Sparassidae spiders are often confused with
the family Theraphosidae (Baboon spiders).
The latter are more bulky and very hairy without the typical ventral markings.
Sparassids can be confused with spiders of the Ctenidae and Pisauridae families.
Sparassids are commonly known as huntsman spiders and large wandering crab
spiders. Afrikaans names are grootdwaalkrapspinnekop and jagspinnekop.
Genera indigenous to southern Africa
Arandisa
Monotypic in
that the genus contains only one species, Arandisa deserticola, a
Namibian endemic. 10.8mm. |
|
Carparachne (wheeling spider)
A
Namibian
endemic, which is psammophilous, occurring on sand dunes in arid areas very
similar to Leucorchestris. Carparachne, known as the wheeling spider
due to its habit of folding its legs and cart wheeling down sand dunes to
escape predatory spider hunting wasps. Spiders in this genus are 18-24mm in
length and are creamy yellow in colour. Carparachnes' burrow consists
of a long narrow tube bound together with silk. |
|
Eusparassus (Rock huntsman
spider)
Eusparassus
is probably the correct generic name for our rock living Olios
species. Presently the only species in the genus is
Eusparassus palystiformis,
known from southern Africa. |
|
Leucorchestris (white lady spiders)
Leucorchestris is a psammophilous genus occurring on sand dunes in arid
areas. It is reported to be the largest sparassid in southern Africa but it
does not appear to be larger than Palystes
martinfilmeri.
Originally
thought to be a Namibian genus it has since been collected or photographed
from Port Nolloth to Witsand Nature Reserve in the Northern Cape. Known
commonly as white lady spiders one species is known to do a dance and is
known as the Dancing white lady. The purpose of this dance is to communicate
to other males or females by drumming the tarsae against the sand. The
common name is referable to the colour of this genus. Wit dame and Dansende
wit dame are the respective Afrikaans names. The retreat consists of a short
wide silk bound burrow. |
|
Microrchestris
Microrchestris is a small 10-12mm Namibian endemic with two known
species. |
|
Olios Olios is a group of smaller spiders are
rupicolus living under rock on rock while others are green and are arboreal.
The rupicolus species are light brown in colour and may in time be removed
from Olios and placed in the genus Eusparassus. Olios
it appears will be retained for the green arboreal species. 10-14mm.
Olios retreats under rock and produces a flattish sac retreat and egg
sac attached to the underside of a rock or stone. These spiders share a
similar habitat to the flatties
(Selenopidae). |
|
Orchestrella
Orchestrella
an endemic Namibian genus with two species. 10-18mm. |
|
|
Palystella
Palystella is a Namibia endemic with four species contained in the genus.
Size11-18mm
|
|
Palystes (rain spiders, lizard-eating spiders)
These spiders occur mainly on plants where they hunt predominantly insects
but they also eat geckos. They are large spiders, often mistaken for
baboon spiders, and frequently come
indoors where they frighten people. They can bite but it is no more serious
than a bee sting. Females of the two common species, Palystes castaneus
and Palystes superciliosus, construct an egg case in a bush that
is made of dead leaves and twigs drawn together with silk and with a white
silk covering (see image to the right). |
 |
Panaretella (forest huntsman spiders)
Panaretella
Is a genus of small spiders endemic to the forests from Grahamstown to
northern Kwazulu-Natal. There are five species of forest huntsman spiders.
The retreat is two leaves spun together with silk. 12-18mm |
|
Parapalystes
Parapalystes is
derived from the Greek para meaning near or close to
the Latin palaestes or
Greek palaistes, meaning wrestler.
It is a near endemic Cape genus as it occurs in the Eastern, Northern
and Western Cape and also occurring at Oranjemund (Namibia).
To the lay person Parapalystes can be separated
from Palystes on colour and markings. It tends towards grey, has a
yellowish clypeal moustache and dark folium marking on dorsal abdomen.
Spiders reported by Croeser in Namaqualand and Larsen at
Oranjemund and on the Cape Peninsula retreat into an inverted cup shaped
nest. This retreat is produced by pulling desert plants or restios together.
Where they meet the silken retreat is constructed. It was noted that a
species photographed at St Helena (Western Cape), made a simple nest in a
hole in a brick wall. |
|
Pseudomicrommata
Pseudomicrommata is a monotypic genus with
only
one species. The spiders are found in areas with Eragrotis where it
constructs its nest. Pseudomicrommata longipes is easily recognised
by the medial dorsal band running the length of its body. |
|
Rhitymna
Rhitymna
is known from east Africa, Madagascar and Asia. One species has been
collected in southern Africa. |
|
Genera naturalised in southern Africa
Heteropoda
Heteropoda
venatoria a species with a pantropical distribution has been introduced
to Mozambique and south Africa where it is sometime reported to take refuse
in houses. |
