Thiodina camilae
sp. nov.
Figs 9–10

Etymology.
The specific name honours Camila Cerón M.D., best female friend of the first author for more than 20 years, in recognition of her friendship, support, encouragement and patience. This also alludes to her short stature, like the representatives of this species.
Diagnosis.
Males and females of
T. camilae
sp. nov.
resemble those of
T. minuta
(Galiano, 1977)
,
T. perian
Bustamante & Ruiz, 2017
and
T. tyrioni
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) and small body. Males of
T. camilae
sp. nov.
differ from those of
T. minuta
and
T. perian
by the length of the embolus of the palp (360°), longer than the embolus of
T. minuta
(270°), but shorter than the embolus of
T. perian
(450°, 1T+90°) and
T. tyrioni
sp. nov.
(480°, 1T+120°) [compare
Figs 56 and 58
with
Figs 68 and 70
,
Galiano (1977b
: fig. 14) and
Bustamante & Ruiz (2017
: fig. 26A)]. The females resemble those of
T. minuta
,
T. perian
and
T. tyrioni
sp. nov.
by the rounded shape of the spermathecae, but differ by the longer sclerotized portion of the copulatory ducts [compare
Figs 62–63
with
Figs 74–75
,
Galiano (1977b
: fig. 17) and
Bustamante & Ruiz (2017
fig. 26F)].
