Limnonectes tweediei (Smith, 1935)

Figure 8

Materials examined. 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.
