7 Blade of paramere without apical spine with apex narrowly roundish, inner margin distinctly wavy with prominent depression on upper outer margin; 1stgonocoxae on posterior margin distinctly depressed at anterior angle; spermathecal
bulb with two finger-like processes .
Abbreviations: CDS, common duct of the spermatheca (copulatory canal); SPDU, spermathecal
duct (bursa duct); SP, spermatheca (bursa copulatrix); TOT, total length of CDS 4- SPDU + SP; SPD, spermathecal
diverticulum (bursa tract diverticulum); VA, vagina; FO, free oviduct; EPC, epiphallic cecum; SWEP, single-walled section of epiphallus (proximal region); DWEP.
Female: cibarium with about 12 horizontal small triangular teeth, one row of about 6 large vertical teeth and other row below of about four less differentiated teeth; arch complete but less visible at middle; spermathecae spherical smooth, without differentiated wide neck at the union with the individual spermathecal
duct; individual spermathecal
ducts as long as the furca stem and nearly inexistent common duct (Ibanez-Bernal 2002).
Head nearly parallel-sided, almost rectangular,apex broad anterior part of lateral margins of head with 4-6 irregular-shaped but distinct dentine; lateral margins of pronotum with eleven unequal long acute spines; margins of connexivum with comb-like thin spines of equal length; dorsoposterior cavity of male pygophore with small conical median projection, ventroposterior cavity shallow with broad roundish median excavation and triangular lobes on sides; spermathecal
bulb with three processes, one short, highly sclerotized, a second a little longer, semi-sclerotized and a little bent at apex, and the third thick, very long, reaching middle of first flange M.
chaetae trivial (nib-shaped, distal portion with parallel edges, not twisted).
Genitalia: Dorsal labiate plate without sclerotized rings, with two distinct sclerotized bands, spermathecal
gland placed near posterior margin (Fig.
stalk has a globular lateral lobe and an oblong and often bilobed terminal chamber (Fig.
New Fabriciola species (Polychaeta, Sabellidae, Fabriciinae) from eastern Atlantic, with a description of sperm and spermathecal
All species seem to have a dorsal tube on the bursa copulatrix which is the origin of the spermathecal
duct, of a much more rigid consistency than the membranous and amorphous and generally much-pleated bursa, differing from what we have seen in other species (Bentos-Pereira 1998, BentosPereira & Rowell 1999).
During copulation the flagellum is threaded up the female's long and convoluted spermathecal
duct and into the ampulla and occasionally also into the spermatheca.
contents were examined under a compound microscope at 400x magnification.
Epigyne with globular, posteriolateral, diverging spermathecal
ducts coil inward; epigynal orifices thin, ovoid, at posterior margin; epigynal plate narrow and projected anteriorly, narrow and scape like posteriorly.
