A new and phylogenetically suggestive morphotype of Keratella lenzi (Rotifer, Monogononta), from Argentina

The morphological characteristics of Keratella lenzi (f. ayui) f. nov. and the phylogenetic and ecological implications of the appearance of posterolateral spines in K. lenzi Hauer, 1953 are discussed. The morphotype is described after detailed observations using light and scanning electron microsco...

Description
Summary:The morphological characteristics of Keratella lenzi (f. ayui) f. nov. and the phylogenetic and ecological implications of the appearance of posterolateral spines in K. lenzi Hauer, 1953 are discussed. The morphotype is described after detailed observations using light and scanning electron microscopy, and compared with other Keratella species of the superspecies "valga". The pores of the lateral antennae are described, and proposed as a new character for future comparative research. Some ecological information is also given.
