A note on Pseudevadne tergestina claus, 1877 (Branchiopoda: cladocera: onychopoda) of Banco Chinchorro, with observations on its biology
Zooplankton samples from Banco Chinchorro cointaned individuals of the marine cladoceran Pseudevadne tergestina. Samples were taken from the surface layer (1-2 m) during few days in 2-3 September, 1999 and 28-29 March, 2000. This species was present only in September in the sampling stations outside the atoll with a maximum density of 0.6 ind m−³. The species was not recorded inside the atoll. Parthenogenetic females carried from 1-5 embryos in the brood pouch. All the developing stages were represented (I-VI). The most frequent stage was IIIB followed by IIIC. The size of the animals captured ranged from 550-830 mm.
