left complex; here it ends at the base of a small process paa (fig.56). This arch-like course 

 of L2 extends along the margins of a pouch Ive, which is, like L2 itself, curved dorso- 

 ventrally (in contrast to Mantodea, whose Ive-pouches extend within one plane). Thus, the 

 left parts of the Ive-pouch and of L2 lie beneath the pne-pouch as in Mantodea, but their 

 right parts curve upwards into the same plane which also contains sclerite LI. The edge 

 along the bottom of this Ive-pouch is labelled 7 in fig. 54, 55. The invagination of the Ive- 

 pouch starts immediately anterior to the paa-process (posterior end of 7 in fig. 55), and it 

 ends in the anterior dorsal wall of the left complex (dorsal part of 7 in fig. 54), where L2 

 leaves the pouch and approaches LI. According to the curvature of the Ive-pouch, it is 

 preferable to name that wall of Ive containing sclerite L2 the inner one (instead of dorsal) 

 and the opposite wall the outer one (instead of ventral). L2 is restricted to the inner Ive- 

 wall; only most posteriorly it bends into the outer (or ventral) Ive- wall. Then it leaves the 

 pouch and ends on the paa-process (fig. 55, 56). paa is, except for another small distal 

 sclerite (probably a split off part of L2), membranous (fig.55-57). 



The membranous outer (or ventral) wall of the Ive-pouch is at the same time the dorsal 

 wall of the vla-lobe (fig. 53-56; in the figures via is pulled to the right). The ejaculatory 

 duct (D in fig. 53) opens into this wall. Dorsal to the genital opening there is a small 

 membranous lobe goa. The ventral wall of the vla-lobe is sclerotised by L4G. The 

 posterior edge of the vla-lobe continues leftward into the posterior edge of the remaining 

 left complex, where the paa-process follows (fig. 53, 57). 



The large hook hla is evaginated from the left anterior ventral wall of the left complex, 

 hla is, except for its basalmost walls (30 in fig. 54-56), completely sclerotised by L3 

 (fig. 53-55). hla is retractable for a very short distance, since the basal membranous walls 

 30 can be introverted (this state is shown in the figures). 



Right phallomere 



The right phallomere is only schematically shown in fig.330f. Differences to Eurycotis 

 (following species) will be explained in 6.7.4., 6.7.5., and 6.7.6.

 Left complex 



The left complex resembles that of Archiblatta. L4 is a group of three sclerites: The 

 crescent- shaped L4H occupies the left edge and the left anterior ventral wall of the left 

 complex (fig. 65, 66). That part of L4H in the left edge broadens in its posterior half. A 

 beam-like apodeme swe (fig. 65, 66; anterior and posterior cross-section in fig. 66) runs 

 along L4H. At the anterior end of the swe-apodeme L4H bends abruptly posteriad and 

 broadens into a plate bearing the node-like process nla (fig. 68, 69) in its left half. The
