Transcription
Distribution
The piano flat spider is found throughout the Waikaia Forest and at other locations in northern Southland and west Otago.[4]
Description
Juveniles are pale white with no markings, but develop pigmentation after several molts.[2]
Egg sacs are pale cream or white in colour.[2]
Habitat
P. isolata has been observed living in leaf litter and rotting logs on the forest floor.[5][6]
Behaviour and diet
The piano flat spider is nocturnal. It is an active hunter and does not build a web, instead using a large claw on the end of its first and second legs to seize prey, which it bites repeatedly.[4][7]
Egg-sacs are laid in the cavities of fallen logs in late spring to early summer. After three to four weeks, juveniles emerge from a small hole at the base of the egg-sac.[8]
Conservation
The piano flat spider is classified as At Risk (Relict) by the Department of Conservation.[9]
