dorsal as well as huge and pointed spur, protruding over the palpal segment
II reaching to base of palpal segment I on ventral side. Dental formula is 4/4, con-
taining eight or nine denticles in each row.
Legs: Coxa I as in male shows an elongated, pointed sharp spur, extending along
half of the coxa II. Coxa II to IV show no spur but a crest-like outgrowth toward
the posterior side. Trochanter I shows a spatulate-shaped spur but on trochanters II
to IV there are a crest-like outgrowth like that of the coxa.

The average length is about 1 mm.
Capitulum: Cornua are about the same length of that of basis capitulum.
Basis capitulum shows few punctations. Palpal segment II shows very less
salience and no spur on either side. Two infrainternal setae are present on ven-
trointernal side of the palpal segment II. Palpal segment III shows no spur on
dorsal side but a small, triangular, pointed spur is present on ventral side extend-
ing to half of palpal segment II. Dental formula is 2/2, containing eight or nine
denticles in each row.
Legs: Coxa I has a big, bluntly pointed triangular spur, extending up to half of
coxa II. Coxa II and III show small spur-like outgrowths. Coxa IV shows a crest-
like structure. Trochanter I shows a small spur, while trochanters II to IV show
only crest-like outgrowths.

It is about 1 mm in length.
Capitulum: Cornua are very short and with triangular pointed apices, about half
the length of basis capitulum. Palps are quite well spaced or widely arranged.
Palpal segment II is with one infrainternal seta and shows very low salience. Palpal
segment III on dorsal side shows no spur but on ventral side shows a short, triangu-
lar spur extending just beyond the intersegmental margin between segment II and
III. Dental formula is 2/2, with six denticles in each row.
Legs: Coxa I shows a small, triangular spur extending just anterior to coxa II,
while coxa II and III show no spur but a crest-like structure. Trochanters show no
spur or crest-like structure.
Life History of H. cuspidata
11
Bhat et al. in 1974 studied the life history of this species. The minimum duration
of a total life cycle under the laboratory condition was observed to be about
120
100% RH and at room temperature between 17 and 27
C.
The maximum life span of adults was 317 days. Most of the hungry (questing)
adults attached themselves to the experimental hosts within 48 h after putting them
on the respective hosts. Copulating pairs were observed on the fifth day after
784 days at 90
