Etymology. Named for Atauro Island.
Description. Shell moderate in size (D = 13–19 mm; Table 1 View Table 1 ), with faint to well-developed axial ribs, umbilicus forming a chink or narrowly open. Penial verge with circular folds, penial wall with weakly developed longitudinal pilasters, epiphallus with short flagellum ( Fig. 2C View Fig ).
Comparative remarks. Differs from the nominate form by smaller shell, weaker ribs, more vivid colouration, not completely closed umbilicus. Both island forms are separated by comparatively low genetic distances of about 4% in COI and 2% in 16S ( Table 2 View Table 2 ). Because low genetic differentiation might indicate incomplete reproductive isolation, the Atauro Island populations are described as a subspecies of R. setzeri rather than being recognised as a full species. Rhagada setzeri is well-differentiated from R. solorensis and R. abbasi n. sp. by means of genetic distances of 12–16% in COI and 8–9% in 16S.
