Takahiro Yoshida, Michael Karner, and Toshiya Hirowatari (2018) This study revises the taxonomy of Taiwanese species in the genus Psammoecus Latreille, 1829. A new species, P. taiwanensis sp. nov., is described, and six species from Taiwan are recoded for the first time: P. harmandi, Grouvelle, 1912, P. dentatus Grouvelle, 1883, P. trimaculatus Motschulsky, 1858, P. triguttatus Reitter, 1874, P. labyrinthicus Yoshida and Hirowatari, 2014 and P. hiranoi Yoshida and Hirowatari, 2013. The following taxonomic synonyms are proposed: P. delicatus Grouvelle, 1908 = P. x-notatus Grouvelle, 1912 syn. nov. = P. nitidior Grouvelle, 1919 syn. nov. = P. raffrayi Grouvelle, 1919 syn. nov.; P. harmandi, Grouvelle, 1912 = P. boreas Yoshida and Hirowatari, 2014 syn. nov.; P. dentatus Grouvelle, 1883 = P. scitus Yoshida and Hirowatari, 2014 syn. nov.; P. simonis Grouvelle, 1892 = P. stultus Grouvelle, 1912 syn. nov. A key to Taiwanese Psammoecus species, a redescription of P. delicatus, and notes on the variability of P. harmandi are provided.

Key words: Taxonomy, Cucujoidea, New species, Synonymy, Taxonomic key.
