5.12. Nahublattella sp. (Blattaria, Blattellidae, Plectopterinae) 



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 Plectopterinae, too: Euphyllodromia, Supella). The natural 

 orientation is shown in fig. 236b and 239b. 



Left complex 



Sclerite LI' lies in the posterodorsal wall (fig.243). The L2'-sclerotisations (L2D% L2E') 

 are in the center of the left complex (fig. 242-244). The anterior part of L2D' forms a 

 tube-like apodeme (Ive-apodeme = anterior part of Ive-pouch), to the right of which the 

 ejaculatory duct (D in fig. 242) opens. At the left base of this apodeme, L2E' forms, 

 together with a L4'-sclerotisation (L4N'), a large trifid process via (fig. 244, 245). In the 

 anteriormost ventral wall of the left complex lies sclerite L4V', which bears the whip-like 

 process nla (fig. 239a, 247). The left posterior edge of the left complex bears a long hook 

 hla with its sclerite L3' (fig. 242-244). The base of the hook is partly enclosed by the 

 lateral sclerite L4U'. 



The left posterior part of the left complex resembles a bulge whose left wall is sclerotised 

 by L4U' (fig. 242-244). The hla-hook is evaginated from the posterior wall of this bulge; 

 its distal half is sclerotised by L3'. The membrane of the basal half (30 in fig. 242-244) 

 can be introverted, and hla can be retracted in the same way as in Anaplecta (all figures 

 show hla in its retracted state). Right-ventral to the hla-base the posterior wall of the left 

 complex folds inwards (fpe in fig.242-245): This fpe-fold separates the area of hla from 

 the other parts of the left complex. The dorsal wall to the right of hla contains a bristle 

 area (35 in fig.242). Ventral to this area there is a flat pouch invaginated to the anterior 

 (pne in fig.242, 243). The ventral wall of the pne-pouch is sclerotised by the anterior part 

 of LI'. The cup-shaped posterior part of LI' occupies a bulge-like process (dca in fig.243, 

 244) beset with setae. Beneath the dca-process there is a membranous lobe (cla in fig. 244). 

 Anteroventral to the cla-lobe the cuticle is again evaginated: The posterior end of sclerite 

 L2D' forms a bifid process (psa in fig. 244-246). 



Figs. 234,235: Nahublattella sp. (Blattaria, Blattellidae, Plectopterinae) - All figures show mirror- 

 images of the original preparations. - 234; Male postabdomen in dorsal view; with phallomere 

 complex, subgenital plate, marginal parts of abdominal tergites 9 and 10, subanal lobes (covered), 

 paraprocts (covered), Pv-sclerites, distal part of rectum, basal parts of cerci, and part of musculature. 



- 235: Same as in fig. 234, after removal of further parts of abdominal tergites 9 and 10 (especially 

 TlOv). Distal part of rectum and basal parts of cerci cut open. Another part of musculature shown.
