The capitula of phasmid eggs: an update with a review of the current state of phasmid ootaxonomy

The relationship between egg shape and presence or absence of a capitulum is considered. The distribution of capitula of different types within the order Phasmida is reviewed. These tend to confirm tribal and subfamily groupings but suggest that the suborder Anareolatae is polyphyletic and some suggestions are made for its regrouping. The species of Phasmida which have been recently studied from an ootaxonomic viewpoint are surveyed.
