This species does not reproduce by epigamy, the typical condition in Eusyllinae, but rather by sexual stolons. Both male and female stolons are produced by schizogarníc scissiparity, a reproductive method previously reponed for Syllinae. The systematic position of this species is problematic, as it presents many morphological characters typical of Eusyllinae as well as a few of Syllinae. This paper redescribes Pionosyllis procera, and describes its stolons for the first time. Se redescribe Pionosyllis procera Hartman, 1965, c on base en un e levado número de ejemplares capturados en Cuba durante la "1 Expedición Cubano-Española"; también, se ha consultado la serie tipo. L a e specie t iene estolones reproductores, desconocidos hasta el presente. Su método reproductor (esquizogamía) es diferente al que le correspondería como perteneciente a la subfamilia Eusyllinae (epigamia), por l o que resulta necesario considerar su reubicación en Syllinae.
