Diagnosis

Males are easily distinguished from all congeneric species by their large patellar apophysis ( Fig. 34 ), from S. wachi gen. et sp. nov. by the sinuous end of the male embolus ( Fig. 33 ), strongly curved in the latter species. Females are distinguished by their V-shaped epigynal Fap and hook-shaped copulatory openings ( Fig. 35 ).

Etymology

The speciFc name is in honour of Dr. Franco Mosca, scientist and surgeon, for his contribution to Otonga Fundation.
