Abstract
Within the order Phasmatodea there is a basic egg capsule morphology w hich defines the order. This shows extensive variation in detailed for m. Some of this is aberration, which can be recognised and excluded fr om taxonomic considerations. Much is adaptation to egg-laying techniqu es and egg survival. Nevertheless the range of egg capsule form both e xternally and internally is a valuable aid to the classification at su b-ordinal level and below of this group of insects. In particular this confirms the Timematodea as members of the or der, confirms the disti nct status of Phylliidae and shows some so far undivided groups such a s Necrosciidae to be taxonomically very diverse. A new tribe Extatosom atini is proposed for Extatosoma Gray on the basis of both egg and adu lt morphology. A survey of internal micropylar plate types within the order is given.
