Rhagada solorensis (partim) – Vermeulen & Whitten, 1998: 127, fi g. 129.

Rhagada solorensis solorensis – Maassen, 2009: 66 (partim).

Material examined. AM C.327851 ( Indonesia, Nusa Penida , Goa Giri Putri, 8° 45' N, 115° 30' E, 5 wet) .

Taxonomic history.Apparently not aware of Falconieri’s description, this species was subsumed under R. solorensis by Vermeulen & Whitten (1998) and Maassen (2009). The original description focuses on characters exhibited by several species but provides little information permitting the recognition of this species.

Diagnosis. Shell moderately large (D = 14–15.5 mm), with fine axial growth lines, umbilicus forming a chink or narrowly open. Penial verge smooth with pointed tip and well-developed sperm groove, inner penial wall smooth, epiphallus with moderately long flagellum ( Fig. 2B ).

Comparative remarks. Confused with R. solorensis by Vermeulen & Whitters (1998) and Maassen (2009), who depicted shells of this species as R. solorensis . Most typical characteristics are smooth, pointed penial verge and smooth inner penial wall.
