In-Depth Information
Larva (
Figures 2.68 and 2.69
)
Redescribed
Larva is small and is about 0.7
0.9 mm in length.
Capitulum: The cornua are also very short, broadly triangular, and about half
the length of the basis capitulum. Palps are very loosely arranged, palpal segment
II is with no or very less salience. One long infrainternal seta is present on ven-
trointernal side of the palpal segment II. Palpal segment III shows no spur on dorsal
side but a short, broadly triangular spur on ventral side, reaching up to anterior of
the palpal segment II. Hypostome is short, about 0.08 mm in length, with 2/2 dental
formula and with six or seven denticles per file.
Legs: Coxa I shows small, triangular spur, just reaching to anterior of the coxa
II. Coxa II and III show no spur or crest-like structure. Trochanters also show no
spur or crest-like structure.
Immature stages: Mouse deer, crested porcupine, langur monkey, buffalo, rat,
bonnet monkey, and birds like babbler, bulbul, Myna, Indian robin, and crow
pheasant.
Adults: Mouse deer, man, monkey, bird species, cow, leopard, mongoose.

Disease Relationship
No KFD virus isolation has been reported from this species of ticks.
2.7.6 Haemaphysalis davisi
Hoogstraal et al. first described this species in 1970 from tick samples taken from
domestic and wild mammals and in vegetations of Arunachal Pradesh and Sikkim
in India and from Burma. This species is named after Dr. Gordon E. Davis who
collected most of the material recorded from Burma (

).

Length from palpal apices to posterior scutal margin is 2.55
2.93 mm (average
2.80), breadth 1.58
1.88 mm.
Capitulum: Basis capitulum is dorsally approximately 1.5 times as broad as
long; external margins essentially straight (slightly indented at mid-length); cor-
nua are broadly triangular, approximately one-third as long as the base of basis
capitulum. Palpi are moderately salient posteriorly, combined breadth is approxi-
mately 1.4 times that of basis capitulum. Hypostome is slightly shorter than palpi.
Dental formula is chiefly 6/6 (7/7 anteriorly), with seven to eleven denticles in
afile.
