Two new records of dorylaimid nematode (Nematoda: Dorylaimida) from India

Promumtazium pyxidorum Siddiqi, 1982 and Nygolaimus brachyuris (De Man, 1880) Thorne, 1930 have been reported for the first time from India. Promumtazium pyxidorum Siddiqi, 1982 have been observed both from the forest ecosystem of Bharatipura Hills, Keonjhar district, Odisha and Ramnabagan WLS, commonly known as Bardhaman Zoological Garden, Bardhaman district, West Bengal. Nygolaimus brachyuris (De Man, 1880) Thorne, 1930 has been reported from the island ecosystem of Hope Island, Coringa WLS, East Godavari dist, Andhra Pradesh. Soil samples have been processed following standard methods of Cobbs Sieving and Decantation method and modified Baerman funnel technique to extract the nematode specimens. Promumtazium pyxidorum was first described by Siddiqi in 1982 from the Colombian rainforest, and its distribution was later reported in Japan and South Korea. On the other hand, Nygolaimus brachyuris was first described as Dorylaimus brachyuris by De Man in 1880, based on specimens from the Netherlands and Norway. It was later transferred to the genus Nygolaimus by Thorne in 1930, with reports from Salem, Utah, with wide distribution in world. Promumtazium pyxidorum is characterized by a didelphic female genital system, a short, rounded tail, a fusiform odontostyle, and a distinctly sclerotized tip of the lip region. Nygolaimus brachyuris is characterized by comparatively feeble spear as long as width of lip region with rectum and prerectum somewhat longer than anal body diameter.
