The new species has been named after the eminent nematologist Dr. István Andrássy.	en	Sen, Debabrata, Chatterjee, Amalendu, Manna, Buddhadeb (2012): One new and two known species of Dorylaimoidea (Nematoda) from West Bengal, India.

CD3587A3FFD6AF09FF7B11A0FC91FB09.taxon	diagnosis	Diagnosis and relationships. Laimydorus istvani sp. n. is characterized by its medium body length (L = 2.5 – 2.9 mm), slender body evident from a value (a = 39 – 46), shorter tail (213 – 323 µ m) in relation to body length evident from c - value (c = 9.0 – 13.4), odontostyle being distinctly thicker than the cuticle at the same level and by the shape of cardia (cardia rounded-conoid, sometimes wide at pharyngo-intestinal junction, enveloped by intestinal tissue which forms a conical projection extending into the lumen of intestine; a delicate ring-like structure surrounding the junction between the pharyngeal base and the proper cardia).	en	Sen, Debabrata, Chatterjee, Amalendu, Manna, Buddhadeb (2012): One new and two known species of Dorylaimoidea (Nematoda) from West Bengal, India.

CD3587A3FFD6AF09FF7B11A0FC91FB09.taxon	discussion	Discussion. Khera (1970) described the new species Dorylaimus multialaeus from Lucknow, India. Baqri (1985) re-studied the specimens and re-designated the specimens as Laimydorus multialaeus, a new combination, due to the absence of cuticular longitudinal ridges (the presence of longitudinal ridges on the cuticle is characteristic of the genus Dorylaimus and some other members of the subfamily Dorylaiminae). Jairajpuri and Ahmad (1992) included the species under the genus Dorylaimus but Andrássy (1988) again placed it under Laimydorus supporting the view of Baqri (1985). The present new species of Laimydorus has been compared with L. multialaeus because of their morphological similarities.	en	Sen, Debabrata, Chatterjee, Amalendu, Manna, Buddhadeb (2012): One new and two known species of Dorylaimoidea (Nematoda) from West Bengal, India.

CD3587A3FFD2AF0BFF7B17E5FB46F877.taxon	discussion	Remark. The present specimens agree well with the type specimens described by Baqri and Jana (1982) from soil around the roots of paddy rice (Oryza sativa) at Coochbehar district, West Bengal except for some variations in lengths of body, odontophore, prerectum and tail (L = 2.11 – 2.44 mm, odontophore = 29 – 30 Μm, rectum = 40 – 45 Μm and tail length = 190 – 224 Μm in type specimens). In the single male paratype treated in the original description, the body length was reported as 1.83 mm, slightly shorter than in the present specimens. Other characters, such as odontostyle, spicule and prerectum lengths, and the number of ventromedian supplements fit the ranges of the studied material (odontostyle 24 Μm, spicules 53 Μm and prerectum 236 Μm, 24 contiguous supplements preceded by an adanal pair). Bohra and Baqri (2004) and Bohra et al. (2005) reported this species from different localities of Gujarat state, India.

CD3587A3FFDFAF06FF7B1386FEBFFC14.taxon	discussion	Remarks. Baqri and Jana (1986) described Dorylaimus geraerti from the soil around roots of brinjal (Solanum nigrum L.) from Narendrapur, South 24 - Parganas, near the collection site for these specimens, within the same block. The present specimens fit well with the type specimens of D. geraerti except for the b value (4.2 – 5.1 vs. 4.3 – 4.7), length of odontostyle, odontophore, prerectum and tail length in females (33 – 42 vs. 43 – 47 Μm, 33 – 49 Μm vs. 40 – 43 Μm, 120 – 160 vs. 196 – 241 Μm, 247.5 – 294 Μm vs. 249 – 406 Μm in females, respectively). Although Dorylaimus sp. differs from Dorylaimus geraerti in odontostyle and odontophore length, the odontostyle-lip region ratio (2 – 2.8 vs. 2.4 – 2.6) and odontophore-odontostyle ratio (0.8 – 1 vs. 0.9 – 1) are almost in the same ranges. In the male paratypes of D. geraerti, there are 35 – 38 supplements, mostly contiguous, but with 4 – 5 spaced supplements in the middle of the series. Baqri and Jana (1986) concluded that D. geraerti is similar to the genus Ischiodorylaimus Andrássy, 1969 in having sets of both contiguous and a few spaced supplements, but they placed it under the genus Dorylaimus Dujardin, 1845 due to its shorter body and the ventromedian supplements not being arranged in two distinct groups. The present male specimen differs in arrangement of ventromedian supplements in having the contiguous supplements without any spaced ones but the number of supplements is within the range of D. geraerti. In spite of resemblance and closeness with D. geraerti, the present specimens are designated as Dorylaimus sp. without creating a new species until and unless more male specimens are available and can be examined.	en	Sen, Debabrata, Chatterjee, Amalendu, Manna, Buddhadeb (2012): One new and two known species of Dorylaimoidea (Nematoda) from West Bengal, India.
