Attulus inexpectus is a species of spider from family Salticidae, found in from Europe (including southern England[2]) to central Asia.

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.

The two species can be distinguished by the pattern of white hairs on the carapace of the male – in C. inexpectus there is usually a short white stripe extending inwards from the posterior part of the carapace, and by the detailed shapes of the male palpal bulb and the internal female genitalia.

It is a lowland species (thus contrasting with A. rupicola), typically found near to water, either coastal or inland.

[3] In southern England, where the species is found from April to October, it lives in coastal shingle and tidal litter, often adjacent to saltmarshes.
