Prosoma: carapace pyriform, narrowing gradually anteriorly; light yellow, suffused with purplish pattern (Fig. 44C); pars cephalica flat; fovea not visible. Sternum light yellow, suffused with purplish color, as long as wide. Endites light yellow suffused with purplish tinge; with serrula; labium light yellow suffused with purplish tinge. Clypeus nearly vertical; short. Chelicerae light yellow, laterally slightly curved; promargin with a series of six teeth reaching the lamina; retromargin with two very small denticles (Fig. 56I). Eyes: six contiguous eyes surrounded by black pigmentation; PME and ALE nearly subequal, PLE largest (Fig. 44C). Opisthosoma oval; purplish. Legs light yellow; leg formula 4123; leg lengths I 2.04 (0.59, 0.14, 0.61, 0.41, 0.28); II 1.88 (0.55, 0.16, 0.54, 0.37, 0.26); III 1.63 (0.48. 0.13, 0.43, 0.34, 0.25); IV 2.15 (0.63, 0.14, 0.59, 0.47, 0.32). Genitalia (Fig. 43). Palpal femur long; palpal tibia as long as cymbium (Figs 43A–B). Cymbium conical, without prolateral extension. Bulb nearly trapezoidal. Embolus short, dark and basally without distinct associated sclerites; sperm duct initially wide, narrowing distally (Fig. 43D). Female. Total length 1.19; carapace length 0.51; carapace width 0.42; abdomen length 0.50; abdomen width 0.37. Similar to male in color and general features (Figs 44D–E) but larger. Chelicerae unmodified.
