Family Lycosidae, Group Lycoseae, Genus Lycosa Latr. 



L. clarki sp. n. 



The Cephalothorax is orange yellow, with white downlying hair, 

 darkening; into brown in the well marked fovea separating the cephalic and 

 thoracic parts, round the margin of the thoracic part, and in a row of rather 

 large spots a little above the margin. The sides of the Eyespace are black, 

 but not the middle part. The Mandibles are yellow brown with short white 

 hairs. The Maxillae are yellow with long upstanding brown hair. Lip yellow 

 brown. Sternum and Coxae bright yellow with brown upstanding hair, 

 the other joints of the Legs canary yellow with white hair and faint grey rings, 

 the hair darkening to grey on the tarsal joints. 



The Abdomen is yellow on the upper side, mottled with rather large 

 brown spots and short downlying white hairs, underneath pale yellow covered 

 with rows of rather coarse downlying white hair. 



The Cephalothorax is rather broad in front, rounded at the sides with a 

 short thin longitudinal fovea at the top of the rear slope. The front row of 

 Eyes are straight, the median pair larger than the side, half the diameter of the 

 latter away from them, and twice that distance from one another. They are 

 their own diameter from the margin of the Clypeus, and two-thirds that 

 distance from the eyes of the second row. The latter are nearly twice the 

 diameter of the front median, and their own diameter apart. They are the 

 same distance from the rear row, which are rather smaller, and three of their 

 diameters apart. 



The Mandibles are as long as the front of the Cephalothorax is broad. 

 They are sparsely covered with fine hairs, thickest at the outer margin. The 

 fangs are long, not much curved. On the inner margin of the falx sheath 

 are two equal teeth followed by one small. 



The Lip is as broad as long hollowed in front, about half the length of 

 the Maxillae which are broadest in front where they nearly meet. 



The Sternum is convex ovate pointed at the rear end, where the Coxae do 

 not quite meet. There is also a space between the second and third pairs. 

 It is moderately covered with downlying fine hair and upstanding bristles at 

 the sides. 



The Legs are of moderate length and tapered to a fine point at the tarsus, 

 there are no scopulae and the front two pairs have only a few short spines on 

 the tibia. The two rear pairs rather long spines. The superior claws are 

 pectinated at the basal end, the lower smooth.
