This species is endemic to the lower Pecos River basin, Texas, the United States.[2]
Genus transfer
When originally described in 1935, the phantom cave snail was assigned to the genus Cochliopa. Following a detailed examination of shell and anatomical characteristics along with genetic sequencing it was transferred to the genus Pyrgulopsis in 2010.[2]
gollark: Flip-flop things not implemented on top of other gates would be stateful, wouldn't they?
gollark: SRAM cells need power constantly or they lose data.
gollark: Flash memory is also implemented in silicon and does nonvolatile storage using some black magic with a weird type of transistor.
gollark: This is also only stateless deterministic gates.
gollark: Oh, right.
