Keys to Identify the Subgenus Haemaphysalis
Male
1.
Coxal spurs are crest or ridge-like; salience is very low, which is not bulging posteri-
orly...................[H. indoflava]
Coxal spurs are elongated or sub-triangular...................[2]
2.
Coxa I spur is acute, lanceolate, and approximately 2 times as long as other three coxal
spurs, which are broadly triangular and sub-equal in length...................[H. darjeeling]
Coxa I spur is not 2 times as big as other sub-equal spurs; each coxa is with a prominent
spur, which is widely triangular...................[H. birmaniae]

pointed spurs...................[H. darjeeling]

2.6.1 Haemaphysalis campanulata
This species was first described by Warburton in 1908 from numerous specimens
taken off Chinese dogs in Mongolia collected by Major M.L. Hearn in 1906. This
common dog tick is distinct from other haemaphysalid in that palpal article II is
strongly salient laterally, the posterior margin is flared upward to become “bell-
shaped;” hence the name “campanulata”(
Figure 2.43
).

Capitulum: The capitulum is 0.43 mm in length, base rectangular, dorsally
barely twice as broad as long, punctate all over, and with short blunt cornua.
The palps are 1
1
2
times as long as broad and without any dorsal spines. Article II
is as broad as long and has a strong lateral salience about the middle of its
length with two or three infrainternal long setae. Article III is half as long as the
second and is 1
1
2
times as broad as long. It possesses only a single short blunt
retroverted spur. Hypostome is 4/4, with files of broad teeth, about eight teeth
per file.
Scutum: Scutum is with numerous fine punctations; cervical grooves are deep,
sub-parallel, and slightly convex externally; lateral grooves are beginning about the
anterior third of the body and ending behind the spiracles; festoons are long and
narrow, and well marked. Sexual orifice is broad, between coxa II.
Legs: Coxa are each with a short blunt spur; tarsus IV is very short and thick,
ending in a somewhat abrupt slope, the false articulation about the middle of the
article.
