Haemaphysalis (Garnhamphysalis) rusae (Ixodoidea: Ixodidae): Identity, Deer and Pig Hosts, and Distribution in Luzon and Mindanao

Description
Summary:Haemaphysalis (Garnhamphysalis) rusae Kohls, previously known only from three male ticks from Mindanao, Philippines, is a seldom collected but probably common parasite of the Philippine deer, Cervus (Rusa) philippinus, and wild pig, Sus celebensis philippensis, in forests of Mindanao and Luzon. A single female taken from a wallaby in Papua New Guinea is presumed to result from an introduction with the Philippine deer. The male, originally briefly described, is redescribed to provide criteria for comparing this species and other members of the subgenus Garnhamphysalis. The female and nymph are described for the first time. The male H. (G.) rusae and H. (G.) calvus Nuttall and Warburton are structurally quite similar, differing only in palpal length: breadth ratio and size of the trochanter IV spur. Females differ more widely in the presence (rusae) or absence (calvus) of a large retrograde spur extending from the posteroventral margin of palpal segment 2. Conversely, qualitative and quantitative structural differences between most Haemaphysalis species are greater in males than in females.
