The pereon and pleon are approximately equal in length, their height 

 in females identical while in males the pereon is not quite half the height 

 of the pleon. somite I of the pereon in males is equal in length to the 

 next two somites together. 



The 2nd segment of pereopods I and II is generally shorter than the 

 distal segments together. The 2nd segment of pereopods V and VI is 

 highly broadened but not operculiform. The anterior margin of the 5th 

 and 6th segments of pereopods VI is denticulate. 



The telson is shorter than the last urosomite. 



Type species: Lycaeopsis themistoides Claus, 1879

Length of adult males and females up to 5 mm. 



The head is oval in shape, its height much more than its length. 

 Somite I of the pereon in males is equal in length to the next two somites 

 together; in females these somites differ less in length. 



The 1st segment of the flagellum of antennae I is thicker in males, 

 with a pointed apex; the distal segments are articulated with it in the 

 upper part at a distance of half the length of the segment from the apex; 

 the apical segment is very thin. 



The 2nd segment of pereopods I is weakly broadened; the 3rd-5th 

 segments are short; the claw is almost half the length of the 6th segment; 

 the 3rd-7th segments together are longer than the 2nd segment. The 2nd 

 segment of pereopods II is almost linear and straight, and slightly shorter
