New species of Oswaldofilaria (Nematoda; Filarioidea; Onchocercidae) and other helminths in Acanthosaura cardamomensis (Sauria; Agamidae) from Indochina Peninsula.

Oswaldofilaria acanthosauri sp. nov. from the body cavity of the Cardamom Mountain horned agamid, Acanthosaura cardamomensis (Sauria: Agamidae), collected in Pursat Province, Cambodia is described. Of the 14 species assigned to Oswaldofilaria, O. acanthosauri sp. nov. is most similar to those species with spicular ratio of less than 2, namely, O. brevicaudata and O. chlamydosauri. Oswaldofilaria acanthosauri sp. nov. is easily separated from these 2 species in that O. brevicaudata is a South American species and in O. chlamydosauri the distal ends of the spicules are pointed not blunt. Mature individuals of 2 additional species of Nematoda, Meteterakis singaporensis and Orneoascaris sandoshami, as well as larvae assignable to Ascariidae were found. Acanthosaura cardamomensis represents a new host record for Meteterakis singaporensis, Orneoascaris sandoshami and Ascariidae (larvae).
