NAUPLIAR DEVELOPMENT OF ACANTHODIAPTOMUS-DENTICORNIS (WIERZEJSKI, 1887) AND ARCTODIAPTOMUS-ALPINUS (IMHOF, 1885) (COPEPODA, CALANOIDA) AND A COMPARISON WITH OTHER DIAPTOMIDAE
Cd. Jersabek et al., NAUPLIAR DEVELOPMENT OF ACANTHODIAPTOMUS-DENTICORNIS (WIERZEJSKI, 1887) AND ARCTODIAPTOMUS-ALPINUS (IMHOF, 1885) (COPEPODA, CALANOIDA) AND A COMPARISON WITH OTHER DIAPTOMIDAE, Journal of plankton research, 18(11), 1996, pp. 2027-2061
The six naupliar instars of the two alpine species Acanthodiaptomus de
nticornis and Arctodiaptomus alpinus are described and illustrated. Th
eir external morphology is compared with that of all presently known d
iaptomid nauplii in an attempt to provide useful taxonomic characteris
tics to identify larval diaptomids. The larval stages of the two speci
es are remarkably similar in size and overall appearance, and show an
identical pattern of limb setation throughout the whole development. D
iagnostic characters are mainly related to the differentiation of ante
nnules and caudal armature.
