Chromosomes and meiosis in two species of Dermaptera.
The chromosome cytology of two species of Dermaptera, namely Diplatys gladiator and Forficula sp., has been studied. The diploid number of chromosomes in male Diplatys gladiator is 18 (16AA + XY), whereas in male Forficula sp. it is 27 (24AA + X1X2Y). These are the two new chromosome numbers for Dermaptera. The evolutionary status of Forficula sp. in the family Forficulinae has been emphasized.
