Studies of plant and soil nematodes. 14. Five new species of Tylenchorhynchus Cobb, ParatyLenchus Micoletzsky, MoruLaimus Sauer and Hemicyctiophora de man (Nematoda:Tylenchoidea)

Abstract

Five new species of TYLENCHOIDEA are described. Tylenchorhynchus dissitus n.sp. has a short cylindrical tail the posterior half of which is expanded cuticle, a conspicuous double epiptygma and smooth rounded lip region. Paratylenchus mutabilis n.sp. has three longitudinal bands of small tubercles in the lateral fields in the swollen portion of the body of mature females and four incisures in the unswollen portion. Morulaimus soldus n.sp. resembles M. arenicolus Sauer but has a subcylindrical tail, shorter stylet and few distinct transverse striae in the outer bands of the lateral fields between oesophagus and anus. Hemicycliophora spinosa n.sp. has two posteriorly-directed spines on the anterior lip of the vulva and peanut-shaped depressions in the lateral fields. Hemicycliophora biloculata n.sp. has a subcylindrical tail and lateral fields marked by two separate rows of square,slightly elevated blocks.
