Two New Pseudoscorpion Species of the Coastal Genus L. Koch, 1873 (Garypidae) and an Updated Checklist of the Pseudoscorpiones of Taiwan.

Pseudoscorpions are predatory microarthropods that feed on even smaller animals, such as mites and springtails. While these organisms are generally considered terrestrial and live in the leaf litter or under barks or rocks, some pseudoscorpions live in the intertidal area, including species in the genera , , and in the family Garypidae. This study describes two new species of the genus L. Koch from Southern Taiwan, Lin & Chang sp. nov. and Lin, Huang & Chang sp. nov., reviews the pseudoscorpion fauna of Taiwan, and provides an updated checklist of the country. Specimens of the two new species were collected in seashore habitats and their status as new species were supported by both morphology and molecular phylogenetic analysis. Our discovery marks the first new species of pseudoscorpions reported in Taiwan since 1937, as well as the first records of the family Garypidae in Taiwan and of in East Asia. Moreover, the discovery of these two new species in Taiwan fills the regional distribution gap between in Thailand and southward and its closely related genus in South Korea and Japan. The location where Lin, Huang & Chang sp. nov. was found also represents the northernmost distribution of the genus in the West Pacific.
