“…The aphodiine tribe Stereomerini was established by Howden and Storey (1992) based on the genus Stereomera Arrow, 1905, from Singapore. Currently, 9 genera and 22 species from the Oriental and Australian regions are recognized in Stereomerini (Howden and Storey 1992, 2000; Bordat and Howden 1995; Storey and Howden 1996; Maruyama 2009; Vårdal and Forshage 2010; Maruyama and Nomura 2011; Král and Hájek 2015). The Oriental species are known to be extremely rare; all of them are known from single or a few specimens collected so far.…”
