Type material. Holotype: COLOMBIA. Norte de Santander: Vereda El Diamante, Parque Nacional Natural Tamá, Sitio Inspección Santa Maria Alto de Herrera , mixed forest fragment, Pitfall trap, 1250m [7°06′N, 72°13′W], E. González leg., 29.IX.1999, 1 ♂ (IAvH-I-577) . Paratypes: same data as the holotype, 4 ♀ (ICN-Ar-12316), 1 ♀ (ICN-Ar-8006) .

Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Males of Tenedos tama sp. n., resemble those of T. dankittipakuli sp. n., T. humboldti sp. n., T. griswoldi sp. n., and T. piedecuesta sp. n., by bifid retrolateral tibial apophysis (RTA) with reduced anterior branch (aRTA); the shape of the median apophysis; presence of basal retrolateral tibial apophysis (bRTA) ( Figs 77A–D ; 78A–B ; 80A–D ; 82A–D ; 83A–B ; 85A–D ; 86A–B ; 88A–D ; 89A–B ; 91A–D ; 92A–B ), but are distinguished by narrow base of embolus (EB), retrolateral tibial apophysis (RTA) with thinner posterior branch (pRTA), shorter basal retrolateral tibial apophysis (bRTA), thinner posterior branch of the median apophysis (pMA), anterior branch (aMA) with rounded anterior edge ( Figs 85A–D ; 86A–B ). Females are similar to those of Tenedos dankittipakuli sp. n. and T. griswoldi sp. n. by the shape and disposition of seminal receptacles (SR); longer than wide median field plate (MFP) ( Figs 77E–F ; 78C–D ; 80E–F ; 82E–F ; 83C–D ; 85E–F ; 86C–D ), but are distinguished from mentioned species by oval median field plate and very wide at base seminal receptacles ( Figs 85E–F ; 86C–D ).
