Etymology.
The specific name is a noun in apposition taken from the
type
locality.
Diagnosis.
Males of
Tenedos tatama
sp. n.
, resemble those of
T. santarosa
sp. n.
, and
T. eberhardi
sp. n.
, by shape and bifid retrolateral tibial apophysis (RTA); large median apophysis (MA) (
Figs 64A–D
;
65A–B
;
67A–D
;
68A–B
;
70A–D
;
71A–B
), but are distinguished by thinner posterior branch of the retrolateral tibial apophysis (pRTA) with thin posterior tip; large median apophysis, anteriorly concave (
Figs 70A–D
;
71A–B
). Females are similar those of
Tenedos santarosa
sp. n.
, and
T. eberhardi
sp. n.
by can be distinguished by very large, rounded median field plate (MFP); thin seminal receptacles (SR), slightly curved towards median septum (

Description.
Male
(
Holotype
, IAvH-I-2965). Coloration (
Fig. 69A–B
): carapace uniformly dark brown. Chelicerae with paturon brown, fangs brown-reddish. Endites brown, white on anterior region. Labium and sternum light brown. Legs: Coxae I–IV light yellow. Femora I–IV with base brown, white on medial region and distally brown. Patellae dark brown. Tibia I pale yellow, II–IV brown with light patches. Metatarsi I–IV yellow with brown patches. Tarsi I–IV dark brown. Abdomen: dorsally dark gray only can distinguish six white guanine spots organized as follows: two elongated spots, anteriorly positioned; two oval spots smaller than previous ones, sub-medially positioned; two transversal and large spots, medially positioned. Laterally dark gray without spots. Ventrally dark gray with small spots on lateral sides and a long and wide central spot. Spinnerets light brown. Measurements: total length 5.40, carapace length 2.76, width 1.83, height 1.27. Clypeus height 0.57. Eye diameters and interdistances: AME 0.08, ALE 0.09, PME 0.11, PLE 0.13; AME–AME 0.20, AME–ALE 0.23, AME–PME 0.24, PME–PME 0.25, PME–PLE 0.33, ALE–PLE 0.24. Chelicerae 0.74 length. Sternum length 1.08, width 1.01. Legs: I—femur 1.80/ patella 0.66/ tibia 1.59/ metatarsus 1.39/ tarsus 1.09/ total 6.53; II—1.53/ 0.73/ 1.20/ 1.29/ 0.76/ 5.51; III—1.43/ 0.73/ 1.02/ 1.20/ 0.68/ 4.91; IV—1.81/ 0.72/ 1.48/ 1.86/ 0.93/ 6.80. Abdomen length 2.31. Legs spines pattern (only the differences from the general pattern): I-II—tibia v1r-1r-0, metatarsus v1r-1r-2; III—metatarsus v2-1p-2; IV—tibia v2-2-2. Palp: retrolateral process of the 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, filiform towards apex; base of embolus approximately as long as basal tegular membrane; basal tegular membrane (BTM) wide, originated basally on tegulum, reticulated, very short, apically rounded; spermatic ducts (SD) S-shaped, short, wide, with both folds full open; ventral tibial apophysis (VTA) large, anteriorly projected; median apophysis (MA) large, wide, strongly sclerotized with small posterior projection; retrolateral tibial apophysis (RTA) large, almost as long as palpal tibia, apically bifid, anterior branch (aRTA) very short, posterior (pRTA) thin (

Figs 70E–F
;
71C–D
).
Distribution.
Known from
Risaralda department
(
Fig. 107
).
Remark.
Female and male were matched by having the same abdomen spots patterns and the localities where these specimens are closely related.
