the valva is stronger, longer, apically less tapering; the cucullus is larger, more quadrangular, the additional process of the outer margin is present, the pollex-like extension is considerably larger, stronger. The fultura inferior of S. t. semialba is narrower, more elongate, its lateral margins almost straight, the apical incision is small, narrow; the valva is narrower, apically more tapering; the cucullus is smaller, triangular, the additional process of the outer margin is missing, the pollex-like extension is much shorter, weaker. The aedeagus of S. t. taiwana is somewhat longer and stronger than that of S. t. semialba, the basal curve of the vesica has no cornuti or only a few, sparse, short spines, the basal plate of the terminal cornutus is larger, its apical process stronger, longer. These strongly isolated taxa represent most probably two distinct species, the differences in the external appearance are rather conspicuous and those of the male genitalia are also well-discernible. These two taxa are considered here as two races of the same species because of the absence of the female sex of semialba, the discovery of the other sex of the latter taxon and the study of its genitalia can clarify the status of S. t. semialba. The comparison of the external and gen italic features of S. taiwana and the S. apocrypha—S. farmosa species-pair is given in the diagnoses of the two newly described species. Fig. 17.
