Remarks.

This genus was described by Wollaston based on material from the island of St. Helena. Additional species were described later, and the present number of valid species is five. The genus was redescribed and compared to all other Palaearctic Trachyphloeini by Borovec (2009), then subsequently revised by Borovec (2014), based on material from China, Vietnam, Japan, Korea, and the Moluccas. Morimoto (2015), in his monography of Japanese Entiminae , surveyed the Japanese species of the genus. China is the most northwestern part of the range of the genus, and Trachyphloeosoma was first recorded from this country only in 2009 by Borovec, based on one male from Yunnan, and subsequently by Borovec (2014) based on several additional specimens of the same species. Following examination of some newly sifted material from China, and comparing this with Morimoto’s (2015) review of the genus from the Japanese islands, we can state that the species collected in China are new to science. We can thus correct the name of the species so far recorded from China. This newly collected material from China was erroneously identified as T. advena Zimmerman, 1956 and was listed under this name in the Palaearctic catalogue ( Alonso-Zarazaga et al. 2017). After dissection and thorough examination, we are able to recognise the specimens as distinct from T. advena and belonging to three different species, which are described below.
