Distinguished from other wolf by long leg perpendicular to leg axis (most other wolf spiders have shorter spines parallel to leg surface). Hind legs particularly long, making spines on this pair easiest to observe. Distinguished from other Pardosa only by microscopic examination of : female structure or male . arrangement typical of wolf spiders: four small in two rows, two large , and set well back on .
