Final instar Nymph of Psilopsocus nebulosus Mockford (Psocoptera: Psilopsocidae), redescribed and compared with two wood-boring Species of the Genus.

Abstract

The nymph of Psilopsocus nebulosus Mockford (from Philippines) is redescribed and compared with that of Ps. mimulus Smithers (from Australia) and an undescribed species of Psilopsocus (from South Africa). The morphological adaptations to the unusual wood-boring habit in these remarkable psocopterans are discussed.
