Swartz 1932,p.-39,42,43, and by Bassler and Kellett 
1934,p-484, and the genus was abandoned because 
its type species did not have the characters it 
was supposed to possess. Eucraterellina Wilson 
1935,p-e640 was described with a genotype which 
possessed the characters C. robusta was supposed 
to have. Henningsmoen 1953,p.e260 has retained both 
genera in the Thlipsuridae.]
