Etymology. The specific epithet is a patronymic in honor of the arachnologist Arnaud Henrard by his contributions to the taxonomy and systematic of the ant-eating spiders.

Diagnosis. Males of Tenedos henrardi sp. n., are similar those of T. peckorum Jocqué & Baert, 2002 , T. quipile sp. n., and T. mesa sp. n. by having bifid median apophysis (MA) with squared anterior branch (aMA); complex retrolateral tibial apophysis (RTA) (see Jocqué & Baert, 2002: 111, fig. 29A–B; figs 34C–F; 36A–D; 37A–B; 38C–F; 40A–B; 42A–D; 43A–B; 44A–F; 46A–D; 47A–B), but can be distinguished by large median apophysis, shorter, strongly recurved posterior branch (pMA); large retrolateral tibial apophysis with laminar posterior branch (pRTA), almost as long as anterior branch (aRTA), narrowing to apex ( Figs 42A–D ; 43A–B ; 44A–F ).
