Abstract
The internal structure of the proventriculus of 17 species from 12 gryllacridid genera is described using light and scanning electron microscopy and is discussed in relation to its use as a taxonomic character. Structural differences were sufficient at 60 to 200 x to separate genera and species. Correlations between proventricular structure and food type are briefly discussed.
