Abstract

In the present manuscript, a new species Talanema dhritiae sp. n., collected from vineyard in Chhatna village of Bankura district, West Bengal, India is described based on characters: having shorter body (L=0.71-0.97 mm), a=15.5-20.5, b=3.4-4.6, c=28.4-35.4, c’=0.9-1.1, V=44.6-48.2, transverse vulva, small spherical cardia and digitate tail. It shows similarities with T. avolai (L=0.85-0.99 mm) and T. salinae (L=0.7-0.8 mm) in having small slender body, but differs from both of them in odontostylet length (15.7-17 µm in T. avolai and 12-14 µm in T. salinae), width of lip (11-14 µm in T. avolai and 12-14 µm in T. salinae), oesophageal length (251-263 µm in T. avolai and 210-243 µm in T. salinae) and position of vulva (V=55.3-61.3 in T. avolai and 56.8-58.4 in T. salinae ), pre-rectum length (52-58 µm in T. avolai and 23-39 µm in T. salinae) and shape of cardia (spherical vs conical). The species key of the genus is also provided.
