Addendum to the Checklist of the helminth parasites of vertebrates in Costa Rica.

In this work, we present an addendum to the "Checklist of the helminth parasites of vertebrates in Costa Rica" with a parasite-host list as well as a host-parasite list. This addendum updates the available information on this group of parasites in Costa Rica, since very recently a new input has been made to describe the helminth fauna of vertebrates, particularly at the Area de Conservacion de Guanacaste. In this paper, we add 33 records, representing 23 species. This raises the number of helminth species described in vertebrates from Costa Rica to 325, represented by 89 species of digeneans, 23 of monogeneans, 63 of cestodes, 13 of acanthocephalans, and 137 of nematodes. In total, 133 species of vertebrates have been studied for helminths in Costa Rica (31 species of fishes, 7 amphibians, 18 reptiles, 40 birds, and 37 mammals). Currently, 67 species (20.6%) have been recorded as new species from Costa Rica and most of them are endemic to particular regions. The Coleccion de Helmintos de Costa Rica, housed at the Universidad de Costa Rica (UCR), San Jose, is the depositary of only 23% of the species recorded so far; however this situation is changing and people recognizes.

Key Words: Helminths, Costa Rica, Biodiversity, Biological inventories, Parasites, Vertebrates.

**********

The checklist of helminth parasites of vertebrates in Costa Rica, published recently (Rodriguez-Ortiz et al. 2004), updated all the available information about helminth parasites of vertebrates in Costa Rica along the past 50 years. Notwithstanding, the inventory of all eukaryotic parasites of the species of vertebrates living within the Area de Conservacion Guanacaste, Costa Rica, started in 1996 by Daniel R. Brooks and co-workers, has produced a great dealt of information in the last two years. For this reason, we present this addendum, in order to compile all this information and some other available records, all of them will be available electronically in 2004 at www.chcr.ucr.ac.cr.

MATERIALS AND METHODS

Refer to Rodriguez-Ortiz et al. (2004).

RESULTS

This addendum to the checklist contains records of 23 species included in 17 genera of helminths (9 digeneans, 1 acanthocephalan and 13 nematodes). 14 of them represent new species and 4 new genera. Helminths were reported in 25 species of vertebrates not previously studied in Costa Rica. Likewise, we add some taxonomic remarks made in recent publications on 5 species included in the original checklist. Next, we present the information for each species of helminth.

Aerial sacs, Jacana spinosa (B), Aranjuez, Puntarenas (Brenes-Madrigal and Arroyo-Sancho 1962). Specimens: CHCR.

Notes: this species was originally described as Cyclocoelum facioi Brenes-Madrigal and Arroyo-Sancho, 1962, included in the genus Haematotrephus Stossich, 1902 by Yamaguti (1971) and finally transferred to Uvitellina Witenberg, 1923 by Zamparo et al. (2003d).

DISCUSSION

After June, 2002, when we finished the compilation of the original "Checklist of the helminth parasites of vertebrates in Costa Rica" (Rodriguez-Ortiz et al. 2004), 14 papers have been published with new records on the helminth fauna of Costa Rican vertebrates (particularly in the Area de Conservacion de Guanacaste). In these studies, 23 additional species of helminths parasitizing 25 species of vertebrates have been described. About 76% of these new material was deposited in the CHCR. This fact establish a new era for the Coleccion de Helmintos de Costa Rica, since this collection will become a primary repository for parasite biodiversity in the country. To summarize, up to date 325 helminth species have been described in vertebrates from Costa Rica, represented by 89 species of digeneans, 23 of monogeneans, 63 of cestodes, 13 of acanthocephalans, and 137 of nematodes. We encourage people describing helminth parasites of this country to send specimens to be deposited and saved in this re-emerged collection.

RESUMEN

En este trabajo presentamos una addenda al "Listado de helmintos parasitos de vertebrados de Costa Rica". Esta addenda actualiza la informacion disponible acerca de este grupo de parasitos en dicho pais, cuyo estudio recientemente ha tomado un nuevo impulso. En este trabajo, se adicionan 33 registros, representando 23 especies. Lo anterior eleva el numero de especies de helmintos parasitos de vertebrados de Costa Rica registrado hasta ahora a 325:89 especies de digeneos. 23 de monogeneos, 63 de cestodos, 13 de acantocefalos, y 137 de nematodos. En total, 133 especies de vertebrados han sido estudiadas en busca de helmintos en Costa Rica (31 especies de peces, 7 de anfibios, 18 de reptiles, 40 de aves, y 37 de mamiferos). Hasta la fecha, 67 especies (20.6 %) fueron descritas como nuevas en Costa Rica y muchas de ellas son endemicas a una region particular. La Coleccion de Helmintos de Costa Rica, localizada en la Universidad de Costa Rica (UCR) en San Jose, resguarda material de unicamente el 23% de las especies registradas para el pais, pero afortunadamente esto esta cambiando actualmente.
