Remarks. — Kroyeria gemursa can be separated from all known 

 members of the genus by the sclerotized area at the end of the abdomen. 

 It can be further distinguished from all species except K. dispar by 

 the lateral swellings on the labrum. It can be separated from K. 

 dispar by the presence of the prominent spines on the intercoxal plates 

 of legs 2-4. 



Habitat: Gill filaments. 



The name gemursa, from Latin, meaning "swelling between toes," 

 refers to sclerotization on abdomen.
