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)].
