Maizaniella sapoensis is a species of land snail with an operculum, a terrestrial gastropod mollusk in the family Maizaniidae.
The specific name sapoensis is named after Sapo National Park, Liberia, where it lives. [1] The species is provisionally attributed to the subgenus Spirulozania on account of the conspicuous spiral sculpture. [1] Type material is stored in the National Museum of Natural History, Leiden (Rijksmuseum van Natuurlijke Historie). [1]
Distribution of Maizaniella sapoensis include Liberia and it is only known from the type locality, 5°20′N8°47′W / 5.333°N 8.783°W . [1]
She shape of the shell is high-spired in comparison with other Maizaniella species. The color of the periostracum is pale yellow-brown. The shell has three whorls. The sculpture is regularly curved, with thin axial ribs (about 20 on the third whorl) and with fine spiral threads. The aperture is large and circular, about 1 mm in diameter. The umbilicus is narrow. [1]
The size of the shell is extremely small (about 2.1 mm wide at three whorls). The width of the shell is 2.05-2.3 mm. The height of the shell is from 1.88 m to estimated 2.1 mm.

It was recorded in a floor litter from higher spots in a swampy area in wet undisturbed lowland rainforest (evergreen forest) at altitude 140 m. [1]
The gastropod shell is part of the body of a gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group.
