levels of antibiotic activity during an annual cycle, and to try to establish some ecological relations
of this phenomenon. Monthly collections of sponges were made at Isla Espiritu Santo, Baja
California Sur, Mexico from May 1989 to June 1990. Bioassays of antimicrobial susceptibility
were carried out and densities of the associated organisms were recorded. Antibiotic activity levels
of the sponge correlated with inquilism level. Because antimicrobial activity was always found, we
believe that metabolites are produced continuously, although the sponge is probably able to change
the substance production mechanism in the presence of a particular stimulus. The massive
reproduction of the associated invertebrates and the arrival of large quantities of organisms over a
short time could be important stress factors for the sponge and a stimulus that modifies the
production of secondary metabolites.

This paper provides an overview of the serpulid species found in North America, as part of a broader study of fouling invertebrates focused on NIS (non-indigenous species) in United States coastal ecosystems. Almost 4400 serpulid specimens were examined from selected fouling plates. Fouling plates were deployed in 26 bays and coastal lagoons along the continental coasts of the United States and Hawaiian islands, primarily in bays and lagoons with salinities averaging 20‰ or greater. Twenty-fi ve serpulid species were identifi ed, including four new records for the United States (Ficopomatus uschakovi, Hydroides cf. brachyacantha, H. longispinosa and Protula longiseta), three known NIS, two presumed NIS, three cryptogenic serpulids, and several range extensions. Crucigera websteri extends its northward range from Santa Barbara Island to Humboldt Bay, California; Ficopomatus enigmaticus, fi rst recorded in North America from San Francisco, California in 1920, Rockport, Texas in 1952 and Barnegat Bay, New Jersey in 1980, is now recorded at additional localities on the east coast (Chesapeake Bay, Virginia, Charleston, South Carolina and Indian River, Florida) and the northern Gulf of Mexico (Galveston Bay, Texas); F. miamiensis extends its westward range from Louisiana to Texas; F. uschakovi, an Indo-Pacifi c and Western African species, was recorded formally for the fi rst time from the northern Gulf of Mexico (Galveston Bay and Corpus Christi, Texas) and the east coast of Florida (Jacksonville). Hydroides cf. brachyacantha extends its northward range from Curaҫao to Pensacola Bay, Florida; H. dirampha from Veracruz, Mexico to Corpus Christi, Texas; H. fl oridana extends its westward range from Louisiana to Texas; H. gracilis extends its northward range from Pacifi c Grove to San Francisco,

and 34 species respectively; however, most records come from the Gulf of California or the western coast of Baja California
Peninsula. Only a few records are from localities in the large expanse of the central and southern Mexican Pacific.
Thus, sabellids and serpulids were collected from several shallow water habitats along the coast of Mexican Pacific, such
as coastal lagoons, coral reefs, rocky shores and from man-made structures as marinas, piers and ships of several harbors;
additionally, specimens from national collections were revised. More than 8,400 specimens of sabellids and serpulids from
the states of Baja California, Baja California Sur, Sonora, Sinaloa, Michoacán, Guerrero, Oaxaca and Chiapas, and some
specimens from Panamá and Perú were examined. In the present work we record new localities of four sabellids and 24
serpulids. One sabellid, Branchiomma bairdi, is an exotic/invasive species in Oaxaca, Sinaloa and Baja California Sur,
while four species of serpulids are exotic and/or cryptogenic species: Ficopomatus uschakovi, Hydroides dirampha, H.
elegans and H. sanctaecrucis. Additionally, the geographical range has been extended for five species: the sabellids
Pseudobranchiomma punctata from Oahu, Hawaii to La Paz Bay, and Parasabella pallida from California to Puerto Escondido,
Baja California Sur; and for three serpulids, Hydroides inermis from the Galápagos Islands to Agua Blanca, Oaxaca,
H. gairacensis from Panamá to Puerto Ángel, Oaxaca, and H. panamensis from Panamá to Huatulco, Oaxaca and
Faro de Bucerías, Michoacán. Hydroides cf. amri, previously recorded as H. brachyacantha from Oahu, Hawaii, is more
similar to H. amri from Australia. The number of sabellids recorded for the Tropical Eastern Pacific increased to 33, the
serpulid species to 35.

Los primeros se realizaron principalmente por carcinólogos extranjeros desde mediados del siglo XIX, mientras que los investigadores mexicanos impulsaron el conocimiento desde el primer tercio del siglo XX. México cuenta con condiciones topográficas y
oceanográficas apropiadas para albergar una elevada diversidad de nichos y por lo tanto de crustáceos. Los registros de crustáceos de México han sido sintetizados por diversos autores mexicanos, por ello, esta contribución no pretende repetir esa información, sino poner en contexto toda la información generada, con el objeto de que sirva como base para
retomar el estudio sistemático de los crustáceos de México. El análisis de los datos apunta a que existe un conocimiento sesgado entre algunos taxones y regiones de México, pero también se observan varios problemas asociados como: la literatura especializada que en general esta dispersa, algunas fuentes clásicas aún son de difícil acceso para las nuevas generaciones de carcinólogos, las descripciones de las especies no están estandarizadas, la mayoría de los ejemplares tipo no se encuentran depositados en colecciones nacionales, los trabajos ecológicos no incluyen material testigo, etc. Hace falta explorar la totalidad de la riqueza de crustáceos de México a través de inventarios de grupos poco atendidos
(v.g., cirrípedos, peracáridos, ostrácodos, copépodos bénticos), de regiones poco conocidas (v.g., costa occidental de la península de Baja California, Pacífico central y sur de México, Caribe mexicano) y hábitats prioritarios (v.g., dulceacuícolas, cuevas, cenotes, arrecifes de coral, mar profundo). Por lo que se sugiere seguir estrategias como coordinar un
esfuerzo conjunto entre instituciones que cuenten con especialistas en crustáceos, para generar una base de datos de la carcinofauna mexicana, en donde se ponga a disposición la literatura especializada, generar nuevos recursos humanos en grupos en los cuales no haya expertos y, en lo posible, crear la apertura de plazas para que éstos jóvenes carcinólogos
sean contratados. Con estas acciones, a mediano plazo, se esperaría cubrir un mayor conocimiento de la carcinofauna de México, al menos en proporción similar al resto del mundo.

The exotic Indo-West-Pacific species, Ficopomatus uschakovi (Polychaeta, Serpulidae) is recorded ... more The exotic Indo-West-Pacific species, Ficopomatus uschakovi (Polychaeta, Serpulidae) is recorded for the first time in the Tropical Eastern Pacific from two sites in La Encrucijada Biosphere Reserve, Chiapas, a coastal lagoon in the Pacific south of Mexico. The means of dispersal of this serpulid species still remains unclear, as the nearest port (Puerto Chiapas) is 70 km to the south, and there are no port installations or shrimp cultures in the lagoon. The record of this serpulid species, apparently widely distributed in this coastal lagoon, has implications regarding possible effects on the brackish-water ecosystem, since the invasion event very well may have occurred several years ago. It is recommended that an exhaustive study be carried out in the coastal lagoons of Chiapas to evaluate the real distribution and the effects of this invasive species on the ecosystem. A complete description, including photographs and drawings, is provided.Se registra por primera vez la especie exótica del Indo-Pacífico occidental, Ficopomatus uschakovi (Polychaeta, Serpulidae), en el Pacífico oriental tropical, en dos sitios de la reserva de la biosfera La Encrucijada, Chiapas, una laguna costera en el Pacífico sur de México. El medio de dispersión de este serpúlido no es claro, debido a que el puerto más cercano (Puerto Chiapas) está 70 km al sur de la laguna, tampoco hay instalaciones portuarias ni estanques de cultivo de camarón. El registro de esta especie de serpúlido, aparentemente bien distribuida en esta laguna costera, tiene implicaciones con respecto a posibles efectos sobre el ecosistema salobre, sobretodo considerando que el evento de invasión pudo suceder hace ya varios años. Se recomienda realizar un estudio exhaustivo en las lagunas costeras de Chiapas para evaluar la distribución real y los efectos de esta especie invasora en el ecosistema. Se incluye una descripción completa, con fotografías e ilustraciones de la especie.

Serpula madrigalae sp. n. from the Turks and Caicos has a tube with five longitudinal ridges, four rows of alveoli and a medium-sized shallow symmetrical opercular funnel with 17 radii, and an inner surface with opercular tubercles. Serpula vossae sp. n. from the Western Caribbean and Bahamas has a tube with 6–8 longitudinal ridges, and a large, deep symmetrical opercular funnel, with 21–33 radii, and a smooth inner surface. Serpula cf. vermicularis, recorded from the Gulf of Guinea (tropical eastern Atlantic), is distinguished from the nominal species in possessing fewer opercular radii (33–39) and the lack of a proximal rasp in the bayonet chaetae; tubes are missing. The distribution range is extended for the three known Spiraserpula species found in the collections, Spiraserpula caribensis, Spiraserpula karpatensis and Spiraserpula ypsilon.
