During long time, Teredorus Hancock, 1907 and Systolederus Bolívar, 1887 were considered as separate genera (Otte, 1997). Recently, almost all species of the genus Teredorus from the Old World were transferred to the genus Systolederus (Devriese &amp; Husemann, 2023) . Undoubtedly, three species of Teredorus described from China and Cambodia (Zheng, 2015; Zha &amp; Ding, 2017; Storozhenko, 2019) must be also placed in Systolederus and new combinations are proposed here: Systolederus longidorsalis (Zheng, 2015), comb. nov., Systolederus jinshaensis (Zha et Ding, 2017), comb. nov., and Systolederus vicinus (Storozhenko, 2019), comb. nov. Nowadays four species are known from the Philippines: S. femoralis (Walker, 1871), S. angusticeps (Stål, 1877), S. haani Bolívar, 1887, and S. boettcheri Günther, 1939 (Walker, 1871; Stål, 1877; Bolívar, 1887; Günther, 1939; Kevan, 1966; Cigliano et al., 2025).</p></div>	https://treatment.plazi.org/id/03B187E6FFE91B58FF380C7CFED2563B	Public Domain	No known copyright restrictions apply.
