Biology
Phylloneta impressa builds a similar retreat to that of P. sisyphia and in the similar habitats. Both species can sometimes be found together on gorse, heather and thorny bushes, below its retreat the spider spins the typical tangle web which gives some members of the family Theridiidae the common name tangle-web spiders.

Why this record matters
The phrase “species of arachnid” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jan 9, 2025. The linked authority identifier is Q150446. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
