Diagnosis. The new species is similar to S. cuyapo Li & Li sp. nov. but can be distinguished by the very short copulatory duct that connects the spermathecae to the afferent spermathecae and the size of the spermathecae (Fig. 21A). S. cuyapo Li & Li sp. nov. has a long, curved copulatory duct and small spermathecae (Fig. 20A).
