"The 2 pinworms parasitic in man are studied and compared. E. vermicularis (L., 1758) has the larger spicule (100-140 .mu.m). E. gregorii Hugot, 1983 has the shorter spicule (70-80 .mu.m). The 2 spp. can also be differentiated by the cuticular ornamentation associated to the cloacal opening in the males." . . "Hugot & Tourte-Schaefer (1985)" . "Hugot, J. & Tourte-Schaefer, C. 1985.
