These spiders are described as

The cephalothorax is squared off at the front, and the fovea or central pit runs lengthways. Eight eyes in two row of 4, the back row wider, the front row slightly upcurved. The fairly large and longish jaws have two or three teeth on the outside, two on the inside. The abdomen is oval, or elongated. They are common in inland regions belonging to the superfamily Lycosoidea, somewhat resembling wolf spiders but without the distinctive Lycosid eye pattern.

Cephalothorax is the fused head and thorax of spiders and other chelicerate arthropods (chelicerates being a group of arthropods whose characteristics include a body divided into a cephalothorax and abdomen).

Miturgidae is a family of araneomorph spiders with species found around the world.

The Araneomorphae are an infraorder of spiders. They are distinguishable by chelicerae that point diagonally forward and cross in a pinching action, in contrast to the Mygalomorphae, where they point straight down. Araneomorphs comprise the vast majority of living spiders.
