Maera danae bears a rather close superficial resemblance to Maera 

 loveni (Bruzelius), a much larger species, which inhabits the Arctic. 

 In M. loveni the defining tooth of the palm of the second gnathopod 

 of the male bears a long, slender spine, and the second joint of the 

 third, fourth, and fifth peraeopods is long and narrow.
