Male terminalia. Tergite VIII (Figs 26 & 27) sparsely covered with thick setae apically, nearly as long as broad, with a deep notch apically. Sternite VIII (Figs 26 & 27) sparsely covered with setae at sides of apex, broader than long, expanded in middle, and truncated apically; spiculum relictum nearly as long as sternite VIII. Spiculum gastrale (Fig. 28) Y-shaped, slender, distinctly longer than sternite VIII.
Aedeagus. Tegmen (Figs 29–31) curved, shorter than penis; parameres sparsely covered with thick setae apically; phallobase nearly 3.0 times as long as parameres, abruptly expanded near apical 1/3 and gradually constricted towards base. Penis (Figs 32–34) curved and thick in profile, gradually constricted towards apex; dorsal struts elongate, nearly 1/2 as long as penis, slightly curved in profile; dorsal plate rounded apically; ventral plate distinctly longer than dorsal plate, rounded apically.

Host plant. Zanthoxylum ailanthoides (Rutaceae), Trachelospermum gracilipes var. liukiuense (Apocynaceae) are recorded as hosts (Ohbayashi & Niisato, 2007).
Adult occurrence: Kusama et al. (1984), Ohbayashi et al. (1992), Ohbayashi & Niisato (2007) reported the adult occurrence was from March to July, Chou (2008) reported the adult occurrence was all year round.
Distribution. China: Taiwan (Kaohsiung, Nantou, Pingtung); Japan: Amami islands (Amami-Oshima, Kikaijima, Okinoerabujima, Tokunoshima), Koshikijima Islands (Shimo-Koshiki-jima), Kuchinoerabu-jima, Kyushu (Kagoshima, Meshima), Okinawa Island, Sakishima Islands (Iriomote-jima, Ishigaki Island), Tanegashima, Tokara Islands (Akusekijima, Nakano-shima, Suwanosejima, Takara-jima), Yakushima.
Comments. Gressitt (1938) received male specimens (holotype and paratopotype) from Mr. Y. Matsuda (Kyoto), and there were additional specimens in the collection of Mr. Y. Matsuda, but Gressitt described this species only based on male specimens. Kusama & Takakuwa (1984) described the differences between males and females, the apex of ventrite V with a narrow notch in males, the apex of ventrite V widely truncate in females. After comparing 3 specimens (1 male and 2 females), the senior author found the shape of the apex of ventrite V is indistinctly different between males and females. More specimens are needed to adequately determine the differences between males and females. There is a holotype photo of E. matsudai in the database “A Photographic Catalog of the Cerambycidae of the World” (Bezark, 2013).
