SCANNING ELECTRON MICROGRAPHY OF SOME TYLENCHIDAE AND BOLEODORIDAE AND REAPPRAISAL OF THE BOLEODORIDAE BY M. W. BRZESKI1) and M. R. SAUER2) 1) Instytut Warzywnictwa, 96-100 Skierniewice, Poland, and 2) CSIRO Division of Hor- ticultural Research, Merbein, 3505, Australia Ten species of Tylenchidae and three species of Boleodoridae were examined in SEM and divided into three groups. The first one consists of Tylenchus davainei, Filenchus thornei, Irantylenchus vicinus, Tylenchus ditissimus and Lelenchus leptosoma. These are characterised by small pits near oral opening, no offset disc, four incisures in the lateral field (except L. leptosoma), wide vulva, and presence of hypoptygmata. Ottolenchus facultativus is similar to these species. The second group in- cludes Aglenchus agricola, Coslenchus costatus and C. alacinatus. The oral opening in these is also sur- rounded by small pits which, together with amphidial apertures, are located on an offset disc; lateral field formed by distinct ridges, vulva small and located in a vulval cavity, hypoptygmata present. Cephalenchus emarginatus is close to this group. The third group includes Basiria gracilis, Neopsilenchus magnidens and Boleodorus thylactus. In these the oral opening is surrounded by six larger papillae, a second circle of cephalic sensory organs is formed by four sublateral
