, figs 13–16 (from ‘
Alor Island
, near the airport’,
8° 15' 0" S
,

;
holotype
RMNH 113381
).
Material examined.
AM
C.471156 (
Indonesia
, Alor Island, 3 dry).
Diagnosis.
Shell comparatively large (D =
16–19 mm
), with usually well-developed axial ribs, umbilicus closed. Penis with long epiphallus, short flagellum, inner penial anatomy unknown (based on
Maassen, 2009
).
Comparative remarks.
Comparatively large shell with well-developed axial sculpture and closed umbilicus is most characteristic. Well-differentiated from
R. solorensis
and
R. abbasi
n. sp.
in a molecular phylogeny based on mitochondrial COI and 16S sequences (
Fig. 3
). Specimens from Atauro Island differ by consistently smaller shell, weaker sculpture, narrowly open umbilicus but are differentiated by comparatively low genetic distances (
Table 2
); therefore being recognised as distinct subspecies.
