Small to medium-sized test checklists for cross-mapping 1. Droseraceae (sundew plants, Alastair Culham's GSD, so useful for expert opinion!) (a) 182 species with 158 synonyms and 52 infra-specific taxa with 179 synonyms in Droseraceae Database in AC 2009: see http://www.catalogueoflife.org/annual-checklist/2009/show_database_details.php?database_name=Droseraceae%20Database (b) which replaced the Droseraceae part of ITIS (16 species in AC2008) (c) 72 entries (not all are species) in NCBI Taxonomy 2. Solanaceae (or Solanum only) (a) 1,337 species (including 1,082 species of Solanum from the Solanaceae Source with 2,101 synonyms and 19 infra-specific taxa with 1,476 synonyms), the rest from ITIS in AC 2009 (b) which replaced 371 species in AC 2008, probably all from ITIS, including 135 Solanum spp. (c) 1,592 entries for Solanaceae and 631 for Solanum (not all are species) in NCBI Taxonomy 3. Gracillariidae (a family of moths with few synonyms and probably many changes) (a) 1,841 species (and 7 infra-specific taxa) and 411 synonyms in AC 2008: see http://www.catalogueoflife.org/annual-checklist/2008/show_database_details.php?database_name=World+Gracillariidae) (b) which replaced the Gracillariidae part of LepIndex (including 2,031 "provisional" species in AC 2007: see http://www.catalogueoflife.org/annual-checklist/2007/show_database_details.php?database_name=LepIndex) (c) 352 entries (not all are species) in NCBI Taxonomy 4. Phasmida (stick insects, with many synonyms in one checklist from David Eades (likely to be helpful for expert opinion!), the other checklist is very small (a) 2,821 species (and 93 infra-specific taxa) and 3,190 synonyms in AC 2008: see http://www.catalogueoflife.org/annual-checklist/2008/show_database_details.php?database_name=PSF) (b) which replaced the Phasmida part of ITIS (including 49 species in AC 2007: see http://www.catalogueoflife.org/annual-checklist/2007/show_database_details.php?database_name=ITIS) (c) 429 entries (as "Phasmatodea"; not all are species) in NCBI Taxonomy
