Table 4 Placement of epandrial lobes, mating position and visibility of oviscapt valves in SEM-analysis of D. pachea mating couples

From: Drosophila pachea asymmetric lobes are part of a grasping device and stabilize one-sided mating

Treatment Total number of mating couples Number of mating couples with both lobes in ‘wild-type position’ Number of mating couples with abnormal left lobe position Number of mating couples with abnormal right lobe position Number of mating couples with abnormal position of both lobes Microscale angle of male relative to female (degrees; mean ± SD) Number of mating couples in which oviscapt valves were visible
Unmodified wild-type 14 14 0 0 0 6.09 ± 4.40+ 14
Symmetric mutant 16 6 6 3 1 9.77 ± 12.36 9
Left lobe cut 14 3 8 2 1 16.68 ± 10.45*+ 7
Right lobe cut 10 5 0 4 1 1.15 ± 18.77 8
Left lobe shaved 4 3 1 0 0 10.68 ± 14.00 3
Right lobe shaved 8 3 0 3 2 1.39 ± 16.38* 6
  1. The microscale angle of the male epandrium relative to the female abdomen was measured from the ventral side (Fig. 10); values denoted by * are significantly different from each other at α = 0.05, as are values denoted by +
