These are Gorgeous Phidippus bidentatus 'Maya' males.
They are young adults.
They have been captive bred by us,  a relatively new locale to the UK.
They are a stunning black with an iridescent patch on their abdomens. 
They are a very friendly and easy to care for jumper. 
These are all brothers and were some of our hold backs we do not need.
'Maya' and one of the locales of the bidentatus species.
Please remember to provide a bright white led light directly above their enclosure for their wellbeing .
