Meristogenys amoropalamus (Matsui, 1986)

Amolops amoropalamus: Matsui, 1986 , p. 628–629. figs. 1C, 1F, 2C, 2D; Meristogenys amoropalamus (larvae): Yang, 1991, p. 33–34; Malkmus et al., 2002, p. 149–150; Meristogenys sp. (lineage 1): Shimada et al., 2007a, pp. 173–189; Meristogenys amoropalamus (larval morphotype 1): Shimada et al., 2007b, pp. 59–63; Meristogenys amoropalamus (lineage 1): Shimada et al., 2011, p. 158–177, Fig. 3 , 4 , 6 .

Iris colour. Iris bicoloured, yellowish green above and reddish brown below. The upper part became dark yellow after anaesthesia.

Eggs. Ova bicoloured, heavy pigmentations on the animal pole, cream white on the plant pole; clutch size 400– 550; ovum diameter 2.1–2.6 mm.

Range. Besides the type locality (Gunung Tapai Sia; 1300 m a. s. l.), the adult of this species has been collected from Mesilau (1800 m) and Kamborangah (1800 m) in the Kinabalu National Park and Bario (1000 m) from Sarawak. The larvae of this species have also been collected from Mahua (1063 m), Liwagu (1500 m), and Trus Madi (Shimada et al., 2007b; altitude unknown). According to Yang (1991), tadpoles similar to this species had been collected from Sg. Panataran [Melangkap; FMNH (Field Museum of Natural History) 229861], Sg. Mesilau (Mesilau; FMNH 229862), Sg. Bambangan (Mamut; FMNH 229863), Sg. Kipungit (Poring; FMNH 130893), and Sg. Pegalan (FMNH 228007; J. Ladonski, pers. comm.).
