). Dorsal disc dark grayish to brown, with white to yellow ocelli, with a darker contour; ocelli small, up to 2/3 eye length and surrounded by smaller, irregular light colored spots. Spots more numerous on disc margins. Ventral disc white to beige, with lateroposterior margins covered by dark blotches; dark color pattern not reaching anterior disc margin. Intensity of pigmentation age and size dependent; older specimens more pigmented. The only male observed (MZUSP 104654) presents larger ocellated spots compared to females of equivalent size. This variation may be due to sexual dimorphism, however since only a single adult male specimen was examined, further investigation is necessary to verify this.
