ResumoHaemaphysalis species and subspecies, although frequently distinguished from each other by only unspectacular combinations of characters, seldom display sufficient morphological variability to confuse their identity. Among the African haemaphysalid fauna, the commonest species, the Yellow Dog-Tick, H. leachii (Audouin, 1827), a vector of both human and canine diseases (Hoogstraal 1956), is a notable exception to the above generalization. Contemporary workers feel certain that this species is represented by at least 2 subspecies in Africa. The second form, referred to provisionally as H. leachii muhsami Santos Dias, 1954, requires further morphological and biological study and taxonomic investigation to establish whether this is the earliest name available for this form. At any rate, numerous populations of H. 1. leachii and H. 1. muhsami are difficult to separate from each other and more definite criteria than those already existing need to be sought. A third form, H. leachii indica Warburton, 1910, occurs in the Oriental Region. The original specimens of H. leachii, described from Egypt, are now lost (M. Andre, correspondence). Since large series from Egyptian populations are available, it is desirable to describe these carefully as a basic reference for further studies and to select a neotype (see below) to represent this subspecies. Concurrently, representative Egyptian material is being deposited in numerous important tick collections.
