Nota sôbre o comportamento do heterocromossômio em Leptysma (Acrididae)

Abstract

Studying the spermatogenesis of Leptysma sp. and Leptysma dorsalis, the writer was able to observe primary spermatocytes in anaphase with the heterochromosome in precession, synchronism or succession, confirming in this way what was observed by Prof. Piza in several other species of Orthoptera.
