Since its original description in 1943, Hesperosoma (Hemihesperosoma) miwai (Bernhauer, 1943) has been redescribed by multiple authors (Hayashi, 1993a; Schillhammer, 2015), albeit without having seen the type specimen. In our study, the holotype specimen of Amichrotus miwai Bernhauer, 1943 was examined, and it was concluded that all subsequent redescriptions of this species are in line with its type specimen. We also provide additional distribution data for H. (Hem.) miwai, confirming that this species is endemic and widespread throughout the island of Taiwan. In addition, a possible phytophagous behavior was discovered during field observations. The plant-associated behavior of several Staphylininae species is also discussed within our study.
