) a chaetae that he considered intermediate between falciger and spiniger, to which he introduced the term “Pseudo- Grätenborste” or pseudo-spiny bristle. The term alluded to a strongly heterogomph chaetae, whose blade was a transition between falciger and spiniger forms. The blade is shorter than supra-acicular spinigers, but two or three times larger than those of falcigers. Also, the blade is as slender as those seen in spinigers, with the exception of having tapered tips which are not as pointed as in real spinigers (Augener 1933).

Chaetal shapes were differentiated by the length of blades and the degree of modification, and he used spinigers for all chaetae with long blades (San Martín 1991). Harris and Kudenov (1995) clarified that these chaetae really correspond to falcigers with long blades and used the same classification but based in the degree of modification more than length of blades.

San Martín (1992), attending these authors, proposed the term pseudospiniger to describe falcigers with elongated blades, homologous to the true spinigers of other polychaetes as the nereidids. Finally, since pseudospiniger appears in species without direct relationship and the division into subgenera is practical rather than scientific, he concludes that the character should not be used to distinguish between genera or subgenera (San Martín 2003).

The environment in which the specimens were collected is polluted by solid waste, mainly plastic and glass bottles and plastic bags. Many studies prove organic pollution in water and sediments in the bay due to the continuous discharges of urban waste and agricultural compounds from Hondo River, which flows into the bay (Álvarez-Legorreta 2009). Moreover, much of the mangrove forest area is deforested and the coast is transformed (Sánchez-Sánchez

In the new species, the determination of the position of falcigers with long blades is doubtful because in some occasions are postacicular position and in other preacicular; this problem was identified by Glasby (1999) in his cladistic analysis and he regarded all as preacicular for being more parsimonious than postacicular.

Hermaphroditism is considered a secondary reproductive condition among polychaetes. Several authors suggest that hermaphroditism is one of the adaptations for freshwater habitats and this condition is related to many factors such as body size population, density, difficult mate finding, isolated populations, habitat associations, and others (Aiyar & Subramanian 1936, Ghiselin 1969, Westheide 1984, Premoli & Sella 1995, Giangrande 1997, Puurtinen & Kaitala 2002, Prevedelli

by Johnson (1908). Initially the spotted pattern was confused with bunches of sperm as Johnson described, but after dissection bunches only appear in epithelial layers and not in coelom. Further, in chaetigers stained with hematoxilin and eosin testes or sperm cannot be recognized, and the same negative result was obtained after methyl-green staining.

of sequential hermaphroditism. In protandry males initially have a small body and become females after reaching a certain size; this is found in populations with clumped spatial distribution and living in mud increase the probability of this sexual strategy more than protogyny (Sella 2006). In this modality, a large body can produce more eggs than a smaller one, increasing the female fecundity and reproductive success; small males are preferred maybe for the low probability to change sex (Sella 2006). Therefore, this may explain the absence of males and why females tend to be larger than non-mature specimens. Consequently, the new species is considered gonochoric but the idea that it is hermaphrodite cannot be completely discarded.
