Spelungula is a monotypic genus of South Pacific large-clawed spiders containing the single species, Spelungula cavernicola, or the Nelson cave spider.[2]

Taxonomy

[edit]

This species was described in 1987 by Ray Forster from specimens collected in caves around Nelson.[3] The holotype is stored at Te Papa Museum under registration number AS.000014.[4]

Etymology

[edit]

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.[3]

Description

[edit]

It is New Zealand's largest known spider, with a leg span 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.[5][6]

Holotype of Spelungula cavernicola

Distribution/habitat

[edit]

This species is only known from caves in northwestern Nelson, New Zealand.[3]

Conservation status

[edit]

It is one of the few spider species afforded legal protection under the New Zealand Wildlife Act.[7][8] It is classified as "Range Restricted" and stable in the New Zealand Threat Classification System.[9]

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.[10]
