Malaysian Bubble-nest Frog
(Figs. 1–2, 4, 7; Tables 1, 3)
Original name and description. Chiromantis marginis Chan, Grismer, Anuar, Quah, Grismer, Wood, Muin, and Ahmad 2011. Chan K. O., Grismer L.L., Anuar S., Quah E., Grismer J. L., Wood P. L. Jr., Muin M.A., and Ahmad N. 2011. A new species of Chiromantis Peters 1854 (Anura: Rhacophoridae) from Perlis State Park in extreme northern peninsular Malaysia with additional herpetofaunal records for the park. Russian Journal of Herpetology, 18: 253–259. Type. Holotype, LSUHC 9700, by original designation. Type locality. “from the dam behind Perlis State Park chalets, Perlis ”, Peninsular Malaysia. Current status of specific name. Valid name as Rohanixalus marginis (Chan, Grismer, Anuar, Quah, Grismer, Wood, Muin, and Ahmad 2011) comb. nov.
Taxonomic remarks. This taxon was described based on a single specimen from Peninsular Malaysia. Although the species was originally assigned to genus Chiromantis (= Chirixalus), it is morphologically closer to members of the genus Rohanixalus, primarily due to the following characters: prominent and dense minute speckles throughout the dorsum, lateral surfaces, and dorsal surface of limbs (vs. absent); and presence of light coloured dorsolateral stripes beginning from the snout tip, extending over the upper eyelid margins, and ending close to the vent on either side (vs. faint to prominent dorsal lines or absent). Further, the close relationship of R. marginis with R. hansenae, R. punctatus and R. vittatus was also originally suggested (Chan et al. 2011). However, the comparison of R. marginis with R. punctatus is considered weak as the degree of prominence of dorsal spots and dorsolateral stripes is variable among R. punctatus individuals. Rohanixalus marginis is also morphologically close to R. baladika and R. nauli (see taxonomic remarks under R. baladika for detailed discussion). Hence, based on available evidence, we formally reallocate Chiromantis marginis Chan, Grismer, Anuar, Quah, Grismer, Wood, Muin, and Ahmad 2011 (= Chirixalus marginis) to the genus Rohanixalus, as Rohanixalus marginis (Chan, Grismer, Anuar, Quah, Grismer, Wood, Muin, and Ahmad 2011) comb. nov. Further molecular studies can clarify the relationship of R. marginis with other Rohanixalus members, especially R. punctatus, with which it could be closely related based on morphological and geographical considerations (see taxonomic remarks under R. punctatus for further discussion).
Diagnosis. Small-sized adults (male SVL 23 mm) with slender body; tympanum indistinct, vomerine teeth absent; dorsal colouration greyish-white; the entire dorsum, lateral surfaces, and dorsal surface of limbs covered with fine dark brown speckles, some speckles clumping together to form dark irregular blotches or reticulation on the dorsum; a pair of narrow continuous dorsolateral stripes starting from the snout tip, extending over the eyes, and ending close to the vent on either side; webbing absent between fingers I, II, and III, basal webbing present between fingers III and IV; foot webbing moderate, up to the second subarticular tubercle on either side of toe IV.
Distribution. Rohanixalus marginis is currently known only from its type locality, Perlis State Park in Peninsular Malaysia.
