Morphology and Anatomy:

Laimaphelenchus preissii 1, female; 2, male; 3, spicules; 4, vulval region; 5, lateral field; 6, male tail; 7, female anterior end; 8, female tail. Scale bars = 50 μm, 1, 2, 4 - 8; 25 μm, 3.

From Zhao et al., 2006.

Female:

Anterior lip of vulva forming a flap over the vulva.

Gonad with spermatheca and long postuterine sac containing cells, possibly sperm(?).

Female tail has one broad tubercule with about ten projections.

Distribution:

Described from bark of Callitris preissii, native pine in Australia.

Feeding:

Laimaphelenchus preissii was found in the bark of native pine C. preissii, but not in the wood. It appeared to be feeding on fungi or lichens growing on the bark of the tree.

It was cultured successfully on Botrytis cinerea, Monilinia fructicola and Rhizoctonia solani with the best growth occurred on B. cinerea.

No insects appeared to be associated with it on the host pine trees.
