Quercorhabditis rajouriensis gen. n., sp. n.

Etymology. The genus name is derived from the name of host plant, oak ( Quercus leucotrichophora L.).

Relationships. The new genus resembles Diploscapteriodes Rahm, 1928 in the shape of the cheilostom, presence of amphidelphic gonads, leptoderan bursa and long conoid tail. However, it can be differentiated from that genus in having a labial region set off by constriction and wider than adjoining body, heavily sclerotized cheilostom, absence of a ridge-like tooth in the gymnostom, spicules with a free dorsal arm, a somewhat boatshaped gubernaculum and in having ten pairs of bursal papillae (labial region sharply offset, cheilostom not strongly sclerotized, ridge-like tooth present in gymnostom, spicules without dorsal arm, gubernaculum simple and nine pairs of bursal papillae, all lying post -cloacal in Diploscapteroides ). The new genus also resembles Curviditis (Dougherty, 1953) Andrássy, 1983 , Rhabditella (Cobb, 1929) Chitwood, 1933 and Metarhabditis Tahseen et. al., 2004 in having spicules with free dorsal arm. However, it can be differentiated from these related genera in having heavily sclerotized cheilostom with arched rhabdions, hardly differentiable stegostom (cheilostom not cuticularised, arched rhabdions absent and stegostom well developed in Curviditis , Rhabditella and Metarhabditis ). The new genus can further be differentiated from Curviditis and Rhabditella in having well developed bursa (bursa rudimentary in Curvidits and Rhabditella ) and from Metarhabditis in having leptoderan bursa with ten pairs of bursal papillae arranged in 3+4+3 arrangement (bursa pseudopeloderan with eight pairs of bursal papillae arranged in 1+1+1+3+2 arrangement in Metarhabditis ).
