Comment(s) on data
Chaenostoma sinuspersici (Naderloo & Türkay, 2010) replaces C. boscii in most places of the IWP. See also Rahayu & Nugroho (2011), Zootaxa. M. boscii is known with certainty only from Red Sea. According to Davie (2012: 151, Memoirs QM, note in PDF) the correct name requires futher study: 'C. boscii was recently restricted to the Red Sea, and the Australian representatives of this species were referred to a widely distributed new species Chaenostoma sinuspersici (Naderloo & Türkay, 2011). Unfortunately, this new species seems very likely to prove to be the same as Chaenostoma orientale Stimpson, 1858, which has been long synonymiised under C. boscii. Thus, the eventual valid name for this species in Australia will require further study.
According to Shih et al. (2015; Ocypodidae Taiwan) and Teng et al. (2016), the geographic distribution of C. sinuspersici is restricted to WIO, specimens from others places (Australia, New Caledonia) being of C. orientale.
