Spelungula is a monotypic genus of South Pacific large-clawed spiders containing the single species, Spelungula cavernicola, or the Nelson cave spider. It was first described by Ray Forster, Norman I. Platnick, & Michael R. Gray in 1987,[2] and has only been found in caves in the northwestern part of New Zealand's South Island.[1][3]
Etymology
The genus name is derived from "spelunca", which is latin for cave and is feminine in gender. The species name "cavernicola" refers to the species restriction to caves.[2]
Description
It is New Zealand's largest known spider, with a legspan of 13 to 15 centimetres (5.1 to 5.9 in) and a body length of 2.4 centimetres (0.94 in), and its main prey is cave weta.[4][5]
Conservation status
It is one of the few spider species afforded legal protected under the New Zealand Wildlife Act.[6][7] It is classed as "Range Restricted" and stable in the New Zealand Threat Classification System.[8]
In May 2022, the Crazy Paving Cave in Kahurangi National Park, where the spiders are known to breed, was closed for a year in an attempt to help the population to recover.[9]
