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 58View FIGURES 56–59 with Figs 68 and 70View 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 62–63View FIGURES 60–63 with Figs 74–75View FIGURES 72–75, Galiano (1977b: fig. 17) and Bustamante & Ruiz (2017 fig. 26F)].
