Key to species of Columbianum   from Amazonia

Note that it would be preferable for the key to include all species of Columbianum   , but as some of the published descriptions are poor this would require more comprehensive work which is outside the scope of this study.

1 Large, dark and robust species, body width at least 1.8 mm ................................... C. major   sp. nov. – Smaller species, body width less than 1.0 mm ................................................................................. 2

2 With strongly domed head and very narrow rostrum; head and metazonites with tubercles but not appearing rugose; prozonites wider than metazonites; medium sized (body width 0.8–1.2 mm) ...... ........................................................................................................................................ C. nahvalr   sp. nov.

– With clear distinction between head and rostrum, but head not strongly domed; very rugose, with abundant tubercles on head and metazonite; prozonites the same width as metazonites or narrower; smaller size (body with 0.59–0.98 mm) .................................................................... C. adisi   sp. nov.
