Scutellonema bizanae is reported for the first time in Brazil. Measurements of male and female specimens are presented and briefly discussed. Neodolichodorus rostrulatus, originally described from a single female collected in the state of Bahia, is recorded for the second time in Brazil, from soil collected at Cananeia, state of Sao Paulo. The variabilility observed on morphological (tail shape of the juvenile stages in particular) and morphometrical (body length, stylet length, distance from anterior end to the pharyngo-intestinal junction, distance from anterior data to the excretory pore, length of spicules and gubernaculum) data among populations from Brazil, Costa Rica, and Senegal are discussed. It is suggested that N. rostrulatus may represent a species complex.
