 than one section - according to the various aspects of their relative position.

6.6. Left complex VI: The position of the phallomere-gland opening 



6.7. The elements of the right phallomere 



Fig. 321: Male postabdomen and phallomere complex corresponding to the hypothetical ground-plan 

 of Blattaria and Mantodea (on pages 175-177). 



a) Postabdomen from segment 9 on in dorsal view. 



b) Postabdomen from segment 9 on after removal of central parts of abdominal tergites 9 and 

 10; dorsal view. With marginal parts of tergites 9 and 10, phallomere complex, ejaculatory 

 duct, subgenital plate, paraprocts, epiproct, subanal lobes, supraanal lobe, cerci, and distal part 

 of rectum. 



c) Detail from left part of fig. 32 lb after removal of some dorsal parts in dorsal view. 



d) Subgenital plate and phallomere complex in dorsal view. 



e) Left complex in dorsal view. 



f) Right phallomere in dorsal view. 



g) Left complex after removal of some dorsal parts in dorsal view. 



h) Right phallomere after removal of some dorsal parts in dorsal view. Ridges pia and pva shown 

 through a window cut into ventral wall of lobe fda. 



i) Left complex in ventral view. 



k) Subgenital plate in dorsal view. Ventral wall of genital pouch with dorsal sclerotisation S9d 

 of subgenital plate retained on left side but removed on right side. 



1) Postabdomen from segment 9 on after removal of rectum, supraanal lobe, epiproct, and of 

 large parts of abdominal tergites 9 and 10, subanal lobes, and dorsal wall of genital pouch; 

 dorsal view. With lateral parts of tergites 9 and 10, phallomere complex, ejaculatory duct, 

 subgenital plate, paraprocts, ventral walls of subanal lobes, and basal parts of cerci. Dorsal 

 lobe fda cut open lengthwise in its leftmost part. All ground-plan muscles of categories p 

 (peripheral), s (phallomero-stemal), and b (between left complex and right phallomere) shown. 

 p4 only shown on right side, p6 and p7 only on left side. Dorsal part of p3 (to rectum) removed. 



m)-o) Left complex after removal of some dorsal parts in dorsal view. Each figure with some ground- 

 plan muscles of category 1 (intrinsic muscles of left complex). 



p) Right phallomere after removal of some dorsal parts in dorsal view. With the ground-plan 

 muscles of category r (intrinsic muscles of right phallomere). Ridge pia shown through a 

 window cut into ventral wall of lobe fda. 



Stippled areas are sclerotised. Abbreviations in 4.7. Elements whose presence in the ground-plan of 



Blattaria and Mantodea is uncertain are provided with "?".
