Opisthoncus species are generally quite easy to recognize to genus because of a small 'lump' between the last pair of eyes. However, several of the more common species are so similar in appearance and surface markings that they are best distinguished from each other by a careful examination of their genitalia. The most recent and comprehensive review of the Australian Opisthoncus species can be found in the following paper: Gardzinska J and Zabka M (2013) "Redescription of the genus Opisthoncus L. Koch, 1880 (Araneae: Salticidae)" Zootaxa 3717, 401-447. This paper contains many images of Opisthoncus species but unfortunately these are all of preserved specimens which therefore have changed colour patterns.

The spider shown on this page is very common in South-east Queensland and is accepted as Opisthoncus parcedentatus by the Atlas of Living Australia and many other matching images in books and on the internet also have been given this name.
