Diagnosis

( Molina-Acevedo and Carrera-Parra 2017, Paxton 2009, Salazar-Vallejo and Carrera-Parra 1997): Prostomium divided into two lobes, with two eyes and five smooth antennae (with brown perpendicular bands). Jaws eulabidognath-type (asymmetrical, posterior parts dentate to Mithraculus forceps -like, short carriers). Formula (maxillae): 1+1, 3 to 4+4, 5+0, 5+6 and 1+1. Peristomial cirri absent (Fig. 3 b). Ramified branchiae (1 to 4 filaments) from chaetiger 19. Notopodial cirri (longer than neuropodial ones) enlarged in anterior chaetigers, digitiform in posterior chaetigers. Neuropodia carry anterior acicular lobe rounded, posterior ones triangular; anterior globular basally cirri larger than posterior ones; pre- and post-chaetal lobes; limbate, pectinates and falcigers chaetae; 1-3 dark aciculae by chaetiger and dark subacicular unidentate hooks.
