: The general coloration under alcohol is the same as soil particles encrusted on the body, which is pale brown (Figures 1-4, 6, 8). Chelicerae orange ventrally (Figures 2, 7, 9), becoming brown dorsally (Figures 1, 4), fangs of chelicerae dark reddish brown (Figure 2). The carapace has reddish coloration when the soil particles are cleaned. Sternum pale orange; endites and labium orange (Figure 2). Legs olive color when soil particles are cleaned, becoming paler on tibia, metatarsi, and tarsi. The opisthosoma was difficult to clean, even with longer time in the ultrasonic cleaner, and the coloration could be similar to the carapace. Spinnerets pale yellow.
