Type material. Holotype: Female from Pico da Neblina (2,000 m), São Gabriel da Cachoeira, (00°46'N 66º00'W), Amazonas, Brazil, X.2007, A. A. Nogueira et al. coll. (INPA-AR 6158).

Etymology. The species epithet is a patronym in honor of Adalberto J. Santos, for his contributions to arachnology and to the academic development of the first two authors.

Diagnosis. Females of Chrysometa santosi differ from other species of the genus by the depression of the copulatory opening longer than wide, on ventral view ( Fig. 6G View FIGURES 6 A – I ). Lateral plates covering half of the basal region of the median plate, on posterior view ( Fig. 6H View FIGURES 6 A – I ); median plate racket-shaped in posterior view ( Fig. 6H View FIGURES 6 A – I ), and copulatory ducts opening on the top of the genitalia, while the fertilization ducts opens on the basal region ( Fig. 6I View FIGURES 6 A – I ). Females of C. santosi are similar to C. banos Levi, 1986 , figs.: 170–174.

Description. Male. Unknown.
