The different sclerites of genitalia or
hypopygium of each species were examined and
illustrated. According to Zumpt (1973), the lateral
sclerite was divided into two parts, pregonite and
postgonite (Figure 8). In this study, the horned
sclerites were clearly distinguished among the
three species. The various sclerotized plates were
also different in shape among S. calcitrans, S.
sitiens and S. indica (Figure 9).
