[2] This species is a pale greenish yellow, almost white, with 22 or 23 pairs of legs and no eyes.

The minimum number of leg pairs found in this species (22) is also the minimum number found in the neotropical Peripatidae.

[3] This velvet worm is viviparous, with mothers supplying nourishment to their embryos through a placenta.

[5] One other troglobitic velvet worm species is known; Peripatopsis alba, from Wynberg Cave and Bats' Cave, on Table Mountain, South Africa.

Only seven individuals have been found as of 2021; four specimens collected by Dr. Stewart Peck in 1975 at Pedro Great Cave, one individual found (not collected, but confirmed photographically by Peck) at Swansea Cave by members of the Jamaican Cave Organisation (JCO) in 2010, and two more found again at Swansea Cave by the JCO in November, 2021.
