Diagnosis of the Indian population
(Data based on
4 specimens
): Size about 160 × 40 μm in protargol preparations; shape elliptical with body ends rounded, dorsoventrally flattened. Nuclear apparatus composed of on average seven macronuclear nodules, about 10 × 7 μm in size mostly arranged in a row slightly left of mid-body and 2-4 micronuclei attached or near to macronuclear nodules. Cortex flexible. Contractile vacuole in mid-body near left cell margin. Buccal cavity wide. Adoral zone occupies about 32% of body length, composed of 47 membranelles on average. Cirri, on average, composed of three frontal, one buccal, two frontoterminal, 19 midventral cirral pairs, two pretransverse ventral cirri, eight transverse cirri, one left and one right marginal cirral rows composed of 46 and 44 cirri, respectively. Caudal cirri absent. Six dorsal kinety rows.

Anteholosticha monilata
Indian
population.
A-D.
Specimens from live, showing body shape, position of contractile vacuole, nuclear apparatus arranged in a row, and ciliature. Inset in 9B) shows the lateral view of a specimen.
E-G.
Specimens showing ciliature on the ventral surface. Arrowhead in (F) points to the buccal cirrus.
H.

Occurrence and ecology
:
The
species
Anteholosticha monilata
is rather common in freshwater though rare in terrestrial habitats.
It
has been recorded from
Austria, Czechoslovakia, France, Germany, Moldavia, Norway, Spain, Belgium, Cameroon
, USA (for further details, refer
Berger (2006)
.
The
present study reports its presence from soil samples collected from the
Parambikulam Wildlife Sanctuary
,
Sangam Range
,
Palakkad district
,
Western Ghats
(
10°26’29.2’’N
76°46’29.3’’E
),
India
. It feeds on flagellates, bacteria, amoeba, diatoms, and small ciliates.
