Etymology. 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). Females are characterized by shape of median field plate (MFP), quadrangular, wider than long; short seminal receptacles (SR) (Figs 42E–F; 43C–D).
Description. Male (Holotype, ICN-Ar-12339). Coloration (Fig. 41A–B): carapace dark brown. Chelicerae with paturon brown, brown-reddish fangs. Endites, labium and sternum brown. Legs: Coxae I–IV white. Femora I–IV yellow on basal region, distally dark orange. Patellae-tibiae I–IV dark orange. Metatarsi-tarsi I–IV brown. Abdomen: dorsally dark gray with seven white guanine spots organized as follows: two rounded spots, anteriorly positioned; two oval spots larger than previous ones, anteromedially positioned; two rounded and larger spots with an anterior notch, medially positioned; a large and traversal spot, posteriorly positioned. Laterally dark gray with a wide and oblique stripe, decreasing in size to the posterior side. Ventrally dark gray, with two large and wide stripes on lateral sides, and several adjacent spots. Spinnerets dark gray. Measurements: total length 5.91, carapace length 3.06, width 1.93, height 1.23. Clypeus height 0.55. Eye diameters and interdistances: AME 0.04, ALE 0.10, PME 0.12, PLE 0.14; AME–AME 0.19, AME–ALE 0.24, AME–PME 0.27, PME–PME 0.31, PME–PLE 0.41, ALE–PLE 0.25. Chelicerae 1.12 length. Sternum length 1.17, width 1.09.

Abdomen length 2.81. Legs spines pattern (only the differences from the general pattern): III—femur d0-0-1p, p0. 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.
