Seroja Camp ( 04°39.415′N , 101° 16.333′E ), 3 July 2019 (GKA025–027, 051); Kijang Camp ( 04°40.482′N , 101°16.788′E ), 3 July 2019 (HC999–1000). Identification. Vomerine teeth present; a pair of boney, fang-like, mandibular processes anteriorly; tympanum present but obscured by skin; skin on dorsum smooth, flanks slightly rugose; supratympanic fold distinct; dor- solateral fold distinct anteriorly, becoming less pronounced posteriorly towards the groin; dorsum yellowish brown to dark gray; limbs with dark crossbars; venter yellow or orangish, gular region darkly mottled. These characters are in agreement with Dring (1979) . Remarks. Limnonectes tweediei and L . nitidus are morphologically similar, and the former was once considered a junior synonym of the latter ( Kiew 1975 ). However, L. tweediei was subsequently removed from that synonymy by Dring (1979) , who demonstrated significant morpho- logical and ecological differences between the two taxa, including body size ( L. tweediei are much smaller than L. nitidus ) and altitudinal distribution ( L. tweediei occurs up to ~ 900 m vs L. nitidus at ~ 1300 m ). The samples we collected fell within the size range of L. tweediei (adult males up to 41.8 mm SVL) and were collected between 800 and 1000 m a.s.l. Frogs were relatively common in shallow, stagnant, muddy/swampy puddles that have a thick bed of leaf litter away from main streams or rivers. Males were actively calling.
