ABSTRACT

Ultrastructural features of the gastric caeca of Odontosciara sp. are reported. The species has 4 lateral caeca connected with the anterior midgut at the level of the foregut junction. The epithelial cell features indicate protein synthesis, digested material absorption from the lumen and haemolymph material absorption. Those functions, however, do not seem to be very intense.
