Yeah that's a tough one. I can't find any information on that exact species either, not even in the scientific literature. The best I could do was this website (
http://www.crustawelt.de/wbb3/8743-procambarus-vasquezae.html) which is actually in German, but it talks about
Procambarus vasquezae, which sounds similar. Google Chrome translated it and this is the OP of that thread in English:
"Mexico Size: Males up to 7, females about 6 cm -coloring: dark brown, with large bulky bewarzten scissors -pool size: for a pair of at least 60 cm length -Water levels: at the data on the Internet give a hardness of at least 10 I think the crabs and multiply successfully in GH 3-5! -socialization: They are well suited for a community tank, I would recommend a socialization but with sturdy bottom dwellers. The crabs share sometimes very nice when someone gets too close. Injuries are real but not like it. With shrimp it should also go without problems, but even so I have not tried yet. temperature: 18-25 degrees -food: Do not go to plants, some reports of seizure of Java moss I can not confirm. I feed my crabs to feed the list here in the forum. Crayfish are warmly and also against the cheeky residents successfully defended. leaves are used as a retreat. Description: The breeding of crabs was easily possible for me, the rearing of the young crabs redundant but I have made in a separate bowl. The fish the young crabs taste too good."
You could also ask over at

As far as breeding, I wouldn't expect it to be too much different from breeding other species of that genus. If you're not familiar with breeding crayfish, just let me know and I'll see if I can give you advice!
