"The Kauaʻi cave wolf spider is only known to occur in a few caves in a lava flow with an area of 10.5 km2 (4.1 sq mi) in the Kōloa–Poʻipū region of Kauaʻi, Hawaiian Islands, and only six populations are known to exist. Unlike most wolf spiders, it produces only 15 to 30 eggs per clutch. The female carries the egg sac in her mouthparts until the spiderlings hatch. The Kauaʻi cave wolf spider was discovered in 1973. Counts have never documented more than 30 spiders or 80 amphipods.
