Your Paphiopedilum is actually the species
Paphiopedilum niveum. There is no other that looks like this, not even the new species
Paph. thaianum.
Paph. niveum is a low elevation native to the Langkawi Islands in Malaysia. This species typically will bloom May-July, and likes heavier watering after blooming until Sept. or Oct.
Paph. niveum will tolerate low amounts of light, but likes to be in brighter conditions. Give warmer temperatures for this species.
That's about all there is I know about it! Here is mine for comparison. Note that this species is somewhat variable.

EDIT: Thought that I would add that vegetatively, you plant resembles a
Paph. bellatulum. The solid purple and slight waviness is typical for
Paph. bellatulum, which can fool one to think it was that species out of bloom. However, yours is really
Paph. niveum. The primary hybrid between both of those species is Paph. Psyche, which is significantly different.
