Help with deciphering an Ejutla record

Hi everyone,

I've been trying to figure a few things on a marriage record on my own to no avail.
The record is #173. Here is the link. https://familysearch.org/pal:/MM9.3.1/TH-1-18567-2737-28

1. There is an abbreviation after the name of the groom's mother that I can't read. Her name is Ma. Simona Araiza (pcto.?). Has anyone else seen this abbreviation? Any idea what it means?

2. There is also the bride's mother's name that I can't fully make out. I think it might be Lorenza Gertrudis Florencia. Is Florencia a given name or her surname? The summary on the side of the record shows a different surname than the one shown in the body of the record. I can't make it out, but it doesn't look like Florencia.

3. It states Jose Eufracio Araiza is from Ixtlapuacan. I researched this and couldn't find it. I did find some Ixtlahuacan locations. There is an Ixtahuacan del Rio and Ixtahuacn de los Membrillos that are closer to Guadalajara. I also found an Ixtlahuacan de Santiago, but that is in Union de Tula. Has anyone heard of Ixtapuacan?

Any help is greatly appreciated. :)
