Diagnosis. Males of Tenedos peckorum Jocqué & Baert, 2002 , resemble those of T. henrardi sp. n. and T. guacharos sp. n., by having bifid median apophysis (MA), quadrangular-shaped anterior branch (aMA); complex retrolateral tibial apophysis (RTA) (see Jocqué & Baert, 2002: 111, fig. 29A–B; figs 34C–F; 36A–D; 37A–B; 39C–F; 40C–D; 42A–D; 43A–B; 44A–F), but differ by large median apophysis, posterior branch (pMA) longer than anterior one, straight; posterior branch of retrolateral tibial apophysis (pRTA) long, wide, with thin longitudinal furrow, small apical denticles on ventral edge ( Figs 34C–F ; 36A–D ; 37A–B ).
