    Abstract

    We describe here fi ve new species of Astroblepus for the Santander, Nariño and Putumayo Departments – Colombia. These fi sh differentiate from other known as Astroblepus due to its adipose fi n, which in A. bellezaensis and A. mojicai have a completely developed adipose membrane, without spine traces. A. ardiladuartei has an obsolete adipose fi n; a. nettoferreirai has a denticulated spine within the adipose fi n; A. putumayoensis has a movable spine connected to the caudal peduncle with a membrane in adipose fi n. A. belezaensis has 6 branched soft radii associated to third radial; A. mojicai has 7 soft radii; and the same happens in A. ardiladuartei and A. putumayoensis; A nettoferreirai has 8 soft radii. A bellezaensis has the premaxillary with 1 – 3 bicuspid teeth and 8 – 12 conic teeth in external row; A. mojicai has 2-5 bicuspid teeth and 5-11 conic teeth in external row; A. ardiladuartei has 0 - 1 bicuspid teeth and 6 – 10 conic teeth in external row; A. nettoferrreirrai has 1 - 2 bicuspid teeth and 6 – 11 conic teeth in external row; A. putumayoensis has 1 - 5 bicuspid teeth and 4 – 6 conic teeth in external row. A. putumayoensis has 21 – 22 free vertebrae; A. ardiladuartei has 24 vertebrae, A. bellezaensis and A. mojicai have 26 vertebrae, and 27 in A. nettoferrreirai.
