Left complex 



L4 is a group of five sclerites: The crescent-shaped L4C occupies the whole left edge and 

 the anteriormost left ventral wall of the left complex (fig. 53). That part along the left edge 

 has a distinct dorsal extension to the right (L4d in fig. 53), the end of which forms a spine 

 sla. Along the whole of L4C there runs an apodeme swe (fig. 53-56), whose anterior part 

 is beam-like by the cuticle being thickened (anterior cross-section of swe in fig. 54); to 

 the posterior this thickening decreases, and swe becomes more and more groove-shaped 

 (posterior cross-section of swe in fig. 54). The sclerites L4D, L4E, L4F, and L4G lie in 

 the ventral wall of the left complex. L4D bears a node-like process nla (fig. 56, 57). L4E 

 and L4F are simple plates. L4G occupies the ventral wall of a large ventral lobe via (= 

 ventral phallomere; fig. 53, 54, 57), and its posterior part is upcurved. 

 In the center of the left complex there are two pouches pne and Ive (fig. 53-56), which 

 contain the sclerites LI and L2. The anterior part of LI lies in the ventral wall of the 

 small and flat pne-pouch (fig. 53, 54). The posterior part of LI extends onto a broad lobe, 

 which is divided into three processes posteriorly (fig. 54, 55): the two short, membranous 

 dca (left side) and the long, sclerotised loa (right side). Along the lateral and posterior 

 edges of this lobe the cuticle bends ventrad and anteriad (fig. 55) as far as to the edge 6, 

 where it turns posteriad again. The phallomere-gland (P in fig.55, 56) opens immediately 

 posterior to edge 6. 



The large sclerite L2 adjoins to the right of LI (fig. 53, 54), and the two sclerites articulate 

 (A2 in fig. 53, 54). From A2 sclerite L2 extends to the right, curves ventrad and - becoming 

 narrower - back to the left; then it bends posteriad and runs to the posterior edge of the
