November (summer and fall). The pattern from June and July was like that in
Pakistan but sufficient number of females was present in August and September.
Related Species
The species montgomeryi is closely related with H. parva morphologically. The spe-
cies H. parva has not been recorded from India. Immature of parva and montgomer-
yi palpi II form large unique posteroventral spurs. The adult palpi are campanulate
in male and broadly campanulate in female of parva while elongately campanulate
in montgomeryi. The adult parva palpal segment III, ventral spur and coxal spurs are
moderately large; however, in montgomeryi segment III ventral spur is unusually
elongate, more in female. Coxal and trochantal spurs are extraordinarily large in
male and moderate in female. Host adaptive structures are mild or reduced in adult
parva and extremely developed in adult montgomeryi. Such structures are well
developed in immatures of both species. Close phylogenetic relationship of these
two species is revealed by similarity of distinctive female external genitalia.
2.9.2 Haemaphysalis obesa
This species was described for the first time by Larrousse in 1925 from Vietnam
with a presumed host to be a barking deer ( Figure 2.114 ).
