Family OXYCEPHALIDAE 



Bovallius, 1890. 

 Stephensen, 1925 a, p. 182. 

 Spandl, 1927, p. 178. 



Stephensen makes Dorycephalus synonymous with Leptocotis ; he retains Rhabdosoma 

 (Xiphocephalus) within the family, and also Simorhynchotus , though the latter, together 

 with Metalycaea and Glossocephalns, form a transition to the Lycaeidae as regards the 

 shape of the head. Spandl, without giving critical reasons, excludes Simorhynchotus from 

 this family and assigns it to the Lycaeidae.
