keys to Blattaria/Psocoptera families?

[Doug Yanega]

Just wondering if anyone knows accessible family-level keys for these
groups that would work in the neotropics. According to my notes there are
something like 30 possible Psocoptera families here (true?), and for
Blattaria I have Blattidae, Blatellidae, Blaberidae, Cryptocercidae,
Polyphagidae, and Epilampridae; these are not distinguished by Borror et
al.
Thanks in advance for pointers,
