Opisthoncus tenuipes

Fact Box
Opisthoncus tenuipes
(ID derived from a paper by Gardzinska and Zabka but this spider may actually be the same as O. abnormis: see below. It has also been suggested this species should not be an Opisthoncus species but it clearly does have the 'Opisthoncus bump' between the lateral eyes)
Body length:
female: 5 mm
male: about 4.5 mm
May be found wandering on green leaves or in its retreat
This spider is probably too small to be dangerous to humans

The most recent revision of the genus Opisthoncus appears to be the 2013 paper by Gardzinska and Zabka in which there are many colour photos of Australian Opisthoncus species. Unfortunately, they are all of preserved museum specimens which lack the normal colour patterns and surface markings of living specimens. They have also suffered significant damage during storage. In this paper the authors say that "it is likely that Opisthoncus tenuipes and Opisthoncus abnormis represent a single species. However, because of lacking the male type of O. abnormis, this has to be verified on new material." More recent publications seem to be stating that O. tenuipes and O. abnormis are indeed the same species but the World Spider Catalog in July 2017 still lists them as separate species.

Spider(s) with a very similar appearance: None.
