Type locality: South Laos , Salavan Province , near Ban Donxé Village, E bank of Se Don River. Material examined LAOS : Dextral, holotype ( RMNH 98143, Fig. 4 H ); 4D shells, paratypes ( RMNH 98144). Remarks No specimen was found in this survey. Amphidromus protania has a very similar shell shape to that the dipterocarp forest species A. givenchyi . The genitalia contain a long and coiled proximal part of the epiphallus, with a relatively short appendix, as in A. givenchyi ( Lehmann & Maassen 2004 ; Sutcharit & Panha 2006 ). However, the characters distinguishing it from A. givenchyi are the relatively smaller shell (height 26–31 mm in A. protania ; Table 1 ), the yellowish shell color as well as the brownish subsutural and spiral bands on the periphery. Moreover, Lehmann & Maassen ( 2004 ) mentioned that the brownish banding pattern had less variation. However, a brownish spiral band on the periphery can also be observed in juvenile A. givenchyi (see Sutcharit & Panha 2006 : fig. 4o). Moreover, this species occurs in dipterocarp forest within the range of A. givenchyi ; therefore, it is possibly a shell color variant of A. givenchyi . Additional specimens for further anatomical and molecular study are desirable to test this hypothesis.
