Species text

Distribution
So far, most of the few specimens recorded from Britain have come from coastal locations, as in the south-east, and inland stony areas, as in northern England and central and eastern Scotland. On the nearby Continent Zelotes subterraneus, but not Zelotes apricorum, has been recorded from Belgium, Holland, Norway and Sweden.

Habitat and ecology
The Essex specimens appear to have occupied discarded shells on shingle beaches, but elsewhere Z. subterraneus is typically found under stones, even on mountains. Z. subterraneus is one of the shiny, all-black Zelotes species. Adults of both sexes have been recorded in late spring/early summer and late summer/autumn.

Status
The two species Z. subterraneus and Z. apricorum are very closely related (Murphy & Platnick 1986). In particular, the epigynes of the females are difficult to separate, and even the internal genitalia are very similar. For many years only Z. apricorum was recorded from Britain, so it is possible that among females identified as Z. apricorum there could have been some specimens of Z. subterraneus.

Threats
Coastal sand dunes are in some areas subject to high human pressure, resulting in erosion.

Management and conservation
Protect dune systems from excessive public pressure, particularly that due to off-road vehicles.
