Genus: Plectostoma

Name

Plectostoma umbilicatum Liew, Thor-Seng, 2014Wikispecies linkPensoft Profile

Diagnosis

Diagnosis. Shares with Plectostoma dindingensis, Plectostoma mengaburensis, and Plectostoma panhai the tuba form, but differs by having an oblong conical apical spire.

Description

Description. Apex. Shape: moderately convex. Spire. Height: 2.0-2.3 mm. Width: 1.3-1.5 mm. Number of whorls: 4 5/8-4 3/8. Apical spire shape: oblong conical. Basal spire shape: ovoid. Whorl periphery: distinctly convex. Umbilicus: completely open or partially closed by tuba. Constriction. Parietal teeth: none. Basal teeth: none. Tuba. Coiling direction: type 1 and aperture visible from back view. Tuba whorl length in proportion to spire last whorl: ca. 1/2-3/4. Proportion of tuba that attaches to spire: whole. Aperture and peristome. Peristome: double peristomes. Outer peristome shape: same as inner peristome and uniformly projected all around, except the posterior part. Spiral lines. Thick lines: present. Thin lines: present. Radial ribs. Rib density: 6-9 ribs per mm. Rib intensity: thin. Shape: straight. Inclination: orthoclin.

Distribution

Distribution. Type locality. Limestone hill cluster named Kota Tongkat (3°53'28"N, 102°28'23"E). Distribution range. It is only known from the type locality. All other adjacent limestone outcrops have been sampled, but only other Plectostoma species were found (Figure 18D).
