Xeropigo tridentiger (ex Corinna tridentigera)

This is an endemic spider (in an endemic genus) from St Helena. It is a brown spider up to 16 mm long, with spiny legs. Dark marks radiate from the centre of the carapace, which is much narrower in the front around the eyes. The chelicerae are large but the fangs relatively small and pointing inwards, in contrast to Tecution (see Miturgidae). X. tridentiger is normally found under stones, where one can also see the disc‑shaped silky egg sacs. The species occurs at low to middle levels in dry parts of the northern half of St Helena.
