	abstract = {This paper analyzes the Coleoptera part of the first global checklist of insects from French Guiana, up to the end of 2013, published online in the French species database TAXREF (http://inpn.mnhn.fr). We describe the level of knowledge by family, the pace of description and compare it with other insect Orders. We also focus on characterizing the patterns in the taxonomical work currently concerning this beetles fauna.
Excluding erroneous or dubious records, 5 830 species of Coleoptera are reported in 1852 genera belonging to 71 families. Currently at least 28\% of the species are only known from French Guiana or from the Guiana shield region. Since Linn{\'e}, the average rate of description has been of 23 species per year, but it has been increasing recently, reaching 84 species on average these last five years. Based on a sample of recent taxonomic and faunistic articles covering 625 added species for French Guiana, 47\% came from new country records and 53\% from the description of new species. The rate of faunistic progress (new species or new records) is of about 150 species per year (84 new species + 66 new country records) during the last five years. More than 65\% of these faunal novelties came from non-professional entomologists and 73\% of the holotypes of new species were collected by amateur entomologists. A rough extrapolation of the potential number of species using two independent methods yields a likely estimate of 28 000 to 29 000 species (overall between 20 000 and 39 000). Therefore, between 70 and 80\% of the species remains to be recorded and, in a best-case scenario, at least 100 years would be needed to achieve a complete biotic survey. Although no family is exhaustively inventoried, the most popular ones are the best studied (Longhorns, Scarabs and Tiger beetles). The most in need of study are the largest families that have fewer taxonomists focusing on them (e.g. Curculionidae, Chrysomelidae and Staphylinidae) and the numerous small families which received no particular attention. These results and the fundamental role played by non-professional entomologists in collecting and describing species are discussed to explain why, unlike the general worldwide trend, there is no decline in beetles taxonomy concerning French Guiana.

	abstract = {This paper analyzes the first checklist of insects from French Guiana. Compiled by a group of 70 experts based on published records, it comprises about 15 100 valid species names belonging to 20 orders and 322 families. Currently, about 17\% of the species are only known from French Guiana or from the Guiana Shield region. Since Linn\&eacute;, the average rate of description has been 59 species per year, which has been increasing in the last 10 years. Based on a sample of recent taxonomic and faunistic papers covering 736 new species for French Guiana, 46\% of the species came from new country records, the rest from new species descriptions. The rate of faunistic progress (new species or new records) is about 180 species per year over the last five years. Sixty-five percent of these faunal records came from non-professional entomologists and 74\% of the holotypes of new species were collected by amateur entomologists. A rough extrapolation, using two different methods, provides a likely estimate of around 100 000 species, the most conservative estimate being 67 000 species and the highest 184 000. Therefore, an estimated 80\% of the species remain to be recorded and, in a best-case scenario, at least 270 years would be needed to complete the biotic inventory, at the current rate of species descriptions and distribution records. Although no order is exhaustively inventoried, the most in need of study are Diptera, Hymenoptera, Hemiptera and Trichoptera; and in absolute numbers, Coleoptera. These results and the fundamental role of non-professional entomologists in collecting and describing new species are discussed.
