Figure 8 Holotype . Malaysia , Sabah , Tawau Province , Batu Baturong c. 50 km W.S.W. of Lahad Datu (leg. J.J. Vermeulen & H. Duistermaat , RMNH.5003952 ). Description. Shell minute, rather thick, about opaque, pale corneous. Surface shiny. Spire conical with approx. flat or slightly concave sides, apex somewhat narrowly obtuse, whorls moderately convex. Sculpture consisting of radial ribs intersecting with about equally strong spiral threads, creating a pattern of rounded, sharply delineated depressions on the shell surface; locally this pattern is distorted, and around the periphery and below the suture the depressions more or less line up parallel to the growth lines; close to the aperture radial riblets and growth lines predominate. Aperture widely and obliquely ovate in outline, with a slightly concave parietal side, transition from parietal to basal side obtusely angular. Peristome thickened, with a slight lip on the inner side. Umbilicus open, narrow. Dimensions. Height c. 1.75 mm; width c. 1.45 mm; h/w c. 1.25; number of whorls c. 5; height aperture c. 0.80 mm; width aperture c. 0.70 mm. Habitat in Sabah and distribution. Primary forest on limestone soil, at 100-300 m alt. Sabah: East coast, Baturong Hill. Also in Kalimantan Timur. Endemic to Borneo. Cross diagnosis. The sculpture uniquely identifies the species among the Sabah snail fauna. Anaglyphula sauroderma shares the irregularly cancellate sculpture, with shallow pits, with Anaglyphula cancellata Rensch, 1932, from Flores. It differs in having a higher spire (distinctly higher than wide) and evenly rounded whorls. Etymology. The name refers to the shell surface [sauros (Gr.) = lizard; derma (Gr.) = skin].
