Diagnosis.
This species resembles S. acicularis comb. nov. but can be distinguished by the following characters: the eyes are vestigial (Figs 26B View Figure 26 , 27A View Figure 27 ) (vs. ringed with black); the receptacle is coiled into 1.25 loops (Fig. 26A View Figure 26 ) (vs. 2.5 loops); the embolus is longer than the cymbium (Fig. 27C, D View Figure 27 ) (vs. shorter), and the palpal tibia/cymbium ratio is 0.4 (Fig. 27C, D View Figure 27 ) (vs. 0.45).
