Kalophrynus pleurostigma Tschudi, 1838, Classif. Batr.: 86. Type(s): RMNH; RMNH 2279 considered holotype by Gassó Miracle, van den Hoek Ostende, and Arntzen, 2007, Zootaxa, 1482: 47. Zug and Kaiser, 2013, Bull. Zool. Nomencl., 70: 86-88, requested that the ICZN permit designation of USNM 36645 as neotype inasmuch as the holotype is unidentifiable. This request not approved by Anonymous, 2017, Bull. Zool. Nomencl., 74: 127–129. Type locality: "Sumatra", Indonesia. Potential neotype from "'Aru Bay, East Sumatra' (approx. 98° 15′ E, 4° 10′ N, Sumatera, Utar Province", Indonesia. 

Bombinator pleurostigma Tschudi, 1838, Classif. Batr.: 86. Name attributed to Müller, coined as an objective synonym of Kalophrynus pleurostigma to reference jar label name of types in the RMNH.

English Names

Rufous-sided Sticky Frog (Grismer, 2012, Field Guide Amph. Rept. Seribuat Arch.: 52).


Known definitely from Sumatra (Indonesia); records require verification from southern Myanmar and Thailand, Malaya, Borneo, Java, and southern Philippines (including Mindanao and Cebu). Reported from Laut I., Natuna Is., Indonesia. See comment. 


All literature addressing populations away from Sumatra should be used with caution. See Inger, 1954, Fieldiana, Zool., 33: 416–420, for discussion of Philippine populations. Das, 2007, Amph. Rept. Brunei: 41, provided a photograph and a brief account for a population in Brunei. Matsui, Chan-ard, and Nabhitabhata, 1996, Copeia, 1996: 440–445, described the advertisement call. Chan-ard, Cota, and Makchai, 2011, Amph. E. Region Thailand: 129, detailed the distribution in Thailand (identification now unclear: DRF). Matsui, Nishikawa, Belabut, Ahmad, and Yong, 2012, Zootaxa, 3155: 38–46, noted that many records of this species from Singapore and Peninsular Malaysia are probably attributable to Kalophrynus limbooliati. See brief account by Grismer, 2012, Field Guide Amph. Rept. Seribuat Arch.: 52–53, for the Seribuat Archipelago, West Malaysia, and by Sumarli, Grismer, Anuar, Muin, and Quah, 2015, Check List, 11(4, Art. 1679): 9, who reported specimens from Lata Tembaka, Lata Belatan, and the base of Mount Lawit, Terregganu, West Malaysia, and briefly reported on their morphology and habitat. See account by Zug, 2015, Proc. California Acad. Sci., Ser. 4, 62: 173–175, who redelimited the species and suggested that the Javan population represents an unnamed species or that reports have been based on misidentifed Kalophrynus minusculusMatsui, Eto, Belabut, and Nishikawa, 2017, Curr. Herpetol., Kyoto, 36: 85, noted that records from the Malay Peninsula (and presumably including Singapore) actually represent Kalophrynus kiewi, and discussed uncertainties of identifications outside of Sumatra. Herlambang, Riyanto, Munir, Hamidy, Kimura, Eto, and Mumpuni, 2022, Treubia, 49: 78, discussed a report of the species from Laut I., Natuna Is., Indonesia.
