Four new species of theridiid spiders in the genus Phoroncidia Westwood, 1835 are described from Madagascar: Phoroncidia wrightae sp. nov., Phoroncidia vatoharanana sp. nov., Phoroncidia roseleviorum sp. nov., and Phoroncidia ambatolahy sp. nov. Additionally, the male of Phoroncidia aurata O. Pickard-Cambridge, 1877 is described and imaged for the first time. New images are also included for the type species of the genus, Phoroncidia aculeata Westwood, 1835. The present study describes the first new species of Phoroncidia from Madagascar since 1913 and increases the number of described Phoroncidia from Madagascar from three to seven species.
