Etymology. The specific name is after Tyrion Lannister, fictional character from the TV series “Game of Thrones”, because of his short stature, sharing this characteristic with the representatives of this species.

Diagnosis. Males and females of T. tyrioni   sp. nov. resemble those of T. minuta   , T. perian   and T. camilae   sp. nov. by the general appearance (carapace yellow with black borders, a pair of brown stripes on the thoracic region, abdomen dorsally as in genus), but with larger body, almost like that of T. nicoleti   (see Bustamante et al. 2015). Males of T. tyrioni   sp. nov. differ from the remaining species of the genus by having a longer embolus (480°, 1T+120°) (compare Figs 68 and 70 View FIGURES 68–71 with Figs 56 and 58 View FIGURES 56–59 ; Galiano 1977b: fig. 17 and Bustamante & Ruiz 2017: fig. 26A). The females resemble those of T. minuta   , T. perian   and T. camilae   sp. nov. by the shape of the rounded spermathecae, but differ by the longer copulatory ducts (compare Figs 74–75 View FIGURES 72–75 with Figs 62–63 View FIGURES 60–63 ; Galiano 1977b: fig. 17 and Bustamante & Ruiz 2017: fig. 26F).

Color in alcohol: carapace yellow with black borders, two brown stripes in thoracic region, abdomen dorsally yellow, with three longitudinal dark stripes, middle one continuous, others discontinuous, sides with one longitudinal dark stripe (five in total), venter white with dark areas, spinnerets yellow. Femur I yellow, patella, tibia and metatarsus darker, tarsus yellow, II yellow, with brown metatarsus, III and IV yellow ( Figs 64–65 View FIGURES 64–67 ).

Female (Paratype, UBC-SEM). Total length 2.69. Carapace length 1.15, width 0.77, height 0.48. AME diameter 0.23. Ocular quadrangle length 0.65. Anterior eye row width 0.72. Posterior eye row width 0.78. Abdomen length 1.53.

Distribution. Known only from Arizona, USA.

Notes. This species was mentioned as “cf. Cyllodania   sp. [d286]” in Ruiz & Maddison (2015) and “ Thiodina aff. minuta   ” in Bustamante & Ruiz (2017: 345).

Due the general appearance and the reduced body size, T. minuta   , T. perian   , T. camilae   sp. nov. and T. tyrioni   sp. nov. could form a monophyletic group: the T. minuta   species group (here proposed). A molecular phylogenetic study ( Ruiz & Maddison 2015) suggested a close relationship between T. tyrioni   sp. nov. (“cf. Cyllodania   sp. [d286]” in that paper) and Arachnomura querandi Bustamante & Ruiz, 2017   (see discussion in Bustamante & Ruiz 2017: 345).
