Etymology. The epithet is a noun in apposition honoring to Ticunas (Tikunas), indigenous people who live in Amazonian region.

Diagnosis. Males of Tenedos ticuna sp. n., resemble those of T. hoeferi Jocqué & Baert, 2002 , by having a developed conductor (C) curved at prolateral side (see Jocqué & Baert, 2002: 100, fig. 18B–C; figs 22A–D; 23A–B), but can be recognized by extremely curved conductor (C) at prolateral region; very short and apically pointed retrolateral tibial apophysis (RTA); bifid median apophysis (MA), very wide, flattened, procurved anterior branch (aMA) ( Figs 22A–D ; 23A–B ). Females are similar those of T. hoeferi Jocqué & Baert, 2002 and T. quadrangulatus Jocqué & Baert, 2002 , by wide seminal receptacles (SR), curved towards median septum of epigyne; knob-shaped median field plate (MFP) (see Jocqué & Baert, 2002: 100, 116, fig. 18D–E, 33A–B; figs 22E–F; 23C–D), but can be distinguished by wider seminal receptacles, larger, rounded median field plate; rounded spermathecae (S), close to copulatory ducts (CD) ( Figs 22E–F ; 23C–D ).

Description. Male (Holotype, MPUJ_ENT 0062000). Coloration ( Fig. 21A–B ): carapace brown with dark patches around ocular region. Chelicerae with paturon light brown, fangs brown-reddish. Endites, labium, and sternum dark brown. Legs: Coxae I–IV yellow, darker on distal side. Femora, patellae, tibiae, and metatarsi I–IV dark brown, femora apically dark brown. Tarsi I–IV yellow. Abdomen: dorsally dark gray with three white guanine spots organized as follows: two large and rounded spots, medially positioned; a transversal and large spot, posteriorly positioned. Laterally dark gray without spots. Ventrally dark gray without spots. Spinnerets light yellow. Measurements: total length 4.63, carapace length 2.32, width 1.46, height 1.01. Clypeus height 0.48.

Abdomen length 2.24. Legs spines pattern (only the differences from the general pattern): III—femur r0-0-1d; IV—femur p0-0-1d. Palp: retrolateral process of cymbium (RPC) long, wide, widening slightly towards base; tegulum (T) large, rounded, almost as long as wide; subtegulum (St) longer than wide; conductor (C) very developed, wide, strongly curved at prolateral side, anteriorly projected, and with short and wide sclerotized region on distal side; appendix (ApC) long, sharp; embolus (E) long, filiform towards apex; base of embolus (EB) approximately three times as long as basal tegular membrane; basal tegular membrane (BTM) originated basally on tegulum, ending as very short appendix; spermatic ducts (SD) S-shaped, anterior fold wider than posterior; ventral tibial apophysis (VTA) very small, quadrangular; median apophysis (MA) large, bifid, laminar, both branch almost of equal length; retrolateral tibial apophysis (RTA) shorter than palpal tibia, acuminated ( Figs 22A–D ; 23A–B ).

Female (IAvH-I-3762). Coloration and abdominal pattern of spots as male ( Fig. 21C–D ). Measurements: total length 5.70, carapace length 2.68, width 1.63, height 1.14. Clypeus height 0.52.

Legs spines pattern (only the differences from the general pattern): I—tibia v1r-1r-2, metatarsus v1r-0-2; II—tibia v=I, p0-1d-1d, metatarsus v1r-1r-2; III—tibia v1p-1p-2, metatarsus 2-1p-2p; IV—tibia V=III (1p-1p-1p-2), metatarsus v2-2-2. Epigyne: lateral borders (LB) short, restricted to posterior region, forming sub-rounded atrium (A); median field plate (MFP) large, rounded-shaped; copulatory ducts (CD) very short, thin; seminal receptacles (SR) very long, wide, curved towards median septum; spermathecae (S) large, rounded, posteriorly positioned; fertilization ducts (FD) almost as long as spermathecae length ( Figs 22E–F ; 23C–D ).
