Remarks. Leptognathia has suffered both the greatest accretion and, latterly, attrition of all tanaidomorphan genera as species have been added to it or removed in subsequent revisions (e.g. Hansen 1913; Lang 1968; Bird & Holdich 1984; Sieg 1986a; and Larsen & Shimomura 2007). Further revision and contraction is anticipated.
