The total number of collections is shown, including the number georeferenced (thus included in the calculations using ConR). " Unique occurrences " represent those with differing coordinates, whereby for poorly collected species, numbers of collections that could not be precisely georeferenced but nevertheless represent additional occurrences are indicated; " locations " refers to the IUCN definition as " a geographically or ecologically distinct area in which a single threat can rapidly affect all individuals of the taxon present "; and " subpopulations " are " geographically or otherwise distinct groups in the population between which there is little demographic or genetic exchange (IUCN 2012). EOO = extent of occurrence, whereby the criteria contributing to endangered status are CR <100 km 2, EN <5,000 km 2 and VU <20,000 km 2; AOO = area of occupancy, whereby the criteria are CR <10 km 2, EN <500 km 2 and VU <2,000 km 2. We estimated EOO and AOO using ConR, also indicating for (potentially) threatened species where the values would be higher taking non-georeferenced specimens into account. Known occurrences (or not) in protected areas (national parks or reserves with protected status according to the IUCN; https: // protectedplanet. net / accessed 04.09.2018) are documented and an overall threat category with IUCN code is presented which takes into account each of these factors (as discussed individually in each species treatment)." httpUri="http://table.plazi.org/id/45F44CBB3BA4F892B1D1B4BC42D3B1F1" pageId="0" pageNumber="1" tableUuid="45F44CBB3BA4F892B1D1B4BC42D3B1F1">1</tableCitation>
