Remarks
Several species of Neoscona and Araneus that are considered "barn spiders" can only be identified by examination of the carapace groove (fovea). Neoscona have a longitudinal groove on the carapace (parallel with the long axis of the body), whereas Araneus have angular (transverse) grooves. However, an apparent problem is that in Araneus the groove may appear as little more than a dimple, making it difficult to discern.

Araneus
  

Some of the smaller species in this genus were revised and described by Levi in 1973, pp. 473-552 - Small orb-weavers of the genus Araneus north of Mexico (Araneae, Araneidae).
