Some kind of spider I found on the floor at the nature setting at Nixon Park.
Small black spider with red spot on the top of the abdomen. Thought it might be a black widow but i dont think its the right shape and the red marking is on the top side not the underside of the abdomen. There was a hint of yellow at the top of the red mark towards the head. There was also a faint grey stripe along the top of the body from head to abdomen (visible in the picture on the glass) Quite small about the size of a thumb nail.
Sorry about the poor photo it wouldn't hold still
The corinnid sac spiders (family Corinnidae), like the other clubionoid families, have a very confusing taxonomic history. Once this family was a part of the large catch-all taxon Clubionidae, now a shadow of its former self. The clubionoids are apparently similar only in that they have eight eyes arranged in two rows, conical anterior spinnerets that touch and are generally wandering predators that build silken retreats, or sacs, usually on plant terminals, between leaves, under bark...
