Description of Tobriloides sinensis sp. n. (Nematoda: Triplonchida: Tobrilidae) from Shanxi province, north China

Tobriloides sinensis sp. n. is described from Shanxi province, China. It is characterised by relatively long body (16201935 m), two subventral teeth posterior to dorsal tooth, a short pharynx (b = 4.2-5.0), cardia three times longer than wide (91-98 mu m long and 30-37 mu m wide), female reproductive system amphidelphic, the vulva situated slightly posterior to mid-body (V = 59.0-69.9), and the tail relatively short (c = 8.4-9.7 and c' = 4.6-5.7). The phylogenetic relationships of the new species were analysed using data from the near full length small subunit (SSU) and D2-D3 segments of large subunit (LSU) of rRNA genes. The status of T. sinensis sp. n. is discussed based on both morphological and molecular characteristics.
