5.14. Blaberus craniifer (Blattaria, Blaberidae) 



All figures are side-reversed and show mirror-images of the original structures. In the subsequent 

 descriptions and in the homology discussions (chapter 6.) the terms "left" and "right" will also be 

 exchanged. (This will be practised in other Blaberidae, too: Blaptica, Byrsotria, Nauphoeta). The 

 natural orientation is shown in fig.295b and 297b. 



Left complex 



The left complex resembles that of Parcoblatta. Again, a deep infolding from the posterior 

 (fpe in fig. 299-302) divides the left complex into a left part with the retractable hla-hook 

 and its L3'-sclerite and a right part with the long L2'-sclerite. 



The left part has the shape of a bulge whose left and ventral walls are occupied by sclerite 

 L4U'. The hla-hook evaginates from the posterior wall of the bulge; when retracted, hla 

 hes in the center of the bulge (fig. 295a, 299; all figures show hla in a more or less retracted 

 state). Only a small distal part of hla is sclerotised by L3'. Most of the extensive 

 membranous basal part (30 in fig. 299-302) of hla becomes introverted when hla becomes 

 fully retracted, hla can be retracted more deeply than in the previous species. (Full 

 retraction is shown in fig. 295a, with the sclerotised part of hla completely veiled by 

 membrane; in the other figures hla is only partly retracted - to an extent corresponding 

 to the maximal retraction in Parcoblatta). The leftward-bent terminal part of hla has a 

 groove along its anterior surface (hge in fig. 297a), whose ventral wall has a distinct notch 

 (45 in fig.297a). 



The part to the right of the fpe-infolding has in its center a deep invagination to the anterior 

 (pouch Ive in fig.299, 300) and a sclerotised process to the posterior (via in fig. 299); both 

 contain parts of sclerite L2'. The anterior part of the Ive-pouch is a short tube-hke apodeme 

 (Ive-apodeme) with a flattened and broadened top. Most anteriorly the Ive-apodeme is 

 sclerotised all around, more posteriorly the right wall is membranous (44 in fig. 297a, 299, 

 300). Roughly one third down from the top of L2', the ejaculatory duct D joins the Ive-
