New records of Cladocera (Crustacea: Branchiopoda) from the Tomo River, Vichada, Colombia

Authorship SCIMAGO INSTITUTIONS RANKINGS

Five species of cladocerans are reported from the Tomo River, Vichada, Colombia. Zooplankton samples were collected from the littoral zone with vegetation (Campsiandra comosa Benth). Three of them, namely Streblocerus pygmaeus Sars, 1901, Disparalona cf. hamata (Birge, 1879) and Alona isabellae Sousa, Elmoor-Loureiro and Santos, 2016 are new to the Colombian cladoceran fauna. Descriptive notes, comparative comments on morphology and variability and illustrations are also provided for some remarkable taxa. This is the first report on the cladoceran fauna in the Tomo River.
