Generous financial support from the Norwegian Research Council and the Nansen Fund has been vital to the many expeditions where samples have been collected. Financial help from Decanato de Investigación y Desarrollo of Universidad Simón Bolívar through projects DID-CB-009-98 and DI-CB-012-01, and FONACIT S1–2001000663 also is acknowledged. We deeply appreciate Bruno Manara's corrections of the Latin diagnosis. We also thank Héctor Urbina for help with the final editorial work.
