Observation on Campydora (Nematoda: Dorylaimida)

The above indicates the confusion concerning the various morphological features of Campydora, especially with regard to its feeding apparatus, oesophagus and reproductive organs. In 1964, I found some specimens of Campydora demonstrans in soil samples collected in Kashmir, India but did not describe or illustrate the species at that time because the specimens appeared to be very similar to those described by Thorne (1939). During the last few years, I have found more specimens of this species from various other places in the Himalayan mountains. I have never found any specimen of this genus from the plains although I have examined several thousand soil samples from many different localities in India during the last twenty years. This confirms that Campydora prefers a colder climate in India, but according to Nesterov (1979) it is a warm loving species with preference for moist and light soils in Moldavia, USSR. With the specimens collected in India and some received from the U. S. Department of Agriculture through the courtsey of Dr. A. Morgan Golden, it has been possible for me to study the morphology and systematic position of C. demons trans in detail.
