Tigrosa helluo is a species of spider in the family Lycosidae. It was formerly known as Hogna helluo. It is found in the Canada, the United States and Mexico.[1]
The carapace of T. helluo is
characterized by a clearly defined medial stripe from a point between
the middle pair of eyes nearly to the point at which the carapace joins
the abdomen. The abdomen has a broader light stripe with a darker narrow
and tapering form like the head of a lance or a stone arrow point. The
underside of the cephalothorax is solid black, but the underside of the
abdomen may be spotted with lighter colored patches. This species does
not dig tunnels but may create shelters under rocks and similar natural
features
