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.
