Abstract

The results of manual dissection of the musculature of the male genitalia in Nothybuskuznetsovorum are fully confirmed by the modern methods of Micro-CT. A comparative analysis of Neriacommutata and Cothornobata sp. shows that an increase in the flexion in the genitalia of males and the displacement of syntergosternite VII to the ventral side in Cothornobata sp. caused the disappearance of the muscles ITM6–7r and ITM7–8r. In addition, this increase in flexion apparently caused the fusion of the M18 muscles into one bundle. The muscle ISM5-6c goes on to moving the second segment of the forcipate appendages of sternite V.
