Fauna Portal Image No. 4433Diagnosis
(after Framenau & Baehr 2016): Care must be taken when identifying Tasmanicos gilberta as these spiders are very similar to T. fulgor and T. leuckartii, in particular if the ventral light patch of the opisthosoma is poorly developed in T. leuckartii. All three species have been found sympatrically and in large pitfall trap series of one species, each of the other one was often represented by single specimens. Males of T. gilberta differ from those of T. fulgor by the straight ventral edge of the tegular apophysis, which is shallow U-shaped in T. fulgor. Males of T. gilberta and T. leuckartii are best distinguished by the shape of the terminal apophysis, which is broad and flat with an apical bent tip in T. gilberta, but apically twisted in T. leuckartii. Females of T. gilberta differ from both T. fulgor and T. leuckartii by the much narrower median septum, which forms a sharp edge in particular anteriorly.

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.
