Remarks. Scutellonema brachyurum was described from red spiderlily ( Lycoris radiata ) in Hamlet, Richmond County, NC, and was also documented in SC ( Kraus-Schmidt & Lewis 1979). CABI (2006) recorded S. brachyurum in six countries in Europe, 11 in Asia, 15 in Africa, two in North America ( Canada, USA including Arkansas, California, Florida, NC, SC), four in Central America and the Caribbean, four in South America, and five in Oceania. A series of studies on the host range of S. brachyurum in South Africa was carried out from 1988 to 2001 ( Waele & Jordaan 1988a; 1988b; Bolton et al. 1989; Jordaan et al. 1992; Venter et al. 1992; Fourie et al. 2001). Tarjan (1964a) reported it on bermudagrass in Egypt. Agudelo & Harshman (2011) first found it on lilyturf ( Liriope muscari ) in SC. In the present study, S. brachyurum was found only in Beaufort County, SC, in samples from a bermudagrass putting green. The morphology and morphometrics of the identified population did not differ from other populations ( Siddiqi 1974b).
