New Prionospio and Laubieriellus (Annelida: Spionidae) species from Southeastern Brazil

Zootaxa, 2019
Two new Prionospio species—Prionospio solisi sp. nov. and Prionospio nonatoi sp. nov. and a new Laubieriellus species—Laubieriellus decapitata sp. nov. are described from Espírito Santo Basin, Southeast Brazil. For both Prionospio species, branchial pattern differed from the genus diagnosis, which is therefore emended.

A New Species of the Spionidae (Polychaeta) with Asexual Reproduction Associated with Sponges

Zoologica Scripta, 1985
Polydorella smurovi sp.n. is described from an underwater coral bank near the Dachlak Archipelago (Red Sea). This new species has alternating sexual and asexual (paratomy) reproduction, short caruncle, specialised broom‐like setae on segment 5 and capillary setae in the neuropodia of the same segment.

Palp morphology in two species of Prionospio (Polychaeta: Spionidae)

Hydrobiologia, 2003
The palp morphology of Prionospio fallax Soderstrom, 1920 from Sweden and Prionospio cf. saldanha Day, 1961 from Thailand was examined with a scanning electron microscope. Prionospio fallax was also studied in vivo using light-microscopy. Both species have grooved feeding palps, adorned with up to five ciliary characters: frontal cilia, transverse ...

Secondary production ofPrionospio caspersi (Annelida: Polychaeta: Spionidae)

Marine Biology, 1990
The annual somatic production ofPrionospio caspersi Laubier was estimated, between July 1986 and 1987, at a sandy shallow-bottom station in the area facing the Po River Delta, Italy, where this species is one of the most abundant. Primary recruitment occurs in summer, and maturation of gametes the following spring.

Life History Patterns of Polychaete Species of the Family Spionidae

Journal of the Marine Biological Association of the United Kingdom, 1985
The reproductive morphology and larval development in Spionidae has been dealt with extensively by Soderström (1920), Hannerz (1956), Orrhage (1964). Simon (1967), Blake (1969) and Rice (1980). The family shows a considerable variation in gamete morphology, modes of sperm transfer and types of larval development.
