This is a gorgeous Phidippus nikites.
Possiblemale.. 
They have been captive bred by us.
They left the nest 6/25
and are 8-10 mm .
Phidippus nikites are an arid species which thrive best with a dryer set up.
An arid (sand based) soil substrate in a Bio-Active set up with live plants works best, although if not possible,  just a (sand based) arid substrate can be used.
They prefer not to be misted.
Once set up, they are a delightful and easy Jumper to care for.
Not the biggest of Jumpers, but females can grow to 12 mm +
PLEASE remember to provide a bright white led light directly above the enclosure for their wellbeing.
