5.8. Polyphaga aegyptiaca (Blattaria, Polyphagidae, Polyphaginae) 

 Left complex 



Sclerite LI is situated in the central dorsal wall; its anterior part lies within a deep pouch 

 (pne in fig. 117). Beneath the pne-pouch there is another very deep and broad pouch (Ive 

 in fig. 118, 122), with the arch-shaped L2-sclerite extending along its edges. The left 

 posterior dorsal wall contains the sclerotisation of two processes (pda and paa in fig. 117, 

 118) and of an intervening invagination (dte in fig. 117, 118), which is firmly connected 

 with the L2-sclerotisation in the Ive-pouch around the posterior edge of the left complex 

 (10 in fig. 118, 122). This dorsal sclerotisation is composed of parts of L2 (right part) and 

 of L4 (left part: L4N). Sclerite L8 lies in the right dorsal wall of the left complex (fig. 117). 

 From the left wall of the left complex there protrudes a large hook-process (hla in fig. 117) 

 with its L3-sclerite. The large L4M- sclerite occupies the ventral wall (fig. 115, 117, 126). 

 Another L4-sclerite lies within the ventral base of the hla-hook (L4K in fig. 122- 124). 

 The anterior hood-shaped part of LI largely occupies the walls of the pne-pouch (fig. Ill, 

 118, 119, 120). In the left-dorsal half of the pne-pouch the walls are membranous - 

 especially in the posterior part, where the phallomere-gland (P in fig. 11 8, 120, 121) opens 

 from ventrally. The anterior end of LI is flat and plateau-like. Posteriorly LI leaves the 

 pouch and has an arm-like extension on each side (fig. 11 8, 120, 121). The extensions 

 curve ventrad and approach each other again (fig. 121). The membranous cuticle enclosed 

 by this (open) sclerite-ring forms two cushion-like evaginations (dca in fig. 117, 120, 121). 

 The Ive-pouch (fig. 11 8, 122) spans almost the whole breadth of the left complex. (The 

 edge along the bottom of the Ive-pouch is labelled 7 in fig. 122, 123). L2 occupies the 

 margins of the dorsal (fig. 122) and ventral (fig. 123) walls of the Ive-pouch. The left part 

 of L2 in the dorsal Ive-wall broadens posteriorly and bends around the posterior edge of 

 the left complex (along 10 in fig. 118, 119a, 122) into the dorsal wall. Here it continues 

 into the sclerotisation of the paa- and pda-processes and of the dte-invagination (fig. 1 17- 

 119b; L2 and L4N, with the border between them somewhere within dte). The pda-process 

 is fmger-Uke; the paa-process is saucer-shaped and partially encloses the dca-processes 

 from left-ventrally. The pda-sclerotisation has a tongue-like extension to the left (L4d in 

 fig. 11 8, 123, 124). The paa-sclerotisation has an arm-like extension to the right (12 in 

 fig. 11 8, 119a). The right parts of L2 and of the Ive-pouch curve dorsad and back to the 

 left (fig. 11 8, 122, 123), and along this curvature the Ive-pouch becomes rapidly less deep.
