Beneath via, the ventralmost part of the left complex forms a broad ventral lobe via, whose 

 edges are sclerotised by the tuberculate LIO'. The right anterior end of LIO' is connected 

 with L2'. The genital opening is more or less right-dorsal to the middle part of sclerite 

 L2', though it is hardly possible to define its exact position. 



The membranous tendon ate has its origin in the ventral basal line of the left complex 

 (Bl in fig.297a, 302); it is a short and broad invagination of the cuticle. To the left of ate 

 there is another small membranous invagination (55 in fig. 297a, 302). 



Right phallomere 



Sclerite R3' occupies the anterior (right-)ventral wall (fig.308-312a). Its right part has a 

 short extension to the posterior (fig. 308, 312a). The age-groove or -apodeme is very broad 

 at the anteriormost margins of R3'; to the posterior it soon decreases and ends on both 

 sides (fig.297a, 312a). Sclerite R2' adjoins posterior to the left part of R3'; the two 

 sclerites are broadly separated by membrane (at A7 in fig. 3 12a). The ventral anterior tip 

 of R2' lies in a small membranous pouch (56 in fig. 308, 312a,b, 313). From here R2' 

 extends left-dorsad and forms a ridge (fig. 3 10, 311). At its left end R2' is fused to the 

 large sclerite RIT' (at A6* in fig.310, 313). Next to its fusion with R2', RIT' has a 

 bulge-like cuticular thickening to the interior (ewe in fig. 308-3 10, 313). Posterior to the 

 central part of R3' the ventral wall of the right phallomere curves dorsad and anteriad to 

 form a rather indistinct central invagination (cbe in fig. 308, 310, 313; compare fig. 3 12a 

 and 313). 



The two large sclerites RIT' and R4' adjoin posterior to the right part of R3' (fig. 308, 

 309, 312a). RIT' is loosely articulated with R3' (A3 in fig.309, 310, 312a). RIT' and 

 R4' are the sclerotisations of two lobes lying one above the other, which compose the 

 posterior part of the right phallomere (fda and dla in fig. 308, 309, 313). The left end of 

 the fda-lobe is somewhat pointed (58 in fig.309, 312a), and next to this point RIT' is 

 fused to R2'. R4' mainly occupies the dorsal wall of the dla-lobe (fig. 308); its right end 

 curves into the ventral wall of the phallomere (59 in fig. 308, 309), where it closely 

 approaches articulation A3. 



The bulged sclerite R5' lies in the left- ventral part of the right phallomere (fig. 3 12a; 

 removed from the other elements in fig.311; cut through in fig.309). The right phallomere 

 can be retracted and protracted, and during this movement R5' flaps back and forth 

 (compare fig. 3 12a and 312b). 



Subgenital plate and posterior abdominal segments 



Fig. 293, 294 (posterior segments); fig. 296 (subgenital plate S9). The entire tergite 10 TIO, 

 including its ventral part TlOv, is divided along its midline. TlOv is very extensive; it 

 has a pair of extensions to the anterior, which bear node-like apodemes (54 in fig. 293).
