Diagnosis

Males are distinguished by the rounded, clavate posterior part of the retrolateral tibial apophysis (Fig. 29); excavated and rugose in S. moscai gen. et sp. nov. (Fig. 34); from S. achachay gen. et sp. nov. by their large and rounded ventral tibial apopysis (Fig. 29), absent in the latter (Fig. 39). Females are distinguished by their slit-like copulatory openings (Fig. 30).

Etymology

The speciFc name is a noun in apposition taken from the Kichwa language meaning ‘arrow’, for the arrow-shape marks found on the abdomen.
