Rhagada floresiana ( Martens, 1891)

Helix (Rhagada) floresiana Martens, 1891: 235–236 , pl. 14, figs 13, 14 (from ‘ Flores, Maumere’ , 8° 37' 12" S, 122° 13' 12" E; 3 syntypes ZMB Moll. 44732, not seen).

Rhagada solorensis floresiana – Rensch, 1931: 95, Maassen, 2009: 66 (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.
