Sexual dimorphism in wing cell patterns in Xanthocnemis zealandica McLachlan (Zygoptera: Coenagrionidae)

In many odon. spp. 3 3 and $ ? differ phenotypically; the most commonly noticed characters which exhibit sexual dimorphism are size, and body- and wing colouration. Although the odon. wing venation has been studied intensively, very limited data on sexual dimorphism exist. In this study distinct cell groups in the wings of X. zealandica were compared between 3 3 and S $. Of the 6 cell groups studied two were sexually dimorphic. Reasons for the observed differences are discussed.
