- "Hook sclerite L3d* directed internally and posteriorly." Misidentification (B). 



- 'Tubercles of the sclerite R2* fused together." Misidentification (C). 



- "Sclerite L3v* plate-like." Misidentification (B). 



- "Spermatheque des femelles nettement bifide" (Grandcolas & Deleporte 1992). The 

 polarity of this character (spermatheca bifid or unbranched) is unclear, but the bifid 

 condition is certainly not a synapomorphy of Cryptocercus und Polyphaginae since it 

 is also present in e.g. Blattinae, Polyzosteriinae, Lamproblatta, and Mastotermes 

 (McKittrick 1964).

1 1 "Presence of an expanded and warty area on the inner basal part of the anterior arch." 

 In the female genitalia, the left and right second valvifers are narrowly connected with 

 each other at their anterior margins by a median transverse bridge (anterior arch of 

 McKittrick 1964). Grandcolas probably refers to a posteriad expansion of the 

 sclerotisation of the second valvifers towards the bases of the second and third valves, 

 which is lateral to this transverse bridge (compare Klass, in press: fig. 2, 3). "warty" 

 might refer to the small and thick setae in this area. The expansions as well as the 

 bristles are present in Cryptocercus, but also in e.g. Sphodromantis, Lamproblatta, and 

 Eurycotis (own investigations). If I have understood this autapomoiphy correctly, it 

 has to be refuted. 



12 "Apical spur lacking on the outer caudal margin of the fore tibiae." I have investigated 

 the spurs of the fore tibiae in Polyphaga, Ergaula capucina, Cryptocercus, 

 Lamproblatta, and Deropeltis (fig.335a-e). All these species have 5 apical spurs, whose 

 bases are either outside or inside the sclerotisation of the tibia. These apical spurs can 

 be homologised one by one, if the slightly curved row of spurs z, y, x .... is taken as 

 a landmark. The apical spur at the distal end of this row, which is always outside the 

 tibial sclerotisation, has been arbitrarily termed 1. Ergaula, Polyphaga, Lamproblatta, 

 and Deropeltis correspond in their sets of apical spurs: Two adjacent spurs at the inner 

 caudal margin of the fore tibiae are outside the tibial sclerotisation (1,5), three other 

 spurs at the outer caudal margin are inside the tibial sclerotisation (2,3,4). Only in 

 Cryptocercus spur 5 is inside the tibial sclerotisation. Hence, the apical spurs of 

 Cryptocercus and Ergaula do not show any special situation in common differing from 

 the other species. The autapomorphy is refuted. 



13 "Neoformation N* adjacent to LI horizontal." Misidentification (D). 



14 "Spermatheca sclerite vertical." Grandcolas probably refers to the orientation of the 

 spermathecal plate of the female genitalia (McKittrick 1964). This sclerite, which is
