Souza, Pedro Mendes De, Rossi, Mariana Fonseca & Dias, Roberto Júnio Pedroso, 2024, Systematic review of the genera Rhabdostyla Kent 1880 and Orborhabdostyla Foissner et al. 2010 (Ciliophora, Peritrichia, Epistylididae), Zootaxa 5399 (3), pp. 201-230 : 211

Genus: Rhabdostyla Kent, 1881

Opisthostyla Stokes, 1886 b: 565 .

[ Rhabdostyla ] ( Rhabdostyla ) Kent, 1881 — Kahl, 1935: 673

[ Rhabdostyla ] ( Opisthostyla ) Stokes, 1886 b— Kahl, 1935: 679

Epistylis (Rhabdostyla) Kent, 1881 — Stiller, 1971: 64

Diagnosis: Solitary, with a short, non-contractile peduncle, with a generally bell-shaped body and a well-defined peristomial collar.

Type specie: Epistylis spheroides (Subsequent designation Jankwoski, 2009)

Remarks: initially described by Kent in (1881) as solitary “animalcules”, similar to those of the genus Vorticella , but with non-contractile peduncle. In a recent taxonomic study, Álvarez-Campos et al. (2014) defines the genus as solitary peritrich ciliates with short non-contractile peduncles, with a mainly bell-shaped body and a well-defined peristomial lip. Here we suggest Opisthostyla annulate as type species of Opisthostyla , this species was in the original genus description, have a decent diagnosis and attached graphic representation.
