Besides the type species, lmpalaia tuberculata Monnig, 1924, there are 2 valid species, viz., I. nudicollis Monnig, 1931and I. okapiae (Van den Berghe, 1937). I. tuberculata longispiculata (Wetzel & Fortmeyer, 1960), I. somaliensis (Crovieri, 1929) and I. aegyptiaca Soliman, 1956 are synonymous with I. tuberculata. I. taurotragi (LeRoux, 1936) appears to be an aberrant form of/. nudicollis. A parasite/host checklist is included.en© 1977 ARC – Onderstepoort and Faculty of Veterinary Science, University of Pretoria (original). © 2016 University of Pretoria.
