Description
editThe backs of spiders in this genus are marked with a dagger shape, outlined in black and surrounded by a triangular folium. On each side of the dagger there are parallel rows of orange-brown dots. Body length of females ranges from 4.3 to 8 millimetres (0.17 to 0.31 in), of males from 3.6 to 6.5 millimetres (0.14 to 0.26 in)[3]
Behavior
editAs the other species are only known from museum specimens, only the natural history A. hamata is known in any detail.[3][4]
