Abstract
The diploid chromosome number of Nala lividipes is 40 with an XY sex-mechanism, the highest number thus far reported in Dermaptera. Meiosis is orthodox and typically dermapteran. The X and Y chromosomes are derived from a single positively heteropycnotic body found in the interphase of the primary spermatocyte. First division is reductional and the second division is equational for sex chromosomes. Evolution of chromosome number and the sex mechanism in the dermaptera are discussed.
