Pellamigralus annularis sp.n. and Dolichorhynchus parvus sp.n. from Chile and Helicotylenchus angularis sp.n. from Belize have been described and illustrated. P. annulalus is similar to P. longistylus and P. perscitus in having distinctly annulated lip region and areolated lateral fields at the phasmids, but differs from them in having a smaller body and shorter spear. Helicotylenchus angularis is unique in the genus in having an angular lip region. Dolichorhynchus parvus is the smallest species of the genus.
