Thysanina Simon 1910

Thysanina Simon, 1910 Thysanina Simon, 1910: 201; Lyle & Haddad 2006: 97. Remarks. Thysanina can be easily distinguished from Trachelas sensu stricto by the smooth rather than tuberculate carapace texture, the presence of ventral cusps and dense scopulae on the anterior tibiae, metatarsi and tarsi of males and females, respectively, and the consistent presence of chevron markings on the abdomen of both sexes (rare in Trachelas sensu stricto). However, Thysanina is itself probably polyphyletic, and may represent three different genera based on morphological and molecular data (Haddad et al. 2021; Haddad 2025). Despite a revision (Lyle & Haddad 2006), wherein a range of genitalic morphology between the six known species was presented, the composition of the genus needs to be revised in future, taking into consideration that more than 15 new species have been subsequently discovered and are awaiting description (C.H., unpublished data).
