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 View FIGURES 56–59 with Figs 68 and 70 View FIGURES 68–71 , 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 View FIGURES 60–63 with Figs 74–75 View FIGURES 72–75 , Galiano (1977b: fig. 17) and Bustamante & Ruiz (2017 fig. 26F)].
