description: SATSUMA LINI SP. NOV. (FIGS 11, 12)    Material examined   
 Type specimen: Holotype: TMMT 0602 (from type locality, dry shell, tissue in alcohol, dissected). Three paratypes: all from type locality, TMMT 0621 (immature, in alcohol); ANSP A21015 (shell with tissue in alcohol); BMNH 20060753 (dry shell).   
 Type locality   
Shanlinxi, Nantou County, central Taiwan (Fig. 1, Table 1)  
 Diagnosis   
 Shell and soft body white with grey pedal stripe; periphery angulated but not keeled; junction between columellar and inferior lips angulated. Because of a Description   
 Shell (Fig. 11): Dextral, conical, medium sized. Apex obtuse. Whorls inflated. Periphery bluntly angulated. Base expanded. Pre-apertural constriction behind outer and inferior lips present. Surface smooth, glossy with spiral striae. Shell colour whitish. Periostracum thin. Aperture diagonal, ovate-lunate, angulated between outer lip and inferior lip. Peristome thin, expanded, reflected at curved inferior lip. Superior columellar lip reflected. Umbilicus covered by columellar lip mostly, crevice-like. Columellar lip vertical to subvertical, angulated at junction with inferior lip.   
 Band or stain: Polymorphism exists in this taxon. The majority of individuals do not possess band or colour stain, and display a whitish coloration. A rare form exists with pink stain and smear from the third to the fourth band position. Band formula = 0 0 0 0 0 0 0 0; 0 0 (0 0) 0 0 0 0 (very rare).   
lack of knowledge of its genitalia, distinguishing this species from similar species based on shell characteristics only is difficult.  
 Etymology   
 L. lini: the name is dedicated to the late Professor Lin, Fei-Jan (1934–2004), a pioneering evolutionary biologist from Taiwan.   
 Reproductive system (Fig. 12): No reproductively mature specimens were collected. An immature genitalia is figured to demonstrate its basic configuration.   
 Distribution   
The species was found only in a narrow area of mid-altitude forest (1600–1800 m) near Shanlinxi, Nantou County, central Taiwan (Fig. 1, Table 1).  
 Remarks   
Inhabits typically above 3 m. Adults were found during winter (Fig. 11G). Only four specimens are available; two of these have adult shell morphology but genital development is incomplete. The other individuals are sub-adults.  
 This species is morphologically similar to S. albida, S. swinhoei sp. nov. and S. insignis, but its genetic relationship is closer to S. insignis (see Phylogeny). Compared with S. albida, S. lini has a larger, thinner and more rigid shell, higher spire and more oblique aperture. The species differs from S. swinhoei in having a periphery that is not keeled, smaller shell diameter and higher spire.
