Cathaica pyrrhozona is a species of air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Camaenidae, which is similar to Cathaica fasciola on shell morphology. [1] [2] But this species has single proximal accessory sac instead of two.

Taxonomy

This species was described under the name Helix pyrrhozona by German–Chilean paleontologist and zoologist Rodolfo Amando Philippi in 1845.

Distribution

This species was considered as synonym of Cathaica fasciola which was considered as widely distributed in China. [3] [4] However, Zhang and Wade (2023) [2] found that Cathaica fasciola and Cathaica pyrrhozona are two different species.

Description

The shell is same with Cathaica fasciola, [2] thin, [5] but solid. [4] The color of the shell is white, rather opaque, with a broad chestnut-brown band at the periphery, and a faint brownish band below the suture. [4] The shape of the shell is depressed above and below. [4] The spire is low-conoid. [4] The surface is shining, sculptured above with close rib-striae, becoming more delicate below. [4] The shell has 5½ whorls. [5] [4] The earliest whorl is smooth, shining, forming a subacute apex. [4] Following whorls are slightly convex, slowly increasing, separated by an impressed suture. [4] The last whorl is much wider, rounded at the periphery, hardly descending in front. [4] Aperture is slightly oblique, lunate-oval. [4] Peristome is white and thickened with a strong white lip. [5] [4] The umbilicus is rapidly narrowing to a narrow, deep perforation. [4] The width of umbilicus is one-eighth the greatest diameter. [4]

The width of the shell is 15 mm (0.59 in). [5] [4] The height of the shell is 8.5 mm (0.33 in). [4]

Digestive system: radula and jaw was depicted by George Washington Tryon and Henry Augustus Pilsbry in 1894. [6]

Reproductive system: penis is slender, ending in a long retractor and the terminal vas deferens. [6] Dart sac is large, opening into atrium. [6] There is a dense cluster of about ten club-shaped, glandular mucus glands near the atrium base. [6] Spermatheca duct is long. [6] Only one proximal accessory sac is found which let this species distinguished from C. fasciola [2]

Stylommatophora is an order of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This taxon includes most land snails and slugs. Stylommatophorans lack an operculum, but some close their shell apertures with temporary "operculum" (epiphragm) made of calcified mucus. They have two pairs of retractile tentacles, the upper pair of which bears eyes on the tentacle tips. All stylommatophorans are hermaphrodites.

Amphidromus is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Camaenidae. The shells of Amphidromus are relatively large, from 25 mm (0.98 in) to 75 mm (3.0 in) in maximum dimension, and particularly colorful. During the 18th century, they were among the first Indonesian land snail shells brought to Europe by travelers and explorers. Since then, the genus has been extensively studied: several comprehensive monographs and catalogs were authored by naturalists and zoologists during the time period from the early 19th to the mid 20th centuries. Modern studies have focused on better understanding the evolutionary relationships within the group, as well as solving taxonomic problems.
