Two species in the genus Hemicriconcmoides, H.wessoni and H.chitwoodi, were recovered from soil samples collected from turfgrasses in North and South Carolina, USA during 2011 and from previous collections.They are morphologically differentiated from each other by the number of body and sheath annuli (111-124 in H.chitwoodi vs 83-95 in H.wessoni), stylet length (80.0 ~ 93.0μm in H.chitwoodi vs 48.0 ~ 58.5μm in H.wessoni), vulval sheath (absent in H.chitwoodi vs present in H.wessoni), vulval position (at 12 ~ 17th annulus from posterior end of the body, located at 90.0% ~ 91.7% of the entire body in H.chitwoodi vs at the 7 ~ 10th annulus, located at 91.2% ~94.9%) and tail shape (conoid, tapering to an angular tip in H.chitwoodi vs narrows abruptly after anus,possessing a big and wide sheath at the tail in H.wessoni).The morphological and morphometric characteristics of these species are presented.
