Studies of plant and soil nematodes. 12. The eucalypt cystoid nematode Cryphodera eucalypt n.g., n. sp. (Nematoda:Heteroderidae), a parasite of eucalyptus in Queensland

Abstract

A new genus, Cryphodera, is erected and the type species C. eucalypti, a parasite of eucalypts, is described. This genus resembles Meloidodera Chitwood, Hannon and Esser, from which it is distinguished by the more posterior position of the vulva. In 1964, larvae and males of a new species of Heteroderidae were obtained from soil in eucalypt forest at Long Pocket, Brisbane. Females were found partially embedded in small ungalled roots of Eucalyptus major (Maiden) Blakely (a grey gum).
