Fig.322: Left complex, evolution of main sclerites. - Only the sclerites of the left complex are shown 

 - largely in their natural arrangement. Dorsal views. Species with "S" behind their names have side- 

 reversed phallomeres, and a mirror-image of the original preparation is shown. The branching black 

 hnes represent the assumed phylogeny. The ground-plan is in some respects unclear (? in fig. 322a, 

 discussions in 6.3.1., 6.4., 6.5.): Presence or absence of sclerites L3 and L5; connection or separation 

 of the L4-sclerites in the anterior ventral wall.
