Florida Entomologist, Vol. 87, No. 4, 2004
"A dichotomous key is presented to aid in the identification of the adult stage of the 71 grasshopper species known to occur in Florida. Reflecting recent research one subspecies, Schistocerca alutacea rubiginosa (Scudder), has been elevated to species status Schistocerca rubiginosa (Harris) in this key."

Song, H.J. 2004. Revision of the Alutacea Group of Genus Schistocerca (Orthoptera: Acrididae: Cyrtacanthacridinae). Annals of the Entomological Society of America 97(3): 420-436.

ABSTRACT The North American Alutacea Group of the genus Schistocerca is revised based on phylogenetic analysis and morphological comparison. Phylogenetic analysis suggests that Schistocerca alutacea sensu Dirsh is paraphyletic because S. alutacea albolineata sensu Dirsh is sister to S. obscura. Here, I recognize the monophyletic Alutacea Group consisting of six species: S.

The North American Grasshoppers, volume I, Acrididae, Gomphocerinae and Acridinae
By Daniel Otte
Harvard, 1981
This is a very thorough treatment of the Slant-face Grasshoppers. It is full of information on behavior, has descriptions and maps of all species, as well as high quality illustrations of nearly all. It is extremely useful as an identification guide, as well as for learning about these fascinating insects. It covers all of North America from Panama northward. The treatment is still nearly up to date, with little having changed since it was published. I believe it is out of print now, but I find it still occasionally available. Hopefully it will be reprinted.
