The specific epithet is a patronymic in honor of the arachnologist Arnaud Henrard by his contributions to the taxonomy and systematic of the ant-eating spiders. Diagnosis. Males of Tenedos henrardi sp. n. , are similar those of T. peckorum Jocqué & Baert, 2002 , T. quipile sp. n. , and T. mesa sp. n. by having bifid median apophysis (MA) with squared anterior branch (aMA); complex retrolateral tibial apophysis (RTA) (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), but can be distinguished by large median apophysis, shorter, strongly recurved posterior branch (pMA); large retrolateral tibial apophysis with laminar posterior branch (pRTA), almost as long as anterior branch (aRTA), narrowing to apex ( Figs 42A–D ; 43A–B ; 44A–F ).

Palp: retrolateral process of cymbium (RPC) long, wide; tegulum (T) large, rounded, longer than wide, retrolateral excavation very accentuated; subtegulum (St) small, almost as long as wide; conductor (C) developed, wide; appendix (ApC) short, apically sharp; embolus (E) long, filiform towards apex; base of embolus approximately as long as two times as basal tegular membrane width; basal tegular membrane (BTM) originated basally on tegulum, proximally flattened, ending as very short and sharp appendix; spermatic ducts (SD) S-shaped, both folds thin, full open; ventral tibial apophysis (VTA) short, quadrangular-shaped in ventral view; median apophysis (MA) large, bifid, anterior branch (aMA) squared, posterior branch (pMA) tubular, recurved; retrolateral tibial apophysis (RTA) large, longer than palpal tibia, both branches overlapping each to other, posterior branch (pRTA) very wide, anterior branch (aRTA) laminar, thin ( Figs 42A–D ; 43A–B ; 44A–F ). Female ( Paratype , ICN-Ar-12340). Coloration and abdominal pattern of spots as male, carapace brown ( Fig. 41C–D ). Measurements: total length 7.41, carapace length 3.78, width 2.38, height 1.61.
