DIAGNOSIS: Males can easily be distinguished from those of the sympatric species
S. pich
(and those of the other Ecuadorean males) by the reduced eyes (fig. 688), the shorter, more distally originating embolus (fig. 695), and the small protrusion situated medially of the embolus on the palpal bulb (fig. 694); females share the eye reduction and have a narrower anterior epigynal sclerite that occupies more than one-third of the width of the epigynal atrium (figs. 702– 704).

MALE (PBI_OON 16244, figs. 688–695). Carapace length 0.62 (abdomen missing). Carapace granulations present only around lateral and posterior margins, heaviest on sides of posterior declivity; eyes reduced, ALE separated by less than their diameter, PME separated by less than their radius. Sternum smooth. Endites unmodified. Abdomen unpatterned, scuta smooth. Palpal femur moderately enlarged; embolus originating at about one-fifth of cymbial length, bulb with knob situated near embolar origin.
