The present study characterized morphologically Trypanosome (Schizotrypanum) vespertilionis Battaglia, 1904 isolated from insectivorous bats captured in Dandara caves was appeared for the first time record in Qena province this parasite was had a zoonotic importance so that the present work aims to describe the different stages by light microscopy. Of twenty-five insectivorous bats examined, three bats were found infected with T. (S) vespertilionis with an average infection rate of 8.5%. Also, eleven bats (48%) were infested by ticks Ixodida sp. Most stages of T. (S.) vespertilionis in the blood were trypomastigote stages, at the same time spheromastigots, epimastigote and amastigotes stages with two shapes slender and broad. Small size and peculiar morphological features of the blood stream trypomastigotes, the
more remarkable one being the large round kinetoplast. A posterior body end o appeared as a bulge or small stretch. The free flagellum was fairly long, the undulating membrane was well developed, tightly surrounding the body and had only 2-4 shallow undulation.
