Treatment

Titanattus Peckham & Peckham, 1885: 62 (type species by original designation: Titanattus saevus Peckham & Peckham, 1885 ); Pickard-Cambridge 1900; Simon 1901a; Ruiz & Maddison 2015; Maddison 2015; World Spider Catalog 2017. Agelista Simon, 1900: 383 (type species by original designation: Agelista andina Simon, 1900 ); Galiano 1963a; Ruiz & Maddison 2015; Maddison 2015; World Spider Catalog 2017. NEW SYNONYMY.

Diagnosis. Among all already-described genera considered as thiodinines by Ruiz & Maddison (2015) and here, Titanattus can be distinguished by a high carapace and clypeus (e.g. Peckham & Peckham 1885: fig. 1A), and typical salticid number of spines on their legs (e.g. patellae p1, r0 or p1, r1; many leg spines are absent in other thiodinines; see discussion below) and a heart-shaped sternum, with no keel ( Fig. 9 View FIGURE 9 ; Peckham & Peckham 1885: fig. 1C).

List of species (chronological order):

1. Titanattus saevus Peckham & Peckham, 1885 (type species). 2. Titanattus pegaseus Simon, 1900 .

3. Titanattus andinus (Simon, 1901) comb. nov. 4. Titanattus notabilis ( Mello-Leitão, 1943) . 5. Titanattus pallidus Mello-Leitão, 1943 . 6. Titanattus cretatus Chickering, 1946 . 7. Titanattus paganus Chickering, 1946 . 8. Titanattus novarai Caporiacco, 1955 . 9. Titanattus acanjuba sp. nov.

10. Titanattus euryphaessa sp. nov.
