Mahale can beregarded as a “forest-island” in the midst of the Miombo woodland whichextends over a vast area of western Tanzania and eastern Zaire (Congo).Surveys targeting blood sucking flies associated with wild chimpanzeeshave been carried out at the park, during the November-December rainyseason of 1995, 1996 and 2004. A total of 14 species belonging to 4genera of tabanid flies have been collected. In addition, the tabanid flyspecimens have been stored to be examined in the Center for AfricanStudies at Kyoto University, I found 3 genera and 3 species to be newlyrecorded and have been added to the list. Collected tabanid flies aremainly Haematopota species. The predominant species is Haematopotafasciatapex. From this research, Haematopota nigripennis, H. unicolorand H. theobaldi are newly recorded in Tanzania. Two tsetse species,Glossina morsitans morsitans and G. longipennis, have been collected inthe vicinity of chimpanzee populations. The blood meals of G. longipennisare determined to be primate origin in high rate by the ELISA method.Two genera and 9 species of stomoxyn biting flies have been collected aswell. Those flies are captured mainly at the grassland sites in the short217
