Abstract
Spermatogenesis was examined in Panorpa anomala, P. acuta, Bittacus pilicornis and B. stigmaterus. Both species of Panorpa were found to be achiasmate and had a chromosome number of n = 22 + X(O). The behavior of the sex bivalent and frequency of end-to-end association among non-homologous chromosomes is discussed for the Panorpa species Bittacus pilicornis (n = 14 + X[O]) and B. stigmaterus (n = 15 + X [O]) had chiasmate meiosisKeywords
