dc.description.abstractSteinernema texanum n. sp. is characterised by morphometrics of the infective juvenile with body length = 756 mu m, distance from anterior end to the excretory pore = 59 mu m, tail = 73 mu m, ratio a = 25, H% = 59 and E% = 81. The lateral field pattern of the new species is 2, 7, 2, and is typical for the species. The male of the first generation can be recognised by the spicule and the gubernaculum lengths and shapes, position of the excretory pore, D% = 67 and GS% = 75. The female can be recognised by the vulva with very low epiptygma and two wart-like structures anterior to the tail tip that are always present on the ventral side. Steinernema texanum n. sp. is characterised genetically by the sequence of the ITS region (sequence length = 956 bp, the length of ITS I = 263 bp, ITS2 = 286 bp, composition of its sequence and by 18 autapomorphies) and by sequence of D2D3 regions (sequence length = 860 bp, its composition and 15 autapomorphies). Steinernema texanum n. sp. is closely related to species in the feltiae-group, which include S. akhursti, S. feltiae, S. hebeiense, S. jollieti, S. kraussei, S. kushidai, S. litorale, S. monticolum, S. oregonense, S. sangi, S. silvaticum and S. weiseri. Isolates of the new species were obtained using the Galleria-baiting technique from soil samples taken near Kingsville, Texas, USA.
