There are 15 Nearctic species ofKratochviliana, of which 10 species are described herein as new. These are:C. (Kratochviliana)robustan. sp.,C. (K.)incertan. sp.,C. (K.)stipitisn. sp.,C. (K.)hirsutiventrisn. sp.,C. (K.)walleyin. sp.,C. (K.)protolithocolletidisn. sp.,C. (K.)millerin. sp.,C. (K.)alutan. sp.,C. (K.)coptodiscaen. sp., andC. (K.)cuspidigastern. sp. Relationships and distribution of species-groups in North America and Europe are discussed. Keys to subgenera and species and host records are included.
