Remarks. Poppius (1915) described Allodapus (= Hallodapus) persimilis from Taiwan, and mentioned that it was separable from H. ravenar by the somewhat different coloration, larger eyes and longer antennae. However, both species are very similar to each other in external appearance and hallodapines often have great intraspecific variations in coloration and wing forms. This taxon had not been reported for a long time until Miyamoto (1966) illustrated detailed structure of the endosoma as H. persimilis based on a male from Taiwan. His illustration unequivocally fits what we conceive of as H. ravenar, which is widespread in the Oriental Region and southwestern Japan (strangely, no record of H. ravenar from Taiwan is present; see Schuh, 1984, Yasunaga & Duwal, 2015, Yasunaga et al., 2013b). Images for the lectotype of H. persimilis are now available on a website http://twinsecttype.nmns.edu.tw/specimen/?id=NMNS-HNHM-00043) maintained by National Museum of Natural Science, Taiwan (2017). We also cannot find any significant difference between our H. ravenar specimens and the holotype of H. persimilis. Therefore, we conclude both taxa are doubtlessly conspecific.
