Rhagada solorensis floresiana
–

,

(partim).
Taxonomic history.
Martens (1891)
recognised
R. solorensis
as distinct by its thinner, more turreted shell, less thickened columellar lip and slightly different colour. This taxon has subsequently been treated as a subspecies of
R. solorensis
by
Rensch (1931)
and
Maassen (2009)
based on shell features. I prefer following the original concept and maintaining
R. floresiana
as a distinct species (see also under
R. solorensis
). Genitalia were figured by
Wiegmann (1893)
, who noted that in this illustration the insertion of the penial retractor was missing.
Diagnosis.
Shell comparatively large (D =
16–19 mm
), smooth or with fine axial ribs only, umbilicus forming a chink or narrowly open, peripheral band particularly welldeveloped (
Martens, 1891
).
Comparative remarks.
Shell similar to
R. solorensis
; species poorly defined by shell characters only; comparative study of anatomical and molecular characters required to confirm status.
