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 ).
