Two New Species of the Genus Labronema Thorne, 1939 (Nematoda:Dorylaimida) from West Bengal, India

The genus Labronema was erected by Thorne (1939). It belongs to the family Qudsianematidae under the order Dorylaimida. Andrassy (1991) compared and provided a key to species of the genus, described and reported before 1989-90 (29 species). Jairajpuri and Ahmad (1992) listed 36 species under this genus. Andrassy (2011) made short comments on the nominal species of Labronema, described after 1989-90 (20 species). He opined that out of the twenty species, described under this genus in the last two decades, eleven belong in all probability to the genus, but eight certainly do not. During a taxonomic survey in different districts of North 24 Parganas, West Bengal, India during March, 2005 to February, 2007 nematode specimens belonging to the genus Labronema were collected and identified. They are considered to represent two new species, which are described and illustrated herein.
