpetol.

NE India: 45, provided a brief account for northeastern India. Das and Dutta, 2007, Hamadryad, 31: 154–181, noted no larval descriptions in the literature. Mathew and Sen, 2010, Pict. Guide Amph. NE India: 81, provided a brief characterization and photograph and suggested that the species had been recorded in Vietnam. Bortamuli, Bordoloi, Ohler, and Grosjean, 2010, J. Nat. Hist., London, 44: 421–445, described external and buccopharyngeal anatomy. Mahony, Hasan, Kabir, Ahmed, and Hossain, 2009, Hamadryad, 34: 80–94, provided a new record for Bangladesh and discussed the known range in that country. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 145, detailed the range in Thailand. Hasan, Khan, and Sumida, 2011, Herpetol.

Contrib. Zool., 653: 37, briefly discussed identification, habitat, and range in Myanmar.
