Differentiation between african leydigia ciliata Gauthier, 1939 and Neotropical L. cf. striata Birabén, 1939 (Chydoridae, anomopoda, cladocera)
We investigated the morphology and variability of Leydigia ciliata Gauthier, 1939 (Chydoridae, Anomopoda, Cladocera) from Africa and of Leydigia cf. ciliata from the Americas, using optical microscope and SEM. Some differences, predominantly in limb armature, between African and Neotropical populations were revealed. Probably, the name L. striata Birabén, 1939 must be used for Neotropical populations, but this opinion must be confirmed by re-examination of topotypical material (Puerto de La Plata, Argentina). The confused situation in the systematics of the Leydigia acanthocercoides-ciliata complex is confirmed and some characters previously applied to the discrimination of L. ciliata Gauthier, 1939 from L. acanthocercoides (Fischer, 1854), are discussed.
