Figure 65. — Stenula incola, new species, male, 2.8 mm., station 42-G-2: a,b,c, uropods 

 1, 2, 3; d, dactyl and part of article 6 of pereopod 2, offset showing fuzzy-button enlarged; 

 e, maxilla 2;/, mandible; g,h,i,j, pereopods 1, 3, 4, 5; k, outer lobe of maxilla 1; /, upper 

 lip; m, telson; n, gnathopod 1; o, mandibular palp. 



lacks telsonic spines and S. bassarginensis has a more distinctly 

 subchelate gnathopod 1 because article 6 is narrowed proximally, 

 thus providing a discrete defining corner to the distally expanded 

 palmar area. Stenula incola has the long mandibular palp similar 

 to that of S. beringiensis (Gurjanova, see 1951) but it is poorly 

 setose, the telson lacks spines and article 6 of gnathopod 1 is more 

 densely and irregularly setose than in &. beringiensis. Stenula ratmanovi 

 (Gurjanova, see 1951) has a short mandibular palp and a very large 

 spine defining the palm of gnathopod 1.- Stenula latipes (Chevreux 

 and Fage, 1925) is closely related to S. incola but the mandibular 

 palp is very short, the male second gnathopod has article 6 more 

 elongated and the palm regularly oblique, serrated and shorter
