Meteterakis asansolensis sp. nov. (Nematoda: Heterakidae) in Duttaphrynus melanostictus (Schneider, 1899) (Amphibia: Anura: Bufonidae) from Asansol coalfield area, Paschim Bardhaman, West Bengal, India

Abstract

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.

“…Parasitic nematodes are one of the most important group of animals that parasitized different plants and animals. With respect to the knowledge of nematode parasites in India, studies on this group in West Bengal are rather satisfactory (Sou 2019;Sou et al 2019). It should be noted that some reports are available about nematodes reported from Varanus lizards from different parts of India.…”
