Measurements. See Table 6.

Remarks. Only the J 2 of a Cactodera species was found from a zoysiagrass tee in Moore County, NC, and from a bermudagrass fairway in Florence County, SC. No cysts or white females were detected. The morphological characteristics of the J 2 were similar to those of C. thornei , which was first described from the roots of Miner's lettuce ( Montia perloliata ) in California by Golden & Raski ( 1977). This species has been recorded from China ( Peng & Vovlas 1994). However, the species found here could not be identified since no cysts were collected and DNA sequences for comparison are unavailable. This is the first record of the genus Cactodera from turfgrasses in NC and SC.
