With regard to the number of the cirrals this species is most 

 closely related to St. diadema, but well separated from this by the 

 formation of Cd, by the shortness of the cirri, when compared with 

 the arms (the latter are at least twice as long as the cirri) and by the 

 large and many prominences on the ossicles of the arm-bases. By 

 this the new species approaches Daidalometra (hana), a genus properly 

 distinguished from Stenometra only by a smaller number of arms. The 

 above-described species is to a certain extent a transition-form between 

 the above-mentioned genera.
