Remarks. Webb & Vilbaste (1994) previously recognized the B. punctata species complex to comprise five valid species from the Oriental fauna: B. punctata Blocker, B. lineolata (Horvath), B. arhenana Dlabola, B. tiaowena Kuoh, B. uncinata Kuoh. We could find only slight differences in Chinese specimens examined and identified as B. punctata, B. tiaowena and B. uncinata based on external morphological characters (coloration, shape of aedeagal base, the radian of bending of aedeagal shaft of male genitalia), but whether these slight differences represent interspecific variation remains unknown. We retain them as separate species following Webb & Vilbaste (1994), but additional data, including molecular data and morphological characters will be needed to confirm their status.
