homologous (fig.332e,i). Since the morphology of the respective part of the right 

 phallomere of Therea and Heterogamodes is similar to Polyphaga and Ergaula, the 

 same relations are assumed for these species. 

 - The resulting assumption that RIF of Cryptocercus is homologous with R2 of 

 Polyphaginae is also refuted. 



Sclerite N* sensu Grandcolas (D) 



Sclerite N* of both Therea and Heterogamodes certainly corresponds to L8 of Polyphaga 

 and Ergaula (fig. 117), which is situated on the rightmost part of the left complex, close 

 to the right phallomere. According to Grandcolas, a sclerite N* is also present in 

 Cryptocercus. From its relative position shown in Grandcolas' fig. 6 results that this N* is 

 R2 (fig. 161- 163): it articulates with both RIF = R2* and the left posterior end of R3 = 

 R3v* (articulations A6 and A7), and its general shape and position also fit. However, in 

 my opinion (compare in (C)) this R2 = N* of Cryptocercus is not homologous with L8 

 of Polyphaga and Ergaula but with R2 of Polyphaga, Ergaula, Periplaneta, and Eurycotis 

 (fig. 75, 135, 161; compare in 6.7.4.), and L8 is missing in Cryptocercus. 



The vp*-lobe (ventral phallomere) sensu Grandcolas and its sclerotisation (E) 



In Periplaneta, Therea, and Cryptocercus Grandcolas (fig.l, 5, 6) designates a sclerotised 

 lobe in the median ventral wall of the phallomere complex as the ventral phallomere vp* 

 (vla-lobe in my terminology). As regards Cryptocercus and Periplaneta I agree with him: 

 The lobe is the true via with sclerite L4G in its ventral wall (fig. 63, 148). In Therea, 

 however, since this species is closely related to Ergaula, the lobe concerned can be 

 regarded as homologous with the iba-lobe of Polyphaga and Ergaula, which bears sclerite 

 L7 in its ventral wall (fig. 115). 



The figures showing the general phallomere structure of Blattinae and Polyphaginae 

 (Grandcolas' fig. 2, 4) furthermore reveal that Grandcolas assumes homology for L7 of 

 Polyphaginae (including Polyphaga, Ergaula, and Therea) and L4G of Cryptocercus and 

 Blattinae / Polyzosteriinae (the white posteromedian sclerites in these figures). In my 

 opinion this assumption is wrong: In 6.2. and 6.3. the area belonging to the ventral 

 phallomere or vla-lobe of Polyphaga has been identified, and the sclerotisation 

 homologous with L4G of the other species has proved to be contained in L4M 

 (fig.325e,f,h,k); the position of the ventral insertion of muscle 16a, the position of the vla- 

 lobe relative to the Ive-pouch, and the position of the genital opening are the main 

 arguments. In 6.5. it has been shown that the Iba-lobe corresponds only to the rightmost 

 part of the vla-lobe of the other species, and that L7 is a new sclerite of Lamproblatta + 

 Polyphaga + Ergaula (and probably of at least some other Polyphaginae). 



Side-homologies according to Grandcolas (F) 



In Cryptocercus, Polyphaginae, and Blattinae Grandcolas assumes side-homologies for the 

 sclerites of the left half and of the right half of the phallomere complex. The only argument 

 is that an identical number of sclerites with similar form and position were recognisable 

 on each side of the ejaculatory duct opening (p. 146).
