 The genus Oncopodura was erected in 1905 for a species 

 {0. hamata) found in the Sundurlu Cave in the Crimea, in 

 Southern Kussia. It was placed in a separate subfamily 

 (Oncopodurina?), and this arrangement was used in the syste- 

 matic works of Wahlgren (1906) and Borner (1906). Ex •( pfc 

 for the original [Japfi', tiie author has not seen any other 

 records of Oncopodura, and Dr. Carl informed him (m lit. 

 Nov. 1910) that he did not know of any other published 

 records.
