SOME SPECIES OF TYLENCHIDA (NEMATODA) FROM PAPUA NEW GUINEA

Eight species of Tylenchida are recorded from Papua New Guinea. A detailed study of Sakia indica supported the inclusion of the genus Sakia in the family Tylenchidae, subfamily Tylenchinae: SEM showed a wedge-shaped labial area not found in any other tylench but reminiscent of what has been found in Filenchus. SEM of Filenchus discrepans was similar to that already reported. Morpho-anatomical observations on six other species of Tylenchida frequently detected in Papua are provided.
