| Resumo: |
The aim of this paper is to report the morphology and distribution of microspines in diplopods pylorus, as these are important structures present along the alimentary tract of arthropods. The morphology of the internal surface of the pylorus of Pseudonannolene tricolor Brolemann, 1901 and Rhinocricus padbergi Verhoeff, 1938 was analyzed by SEM. Pseudonannolene tricolor presents two morphologically distinct pyloric regions: anterior and posterior. The first region is characterized by the presence of thin microspines that increase in number and size towards the posterior portion; the second region presents smaller and triangular-shaped microspines distributed throughout small plates. The pylorus of R. padbergi does not present differentiated regions; the anterior portion is characterized by microspines grouped in plates that decrease in number and increase in size towards the ileum.
