Remarks. It can be identified with the key to Palaearctic Lispe by Hennig (1960), who also illustrated the male and female terminalia (Hennig 1960, text-figs 111, 131, 160, plate 18 fig. 369, plate 19 fig. 370, plate 20 fig. 407). It belongs to the tentaculata -group of Lispe (Hennig 1960) (see comments on the group under L. consanguinea ). It can also be identified with the key by Vikhrev (2011a) to the Palaearctic species of the tentaculata -group, with an illustration of the cercal plate ( Vikhrev 2011a, fig. 2.1). Vikhrev (2014) also keyed and illustrated the species, and more recently Fogaça and Carvalho (2018, figs 1e, 3f, 5j, 6f, 7f, 8f) have keyed, redescribed and illustrated the species. In a more recent revision of the Australian species of Lispe by Pont (2019, figs 9–15), notes and illustrations of male and female terminalia were provided.
