Redescriptions of Nereis oligohalina (Rioja, 1946) and N. garwoodi González-Escalante

&

Salazar-Vallejo, 2003 and description of N. confusa sp. n. (Annelida, Nereididae)

Víctor Manuel Conde Vela (2015)

Resumen en inglés: "Type material of several polychaete species described by Enrique Rioja from Mexican coasts are lost, and the current status of some species is doubtful. Nereis oligohalina (Rioja, 1946) was described from the Gulf of Mexico, but it has been considered a junior synonym of N. occidentalis Hartman, 1945, or regarded as a distinct species with an amphiamerican distribution. On the other hand, N. garwoodi González-Escalante & Salazar-Vallejo, 2003, described from Chetumal Bay, Caribbean coasts, could be confused with N. oligohalina. In order to clarify these uncertainties, N. oligohalina is redescribed based on specimens from the Mexican Gulf of Mexico, including a proposed neotype; further, N. garwoodi is redescribed including the selection of lectotype and paralectotypes, and N. confusa sp. n. is described with material from the Gulf of California. A key for the identification of similar species and some comments about speciation in nereidid polychaetes are also included. "

Revision of Hermodice Kinberg, 1857 (Polychaeta: Amphinomidae)

Revisión del género Hermodice Kinberg, 1857 (Polychaeta: Amphinomidae)

beatriz yáñez (2011)

Resumen en español: "El género Hermodice Kinberg, 1857 se estableció con la especie Aphrodita carunculata Pallas, 1766, debido a la forma y desarrollo de la carúncula. Posteriormente, se describieron varias especies dentro del género. Sin embargo, actualmente se considera que el género es monotípico y que H. carunculata es una especie cosmopolita. La revisión de material tipo y especímenes adicionales, incluyendo ejemplares vivos, nos ha permitido redefinir las características diagnósticas e incorporar dos nuevos atributos: el número de filamentos branquiales y el lóbulo anal. Como consecuencia, ha sido posible confirmar las diferencias entre Hermodice y Pherecardia Horst, 1886. Así mismo, se redescribe la especie tipo H. carunculata y se reestablece H. nigrolineata Baird, 1870. Además, H. formosa (Quatrefages, 1866) se transfiere a Pherecardia, junto H. pennata Treadwell, 1906 y H. distincta Hoagland, 1920. "

Elisesione, a new name for Wesenbergia Hartman, 1955, and the description of a new species (Annelida, Hesionidae)

Sergio I. Salazar Vallejo (2016)

Resumen en inglés: "Wesenbergia Hartman, 1955 (Annelida, Hesionidae) is both preoccupied and a junior homonym of Wesenbergia Kryger, 1943 (Hymenoptera, Pteromalidae), and must be renamed. Elisesione nom. n. is proposed as a replacement name, derived from the combination of the first name of the discoverer, Elise Wesenberg-Lund, and Hesione Savigny in Lamarck, 1818. Elisesione mezianei sp. n., is described from the Wallis and Futuna islands (southwest Pacific). A key to separate E. mezianei sp. n. from its congener E. problematica (Wesenberg-Lund, 1950) is included; further, the record of E. problematica for Japan should be regarded as a distinct species because it has palps shorter than antennae (subequal in the type species), and shorter neurochaetal blades (7–9 times longer than wide vs 8–12 times longer than wide in the type species).

Revision of Ilyphagus chamberlin, 1919 (Polychaeta, Flabelligeridae)

Sergio I. Salazar Vallejo (2012)

Resumen en inglés: "Ilyphagus Chamberlin, 1919 includes abyssal, fragile benthic species. Most species have large cephalic cages but chaetae are brittle and easily lost which may explain why the original definition included species with a cephalic cage or without it. The type species, Ilyphagus bythincola Chamberlin, 1919, together with another species (Ilyphagus pluto Chamberlin, 1919) were described as lacking a cephalic cage whereas a third species (Ilyphagus ascendens Chamberlin, 1919) was described with one. To clarify this situation, all available type and non-type materials were studied. Ilyphagus is redefined to include species with digitiform bodies, abundant filiform papillae and a thin body wall; their neurochaetae are thick, anchylosed aristate spines, and all species have a cephalic cage (in the type species the presence of a cage is inferred from the remaining chaetal scars). Ilyphagus pluto, which also lacks a a cephalic cage is determined here to be a holothurian. The redefined genus contains Ilyphagus bythincola (incl. Ilyphagus ascendens), Ilyphagus coronatus Monro, 1939, Ilyphagus hirsutus Monro, 1937, and Ilyphagus wyvillei (McIntosh, 1885). "
