Studies of plant and soil nematodes. 13. Tylenchulus cLavicaudatus n. sp. (Nematoda:Tylenchulidae), a parasite of the liana Deeringia arborescens (R. Br.) Druce

Abstract

Tylenchulus clavicaudatus n.sp. is described. This species is distinguished from T. semipenetrans Cobb, T. mangenoti Luc, T. obscurus Colbran and T. fioridensis (Raski) by the clavate tail terminus of second-stage larvae. In 1964, larvae and males of the species described in this paper were found in rain-forest soil from Cunningham's Gap National Park in southern Queensland. Examination of plants growing in the area revealed females partially embedded in the smaller roots of the liana Deeringia arborescens (R.Br.) Druce under small scales similar to those associated with Tylenchulus obscurus Colbran (see Colbran 1964, p. 107).
