Note on three aberrant genera of Acridoidea from South and Central America (Orthoptera)

There are several genera of Acridoidea in South and Central America the systematic positions of which are obscure. They have usually been referred by authors to the subfamily Catantopinae and placed into one or other group of genera of this subfamily ; subsequent authors have put them into other groups and thus they are still wandering from one group to another. Recently the opportunity arose to study the genitalia, particularly the phallic complex, of three of these genera. The result of this study does not help, however, to place them definitely into groups, but it does indicate the groups in which they cannot he placed. To create for each of these genera a separate, monogeneric taxon of the status of tribe, subfamily or family, would be premature in the present state of our knowledge of the Acridoidea fauna of South and Central America, which is probably less studied than that of any other region of the 'World. Further study of Acridoidea in this region will doubtless produce many more genera and species which would help to classify them more correctly.Peer reviewe
