Arkys lancearius, is commonly known as the Triangular Spider, named from the distinctive triangular and heart-shaped abdomen. It is a brightly coloured and patterned spider common along the east coast of Australia, from Queensland, down through New South Wales, Victoria, parts of South Australia, south-eastern parts of Western Australia and Tasmania.
The male of the species are smaller then the female, the body length of the male is about 5.5 mm, whilst the females are about 8 mm. Whilst the rear pairs of legs are small, the front two pairs of legs are large, enabling them to easily grab small insects. The body colour vary from yellow, orange, red and with pale jewel-like markings on the triangular shaped abdomen.
