The number of families still existing is 32 while the remaining 40 families are said to be extinct (Issei mentions a total of 40 extinct families in the english translation on Baka-Tsuki).

4 members of Sairaorg Bael's peerage are from the extinct families.

Clan 65: Andrealphus should be set to extinct (only mentioned member is Coriana Andrealphus).

Quote from Volume 8 (Extra Life. The Fun Family of the Gremory - Part 3):

"Splendid. Then what houses among them have become extinct."

"Marbas, Valefor, Buer, Gusion, Leraje, Eligos, Botis, Bathin, Marax, Ipos, Aim, Bune, Ronove, Foras, Gaap, Marchosias, Halphas, Malphas, Raim, Wepal, Sabnock, Vine, Bifrons, Haagenti, Crocell, Alocer, Caim, Murmur, Orobas, Ose, Amy, Zagan, Andras, Flauros, Andrealphus, Cimeries, Amduscias, Decarabia, Seere, and Andromalius! H..How’s that!"

This time I’m not as confident as before! But Beelzebub-sama nods.

"Correct. You did well. I thought that you wouldn’t know about it because you became a reincarnated devil recently. It was supposed to be a nasty problem but….. I will give you a pass."
