Abstract

<i>Enalikter aphson</i> is an arthropod: a reply to Struck <i>et al</i> . (2014)

Highlights

The absence of tergopleurae noted by Struck et al [1] was noted by us [5]; these structures are lacking in some other arthropods, including Bundenbachiellus giganteus, which all agree is an arthropod
In contrast to Struck et al [1], that a discrete, dorsal, cap-like cover is present on the head of Enalikter, which represents an arthropod head & 2015 The Authors
Distinct head appendages are present in all arthropod crown groups, where this is often a defining feature

Summary

Introduction

The absence of tergopleurae noted by Struck et al [1] was noted by us [5]; these structures are lacking in some other arthropods, including Bundenbachiellus giganteus, which all agree is an arthropod. The clear difference between the morphology of the anterior appendages and those of the trunk of Enalikter, which Struck et al [1] contend supports an annelid affinity, could well be used to support an arthropod affinity. Distinct head appendages are present in all arthropod crown groups, where this is often a defining feature.
