Schizomids are commonly known as 'short-tailed’ whip-scorpions, because they have a short flagellum. There are approximately 258 described species. 

Schizomida are closely related to uropygids, having both:

What sets them apart from the other arachnid orders is the unique structure of the surface of the prosoma, which is divided into segments.
