This species and Jelskia tenuis are easily distinguished from other mem- 

 bers of this genus by their dark color and elongated legs; while velox is 

 distmguished from tenuis by the hairs on the patella and tibia of the pal- 

 pus, and by the position of the spines on the tarsus of the palpus, these 

 being placed side by side in velox and one behind the other in tenuis.
