Overview
Taken from: A Revision of the North American Ammophila (hymenoptera, Sphecidae). Arnold S. E. Menke, 1965.


Ammophila (Ammophila) evansi Menke
(Fig. 121)
Ammophila evansi Menke, 1964. Acta Hymenopterologica 2:20. Holotype male, Colebrook, Connecticut (Museum of Comparative Zoology, Cambridge).
Ammophila or Sphex arvensis of authors, not Dahlbom.

The black, erect head and mesosomal hair and the elongate collar are diagnostic features of evansi.

Fernald (1934) included evansi and several other species under Dahlbom’s name. Murray (1938) restricted the name arvensis to the species described as new by Menke (1964a). Menke (1964b) demonstrated that arvensis was an Old World species.

Ammophila evansi occurs from the eastern Great Plains to the Atlantic Coast. I have seen it from Ontario, Quebec, and Nova Scotia in Canada.



Ammophila azteca Group
Diagnosis. The azteca group characteristics are essentially the same as for the urnaria group except that the preepisternal sulcus is long, ending in the ventral region.
Included species. Ammophila acuta (Fernald), azteca Cameron, breviceps Smith, californica Menke, evansi Menke, harti (Fernald), karenae Menke, mediata Cresson, peckhami (Fernald), pruinosa Cresson, regina Menke, strenua Cresson and varipes Cresson.
Discussion. The azteca group is in need of a thorough study since the status of several species is in doubt, For example, “Ammophila pruinosa” is now known to consist of several closely related and undescribed species. The same situation may exist in Ammophila strenua and azteca.
Erect hair color, mesopleural patterns of appressed silver hair, color, and the configuration of the pronotal collar are useful for species discrimination in this group, The male genitalia are distinct in only half of the species; e, g., acute, californica, karenae, peckhami, pruinosa and regina (see figs, 115-120). The aedeagi of the remaining species are similar to that of Ammophila urnaria in the urnaria group (figs. 128-129).
The azteca group is represented throughout North America, The range of A. mediate and azteca extends past the Arctic Circle in western Canada. The group occurs in Mexico and specimens of an undescribed species belonging to the azteca group have been seen from the Andes of South America.
