Aranea fornicata |
Gasteracantha fornicata is a type of Spiny orb-weaver spider found in Queensland Australia. It is similar in shape to the Austracantha minax which was originally described as Gasteracantha minax. [1]
[edit] Note on taxonomy
This species is sometimes identified as Gasteracantha vittata (L. Koch, 1871). However, it was later discovered that Johan Christian Fabricius had described the species earlier, and according to taxonomic rules, the earlier name has precedence and is the only one that should be used. Also, there are other species that were identified G. vittata at times, namely G. irradiata (by Thorell, 1859), G. sanguinolenta (by Keyserling, 1877) and G. transversa (as subspecies G. v. longicornis by Strand, 1907), further complicating the issue. Furthermore, there is a taxonomic rule that precedence can be circumvented when the original name has never really been used. So today it is even sometimes called Astracantha vittata.
