Source-derived summary

Idiosoma cupulifex is a trapdoor spider in the Arbanitinae subfamily of the Idiopidae family. It was first described as Aganippe cupulifex by Barbara York Main in 1957. In 2017 Michael Rix and others transferred it to the genus, Idiosoma, to give the name Idiosoma cupulifex, (the name accepted by the Australian Faunal Directory, and the World Spider Catalog, and GBIF).

It is found only in the south-west of Western Australia, in open forest and woodland.

Editorial summary

This brief starts where responsible research should: with the source description of “Idiosoma cupulifex” as taxon, (Main, 1957) species of idiopidae. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewA practical orientation to terminology and classification, particularly when read beside dated observations, specimens or technical literature. The current lead gives the account dated anchors—1957, 2017—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Idiosoma, cupulifex and taxon can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as taxon, (Main, 1957) species of idiopidae. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jan 27, 2026. The linked authority identifier is Q111593956. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1957 and 2017.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
