This dataset provides information on specimens of harvestmen (Arthropoda, Arachnida, Opiliones) collected in French Guiana. Field collections have been initiated in 2012 within the framework of the CEnter for the Study of Biodiversity in Amazonia (CEBA: www.labex-ceba.fr/en/). This dataset is a work in progress. Occurrences are recorded in an online database stored at the EDB laboratory after each collecting trip and the dataset is updated on a monthly basis. Voucher specimens and associated DNA are also stored at the EDB laboratory until deposition in natural history Museums. The latest version of the dataset is publicly and freely accessible through our Integrated Publication Toolkit at http://130.120.204.55:8080/ipt/resource.do?r=harvestmen_of_french_guiana or through the Global Biodiversity Information Facility data portal at http://www.gbif.org/dataset/3c9e2297-bf20-4827-928e-7c7eefd9432c.Purpose
French Guiana is a French overseas department covered at 97% by primary forest (Gond et al. 2011). As such, it represents the only Outermost Region of Europe covering a large fraction of mainland in tropical South America. The territory is part of the Guianan moist forests ecoregion and has strong biogeographic affinities with the rest of the Amazonia bioregion (Olson et al. 2001). The biological diversity of French Guiana is now one of the best known in South America, yet some gaps in knowledge still exist, especially in arthropods. With more than 6500 species, harvestmen (Opiliones) is the third most diverse order of arachnid after Acari and Araneae (Kury 2013). They occur in superficial soil layers, leaf litter, under bark, and on vegetation from ground to canopy (Pinto-da-Rocha and Bonaldo 2006). The maximum richness of harvestmen species is found in the Neotropical region, however, diversity patterns within this region are still poorly known, both on regional and local scales. Because of their relatively high abundance and diversity in the Neotropical forests, they are useful candidates for studying community ecology (e.g. Proud et al. 2012), phylogeography, and biogeography (e.g. Sharma and Giribet 2012). By providing a database on harvestmen of French Guiana, regularly updated and publicly available, our goal is to provide a fast and efficient tool for sharing and tracking information on collected specimens. This database will be used for disseminating biodiversity information related to ongoing work on ecology and evolution of harvestmen in French Guiana. We also aim to promote best practices for recording and sharing biodiversity data within our research community. We believe this will make a valuable contribution to the global effort of sharing harvestmen database information (e.g. Merino-Sáinz et al. 2013).Sampling Description
Study Extent
Study sites were located throughout French Guiana.Sampling
The following techniques were used, however not all techniques were used on every collecting site and sampling design might not be similar among these sites. Pitfall traps: 20 plastic cups with 70% ethanol were distributed within a 0.5 hectare plot and exposed for 72 hours. Winkler: all the litter and superficial soil layer from 1 m2 was concentrated with the aid of a hand-sieve and sorted using a winkler apparatus during 2 days. Litter manual sorting: all the litter and superficial soil layer from 1 m2 was concentrated with the aid of a hand-sieve and sorted by hand using a plastic square plate. Beating: vegetation above knee-level was sampled using a 1 m2 beating sheet. Sweeping: vegetation below knee-level was sampled using a sweep net. Manual nocturnal ground search: samples are collected during the night on the ground or at the base of trunks. Manual search in and under the dead wood. Samples are collected by searching in and under the dead wood pieces or the dead trunks on the ground.Quality Control
GPS coordinates were obtained using a GPSmap 60CSx device or similar. Such devices report coordinates accuracy using the CEP50 (Circular Error Probability), meaning that there is only 50% probability that a reported position would be within a distance of X meters to the real position. Considering other sources of GPS errors (such as ionosphere delay and signal multi path) we estimate the accuracy of the coordinates to be around 30 meters at a 95% confidence level. Initial specimens identifications to the family level (for all families) and genus level (for Agoristenidae, Stygnidae and Gonyleptidae) have been checked by Ricardo Pinto-da-Rocha. Validity of the taxonomic names used was checked against the Encyclopedia of Life (http://www.eol.org) and the GBIF backbone taxonomy (http://www.gbif.org/dataset/d7dddbf4-2cf0-4f39-9b2a-bb099caae36c). Future validity checks could use the "World Checklist of Opiliones species", once it is published in its entirety (Kury et al. 2014).Method steps
- After collection, samples are sorted and placed in individual tubes containing 95% ethanol with a unique identifier until further processing in the laboratory. Codes are based on locality, collection date, collection method followed by a unique number as in GF140308HC001-07 which indicates that the specimen was collected in French Guiana (GF) on 2014-03-08 (yyyy-mm-dd), and hand collected (HC). Collection method codes include sweep net (SN, SND or SNN), beating (BND or BNN), pitfall (PT), winkler (WK, WKD or WKN). When specimen collection was part of a larger field expedition, we kept the original codes that might not follow this rule (as in SL13-1208-OP01 collected in Saül).
- Collecting information for each specimen is databased in an online Voseq database (Peña and Malm 2012) hosted by the EDB laboratory.
- Specimens are photographed using an Olympus DP20 mounted on a Leica MZ16 binocular and pictures are stored in the database.
- For each specimen, 1 or 2 legs are kept in a separate vial and stored at -20°C for further molecular investigation.
- Specimens are initially curated at the EDB laboratory by J. Murienne and can be deposited in museums for further taxonomic study. For example, specimens of Sclerosomatidae have been sent as gift to the Museum of Comparative Zoology (MCZ) at Harvard University, Cambridge USA, to be investigated by Ana Lucia Tourinho. The current localisation of the specimens (either at EDB or in museums) can be found under the "disposition" field.
Additional info
The authors would like to thank the organizers of logistical support for the field missions (C. Baraloto, A. Fouquet, Parc Amazonien de Guyane, CNRS Guyane), all the contributors that helped collecting samples in the field during the CEBA missions (V. Vedel, A. Cerdan, J. Orivel and J. Donald) as well as those who kindly provided us specimens (A. Fouquet, C. Duplais, J.-P. Vacher, P.O. Cochard, M. Berroneau, M. Berroneau, L. Barthe, J. Pétillon and A. Lorenzini) and helped in species identifications (G. Giribet, A. Kury, A. Perez, R. Pinto-da-Rocha, A.L. Tourinho). We would also like to thank the GBIF France (M.-E. Lecoq and S. Pamerlon) for helping us with setting up the IPT. The EDB lab is supported by "Investissement d'Avenir" grants managed by Agence Nationale de la Recherche (CEBA: ANR-10-LABX-25-01; TULIP: ANR-10-LABX-41, ANR-11-IDEX-0002-02). Finally we greatly thank A. Kury, D. Proud and C. Richart for improving the manuscript.Taxonomic Coverages
This database is devoted to all harvestmen species inhabiting French Guiana. Little is known about the taxonomy of the group in French Guiana but some information are available in Kury (2003) for Laniatores and Benavides and Giribet (2013) for Cyphophthalmi. Identifications to the family level were conducted based on Kury and Pinto-da-Rocha (2002) and Pinto-da-Rocha et al. (2007). Three families are here reported for the first time in French Guiana, namely Agoristenidae, Fissiphalliidae and Icaleptidae. Identifications of Stygnidae to the species level were conducted based on Pinto-da-Rocha (1997).

Geographic Coverages
The sampling area is delimited by the current administrative boundaries of the French Guiana territory. To the East, the Oyapock River delimits the frontier with Brazil. To the West, the Maroni River delimits the frontier with Surinam. This is an important detail as the delimitation of the territory has not been constant throughout history and a large portion of northern Brazil was disputed between France and Brazil during the 19th century. Several species described or reported from French Guiana during the 19th century and early 20th century (see Kury 2003) are actually located in Brazil. Even though French Guiana is an overseas department and region of France, all occurrences have been recorded under the "French Guiana" country to comply with the ISO 3166-1 standard.
