Segestriidae

Female Ariadna dysderina, copyright S. Pearson.


Belongs within: Basalhaplogynae.

The Segestriidae are a cosmopolitan group of spiders that construct tubular retreats from the mouth of which extend trip-lines. The third pair of legs is held directed forwards alongside the first two pairs, with only the fourth pair directed rearwards (Jocqué & Dippenaar-Schoeman 2007).

Characters (from Jocqué & Dippenaar-Schoeman 2007): Medium-sized; six eyes present in two rows, with lateral eyes contiguous, posterior median eyes closely grouped; legs with three tarsal claws; third pair of legs directed forwards; posterior tracheal spiracles far forward, just behind booklung slits; ecribellate; haplogyne; female palpal claw turned inwards over almost 90°.
