Family: Araneidae
Araneus
himalayaensis Tikader, 1975
Family: Araneidae
Size: 8-10 mm
Distribution: India, China
Habitat: Moist Deciduous forests.
This is an orb web builder. They rest to the side of the web in
a dull coloured silken retreat which may be spun up between the
leaves of shrubs. The tips their front legs can often be seen sticking
out of the retreat, in contact with a signal thread which runs directly
to the centre of the web.
Argiope
anasuja Thorell, 1887
Family: Araneidae
Size: Female: 8-12 mm; Male: 3.5-4.5 mm
Distribution: India, Pakistan, Sri Lanka, Maldives
Habitat: Moist Deciduous forests in the sunny parts
These spiders construct vertical webs in shrubby plants and decorate
their webs with stabilimenta. They usually rest in a head down position
on the web. As one approaches the web, they hold their position
until the last moment before slipping round in a flash to hide on
the other side of the stabilimentum. Argiope is spread across tropics
to temperate regions.
Cyclosa
bifida (Doleschall, 1859)
Family: Araneidae
Size:
Distribution: India: Kerala, Sikkim, Meghalaya;
Sri Lanka, New Guinea, Malaysia
Habitat: Moist Deciduous forests
Spiders of this species spin vertical orb webs in the vegetation,
usually found at height of about one meter above the ground. Across
the diameter of the web, a stabilimentum is present formed of pieces
of debris and egg sacs. The spider sits at the centre of the orb
among debris, the cryptic colouration and its habit of hiding among
the debris in the stabilmentum makes the species inconspicuous.
The genus Cyclosa occurs world wide, ranging from the temperate
regions to the tropics.
Cyrtophora
moluccensis (Doleschall, 1857)
Family: Araneidae
Size: 8-9 mm
Distribution: India, Singapore, Malaysia, Indonesia,
Japan, Australia, Papua New Guinea
Habitat: Gardens
These spiders build more or less horizontal orbs in shrubs and
other plants. A typical web can be some 30 cm in diameter and is
held in position by the combination of a substantial tangle of silken
threads attached to the shrub, both above and below the orb. Communal
web consists of the webs of numerous familyes. These spiders rest
on a platform near the end of the orb web. There is a special mark
on the dorsal side of the abdomen. Medium sized spiders. Cyrtophora
is widespread throughout the tropics and subtropics with
Eriovixia
laglaisei (Simon, 1877)
Family: Araneidae
Size: 5-9 mm
Distribution: India: Kerala, Tamil Nadu; Singapore,
Philippines, Myanmar, Sri Lanka, Papua New Guinea
Habitat: Moist Deciduous forests, Urban localities
This is one of the commonest spiders in Kerala and most people
might have seen their webs in the backyards. The spider has a flattish
abdomen covered with off white hairs. The posterior end of abdomen
has tail like extension. It spins vertical orb webs and is usually
found on plants, shrubs even on those in gardens. The under surface
of abdomen has a black median patch bordered by white lateral patches.
Species exhibit much variation in colour, some are white and some
brownish. In its typical resting posture legs are pulled in around
the abdomen and carapace thus forming a circular outline. Often
near the spider there are some flecks of white silks. Eriowixia
ranges from Africa to Papua New Guinea.
Gasteracantha
geminata (Fabricius, 1798)
Family: Araneidae
Size: 7.7mm
Distribution: India: Kerala, Karnataka, Tamil Nadu;
Sri Lanka
Habitat: Moist Deciduous forests
This is one of the commonest spiders in Kerala, observed in almost
all the districts of Kerala. They are characterized by the presence
of hard shell like flattish bodies; and black and white transverse
bands on the abdomen. The colouration and shell like body are thought
to be providing protection to the spider. The abdomen has three
pairs of long stout lateral spines or projections, these lateral
spines are actually modified simple spines. Abdomen is also characterized
by number of pit like depressions or sigilla. Typically these pits
or imprints are dark coloured. They construct vertical orb webs,
often in open spaces between the branches of tall shrubs. In its
typical posture the front portion of abdomen covers the thoracic
portion of cephalothorax and only the cephalic portion is visible
from above. The genus Gasteracantha is widespread in the tropics.
Neoscona
rumpfi (Thorell, 1878)
Family: Araneidae
Size: 7-9 mm
Distribution: Cosmopolitan.
Habitat: Gardens
These spiders rest on a platform near the end of the orb web. There
is a special mark on the dorsal side of the abdomen. Medium sized
spiders.
Parawixia
dehaani (Doleschall, 1859)
Family: Araneidae
Size: 18-20 mm
Distribution: India, Singapore, Indonesia, Myanmar,
Papua New Guinea, Japan.
Habitat: Gardens, waste lands
The only one species of this genus is P. dehaani. The female is
essentially a large, dark brown spider but with variable patterns
on the abdomen. The most noticeable characteristic in the field
is the triangular area having corners at the sharp "thorns".
The female spins a fairly large, loosely woven orb in a space, low
down in the vegetation. The spider hides underneath a leaf in the
vegetation nearby during the day. When disturbed, it will drop to
the ground and "play dead", with the legs retracted and
close to the body. This spider is distributed throughout the tropics.
Family: Clubionidae
Clubiona
drassodes O. P.-Cambridge, 1874
Family: Clubionidae
Size: 5-7mm
Distribution: Cosmopolitan
Habitat: Foliage in garden.
The carapace is elongated and oval with a creamy white colour.
There is a dagger shaped mark on the abdomen. The posterior lateral
eyes lie adjacent to the anterior laterals and form a six eyed recurved
pattern. The first pair of legs is not larger than the others unlike
Cheiracanthium species. These spiders live in folded leaves.
Family: Eresidae
Stegodyphus
sarasinorum Karsch, 1891
Family: Eresidae
Size: 7-10 mm
Distribution: Kerala, Tamil Nadu, Maharashtra,
West Bengal, Punjab, Orissa; Sri Lanka, Nepal
Habitat: Thorny bushes
This is colonial spider, building large sac like webs. Each nest
contains many individuals including young ones. Members of the colony
cooperate with each other in building the web, its repair, prey
capture. The sac is formed of a sticky silk and any bee or fly coming
into contact with these can never escape. The sac or nest has a
number of holes on its surface, when disturbed spiders immediately
withdrew into the holes of the nest. As the younger generation grows
up, the older member's die or some of them go off to found another
colony. Though not common in Kerala it is found central Kerala and
abundantly in dry areas of the state.
Family: Hersilidae
Hersilia
savignyi Lucas, 1836
Family: Hersilidae
Size: 8-10mm
Distribution: Kerala, Karnataka, Maharashtra, Gujarat,
West Bengal, Myanmar, Philippines, Sri Lanka
Habitat: Tree trunks
Popularly called two tailed spider, this is common spider in southern
India. It lives on tree trunks of large tress and also common on
the trunk of coconut palm. Its colour closely matches that of tree
trunks in which it lives. It feeds on moths, ants, and other smaller
spiders. Cocoon is generally laid in the holes crevices of tress.
It can be easily identified by its long spinnerets.
Family: Linyphiidae
Linyphia
urbasae Tikader, 1970
Family: Linyphiidae
Size: 5-7mm
Distribution: India
Habitat: Jungle foliage
These are large Linyphid spiders with easily seen, sizeable webs
constructed on shrubs, etc. The web consists of a more or less horizontal
sheet, often 15-30 cm across, held in position by masses of threads
attached to the vegetation above the below the sheet. These spiders
have peculiar abdominal patterns. Typically, running the length
of the abdomen there is a white chocolate brown stripes which is
bounded on each side by lighter stripes. Sometimes egg sacs are
carried in mouth.

These spiders build sheet webs with a silken funnel retreat in
short grasses. Carapace is longer than broad with the cephalic part
pale and with broad pale submarginal bands and dark streaks radiating
from the fovea. The abdomen is elongate and oval. Both the brown
cardiac mark and the five pairs of adjacent light spots that follow
are all edged with a dark olive brown border. The superior spinnerets
are diverging. Legs are vaguely annulated and dark olive brown in
