The head anatomy of Epiophlebia superstes (Odonata: Epiophlebiidae)

Original Article

Abstract

The relic dragonfly family Epiophlebiidae is recovered as sistergroup of Anisoptera (= Epiprocta) by most molecular and morphological analyses. However, in a recent study it was placed within Anisoptera as sister group of Cordulegastridae. In another study, several affinities to Zygoptera in the morphology of the ovipositor and the egg-laying behaviour were pointed out. Here, we present a detailed study of the outer, as well as the inner, head morphology of Epiophlebia superstes. Compared with the last detailed literature account, three additional mandibular muscles were discovered, as well as additional buccal and pharyngeal muscles. The results are compared with the anatomic features of Zygoptera and Anisoptera. A formal character evaluation focused on head characters confirms the sistergroup relationship of Epiophlebiidae and Anisoptera.

Fabian Wilde (HZG, Geesthacht), as well as Sebastian Thieß and Wolfgang Drube (DESY, Hamburg), provided excellent support at the DESY synchrotron facilities. The scanning was done in the course of proposals no. I-20080169 and I-20090211. Marco Stampanoni and Peter Modregger are sincerely thanked for their support at the PSI for SLS TOMCAT beamline analysis (proposals 20100137 and 20110069). Irina Ruf (Steinmann Institute, Bonn, Germany) made microCT investigations at the device of the Steinmann Institute possible. We would like to express our gratitude to Professor Ryuichiro Machida (University of Tsukuba, Japan) who kindly provided specimens of E. superstes. Benjamin Wipfler and Rolf Beutel (University of Jena, Germany) are thanked for useful advice. Furthermore, we thank two anonymous reviewers for their valuable comments. The laboratory members of the ZFMK are sincerely thanked for their support.
