It may be small in stature, but mighty big mouth parts make Metaltella simoni look quite fierce up close.
The dark brown abdomen and lighter, even orange-brown carapace give Metaltella simoni a two-toned appearance. The color and sheen on the abdomen is somewhat similar to that seen on a Brown Recluse, but Metaltella simoni lacks the trademark 'violin' on the head area. Large, black chelicera on the darkened face are helpful in dispatching an insect meal. Males have a large knob, or sphere, at the end of each pedipalp. Legs are brown, similar to the shade of the carapace.
This tiny spider is often found indoors, but its natural habitat is on the ground among rocks, sticks, and other things where smaller insects are found.

Size (Adult; Length): 6mm to 10mm (0.23in to 0.39in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Legs: Spiders have four pairs of legs and these are attached to the cephalothorax.
Pedipalps: Small appendages near the mouth used as taste and smell organs.
Cephalothorax: Contains eyes, head, mouthparts, and legs.
Abdomen: Contains various organs related to digestion, reproduction, and web-making.
