arrangement, the middle ones sometimes in pairs. Size and general 

 appearance like Pedanostethus riparins. The head is only slightly 

 narrowed in front, but more in the male than in the female. The 

 upper eyes are all of the same size and equal distances apart, the 

 lower front pair half as large as the others and close together, but 

 not touching. (Fig. 14, 5.) In the male the metatarsi of the front

legs are slightly curved, and some of the hairs near the middle of 

 the joint are thicker than the others. (Fig. 14, 3.) The male palpi 

 resemble closely those of G. {Tmeticus) hrunneus Em. of the White 

 Mountains, but the tibia has a sharper and more recurved point, 

 (Fig. 14, 2) the tarsal hook though nearly of the same shape has 

 the point less widened and the palpal organ has a long, stiff tube 

 curved in a half circle and extending beyond the end of the tarsus. 

 (Fig. 14, 1 and 2.) The epigynum is like that of hrunneus but longer, 

 projecting farther from the surface of the abdonien (Fig. 14, 4).
