Alonella is a genus of Chydoridae.
The genus was described in 1862 by Michael Sars.
It has cosmopolitan distribution. The results of genetics analysis revealed at least twelve divergent phylogenetic lineages, possible cryptic species, of Alonella, with different distribution patterns. As expected, the potential species diversity of this genus is significantly higher than traditionally accepted.
