a spine (fig.65, 66). Sclerite L2 adjoins to the right of LI (fig.67), and the two sclerites 

 articulate (A2 in fig.67). Like in Archiblatta, L2 is dorsoventrally curved (fig.67, 68), and 

 the anterior part of L2 hes in the inner wall of a large pouch (Ive in fig. 65-68; the edge 

 along the bottom of the Ive-pouch is labelled 7 in fig. 66-68). The anteroventral parts of 

 L2 and Ive deepen strongly to the left to form a tongue-like apodeme (Ive in fig.67). At 

 the posterior margin of L2 there are three processes, the largest of which is the completely 

 sclerotised paa (fig.67). 



The outer wall of the Ive-pouch is completely membranous and is at the same time the 

 dorsal wall of the vla-lobe (fig.65-67; in the figures via is pulled to the right). The 

 ejaculatory duct (D in fig.65, 66) opens into the anterior part of this wall. Dorsal to the 

 genital opening there is a membranous lobe goa (fig. 66). In contrast to Archiblatta, the 

 main part of the vla-lobe is separated by a deep notch (9 in fig. 63) from the remaining 

 ventral parts of the left complex. The hla-hook (fig. 65-67) is like in Archiblatta. 



Right phallomere 



Sclerite R3 in the anterior (right-) ventral wall is a curved plate (fig. 74-77). The right and 

 the right anterior margins of R3 form a groove-like apodeme age (fig. 74, 77; cross-section 

 through age in fig.78). The right part of age bears a keel-like apodeme (3 in fig.74, 77). 

 Posterior to the left part of R3 sclerite R2 adjoins, and the two sclerites articulate (A7 in 

 fig.75-77). R2 forms a dental ridge (fig.74-77). Posterior to the central part of R3 the 

 ventral wall of the right phallomere is extensively invaginated dorsad and anteriad (cbe 

 in fig. 74-76; compare fig. 77 and 78). This cbe-invagination takes a position in the center 

 of the right phallomere. 



Posterior to the right end of R3 sclerite RIF adjoins, and the two sclerites are articulated 

 (A3 in fig.74, 75, 77). RIF extends from its central part behind A3 in three directions: 

 The first arm bends left-dorsad (along edge 16, fig. 77, 78) and occupies the whole right- 

 dorsal wall of the cbe-invagination (fig. 74, 75, 78). This arm forms a dental ridge (pva 

 in fig. 75, 78, 80) at its posterior margin and articulates with the left-dorsal end of R2 (A6 

 in fig. 75, 76) at its median end. The second arm of RIF extends posteriad and sclerotises 

 the anterior part of a two-pointed ventral tooth (pia in fig. 77). The third arm of RIF 

 extends posterodorsad (fig.74); its dorsal margin folds back to the right to form a sclero- 

 tised groove (rge in fig. 74); the rge-groove is a posterior continuation of the age-groove 

 on R3. 



The posterior part of the right phallomere is composed of the dorsal lobe fda (fig.74) and 

 the ventral tooth pia (fig.77, 78). fda and pia are confluent along the right edge of the 

 right phallomere and diverge towards the left. The dorsal wall of the fda-lobe and parts 

 of its ventral wall are occupied by sclerite RIH (fig.74, 76). The left part of RIH scle-
