This dataset contains the digitized treatments in Plazi based on the original journal article Salazar-Vallejo, Sergio I., Piotrowski, Christina N., Gustav, Leslie Harris, Paulay, Gustav (2025): Revision of Pherecardia Horst 1886 (Annelida Amphinomidae).

ABSTRACT
Amphinomid annelids are classified after the shape of caruncle, the presence and type of branchiae along body segments, and the type of chaetae present. Pherecardia Horst, 1886 was proposed to include species having a large caruncle with a heart-shaped median ridge and lateral lobes. However, generic delineation was not well understood at the time, and some species currently referred to the genus were described in Hermodice Kinberg, 1857 and Amphinome Bruguière, 1789. Pherecardia currently includes four shallow water species: P. maculata Imajima, 2003 from Japan; P. parva Monro, 1924 from the Macclesfield Bank; P. polylamellata de Silva, 1961 from Sri-Lanka; and P. striata (Kinberg, 1857) from the French Polynesia.Two other species have also been proposed as congeneric: A. bruguieresi de Quatrefages, 1866; and A. formosa de Quatrefages, 1866. The genus is best known for its type species, Pherecardia striata (Kinberg, 1857), a common and widespread, large and readily recognized species characterized by numerous longitudinal dorsal pigmented stripes and recorded across the Indo-Pacific from East Africa to the East Pacific. This species has been regarded as relevant for coral reef ecology since it attacks injured predatory crown-of-thorns starfish (Acanthaster planci (Linnaeus, 1758)). Here we review the genus based on examination of type and additional material from 10 museum collections and mitochondrial DNA comparisons of representative specimens from various localities. We recognize three species: P. striata, P. distincta (Hoagland, 1920) (new combination, including P. polylamellata as synonym), and P. maculata (retained pending the study of topotypical specimens). Pherecardia parva is transferred to Pherecardites Horst, 1912 and renamed as Pherecardites monroi because of homonymy with Pherecardites parva Horst, 1912. Amphinome bruguieresi is regarded as a junior synonym of Eurythoe indica (Schmarda, 1861); the status of A.formosa cannot be determined. Keys are included for species of Pherecardia and Pherecardites.
RÉSUMÉ
Révision de Pherecardia Horst, 1886 (Annelida, Amphinomidae).
Les annélides polychètes amphinomidées sont classées en fonction de la forme de leur caroncule, de la présence et du type de branchies le long des segments du corps, et des types des soies présents. Pherecardia Horst, 1886 a été proposé pour inclure les espèces ayant une grande caroncule avec une bordure médiane en forme de coeur et des lobes latéraux. Cependant, la définition générique n’était pas bien comprise à cette époque, et certaines espèces actuellement référencées dans ce genre ont été décrites dans Hermodice Kinberg, 1857 ou dans Amphinome Bruguière, 1789. Pherecardia inclut actuellement quatre espèces d’eau peu profonde: P. maculata Imajima, 2003 du Japon, P. parva Monro, 1924 du banc Macclesfield, P. polylamellata de Silva, 1961 du Sri-Lanka, et P. striata (Kinberg, 1857) de Polynésie française. Deux autres espèces ont aussi été proposées comme congénères: A. bruguieresi de Quatrefages, 1866 et A. formosa de Quatrefages, 1866. Le genre Pherecardia est mieux connu pour son espèce type, P. striata (Kinberg, 1857), une espèce commune, largement répandue et aisément reconnaissable, caractérisée par les nombreuses rayures pigmentées dorso-longitudinales et recensée dans tout l’Indo-Pacifique, de l’Afrique de l’Est au Pacifique Est. Cette espèce a été considérée comme importante pour l’écologie des récifs de corail, car elle s’attaque aux étoiles de mer “couronne d’épines” (Acanthaster planci (Linnaeus, 1758), quand celles-ci sont blessées. Nous révisons ici le genre sur la base de l’examen du matériel type et de matériel supplémentaire provenant de dix collections muséales, ainsi que de comparaisons d’ADN mitochondrial de spécimens représentatifs provenant de diverses localités. Nous reconnaissons trois espèces: P. striata, P. distincta (Hoagland, 1920) (nouvelle combinaison, incluant P. polylamellata comme synonyme), et P. maculata (conservée en attendant l’étude des spécimens topotypiques). Pherecardia parva est transférée à Pherecardites Horst, 1912 et renommée Pherecardites monroi en raison de l’homonymie avec Pherecardites parva Horst, 1912. Amphinome bruguieresi est considéré comme un synonyme junior d’ Eurythoe indica (Schmarda, 1861); le statut de A. formosa reste indéterminé. Des clefs sont incluses pour les espèces de Pherecardia et Pherecardites.
