Montes leg., 24-26.VII.2004 , 1 ♂ (IAvH-I-2973). Etymology. The epithet is a noun in apposition honoring to the Marquetones, indigenous people who lived in the Caldas department . Diagnosis. Males of Tenedos marquetones sp. n. , resemble those of T. pensilvania sp. n. , by wide retrolateral tibial apophysis (RTA); large median apophysis (MA); basal tegular membrane (BTM) flattened at proximal side ( Figs 73C–F ; 74C–F ; 75A–B, D–E ), but are distinguished by bifid median apophysis with squared-shaped anterior branch, short posterior branch; thinner apically tapered retrolateral tibial apophysis with apical denticles ( Figs 73C–F ; 75B–E ).
