Analysis of the morphology of Spinalona anophtalma Ciros-Pérez and Elías-Gutiérrez, 1997 (Aloninae, Anomopoda, Cladocera)
Morphology and variability of Spinalona anophtalma Elías-Gutiérrez & Ciros-Pérez, 1997 were re-examined using material from the original sample from type locality. As a result, some additions were given to the first description, and thoracic limbs were completely redescribed. We revealed and discussed some rare or unique traits of Spinalona, like a peculiar setulation on the labrum, distribution of aesthetascs in the antennular tip, position of the lateral seta on basal segment of endopodite of the second antenna, and the armature of swimming setae, and new structures on thoracic limbs. Although we confirmed previously reported opinion, that Spinalona is the most specific animal among Alonini, it clearly belongs to this taxon. The genus diagnosis was re-worked according to recent standards.
