The spider in the above photos looks very similar to one identified by Dr. Robert Raven (Queensland Museum) as Desognaphosa yabbra. Almost all of the described Desognaphosa species were found in North Queensland, the notable exception being D. yabbra, the range of which is known to extend into Northern NSW. However, the specimen in the photos above differs from D. yabbra in several respects: it was found inland from Sydney, it has a pattern of pale marks on its dorsal abdomen which does not match those in the photo examined by Dr. Raven, and (most importantly) it does not appear to have porrect (forward-pointing) chelicerae which Norman Platnick says is a characteristic of Desognaphosa species. However, it does not seem to belong in any other Australian spider family and it is possible that it is actually an undescribed Desognaphosa species and that its chelicerae are simply bent downwards for some unknown reason, perhaps including immaturity.
