Sternites. In males, sternite VI with mesoventral spinous lobe and sternite VII with shorter mesoventral spinous lobe. Sexually dimorphic females with similar lobes, but only on sternites V and VI ( Schmid 1989).

Male genitalia. Segment IX in lateral view with sclerotization long ventrally and laterally, attenutated and mostly membranous dorsally except for internal costa supporting entire anterior circumference, also often with longitudinal internal ventrolateral costae ( Schmid 1989). Parapods compressed (laterally flattened) and in horizontal bands, relatively long, wide or narrow, straight or sinuous, simple or complex, spineless, spinose or setose ( Schmid 1989). Filipods sometimes absent, emerging mesoventral of preanal appendages, elongate or short ( Ross & King 1952). Preanal appendages always present at anterolateral margins of segment X and button-shaped, rounded or elongate, frequently covered by stout setae ( Ross & King 1952). Inferior appendages each twosegmented, long, slender, with well developed second article located at apex of first article, often beside apicomesal projection of first article ( Schmid 1989). Proctiger large and slightly differentiated, forming dorsal flange ( Schmid 1989). Phallic apparatus incomplete, without parameres; phallotheca cylindrical, frequently rounded anteriorly with posterior apex located between parapods, composed of two sclerotized, compressed beaks (“becs de la phallothèque” of Schmid 1989) with different shapes, with membranous endotheca arising between them, this endotheca may be simple or with spines or branches ventrally, laterally or dorsally; aedeagus (“phalicata” of Ross 1956) arising from endotheca, stylet-like, compressed (laterally flattened), arched generally ventrad and then caudad, but with different specific forms; thick tenon from ventrobasal portion of phallotheca articulating with basomesal corners of inferior appendages ( Schmid 1989).
