Remarks.

This species is distinguished by the digitate process on the sacculus in the male genitalia bearing either dense tufted bristles or five enlarged, flattened bristles distally.

Discussion.

In the examined specimens, the appearance of the adults and the female geniatlia are identical, but the male genitalia have two types (Figs 15a and 15b): in figure 15a, the relatively elongate uncus looks like a pair of long ears of a rabbit, and the slender digitate process of the sacculus bears five enlarged, flattened bristles distally; in figure 15b, the short uncus is emarginated posteriorly and somewhat heart-shaped, and the digitate process of the sacculus is relatively broad and bears dense tufted bristles distally. The two types of male genitlia might represent two different species, but in this paper we treat these differences as individual variations. We may confirm whether they are two species or just one species after a geographic analysis, which can be done when more specimens are available.
