Abstract

top
The diploid chromosome number 2 n = 16 has been established in both sexes of the harpacticoid copepod Tisbe biminiensis. The chromosomes are metacentric or sub-metacentric, and differentiated sex chromosomes are not present. Chiasmatic metaphase bivalents occur in the male. In the female, after the diffuse stage the homologues separate but remain juxtaposed to each other till metaphase I. The diploid chromosome numbers so far reported for species of the genus Tisbe are 24. The phylogenetic meaning of the different chromosome numbers in Tisbe is briefly discussed.
