B. First elongated pair of legs with long spines only on the last joint. 

 Inner lobe of copulator}' organs with the proximal process either a little 

 thicker and at most a little shorter or, most frequently, much thicker 

 and from somewhat to very much longer than the terminal process. 



a. Spine-shaped and terminal processes at least about half as long as 

 the pro.ximal process, the distal outer margin of which is even, 

 not serrated. 



a. Proximal process slender, acute, diaphanous, not longer, or even 

 a little shorter, than the terminal process, which considerably over- 

 reaches the spine-shaped process. (Eyes in both sexes somewhat 

 smaller than in A^. microps) N. atlantica n. sp. 



|5. Proximal process rather thick, obtuse, generally opaque, con- 

 siderably longer than the terminal process which is shorter than 

 the spine-shaped process N. microps G. O. S. 



b. Spine-shaped and terminal processes several times shorter than the 

 proximal process, the outer margin of which is serrated towards 

 the end. 



a. Lower part of the eyes not smaller than the upper part. Copulatory 

 organs with the terminal process short, but yet longer than the 

 basal diameter of the proximal process N. gracilis n. sjj. 



'^j. Lower part of the eyes much smaller than the upper part. 

 Copulatory organs with the terminal process very short, at most 

 about as long as the basal diameter of the proximal process . A^. tcnella G. O. S.
