Martínez leg., 22-24.II.2004 , 1 ♀ (IAvH-I-666) . Etymology. The specific name is a noun in apposition taken from the type locality. Diagnosis. Males of Tenedos tatama sp. n. , resemble those of T. santarosa sp. n. , and T. eberhardi sp. n. , by shape and bifid retrolateral tibial apophysis (RTA); large median apophysis (MA) ( Figs 64A–D ; 65A–B ; 67A–D ; 68A–B ; 70A–D ; 71A–B ), but are distinguished by thinner posterior branch of the retrolateral tibial apophysis (pRTA) with thin posterior tip; large median apophysis, anteriorly concave ( Figs 70A–D ; 71A–B ). Females are similar those of Tenedos santarosa sp. n. , and T. eberhardi sp. n. by can be distinguished by very large, rounded median field plate (MFP); thin seminal receptacles (SR), slightly curved towards median septum ( Figs 64E–F ; 65C–D ; 67E–F ; 68C–D ; 70E–F ; 71C–D ).
