Studies of plant and soil nematodes. 11. Carphodorus biLineatus n.g., n. sp. (Nematoda:Dolichodorinae) from eucalyput forest in Queensland

Abstract

The genus Carphodorus is proposed to accommodate C. bilineatus n.sp., which has a subspherical lip region with internal sclerotization, long stylet, oesophagus with a short terminal lobe overlapping the intestine, hemizonid behind the excretory pore, two ovaries and a subcylindrical tail with a broadly rounded terminus. In 1964 an undescribed species with many of the characters of Dolichodorus Cobb but possessing an oesophagus with a short terminal lobe overlapping the intestine was found in well-drained, sandy soils from eucalypt forests at Pozieres and Landsborough in southern Queensland. Populations were relatively low and males were more common than females.
