sclerotises a process (dca in fig. 177, 178) and has a plate-like extension to the left, which 

 is separated from the main part of LI by a strip of weaker sclerotisation (22 in fig. 176, 

 177). 



The complex sclerite posterior to LI is composed of L4T - the sclerotisation of the spine- 

 shaped pda - and L2C - the sclerotisation of the cup-shaped paa (fig. 176-179). pda is 

 almost completely sclerotised in its dorsal wall but only basally in its ventral wall (fig. 179, 

 182), and it resembles a hypodermic needle: At its pointed end (26 in fig. 182) the cuticle 

 is invaginated to form a very narrow channel (sbe in fig. 182) which runs back through 

 the whole spine and whose end is expanded and bulb-like (sbe in fig. 182, 183; possibly 

 the reservoir of a gland). The paa-process is completely sclerotised. At its right base the 

 cuticle is deeply invaginated to form a heavily sclerotised hood-shaped apodeme (boe in 

 fig. 179, 182, 183) which caps the right end of the sbe-bulb (fig. 182). The membrane (25 

 in fig. 178, 179, 182) that adjoins this L4T+L2C-sclerite ventrally is somewhat invaginated 

 anteriad, and here the phallomere-gland opens (P in fig. 178, 179). Ventral to and to the 

 left of this invagination the membrane extends posteriad towards the transverse edge 23, 

 along which the cuticle bends ventrad and anteriad to continue into the dorsal wall of the 

 Ive-pouch (fig. 180). 



The Ive-pouch spans almost the whole breadth of the left complex. (The edge along the 

 bottom of the pouch is labelled 7 in fig. 180). Its dorsal wall is largely occupied by the 

 sclerites L2A (left part) and L2B (right part), which articulate with each other (A4 in 

 fig. 180). In the area around A4 the Ive-pouch has a very deep recess from anteriorly. The 

 right part of L2B bends dorsad and back to the left along the longitudinal part of edge 

 23 (compare fig. 178 and 180). This dorsal part of L2B articulates with LI anteriorly (A2 

 in fig. 176, 178, 180); posteriorly it has an extension to the left (24 in fig. 176, 178). L2A 

 extends like an arch along the margins of the left dorsal Ive-wall. Only in the anteriormost 

 part of the Ive-pouch L2A enters the ventral wall (fig. 181). At the left posterior end of 

 the Ive-pouch the sclerite abruptly narrows, leaves the pouch (sclerotisation now 

 designated L4S, fig. 178, 180, with L4d as its distalmost part), and curves into the dorsal 

 wall of the left complex (fig. 177, 178). 



The membranous ventral wall of the Ive-pouch is at the same time the anterior dorsal wall 

 of the vla-lobe (fig. 174, 180, 181). The ejaculatory duct (D in fig. 178-181) opens far on 

 the right into this membrane. Dorsal to the genital opening there is a small membranous 

 outfolding (goa in fig. 177, 179-181). L4R in the ventral wall of the vla-lobe is a transverse 

 plate with a ribbon-like anterior extension (fig. 174, 181). The small sclerite L7 lies in the 

 anterior right edge of the vla-lobe and is in close contact with a ribbon-like extension of 

 the R2-sclerite of the right phallomere (R2m in fig. 174, 191-193). Another small sclerite 

 L8 lies in the right dorsal wall of the left complex (fig. 176, 177).
