Type species. Thelepus cincinnataus (Fabricius, 1780) Remarks. Forty-six species are currently included in the genus, including forty-three species listed in Read (2016b) and three new combination species, Thelepus abranchiatus (Hartman & Fauchald, 1971), Thelepus malayensis (Caullery, 1944), and Thelepus verrilli (Treadwell, 1911), as suggested by Hutchings & Glasby (1987) and Londoño-Mesa (2009). Of those forty-six species, only Thelepus plagiostoma (Schmarda, 1861), Thelepus opimus Hutchings, 1990, and Thelepus pulvinus Hutchings, 1990 have been reported from the East China Sea and Hong Kong (Yang & Sun 1988; Hutchings 1990), and none have been reported from Taiwanese waters. The present study adds two more species to the genus.
