NERIENE. 
outer side, correlated with four or five minute setigerous cusps on the inner side of the femur of the 
palpus. Eyes of posterior row very unequal, centrals larger, situated on large black tubercles. 
Patella of male palpus without apical cusps. Sternum elongate, produced behind between coxe iy. 
Paracymbium of palpal bulb usually conspicuous, elongate-falciform.

The species here referred to Neriene were recognized as a separate group by 
Keyserling (Spinn. Amer., Therid. ii.), but described under the name of Frontina, 
whose type belongs to quite a different group. 
They are closely allied to Linyphia clathrata, Sund., and if separated from that 
genus the name Neriene must be restored, with WV. clathrata as the type.
