Figs 1–2 , 24–38 Etymology. The specific name honours the Ecuadorian writer and politician Marieta de Veintimilla, 1855–1907, who served as the 11 th first lady of Ecuador and became a feminist icon of the early 20 th century. Diagnosis. The males of Cyllodania marietae sp. nov. resemble those of Atomosphyrus tristiculus Simon, 1902 by having a mastidion on the male paturon ( Fig. 25 ), but differ by the shorter embolus (840º, 2T+120º, in A. tristiculus ; 360º in C. marietae sp. nov. ), and longer RTA and RvTA ( Figs 31, 33–34 ) (shorter in A. tristiculus ). Additionally, males of C. marietae sp. nov. differ from all other species of the genus by the poorly developed dpC (distal embolar projection of Cyllodania ), and the presence of mastidion ( Figs 25–26 ) (absent in the other species). Females of C. marietae sp. nov. resemble those of C. bicruciata Simon, 1902 by the poorly differentiated spermathecae, but differ by the shorter copulatory ducts; they also resemble those of Titanattus cordia Edwards & Baert, 2018 by the bilobed posterior margin of the epigyne, but differ by the longer copulatory ducts and also by the general appearance of body (e.g. the carapace is higher in T. cordia ). Females of C. marietae sp. nov. differ from all other species of the genus by having a coupling pocket in the epigyne ( Figs 35–36 ). FIGURES 1–2. Cyllodania marietae sp. nov. live female. © W.P.

Distribution. Known only from Ecuador . Inclusion in Cyllodania . Due to the presence of the amycoid mastidion on the male paturon ( Fig. 25 ), the placement of C. marietae sp. nov. in this genus is not obvious, since the only thiodinine genus known to date with the presence of the amycoid mastidion was Atomosphyrus (compare Galiano 1966 : figs 10–12; Bustamante & Ruiz 2017 : figs 5A–5C and our Fig. 25 ). The species is thought to belong in Cyllodania by the similarities with C. bicruciata ( type species, see Figs 22–23 ), sharing the dorsal longitudinal band of white scales, which is easier to see in females ( Figs 1–2 ). This is a synapomorphy of Cyllodania (see Figs 22–24, 27 ) according to Bustamante & Ruiz (in prep.), who carried out the most recent cladistic analysis including all genera of Thiodinini , Scopocirini and Sarindini (“node 2” in Ruiz & Maddison (2015)) . Also, the male palp is similar to that C. bicruciata and C. zoobotanica Bustamante & Ruiz, 2017 by the presence of an embolar projection ( Figs 30, 32 ). The epigyne is similar to that of C. bicruciata by the shape of spermathecae. Also, it is similar to that of Titanattus cordia (compare our figures with Edwards & Baert 2018 : figs 4C, D and 5C) by the bilobed posterior margin. According to Ruiz & Maddison (2015) and Bustamante & Ruiz (in prep.), C. marietae sp. nov. is not closely related to the Titanattus . Note. This species was mentioned as “cf. Atomosphyrus sp. [S223/S172]” in Ruiz & Maddison (2015: 265) .
