In populations of pseudoscorpions in fragments of mangrove forest of the department of Córdoba, Colombian, Caribbean, was carried out a study on sex ratio and periods of reproduction. A total of 1,037 individuals were collected, distributed in five families and six species. Most of the species presented a sex ratio 1:1, and periods of reproduction univoltine, however, Epactiochernes sp., it registered a sex ratio slanted toward the females and Serianus aff. carolinensis, present periods bivoltines. The sex ratio exhibited by most of the species and the periods of reproduction, they suggest that its bound selective strategy to the reproduction, is adjusted to the climatic season of the mangrove forests, related with the exclusivity of the species in the microhabitat where they are unwrapped.
