Tamopsis brisbanensis (QM)|
(or a related species: see below)
female: 7 mm|
male: 4 mm
Hersiliids normally live on dry bark that matches their colour well, so they are difficult to see until they move. A good indicator that they are there
is the presence of their egg sacs, which are small round white spheres suspended rigidly on a silken stalk 10-15 mm long
May be too small and timid to cause harm to any human
The identity of the spider presented above is somewhat uncertain because there apparently are at least ten described Tamopsis species in the area of South-east
Queensland where the specimens in the above photos were found and they all have a similar appearance, an examination of their genitalia being necessary if
they are to be identified to species. The name Tamopsis brisbanensis has been used on this page because it is known to be a common Tamopsis species in South
Queensland and Northern NSW.
The most significant physical features of this spider are the very long spinnerets. The slender legs and camouflage colours are also important for identification purposes. Males are often found on the trunks of living trees in Spring. The small round egg sacs are easy to find in Autumn in districts where this species is common.
Spider(s) with a very similar appearance: Tamopsis fickerti.
