of the larval development of Imnadia yeyetta and Leptestheria
dahalacensis (Branchiopoda: Conchostraca)
486: 39-47 (2002), with kind permission from Kluwer
paper presents a SEM documentation of the larval development of the
two most abundant Austrian conchostracan species, Imnadia yeyetta
(Limnadiidae) and Leptestheria dahalacensis (Leptestheriidae).
As in several previously examined spinicaudatan species, five larval
stages were documented: Nauplius 1, Nauplius 2, Metanauplius, Peltatulus,
and Heilophore. Additionally, three postlarval stages of L. dahalacensis
and the first larval instars of Eoleptestheria ticinensis and
Limnadia lenticularis are shown and compared with the examined
stages. Species identification of conchostracan larval stages is possible
by using surface structures, and using SEM methods, except for L.
lenticularis which can be identified more easily on the characteristic
shape of the labrum.
