During a faunal survey from March 2004 to February 2006 in 29 blocks of Paschim Medinipur district of West Bengal, India, 46 species of soil and plant parasitic nematodes, associated with banana (Musa paradisiaca L. cv. Kanthali) plantations were recorded. Amongst 46 species, 29 belong to the order Dorylaimida and 17 species are under the order Tylenchida. The species are categorized into five different trophic groups viz., plant feeders, bacteria feeders, hyphal feeders, predators and omnivores. The number of plant feeders was maximum (17 species), followed by omnivores (16 spp.), predators (8 spp.), bacteria feeders (3 spp.) and hyphal feeders (2 spp.). Present study indicates that phytophagous nematodes dominated other trophic groups of nematodes in banana plantations in Paschim Medinipur district of West Bengal. © International Society for Tropical Ecology.

Varotylus jairajpurii found in Paschim Medinipur, West Bengal, India is distinguished from all species of Varotylus in general and its closest ally V. siddiqii Mulk and Jairajpuri and V. secondus Mulk and Jairajpuri in particular on the basis of small spirally curved body, high hemispherical lip with distinct annulations which is continuous with body and flat at apex, long stylet, excretory pore near oesophago-intestinal junction and cylindrical tail with broadly rounded striated terminus. A key to all twelve world species of Varotylus is presented here including the new species. Copyright 2011 Zoological Society of Pakistan. Source

Makatinus siddiqii described from Paschim Medinipur, West Bengal, India is distinguished from all species of Makatinus in general and its closest ally M. punctatus Heyns in particular on the basis of short and comparatively robust body, robust odontostyle with aperture of about one-half length, a thin cardiac disc, short tongue-shaped cardia and in the absence of male. A key to all ten world species of Makatinus is presented here including new species, which appears to be the second record of the genus Makatinus from India in the existing literature.

A new predatory nematode species, Actus shamimi n. sp., is described and illustrated. Actus shamimi n. sp. is characterised by medium body length, buccal cavity barrel-shaped with apex of dorsal tooth located at ca 80% from base of cavity and 3-6 subventral denticles present in each latero-subventral row, cardia triangular in shape, amphidelphic gonad with longer oviduct, vagina very short and with distinct pars refringens vaginae containing cuboidal sclerotised pieces, tail elongate-conoid, slightly arcuate ventrally with three caudal glands and prominent terminal spinneret opening. It is similar to A. baqrus but has a smaller body length; absence of advulval papillae and shorter tail. It also differs from A. neocaledonensis in the position of the dorsal tooth apex, length of tail and presence of caudal glands and spinneret. The new species also differs from A. conoidus in the larger buccal cavity; lower lip height; lower c′ value and in having a sphincter at the oviduct-uterus junction; and from A. minutus and A. salvadoricus by longer body, longer buccal cavity, presence of a much more anteriorly located dorsal tooth and much higher c value. The genus Actus is reported for the first time from the Andaman and Nicobar Islands, India. A key to species in the genus is provided. © 2010 BRILL. Source

We recorded 46 species of soil and plant parasitic nematodes belonging to the Orders Dorylaimida and Tylenchida from rhizospheric soil and roots of banana plantations in Paschim Medinipur district, West Bengal from March 2004 to February 2006. Dorylaimida is represented by 29 species under 21 genera of 8 families; 8 species are new to science. Tylenchida is represented by 17 species belonging to 11 genera under 7 famines; 4 species are new to science. Among the 46 species, 15 species (13 dorylaimids and 2 tylenchids) were reported for the first time from West Bengal and 5 species (3 dorylaimids and 2 tylenchids) for the first time from India. Sixteen species (12 dorylaimids and 4 tylenchids) were recorded for the first time from the rhizosphere of banana. Source
