Habitus as in figs 2D, E. Carapace yellow, with large brown marks medially and brown marginal band; ocular area yellowish, with brown band at median and laterally; clypeus brown; sternum yellowish, with brown marks (fig. 2F).

Chelicerae as in figs 9C, D, with pair of black apophyses distally, pair of unsclerotized apophyses proximolaterally, and pair of small prominences frontally.
