Original Article


Meteterakis asansolensis sp. nov. (Nematoda: Heterakidae) recovered from the rectum of Asian common toad, Duttaphrynus melanostictus (Schneider, 1899), collected from Asansol coalfield area in Paschim Bardhaman district of West Bengal, India, is described and illustrated. This species is characterised by the presence of a precloacal sucker, a gubernaculum and two equal and similar spicules (0.31–0.32 mm in length). This species differs from other reported species of the Oriental region by morphometrical ranges of measurements of males (3.09–3.54 mm) and females (4.60–4.72 mm) and the number and the distribution pattern of caudal papillae in males which includes 5 pairs precloacal, 1 pair adcloacal and 5 pairs postcloacal in position.
