In-Depth Information
recorded outside India, and related to darjeeling, are H. capricornis and
H. atherurus. Male of H. capricornis lacks coxal spurs, and has a 4/4 dental for-
mula and short, stout tarsi; thus, it is easily separated from the darjeeling male.
The female of capricornis is unknown. H. atherurus is a small species easily distin-
guished from darjeeling by very short ventral spurs of palpal segment III, different
palpal outlines, dorsointernal and ventrointernal setae each number two, semicircu-
lar spiracular plates, reduced spurs of female coxa, etc.

2.7 Subgenus Kaiseriana
General Characteristics
It consists of 33 species and is the largest subgenus under the genus Haemaphysalis.
Twenty-seven out of 33 Kaiseriana species are Oriental in distribution. Adults are
structurally specialized, some extremely, for parasitizing Artiodactyla; most also
feed on carnivores but other hosts are exceptional. Immatures parasitize small mam-
mals, especially Rodentia. Only immatures of H. longicornis occasionally parasitize
birds. The hallmark of Kaiseriana is a hair-hooking spur extending from the postero-
dorsal margin of adult palpal segment III. In cornigera group males, this spur is sup-
plemented or replaced by a gap in the external surface of the palpus; working as an
efficient hair-grasping gap. The Indian Haemaphysalis under the subgenus
Kaiseriana can be grouped into at least four groups as per the classification of
Hoogstraal and Kim: cornigera group, bispinosa group, aculeate group, and
hystricis group.
