Abstract

A catalogue of type material of monogenoids deposited in the Helminthological Collection of the Oswaldo Cruz Institute, FIOCRUZ (CHIOC), between 1979 and 2016, is presented, given that the last list of types was produced in 1979. The monogenoid collection comprises type lots for 203 species, distributed across 14 families and 68 genera. Specific names are listed systematically, followed by type host, infection site, type locality, specimens with the collection numbers and references. The classification and the nomenclature of the species have been updated.

Introduction

Natural history collections provide important documentary evidence of biodiversity and the information that they contain is very useful. In the case of helminthological collections, the specimens acquired have been a source not only for knowledge of helminth biodiversity, but also for parasitological studies on taxonomy, systematics and identification of causes of zoonoses. The century-old , Rio de Janeiro, Brazil, contains helminths that form part of the fauna of Brazil and other countries, from a wide range of hosts that were caught in different biomes. The samples are holotypes, paratypes and representative specimens of (, and ), , and other non-helminth phyla, such as and . Recently, a large number of species of were deposited in the CHIOC, which reflects the increased number of taxonomists working on this group in Brazil.

History and composition of the collection

The CHIOC celebrated its centenary in 2013. Its history is intertwined with that of the , which began with the fieldwork of Gomes de Faria and his student Lauro Travassos (Faria and Travassos 1913). The Collection also received important contributions from other researchers at that time and, since then, it has increased in size through incorporation of private and institutional collections of the late nineteenth and early twentieth centuries (Noronha 2004, Noronha et al. 2004, 2009). Laboratory of Helminth Parasites of Vertebrates of the Oswaldo Cruz Institute Today, the CHIOC holds around 38.400 samples of helminth parasites from South America and other continents. It is the biggest collection in Latin America and it is among the largest collections at a worldwide reference level (Rego 1982, Knoff et al. 2010), not only because of the number of types, but also because of the number of representative specimens (vouchers) that it contains. The collection has been constantly expanding through the large numbers of deposits made by Brazilian and foreign researchers. Some samples of arthropods (mainly pentastomids) and annelids (parasitic leeches) have also been accepted for inclusion in the collection, thus expanding its original nature of focusing on helminthological parasites of vertebrates, and resulting in a diversified parasitological collection. All the material is organized according to the lots, which are numbered, recorded in an entry book, and digitized into a database. They are maintained in modern steel sliding closets and in a freezer that maintains some specimens and eggs of Sambon, 1907 () at -30 °C. Most of the information on the sample collections is available on the CHIOC web page (http://chioc.fiocruz.br/) and through the speciesLink network of the . Deposits and loans of specimens, permission for visits to examine samples in loco, PageBreakloans of books and reprints, mini-courses and lectures focusing on the history of the CHIOC, and professional capacitation courses are included among the facilities of this Collection. Environmental Information Reference Center The first and only catalogue of the type material held in the CHIOC was published by Rego et al. (1979). They recorded 719 types (only holotypes or type series) of helminths, including 408 of nematodes, 227 of trematodes ( and ), 52 of acanthocephalans, 28 of cestodes and four of pentastomids. Subsequent to this publication, the collection has grown substantially and the number of types has increased significantly as well. The purpose of this article is to inform the scientific community about the acquisitions of the CHIOC by publishing a catalogue of types deposited up to August 1, 2016. Because of the large number of types, we are starting with the species of . We have followed the articles 73–75 of the Code (ICZN 1999).

Material and methods

The specimens are stored in glass or plastic vials in 70% ethanol or as microscope slide preparations. All the material is available for consultation, but holotypes are not loaned. Unless otherwise stated, all type material is in good condition. The catalogue is arranged taxonomically as subclasses, families, genera and species, under the original spelling and combinations. Subclasses are arranged following phylogenetic order. Families, genera and species are arranged alphabetically. The information on each entry is presented in the following format: Original genus-species combination with author(s) and year of publication. Asterisk (*) denotes the type species of the genus. Type host: species, author(s) and principal taxonomic group in brackets. Infestation or infection site in the host. Type locality: country, province or state, department, specific locality and coordinates (if available). Primary type status: CHIOC catalogue number. The categories for the types used followed articles 73–75 of the Code (ICZN 1999). Remark sections are inserted when necessary and include additional information about host, locality or status of the types. References include publications in which the species was described and those that mention type specimens in the CHIOC. The valid names adopted for parasitized hosts follow the most recent bibliography. Fish names are present in accordance with Froese and Pauly (2016) and turtle names, in accordance with Fritz and Havaš (2007, 2013). Mention of the monogenoids and host species in this list does not imply that the authors of the present report agree with their validity or taxonomy. Some monogenoids species catalogued have been PageBreaksynonymized and the comments about their taxonomy are in the Remarks sections. The higher classification of follows Boeger and Kritsky (1993), and for families and genera follows specific references.

Results and discussion

This database and bibliographic survey presents the diversity of types in CHIOC, from Brazil and other countries in the world, covering more than 35 years of parasitological studies. This catalogue is the second list of type species held in PageBreakthis Collection. The only previous checklist recorded only 11 type species of monogenoids, without considering paratypes (Rego et al. 1979). Now, there is a total of approximately 1100 primary types of , represented by 203 species distributed across 14 families and 68 genera. is the most representative family, with 141 species, followed by , with 29. These numbers illustrate the importance of the parasitological collection of the CHIOC, which is among the most significant in Latin America, together with other collections in Mexico and Argentina (Lamothe-Argumedo et al. 2010, Tablado and Tricárico 2010, Lunaschi et al. 2012). It was observed that 93% of the type species of monogenoids catalogued in this Collection were parasites of bony fish. Only 12 species were parasites of cartilaginous fishes () and two monogenoids were parasites of turtles ( and ). All those samples were collected mainly in Brazil (95%), from all regions of this country. This situation could be a reflection of the large number of studies carried out on fish from Brazilian rivers and the Atlantic Ocean, and especially, of the increase in knowledge of monogenoids in Brazil that has been achieved since the late 1960s (Cohen et al. 2013).
