The two common species north of Mexico, calix and pratensis , are 
obviously misplaced. Judging by the structure of the genitalia,

in the many species of these small Araneus. Araneus sturmi is the 
type species of the genus A tea. At present it does not seem wise or 
even feasible to fragment the genus Araneus. It would lead to
