Description
Laccobius (Microlaccobius) fragilis Nakane, 1966 Ḏ弱flǿ牙ḃ
(Fig. 18)
Laccobius (Microlaccobius) fragilis Nakane, 1966: 57.
Laccobius (Microlaccobius) fragilis: Gentili (2003: 422) (records from Taiwan).
Material examined. No specimens were examined.
Published record: Taitung (Gentili 2003).
Distribution. China (Gansu, Liaoning, Shaanxi), Japan (Honshu, Shikoku, Kyushu), Korea, Russia,? Taiwan (Gentili 2003; Nakajima et al. 2020; Przewoźny 2020).
Comments. The first and so far the only record of this species from Taiwan is a male from Taitung (southern Taiwan) mentioned by Gentili (2003). This species is very similar to L. formosus, and can be differentiated by the narrower median lobe of the aedeagus (Fig. 18). We did not find any specimens of L. fragilis in this study, although we also examined specimens from Taitung. The occurrence of L. fragilis in Taiwan hence needs to be reconfirmed. However, more species usually co-occur at localities sampled by us in Taiwan and we hence cannot exclude that L. fragilis may be rare and hence unrecorded by us. Therefore, we still maintain L. fragilis as a member of Taiwanese fauna.
