Richmond River Keeled Snail
Thersites richmondiana
Thersites richmondiana is a species of large, air-breathing land snail, a terrestrial gastropod mollusc in the family Camaenidae. It is native to eastern Australia and is the type species of the genus Thersites.
A 2025 taxonomic revision of Thersites, integrating genome-scale molecular data and morphological characters, retained T. richmondiana as a distinct species and treated Thersites darlingtoni as its junior synonym.

Description
Thersites richmondiana has a closed umbilicus and an angulated shell periphery. Shell height ranges from 35.4 to 54.6 mm and shell width from 48.6 to 81.9 mm, with a shell height-to-width ratio of 0.55–0.89. In most examined specimens, the tip of the flagellum is blunt. The flagellum measures 5.1–16.7 mm, while the distal portion of the epiphallus measures 11.0–24.2 mm. The shell is generally large and depressed to globose, with a conspicuously angulated or keeled body whorl.
Range & habitat
Thersites richmondiana occurs in subtropical eastern Australia, principally in north-eastern New South Wales and south-eastern Queensland. Its documented localities include the Richmond River region, Mount Tamborine and the MacPherson Ranges. Following the synonymization of T. darlingtoni, populations formerly assigned to that species are included within the distribution of T. richmondiana.
