Fauna Portal Image No. 2341Diagnosis
(after Framenau & Castanheira, 2022) Male and female L. sexta key out to L. phthisica (L. Koch, 1871) in Framenau & Scharff (2008); however, L. sexta males differ from those of that species in a number of characters, particularly the relatively shorter abdomen which is more than three times longer than wide in L. phthisica, but not so in L. sexta. Males also vastly differ in their pedipalpal morphology. Most evident are the lack of a tegular extension in L. sexta (present in L. phthisica). In addition, the distance between the median apophysis prongs is smaller in L. phthisica and the prongs are of different size, whereas they are much more separated in L. sexta and of similar size. The epigynum has a much broader posterior rim in L. sexta than in L. phthisica.

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.
