Etymology. The specific epithet is given in honor of Luz Marina Cuervo Sepulveda, mother of the third author for her support and love.

Diagnosis. Males of Tenedos luzmarinae sp. n. resemble those of T. peckorum Jocqué & Baert, 2002 , T. quipile sp. n., T. mesa sp. n., and T. henrardi sp. n., by having complex retrolateral tibial apophysis (RTA); large median apophysis (MA) with quadrangular-shaped anterior branch and tubular posterior one (see Jocqué & Baert, 2002: 111, fig. 29A–B; figs 34C–F; 36A–D; 37A–B; 38C–F; 40A–B; 42A–D; 43A–B; 44A–F; 46A–D; 47A–B; 55A–D; 56A–B), but can be distinguished by longer, thinner, apically curved anterior branch of median apophysis (aMA); retrolateral tibial apophysis (RTA) with bifid and wide anterior branch (aRTA), long posterior branch (pRTA), apically rounded ( Figs 55A–D ; 56A–B ). Females are similar those of Tenedos barronus Jocqué & Baert, 2002 , T. hoeferi Jocqué & Baert, 2002 , and T. quadrangulatus Jocqué & Baert, 2002 , by long seminal receptacles (SR) curved towards median septum of epigyne (see Jocqué & Baert, 2002: 87, 100, 116, figs 10C–D, 18D–E, 33A–B; figs 12E–F; 13C–D; 55E–F; 56C–D), but are characterized by elongated atrium (A) and tongue-shaped median field plate (MFP) ( Figs 55E–F ; 56C–D ).

Palp: retrolateral process of cymbium (RPC) thin, wide at base; tegulum (T) sub-rounded, almost as wide as long; subtegulum (St) almost as long as wide in ventral view, with rounded external edge; conductor (C) moderately developed, with long, strongly sclerotized region on distal side; appendix (ApC) long, apically sharp; embolus (E) long, wide at base, filiform towards apex; base of embolus (EB) approximately as wide as basal tegular membrane; basal tegular membrane (BTM) very short and flattened ending as a short tip; spermatic ducts (SD) both folds full open; ventral tibial apophysis (VTA) large, tubular, curved; median apophysis (MA) bifid, with rectangular anterior branch (aMA), posterior branch (pMA) very short, tubular; retrolateral tibial apophysis (RTA) large, complex with bifid anterior branch (aRTA) ( Figs 55A–D ; 56A–B ).
