Alycaeus conformis is a species of small land snails with a gill and an operculum, terrestrial gastropod mollusks in the family Alycaeidae. [1]
The length of the shell attains 10 mm, its diameter 8.5 mm.
(Original description) The conical shell is very narrowly perforate and has a reddish apex. The lower whorls are either cream or suffused with pale pink. They are closely and finely obliquely striated. The larval whorls display similar striations, but in the opposite direction. There are 5 very convex whorls, with the body whorl inflated and constricted about 2 mm from the peristome. A breathing pore emerges at the start of the constriction and extends about half a whorl along the suture. The aperture is circular, with an expanded but non-reflected peristome, featuring an inner projecting rim. The operculum is concave, with approximately 6 whorls. [2]
This species occurs in Peninsular Malaysia.
Diplommatinidae is a family of small land snails, also known as staircase snails, with an operculum, terrestrial gastropod mollusks in the superfamily Cyclophoroidea. The Cochlostomatinae Kobelt, 1902, were previously considered a subfamily of the Diplommatinidae, but are now known to be a separate family.
Cyclophoridae is a taxonomic family of small to large tropical land snails with an operculum, terrestrial gastropod mollusks in the order Architaenioglossa belonging to the subclass Caenogastropoda.
Anostoma, common name the up-mouth snails, is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Odontostomidae. Snails in this genus are found in Brazil.

Aegista subchinensis is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusc in the family Camaenidae.
Plectostoma sciaphilum is an extinct species of land snail in the family Diplommatinidae. This species was originally found on a single limestone karst at Bukit Panching, in Peninsular Malaysia. In 2007, this karst was quarried, thus destroying the only known site of occurrence for this species. Plectostoma species are allopatric, being in found in dozens of isolated karst hills where few species occur, meaning that limited gene flow exists and only negligible hybridization occurs. Shell is distinctly convex, tuba shape similar to that of Plectostoma senex and P. turriforme, but this species lacks basal constriction teeth. Shell height: 2.6–2.9 mm, width: 1.5–1.6 mm.
Angustopila dominikae is a species of light grey, round, land snails, a terrestrial pulmonate gastropod mollusc in the family Hypselostomatidae. Angustopila dominikae have been found in southern China, and are considered to be one of the world's smallest terrestrial molluscs. This species is a tropical snail found on limestone cliffs.
Acmella nana is a species of land snail discovered from Borneo, Malaysia, in 2015. It was described by Jaap J. Vermeulen of the JK Art and Science in Leiden, Thor-Seng Liew of the Institute for Tropical Biology and Conservation at the Universiti Malaysia Sabah, and Menno Schilthuizen of the Naturalis Biodiversity Center in Leiden. It was named nana due to its minute size. Measuring only 0.7 millimeters in size, it is the smallest known land snail as of 2015. It surpasses the earlier record attributed to Angustopila dominikae, which is 0.86 mm in size, described from China in September 2015.

Alycaeus eydouxi is a species of small land snails with a gill and an operculum, terrestrial gastropod mollusks in the family Alycaeidae.
