(after Framenau et al. 2023): Males of K. obelix can be separated from other Kochosa species by a thorn-like apophysis on the retrolateral side of the embolic division of the bulb, that can clearly be seen without dissecting this section. Kochosa tasmaniensis has a similar thorn, but in that species, the thorn points apically, whereas it points retrolaterally in K. obelix. The epigyne of K. obelix is very similar to that of K. westralia. In addition to the similar median septum, both species also have raised protuberances laterally of the epigyne. However, the profile of the median septum is much flatter, i.e. much less raised in K. obelix than that of K. westralia and the spermathecal heads are comparatively larger, with the spermathecal stalks attaching posteriorly, not dorsally.

Fauna Portal Records
The map shows all records that have been verified as part of the Fauna Portal project and may not represent the true distribution of a species. Specifically, for described species, check the link to the Atlas of Living Australia on this page for potential wider distributions. Fauna Portal Reference specimens and Linnean types are shown in red. If you identified a specimen that exceeds the distribution of an undescribed species as illustrated here, please contact the Fauna Portal team who can assist with the lodgement of the specimen in a public institution and display on the map.
