Summary
InOligarces paradoxus, the chromosomal behaviour was compared during pedogenetic development of ♀♀ and ♂♂. The ♀-egg undergoes a single non-reductional maturation division, the ♂-egg shows two divisions which result in reduced nuclei. After maturation in the ♂-egg, the number of chromosomes is restored by endomitosis. The nuclei of germ-line cells contain a high number of chromosomes (♀: 74\2-82; ♂: at least 58) in both sexes. In somatic nuclei, the number is diminished by elimination to 10 in ♀, to 5 in ♂.
