EC24DE25FFFC996BFF392E43FAF950DB.taxon	diagnosis	Diagnosis and relationships: Mesodorylaimus bomdillaensis n. sp. is characterized by having 0.73 – 0.81 mm long body; lip region offset by slight depression, ‘ double’ guiding ring; stirrup-shaped amphid; 10 µm long odontostyle; pharyngeal expansion gradual; amphidelphic female genital system; transverse vulva; tongue-like structure at intestine-prerectum junction and tail long filiform with pointed terminus. In the presence of long filliform tail and small body size, the new species comes close to M. chamoliensis Ahmad, 1995; M. pusillus (Cobb, 1893) Andrássy, 1959; M. longicaudatus Ahmad and Araki, 2003; and M. loofi Ahmad, 1993 but differs from the former in having ‘ double’ guiding ring (vs single); rounded lip region (vs flat lip region); longer and differently shaped cardia (vs short conoid to hemishpherical, 10 – 18 µm); tongue-like structure present at the intestine-prerectum junction (vs tongue-like structure absent). From M. pusillus, the new species differs in having ‘ double’ guiding ring (vs single); shorter odontostyle (vs twice lip region widths long); pharyngeal expansion gradual (vs sudden); slightly shorter prerectum (vs more than twice anal body widths long), and longer tail (vs c = 5.6 – 6.7, c’ = 9 – 11). It differs from M. longicaudatus, in having smaller and robust body (vs L = 1.13 – 1.36 mm, a = 40 – 49); shorter odontostyle and odontophore (vs odontostyle 12 – 13 µm, odontophore 14 – 15 µm); ‘ double’ guiding ring (vs single); smaller expanded part of pharynx (vs pharynx 98 – 111 µm), longer and differently shaped cardia (vs hemispheroid, 9 – 12 µm), shorter prerectum (vs 38 – 56 µm); tongue-like structure present in intestine-prerectum junction (vs absent); smaller tail (vs tail 264 – 316 µm long, c’ = 14.8 – 16.5) and without distinct hyaline part in tail (vs hyaline part 42 – 43 %). From M. loofi, the new species differs in having; smaller body (vs L = 1.2 – 1.5 mm); lip region offset by slight depression (vs lip region almost continuous), shorter odontostyle and odontophore (vs odontostyle 13 – 14 µm; odontophore 16 – 21 µm); smaller pharynx (vs 263 – 290 µm); tongue-like structure present at intestineprerectum junction (vs absent); smaller tail (vs c = 4.9 – 6.7; c’ = 10 – 13.8) and absence of male (vs present).	en	Tauheed, Uzma, Ahmad, Wasim (2010): Four new species of the genus Mesodorylaimus Andrássy, 1959 (Nematoda: Dorylaimida) from India.
