Stenocotidae 
Baker (1923) considered Koebelia to be intermediate be- 
tween Ulopa Fall, and Paropia Germ, on the one hand, and 
Stenocotis Stal on the other. For reasons previously given, 
(Evans, 1939), there would seem to be no justification for 
placing Koebelia californica Baker in a separate family, 
when it is essentially a Stenocotid.
