(Drawings from Van den Berg et al., 2017)
Species of Scutellonema are widely distributed in tropical and subtropical regions with the greatest number of species recorded from Africa (van den Berg et al., 2017); approximately 60% of described species are from that continent..
D-rated pests in California.
Three species, the yam nematode S. bradys, S. cavenessi, and the Carolina spiral nematode S. brachyurum are reported as agricultural pests. Other species are parasites of non-agricultural plants or are unknown to cause economic damage to crops (Van den Berg et al., 2017).
