Phrynoidis asper (Gravenhorst, 1829)

Class: Amphibia > Order: Anura > Family: Bufonidae > Genus: Phrynoidis > Species: Phrynoidis asper

Bufo asper Gravenhorst, 1829, Delic. Mus. Zool. Vratislav., 1: 58. Types: Not stated. Largest specimen of RMNH 2172 (4 specimens originally, paralectotypes now 10681) designated lectotype by Inger, 1966, Fieldiana, Zool., 52: 66. M. Hoogmoed In Inger, 1985, In Frost (ed.), Amph. Species World: 36, doubted the validity of these specimens as Gravenhorst types, because Gravenhorst's specimens, although sent from the RMNH, are probably in the Breslau (= Vratislava) Museum. Nevertheless, Gassó Miracle, van den Hoek Ostende, and Arntzen, 2007, Zootaxa, 1482: 32, accepted RMNH 10681 as the lectotype. Type locality: "Java", Indonesia.

Comment

In the Bufo asper group of Martin, 1972, in Blair (ed.), Evol. Genus Bufo: 65, and Inger, 1972, in Blair (ed.), Evol. Genus Bufo: 107. See Taylor, 1962, Univ. Kansas Sci. Bull., 43: 326–329, Inger, 1966, Fieldiana, Zool., 52: 66–69, and Bourret, 1942, Batr. Indochine: 176–178, for synonymy and discussion; also see Berry, 1975, Amph. Fauna Peninsular Malaysia: 46–47, for account. Yang, Liu, and Rao, 1996, Zool. Res., Kunming, 17: 356, suggested that Bufo asper might be in the genus Torrentophryne. This was not accepted by Rao, Yang, and Wang, 1998, Russ. J. Herpetol., 5: 67. Further, if Bufo asper is included in Torrentophryne, it brings with it an older generic name Phrynoidis Fitzinger, 1843, which would be a subjective senior synonym of Torrentophryne. See account by Iskandar, 1998, Amph. Java Bali: 45–46. See brief account and photo by Manthey and Grossmann, 1997, Amph. Rept. Südostasiens: 31. Orlov, Murphy, Ananjeva, Ryabov, and Ho, 2002, Russ. J. Herpetol., 9: 84, provided the Vietnam record. Nutphund, 2001, Amph. Thailand: 71, provided a brief characterization and photograph and suggested that the species is found throughout Thailand. Chan-ard, 2003, Photograph. Guide Amph. Thailand: 90–91, provided a very brief account, map for Thailand, and photograph. 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. Das, Jankowski, Makmor, and Haas, 2007, Mitt. Hamburg. Zool. Mus. Inst., 104: 148, provided a brief description. Das, 2007, Amph. Rept. Brunei: 26, provided a photograph and a brief account (as Bufo asper). See brief account by Grismer, 2012, Field Guide Amph. Rept. Seribuat Arch.: 44–45, for the Seribuat Archipelago, West Malaysia. Schmidtler, 2013, Herpetozoa, Wien, 26 : 15–26, discussed the original description of this species.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 from Lata Tembaka, Terregganu, West Malaysia, and and reported on natural history and life history. Amram, Zainudin, and Wahid, 2018, Sains Malaysiana, 47: 1–7, reported on the mating call. Zug and Mulcahy, 2020 "2019", Amph. Rept. S. Tanintharyi: 29–30, provided a brief account for South Tanintharyi, peninsular Myanmar. See brief account for East Java by Amin, 2020, Frogs of East Java: 37–40.
