Etymology. The specific epithet is in honor of the indigenous ethnic Suyá tribe that live in the Xingu Indigenous Park, which borders Fazenda Tanguro in the northeastern part of the state of Mato Grosso.

Diagnosis. Males of Camillina suya are similar to those of C. gaira Platnick & Shadab, 1982 , by the shape of the embolus, but differs by having a distally wider and more robust embolus and a narrower terminal apophysis (Figs 3–5, 30–33) while in C. gaira the embolus is longer and distally pointed and the terminal apophysis is longer (see Platnick & Shadab, 1982: figs 49, 50). Females resemble those of C. gaira , with a large and oval median field of epigynum, and a wider than long, rounded and robust primary spermathecae, but the distance from the posterior border of the median field to the primary spermathecae is twice the diameter of the spermathecae in C. suya (Figs 6–7, 35), while it is just once its diameter in C. gaira (see Platnick & Shadab, 1982: figs 51, 52).

Variation. Length (10♂) total 3.52–4.38, carapace 1.61–1.87, femur I 0.86–1.24; (6♀) total 3.82–4.73, cara- pace 1.53–1.73, femur I 1.16–1.54.

Distribution. Northeastern part of the State of Mato Grosso, Brazil.

Life history and habitat preferences. This species was collected in a transitional area between the biomes of the Amazon Forest and Brazilian Cerrado (savanna), located in a region known as “Arc of Deforestation”. This region is subject to one of the highest pressures of deforestation in the Brazilian Amazon ( Oliveira et al., 2010).
