Genitalia of S. abantensis and S. agnatus are very similar, with only small differences in radix and embolus of the male palpus; differences between the vulvae of the females are more pronounced. Dorsal spination of the femora is given as a good character by Tanasevitch (1990, see above), but material from Georgia exhibits one as well as two spines in one specimen (Otto, pers. comm.).
