Summary 
The Brazilian cockroach originally described as Blatta linearis by 
Serville has been referred to the genus P arasphaeria by Brunner ; it is 
not a member of this ovoviviparous genus ( Blaberidae) . P. linearis 
is oviparous with characters placing it in the subfamily Nyctiborinae 
(Blattellidae) , and Pararnuzoa n. gen. is erected for this species. 
The male genitalia, of P arasphaeria ovata (Blanchard) indicate that 
it is a member of the Epilamprinae and is not close to Perisphaeria 
(Perisphaeriinae) as suggested by Brunner.
