| Abstract: | The six naupliar instars of the two alpine species Aconthodiaptornusdenticornis and Arctodiaptomus alpinus are described and illustrated.Their external morphology is compared with that of all presentlyknown diaptomid nauplii in an attempt to provide usehl taxonomiccharacteristics to identify larval diaptomids. The larval stagesof the two species are remarkably similar in size and overallappearance, and show an identical pattern of limb setation throughoutthe whole development. Diagnostic characters are mainly relatedto the differentiation of antennules and caudal armature. |
