Walckenaeria
genus of arachnids
Walckenaeria is a genus of dwarf spiders that was first described by John Blackwall in 1833. It is a senior synonym of Paragonatium, as well as Wideria, Cornicularia, Prosopotheca, Tigellinus, and Trachynella.
Some males in this group have eyes set up on mounds or turrets. In extreme cases, several eyes are on a stalk taller than the carapace itself.

This brief starts where responsible research should: with the source description of “Walckenaeria” as genus of arachnids. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as genus of arachnids. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Mar 27, 2026. The linked authority identifier is Q2518986. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1833, 2020, 1985 and 2001.
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.
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.
- Current terminology
- Classification context
- Finding cited technical literature
Primary datasets, specimen catalogues, standards bodies and the most recent peer-reviewed literature.
