Abstract
The Neotropical freshwater cladoceran Bergamina lineolata (Sars, 1901) was found in a small temporal pond in the Magdalena department. Hitherto, it has been reported in Brazil and El Salvador. It was originally described as Alonella lineolata by Sars, 1901 from Brazil and then placed to the genus Bergamina by Elmoor-Loureiro et al. (2013). This is the first record of this species in Colombia. B. lineolata can be identified by a unique combination of characters including: 1) a remarkably large and oblong postabdomen, with three denticles on distal corner; 2) basal spine of the claw very short, length less than the half claw diameter at base; 3) IDL with two setae shorter than ODL seta, armed with fine setules unilaterally in terminal half; 4) endite 1 of trunk limb I with a long smooth seta between endites 1 and 2.
Highlights
The Superorder Cladocera is one of the major zooplankton groups in many freshwater bodies (Jeong et al, 2015) and constitutes a vital component in aquatic food web worldwide by transferring energy from the lower to higher trophic levels (Choedchim et al, 2017)
It was originally described as Alonella lineolata by Sars, 1901 from a single female found in aquaria prepared with dried mud from São Paulo, Brazil
2000 Genus Bergamina Bergamina lineolata (Sars, 1901) Material examined: 2 adult females specimens were collected by one of us (JMF-R) from an ephemeral pond located in Magdalena, Colombia (10°27’12.20” N; 74°23’33.2” W) in November 2020 (Figures 1-12)
Summary
The Superorder Cladocera is one of the major zooplankton groups in many freshwater bodies (Jeong et al, 2015) and constitutes a vital component in aquatic food web worldwide by transferring energy from the lower (phytoplankton, bacteria, fungi) to higher trophic levels (Choedchim et al, 2017). Foi originalmente descrito como Alonella lineolata por Sars, 1901 no Brasil, e, em seguida, colocado no gênero Bergamina por Elmoor-Loureiro et al (2013). Bergamina lineolata is considered a rare species (Elmoor-Loureiro et al, 2013).
