The genus was recently redefined and enlarged , because of the additions and redescriptions of several species, and now comprises 71 recognized species (Rahayu & Ng, 2010;Ng et al, 2016;Cannicci et al, 2017;Li et al, 2018Li et al, , 2019Shahdadi et al, 2018aShahdadi et al, , b, 2019aFratini et al, 2019;. This makes it the most species-rich genus of the family Sesarmidae.…”
