Megaphyllum silvaticum (Verhoeff, 1898) syn. nov., nomen protectum: Investigation of Julus austriacus var. nigrescens Latzel, 1884 syntypes showed that it is a subjective senior synonym of the later described M. silvaticum. However, here we propose reversal of precedence under Article 23.9. (ICZN 2000). The younger name is valid because the senior name has not been used after 1899 (meeting condition 220.127.116.11), while the junior synonym was used as its presumed valid name in the last 50 years by at least 10 different authors in at least 25 publications encompassing a span of not less than 10 years (e.g. Čaputa 1988; Ceuca 1992; Chornyi & Golovatch 1993; Enghoff & Kime 2009; Foddai et al. 1995; Golovatch 1992; Gulička 1985b; Jedryczkowski 1979; Lác 1991; Lazányi & Korsós 2008; Lazányi & Korsós 2010; Lazányi et al. 2012; Lokšina & Golovatch 1979; Mock 2001; Mock 2002; Piróg et al. 1990; Schmölzer–Falkenberg 1975; Stojałowska & Bielak–Oleksy 1970; Stojałowska & Starega 1974; Strasser 1965; Strasser 1966a; Strasser 1971a; Strasser 1971b; Strasser & Minelli 1984; Tăbăcaru 1976; Voigtländer et al. 1997; Wytwer 2000) meeting condition 18.104.22.168.
