Drawing from “Cyprinodon” martae, conform the single specimen in Vienna. © by F. Vermeulen.

The time of waiting was over as the unstable political situation changed in so far that the journey became not necessarily to be fatal. And so I made me on my way. I planned a short trip of only one Week and one of my Colombian workers accompanied me to assist me in the field or if language would bring me in problems. Together we took the flight to Barranquilla and after that we took a bus to Santa Marta. From Santa Marta, we made several trips along the slopes of the Sierra Nevada. To the north was the province of La Guajira, a peninsula that is formed by the Northeast-passat, a moonlike dry landscape with low bushes and cactuses, scattered with temporary waters. South of Santa Marta, banana- and palm plantations as far as the eye can see, from time to time interrupted by areas where cattle was grazing. In that region plenty of rain is falling. On many locations there are rivers that flow down from the Sierra Nevada usually very cold, fast flowing streams. Most of these riverbeds are filled with huge stones and gravel and surrounded by forests.
