The female has a remarkable, small, modified spine on the tibia of the palp and a characteristic epigyne in which the central plate has a concave anterior and a straight posterior margin. Etymology The species name ‘ securicula ’ meaning hatchet, is a noun in apposition referring to the shape of both the MA and the C.
