heavier distally. The membranous basal half (30 in fig. 268-270) of hla becomes introverted 

 in the retraction of hla (fig.270, 271). The terminal leftward-bent part of hla has a groove 

 along its anterior surface (hge in fig.266), whose ventral wall has a distinct notch (45 in 

 fig.266). 



The part to the right of the fpe-infolding has in its center a deep invagination to the anterior 

 (pouch Ive in fig.268, 269) and a spine to the posterior (via in fig.268); both contain parts 

 of sclerite L2. The anterior part of the Ive-pouch is a narrow tube-like apodeme (Ive- 

 apodeme) with a flattened and broadened top. It is completely sclerotised by L2 - except 

 for a membranous stripe (44 in fig.266) in its right-ventral (more anteriorly) or right (more 

 posteriorly) wall, which does not reach the top of the apodeme. Roughly in the middle of 

 L2, the ejaculatory duct joins the Ive-pouch from the right (fig.268), and Ive becomes 

 much broader. At this point, the right edge of the Ive-apodeme (with the membranous 

 stripe 44) bends anteriad to continue into a dorsal fold of the ejaculatory duct D (fig.268, 

 269). The ventral main part of the ejaculatory duct extends to beneath the Ive-pouch 

 (fig.268, 269; cross-section in fig.270) and wraps partly around it from ventrally (fig. 270- 

 272). In the area posterior to the confluence of the Ive-apodeme and the dorsal part of the 

 ejaculatory duct, L2 is a groove-shaped sclerotisation in the left edge of the Ive-pouch 

 (cross-sections in fig. 270-272). This groove-shape of L2 extends posteriad as far as to the 

 posterior end of edge 7 (fig.270, 273), where L2 becomes completely restricted to the 

 dorsal wall of the Ive-pouch. 



Posterior to this point L2 forms the sclerotisation of the via-spine (fig. 272-275). via has 

 a longitudinal groove in its right-dorsal wall (vge in fig. 272-275), whose anterior end 

 deepens to form a small, bulb-like, and heavily sclerotised apodeme (vge, tve in fig.273). 

 The phallomere-gland P opens to the right of the tve-apodeme. The ventral wall of the 

 left complex has some outfoldings in the area beneath the ejaculatory duct (47, 48, 49 in 

 fig.266, 271, 272). In between these outfoldings and posterior to them the ejaculatory duct 

 opens to the outside, and this area can be regarded as the genital opening. Dorsal to and 

 to the left of the via-process there is a dorsoventrally curved membranous lobe (via in 

 fig.266, 268, 270). 



The tendon ate (fig.266, 268, 271) has its origin in the anteriormost ventral wall of the 

 genital pouch; it is a long and thin invagination of the cuticle with sclerite L4V in its 

 anterior dorsal wall.
