The mesostigmal complex of Argia using scanning electron microscopy (Zygoptera: Coenagrionidae)

The mesostigmal plates and associated structures (together referred to as the mesostigmal complex) were examined using scanning electron microscopy (SEM)for adult female A. translata, A. tibialis and A. apicalis. Several anatomical features unique to the respective spp. are described in terms of lobe formation, carinae arrangement, and the presence or absence of grooved areas.
