Diagnosis.
This species resembles S. suea sp. nov. but can be distinguished by the following: the absence of eyes (Figs 20A View Figure 20 , 21B View Figure 21 ) (vs. presence), the presence of a bulbal apophysis (Fig. 20B-D View Figure 20 ) (vs. absence), the presence of a dorsal spine on the palpal femur distally (arrows on Fig. 20C, D View Figure 20 ) (vs. spine absent), and the absence of a spine on the palpal tibia retrolaterally (Fig. 20D View Figure 20 ) (vs. spine present). Receptacle is tube-shaped (Fig. 21A View Figure 21 ) (vs. globular).
