Pseudhapalopus sp. columbian short hair - info?

I recently received a tiny sling of this species as a freebie with the rest I was buying. Right now I'm following the standard protocol for keeping a baby sling, but I'd like to know what to expect when this sling gets older. So far I haven't had any luck finding info specific to this species, just a few care sheets and notes about others of this genus. I'm wondering if they are terrestrial or burrowers? Do they require an arid setup or more humidity? How big do they get? Are they docile or skittish?

Hmmm I got one of these as a freebie as well and am having similar problems finding info on them.

they were found in the north of tolima. in drier regions, at 1000 m asl.
they are burrowers.
