Cala, G. Galvis & S. Galvis leg., 8-13.VII.2017, 1 ♂ (ICN-Ar-10934) . Paratypes: same data as the holotype, 1 ♀ (ICN-Ar-12318), 1 ♀ (ICN-Ar-12319) .

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

Diagnosis. Males of Tenedos choco sp. n., can be recognized by their large, bifid retrolateral tibial apophysis (RTA), very large posterior branch (pRTA), curved towards dorsal side, apically bifid; thin, apically squared anterior branch (aRTA); large, bifid median apophysis (MA), short anterior branch (aMA); flattened, rounded posterior branch (pMA); very long embolus (E), forming arc at prolateral side; robust, very wide ventral tibial apophysis (VTA) ( Figs 29A–D ; 30A–B ). Females are characterized by thin lateral borders (LB), posteriorly positioned; very long seminal receptacles, describing C-shaped; longer than wide medial field plate, straight at basal edge ( Figs 29E–F ; 30C–D ).
