Fig. 335: Spurs on fore-tibiae of Blattaria. - The sclerotisation and the spurs of the left fore-tibia are 

 shown; basalt, distali. The area bordered by straight or undulate lines is the sclerotisation of the 

 tibia. This sclerotisation is cut lengthwise along the ventral = inner edge of the tibia (undulate Hues) 

 and unfolded. Black arrows mark the dorsal = outer edge of the tibia. Black dots represent the bases 

 of spurs. Most spurs are labelled with numbers (apical spurs) or small letters - according to the 

 homology relations assumed. Some apical spurs have their base outside the tibial sclerotisation. 



vestigial in Cryptocercus, has a vertical orientation also in Lamproblatta and 

 Sphodromantis, and the posterior main part of the sclerite of Blattinae and 

 Polyzosteriinae is vertical, too. (These sclerotisations lie within the posterior wall of 

 the bulge containing the spermathecal opening (compare Klass, in press: fig. 2, 3). 

 Thus, the vertical orientation is certainly not an autapomorphy of this grouping. 

 15 "Sclerite R2* with a hind tubercle large and rounded." Misidentification (C). 



Cryptocercus + Therea + Eucorydia 



25 "Fore tubercle of R2* very small." Misidentification (C). 



26 "Hind tubercle of R2* fused with R3v*." Misidentification (C). Moreover, RIF (= 

 R2*) of Cryptocercus is in no place fused with R3 (= R3v*). (According to fig. 6 of 

 Grandcolas the articulation A3, fig. 163, is probably regarded as the point of "fusion"). 



27 "Frontal maculae of circular outline." These frontal maculae are more or less clearly 

 demarcated cuticular areas median to the antennal bases. I have investigated them in 

 the following species (from externally only): In Ergaula capucina they are clearly 

 demarcated and - like in Grandcolas, fig. 16 - drop-shaped. In Deropcltis and 

 Polyphaga they are nearly circular. In Cryptocercus and Lamproblatta no maculae 

 could be found. According to this distribution of the character states the autapomorphy 

 is refuted. 



28 "Postclypeus little or even not rounded." It is not clear whether this feature refers to 

 (1) the bulging of the postclypeus or to (2) the arch-like course of its anterior margin 

 (= sutura epistomalis). According to (1), this feature would be like in e.g. Periplaneta
