Etymology. The specific epithet is a patronymic in honor of the eminent arachnologist Charles Griswold by his contributions to the taxonomy and systematic of spiders.
Diagnosis. Males of Tenedos griswoldi sp. n., resemble those of T. dankittipakuli sp. n., T. humboldti sp. n., T. tama sp. n., and T. piedecuesta sp. n., by presence of basal retrolateral tibial apophysis (bRTA), the shape of median apophysis (MA); bifid retrolateral tibial apophysis (RTA) (Figs 77A–D; 78A–B; 80A–D; 82A–D; 83A–B; 85A–D; 86A–B; 88A–D; 89A–B; 91A–D; 92A–B), but can be distinguished by long, hook-shaped basal retrolateral tibial apophysis (bRTA), sharp at apex;very short, apically bifid retrolateral tibial apophysis (RTA) with wide anterior branch (aRTA); large median apophysis with squared anterior branch, very thin posterior branch (Figs 82A–D; 83A–B). Females are similar to those of Tenedos dankittipakuli sp. n. and T. tama sp. n., by short lateral borders (LB), posteriorly positioned; large median field plate (MFP); very wide seminal receptacles (SR), slightly towards median septum of epigyne (Figs 77E–F; 78C–D; 80E–F; 82E–F; 83C–D; 85E–F; 86C–D), can be distinguished by wider than long median field plate; longer, wavy seminal receptacles (Figs 82E–F; 83C–D).
Description. Male (Holotype, ICN-Ar-8023). Coloration (Fig. 81A–B): carapace brown-reddish. Chelicerae with the paturon brown and yellowish on apical region, fangs brown-reddish. Endites light brown, yellow on anterior region. Labium and sternum light brown. Legs: Coxae I–IV light yellow. Femora I–IV yellow, lighter on basal region. Patella I yellow, II–IV light brown. Tibiae, metatarsi, and tarsi I–II yellow, III–IV light brown. Abdomen: dorsally dark gray with six white guanine spots organized as follows: two rounded and large spots, anteromedially positioned; two oval spots larger than previous ones, medially positioned; two irregular and wider spots with an anterior notch, medially positioned; two large and traversal spots, fused medially and posteriorly positioned. Laterally dark gray with two thin and tripartite stripes along its full extension. Ventrally dark gray, with two large and wide stripes on lateral sides, and several adjacent spots. Spinnerets light yellow. Measurements: total length 5.29, carapace length 2.68, width 1.84, height 1.11. Clypeus height 0.71.
