A new species of <i>Paraeupolymnia</i> Young and Kritzler, 1986 (Polychaeta, Terebellidae) from Brazil

Abstract

SUMMARY: A new species of the previously monotypic Paraeupolymnia found in large numbers in biogenic structures such as algae, oyster shells, and sabellariid reefs on rocky shores in the State of São Paulo is described here. Paraeupolymnia uspiana is characterised by the absence of both lateral lappets on anterior segments and pigmentation on buccal tentacles, and by the eyespots, which are larger and more numerous than those of P. carus, the type species of the genus. The diagnosis of Paraeupolymnia is emended, based on features of both species, after the analysis of Brazilian material and the holotype of P. carus. It is suggested that, after a comprehensive phylogenetic analysis of the group is undertaken, Paraeupolymnia will most probably be synonymised with Eupolymnia.Key words: Polychaeta, Terebellidae, Terebellinae, Paraeupolymnia, State of São Paulo, Brazil.

Paraeupolymnia uspiana se caracteriza por no presentar lamelas laterales en los segmentos anteriores ni pigmentación en los tentáculos bucales y por tener ocelos mayores y más numerosos que los de P. carus, la especie tipo del género. Se modifica la diagnosis de Paraeupolymnia basándose en características de ambas especies, después del análisis del material brasileño y del holotipo de P. carus. Se sugiere la posibilidad de que un futuro análisis filogenético sinonimi-

The Terebelliformia-Recent Developments and Future Directions

“…Finally, the years 2000-2019 were the most prolific, with 258 species described by 38 different first authors (Figure 4). Among them, Hutchings, Nogueira and Carrerette were the most productive taxonomists (Table 1), with descriptions of 85 species of Terebellidae s.l., mostly from Brazil and Australia (e.g., [32][33][34][35][36][37][38][39][40]); Ampharetidae were also well studied during this period, with 32 species described [41][42][43].…”
