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.
