Diagnosis. Males of Tenedos humboldti sp. n., resemble T. dankittipakuli sp. n., T. griswoldi sp. n., T. tama sp. n., and T. piedecuesta sp. n., by wide retrolateral tibial apophysis (RTA); the shape of the median apophysis (MA) with laminar anterior branch (aMA); the presence of a basal retrolateral tibial apophysis (bRTA) (Figs 77A–D; 78A–B; 80A–D; 82A–D; 83A–B; 85A–D; 86A–B; 88A–D; 89A–B; 91A–D; 92A–B), but are distinguished by more complex abdominal spots patterns; anterior branch of retrolateral tibial apophysis (aRTA) very thin and longer than in latter species; longer and tapered posterior branch (pRTA); median apophysis with short projection on anterior branch (Figs 88A–D; 89A–B). Females are recognized from mentioned species by wider seminal receptacles (SR); wider than long median field plate (MFP) with rounded basal edge (Figs 88E–F; 89C–D).
Description. Male (Holotype, IAvH-I-613). Coloration (Fig. 87A–B): carapace uniformly brown-reddish. Chelicerae with paturon brown, fangs brown-reddish. Endites brown, white on anterior region. Labium and sternum brown. Legs: Coxae I–IV light brown. Femora I–IV pale yellow on basal side and light brown the rest of its extension. Patellae I–IV brown. Tibiae I–IV pale brown. Metatarsi-tarsi I–IV light brown. Abdomen: dorsally dark gray with ten white guanine spots organized as follows: eight irregular spots, decreasing in size towards posterior region, placed from the median to posteromedial region, the latter spots are liked by a very thin bands; two transversal and large bands, posteriorly positioned. Laterally dark gray with two oblique spots, posteriorly positioned. Ventrally dark gray with small spots on lateral sides. Spinnerets light brown. Measurements: total length 5.59, carapace length 2.81, width 1.92, height 1.15. Clypeus height 0.55.

Palp: retrolateral process of cymbium (RPC) long, widening towards base; tegulum (T) rounded; subtegulum (St) large, longer than wide in ventral view; conductor (C) large with short, thin sclerotized region on distal side; appendix (ApC) short, apically sharp; embolus (E) long, laminar at base with short projection, filiform towards apex; base of embolus (EB) approximately as long as two times as basal tegular membrane; basal tegular membrane (BTM) very thin, lanceolate, originated basally on tegulum; spermatic ducts (SD) S-shaped, long, wide with anterior fold more opened, wider than posterior; ventral tibial apophysis (VTA) large, anteriorly projected; median apophysis (MA) large, bifid with small projection on anterior branch (aMA), posterior branch (pMA) very short; retrolateral tibial apophysis (RTA) large, bifid with very thin, laminar anterior branch (aRTA), displaced to dorsal region, curved and forming a concavity posterior branch (pRTA); basal retrolateral tibial apophysis (bRTA) short, wide, forming a concavity (Figs 88A–D; 89A–B).
Female (Paratype, IAvH-I-611). Coloration and abdominal pattern of spots as male, except legs uniformly brown (Fig. 87C–D).
