Hamataliwa can be distinguished from the closely related genus Oxyopes by the following characters: female epigynum with a shallow median depression surrounded by a semicircular or U­shaped, heavily sclerotized rim ( Figs. 2 , 7 , 12 , 17 , 22 ); copulatory ducts usually short, spermathecae round or oval ( Figs. 3 , 8 , 13 , 18 , 23 ); embolus of male palp forming a characteristic twist or loop near the base; edge of cymbium with a basal outgrowth, finger­like in lateral view ( Figs. 4–5 , 9–10 , 14–15 , 19–20 , 24–25 ). Copulatory ducts and spermathecae are always wrapped with glue­like materials after copulation ( Figs. 3 , 8 , 13 ), which is not detected in Oxyopes . Description.
