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
).

Distribution.
Known only from

.
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)
