DIAGRAM OF GENERAL RELATIONSHIPS BETWEEN LEPTUROIDINE GENERA 

 AND "species groups" OF LUDIUS 



Species above the broken transverse line have the nasale single-pointed; 

 species below this line have the nasale triple-pointed, except in Limonins pilosus 

 (Leske). Genera in parentheses have the urogomphi simple; all others have the 

 urogomphi bifid. The spacing suggests the degree of relationship, and possible 

 annectant groups are indicated by connecting lines.
