The diploid number of chromosomes in Gonoplectus malayus and Phyllogonostreptus nigrolabiatus (Diplopoda: Myriapoda) is 15 and 24, respectively, with male heterogamety. Whereas the former shows XO-, the latter reveals XXO-type of sexdetermining mechanism. During meiosis, the sex-chromosome(s), move synchronously in Gonoplectus malayus and asynchronously in Phyllogonostreptus nigrolabiatus. The first meiotic division is reductional both for the autosomes and sex-chromosome (s). Deviations in the diploid and haploid number of chromosomes have been observed in both the species.
