Pseudostomatella
A genus of small sea snails in the top snail family.
Pseudostomatella is a genus of small marine gastropods belonging to the top snail family Trochidae, within the subfamily Stomatellinae. These sea snails are found across a broad geographic range, including the central and eastern Indian Ocean, the Indo-Malaysian region, and waters off Australia. The genus includes numerous species, such as *Pseudostomatella baconi*, *P. clathratula*, *P. coccinea* (with a form *flammulata*), *P. cycloradiata*, *P. decolorata*, *P. erythrocoma*, *P. martini*, *P. orbiculata*, *P. papyracea*, and *P. selecta*. Some former members have been reassigned: *Pseudostomatella maculata* is now considered a synonym of *Granata maculata*, and *Pseudostomatella rubra* is a synonym of *Stomatolina rubra*. Additionally, several taxa remain unresolved, including *Pseudostomatella decorata*, *P. monilifera*, and *P. splendidula*.

Lore & Background
The genus Pseudostomatella belongs to the subfamily Stomatellinae within the family Trochidae, commonly known as top snails. The article lists several species, including Pseudostomatella baconi, Pseudostomatella clathratula, Pseudostomatella coccinea (with a form Pseudostomatella coccinea flammulata), Pseudostomatella cycloradiata, Pseudostomatella decolorata, Pseudostomatella erythrocoma, Pseudostomatella martini, Pseudostomatella orbiculata, Pseudostomatella papyracea, and Pseudostomatella selecta. Some species have been brought into synonymy, such as Pseudostomatella maculata (synonym of Granata maculata) and Pseudostomatella rubra (synonym of Stomatolina rubra). Additionally, three taxa are listed as inquirenda: Pseudostomatella decorata, Pseudostomatella monilifera, and Pseudostomatella splendidula, indicating unresolved taxonomic status.
Reader's Guide
The significance of Pseudostomatella lies in its wide distribution across the Central and East Indian Ocean, Indo-Malaysia, and off Australia, reflecting its ecological adaptability within marine environments. As a member of the Trochidae family, it contributes to the diversity of top snails. The article notes taxonomic uncertainties, including species brought into synonymy and taxa inquirenda, highlighting ongoing scientific debate about species boundaries. The genus is referenced in works such as Vaught's classification of living Mollusca and Higo, Callomon & Goto's catalogue of marine shell-bearing Mollusca of Japan, indicating its inclusion in systematic malacology. The presence of a named form (Pseudostomatella coccinea flammulata) suggests intraspecific variation recognized by some authors. The genus's legacy is tied to its role in understanding gastropod diversity and biogeography in tropical Indo-Pacific waters.
