    Description

    This is a very small spider. The male has a 2 mm body length and is smaller than the female which has a 3 mm body length. The uniformly orange-red abdomen is most distinctive, whilst the head is darker almost back. There is also a blackish patch at the rear of the abdomen which is probably best seen from beneath. There are no other spiders with a similar appearance.
