This paper is a revision of the New World members of genus Crossocerus (i.e. taxa of North, Central, & South America...or equivalently the "Nearctic & Neotropical" biogeographical realms).

The revision is written mainly in French, although the key to species is given in English (see pp. 9-28). For most of the 70 taxa treated the discussions are relatively brief...helpful info is provided but detailed descriptions are mostly lacking (except for the newly described taxa: 28 sp. nov. and 2 ssp. nov.).

To search out literature with more detailed info on previously described taxa of interest, one can make use of the 7 pages of catalog listings for Crossocerus from Krombein et. al.(1)(1979)...and if more detail is desired...with the incredibly rich catalog/"condensed bibliography"" for all world species of Crossocerus in the PDF here from the online Catalog of Sphecidae(2) by Wojciech Pulawski.

As a starting point, the paper Fox(1885) contains descriptions of many of the previously described taxa...though often under synonymized earlier names.
