Abstract:
The reports of testate amoebae species in Colombia are limited to a few studies in lentic and peat bog systems; however, the diversity in lotic systems has been poorly investigated. Zooplankton sampling was performed in lotic environments of the Piedemonte Llanero in Colombia. Ten individuals of the species Arcella gandalfi were identified to document the first record of A. gandalfi from the Piedemonte Llanero in Colombia, expanding its distribution from Brazil to Colombia. This finding corroborates the status of A. gandalfi as a flagship species from the South America continent.
