Abstract
Two new species of the leucophoropterine plant bug genus Sejanus Distant are described, namely S. epicurus n. sp. (Pingtung, Taiwan) and S. ryujin n. sp. (Nagasaki, Japan). Both species were recently confirmed to be associated cryptically with the bracts and flower buds of Hibiscus spp. (Malvaceae). An updated key is provided to aid in identification of the Japanese and Taiwanese congeners.
