title: Sundapolystoma chalconotae n. g., n. sp. (Monogenea: Polystomatidae) from Rana chalconota (Schlegel) of Peninsular Malaysia.
abstract: Sundapolystoma chalconotae. n. g., n. sp. (Polystomatidae, Polystomatinae) is proposed for a new polystomatid from the urinary bladder of Rana chalconota (Schlegel) in Peninsular Malaysia. This is the first species of polystomatid to be described from the amphibians of Peninsular Malaysia and the second for the Southeast Asian region. This new genus, as exemplified by S. chalconotae, differs from other polystomatids, and in particular Parapolystoma Ozaki, 1935 (P. bulliense (Johnston, 1912) Ozaki, 1935 and P. johnstoni Pichelin, 1995), in having a tubular uterus and a single diffuse testis. P. crooki Vande Vusse, 1976 is similar to S. chalconotae in having a similar type of uterus and testis, and is re-assigned as Sundapolystoma crooki (Vande Vusse, 1976) n. comb. S. chalconotae differs from S. crooki in having anchors with a longer outer root rather than a longer inner root and 7-8 genital spines compared to 9-13 in S. crooki.
