Scientific Name: Arkys lancearius

Other Common Names: Triangular Spider

Species documented in 1837 by Walckenaer.


The female triangular spider (lancearius species) can grow up to 7.5mm in body length, with the male growing to approximately 5.5mm (Mascord, 1970).

It has a distinctive triangular abdomen, and the first two pairs of legs are strong and face forward similar to that of salticid spiders (Atkinson, 2006).

This species uses ambus tactics to catch prey, and therefore does not build a web (Atkinson, 2006).
