A reevaluation and redescription of the branchiobdellidan Sathodrilus tetrodonta (Pierantoni, 1906) new comb. (Annelida: Clitellata)
Research article published in Zootaxa (2024)
Abstract
The questionable status of Branchiobdella tetrodonta Pierantoni, 1906 is resolved and the species is transferred to the correct genus. The original description was made from specimens removed from signal crayfish collected in California, USA, unfortunately, Pierantoni (1906c) did not designate any type specimens nor where the preparations were deposited; they are now presumed lost. Holt (1967) believed B. tetrodonta possessed unique penial hooks and a chitinous sheath which was due to his mistranslation of the original Italian description. As a result, Sathodrilus attenuatus Holt, 1981, was described even though specimens came from the same area and host and possessed very similar jaw characteristics to B. tetrodonta. In addition, the jaw characteristics of both endemic species are unique in the Pacific Ocean drainage of the USA. A reassessment of the literature and re-examination of Holts type specimens has resulted in the species name becoming a new combination, Sathodrilus tetrodonta (Pierantoni, 1906), with Sathodrilus attenuatus Holt, 1981, as its junior synonym.

Resumen
The questionable status of Branchiobdella tetrodonta Pierantoni, 1906 is resolved and the species is transferred to the correct genus.
Por qué esto importa para la hirudoterapia
Este estudio taxonómico resuelve el estatus nomenclatural de *Branchiobdella tetrodonta* Pierantoni, 1906, transfiriéndolo al género *Sathodrilus* y estableciendo *Sathodrilus attenuatus* Holt, 1981 como su sinónimo junior. La reevaluación se basó en el reexamen de los especímenes tipo de Holt y de la bibliografía, corrigiendo una traducción histórica errónea de la descripción original italiana relativa a los ganchos peniales. El organismo es un branchiobdélido asociado al cangrejo de señal en California. Este artículo solo resulta relevante para la taxonomía y sistemática de los branchiobdélidos dentro de los anélidos; no guarda relación con la hirudoterapia, la aplicación terapéutica de sanguijuelas ni con el secretoma de la sanguijuela. Su única relevancia para ASH es como contribución a la taxonomía más amplia de invertebrados, sin implicaciones terapéuticas.
