Attulus inexpectus
species of arachnids
Attulus inexpectus is a species of spider from family Salticidae, found in from Europe (including southern England) to central Asia. It was previously misidentified as Attulus rupicola (syn. Sitticus rupicola).
Until 2017, it was placed in the genus Sitticus.
Description
Attulus inexpectus females have a body length of about 6–7 mm (0.24–0.28 in), males being slightly smaller at about 4–5 mm (0.16–0.20 in). The fourth leg is the longest, about 5.5 mm (0.22 in) in females and about 4 mm (0.16 in) in males. Both sexes are generally brown to dark brown in overall coloration, males being darker than females. Both the carapace and abdomen have stripes and patterns formed by whitish or otherwise paler hairs, the carapace pattern being more distinct in males, with three longitudinal whitish stripes and a similarly coloured lateral border with the posterior part having a short line extending inwards.
Taxonomy
Attulus inexpectus was first described in 1997 by Dimitri Logunov and Torbjörn Kronestedt (as Sitticus inexpectus). The specific name inexpectus means "unexpected"; the species was separated from Calositticus rupicola (then Sitticus rupicola), the authors stating, for example, that all spiders previously identified as S. rupicola in England were in fact the new species A. inexpectus (then Sitticus inexpectus).
“Attulus inexpectus” enters the record as species of arachnids. Crown Archives preserves that source wording while asking what Attulus, inexpectus and species can confirm, complicate or overturn.
Why this record matters
“Attulus inexpectus” is worth following because a concise public description often conceals a longer documentary argument. Here, Attulus, inexpectus and species provides the most credible route into that argument.
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 Mar 30, 2026. The linked authority identifier is Q116263617. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2017 and 1997.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. 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.
