Diagnosis. Males of Tenedos macagual sp. n. resemble those of T. hoeferi Jocqué & Baert, 2002 and T. ticuna sp. n., by having a developed conductor (C), curving at prolateral region, where it is very thin (see Jocqué & Baert, 2002: 100, fig. 18A–E; figs 22A–D; 23A–B; 32A–D; 33A–B), but can be recognized by their bifid retrolateral tibial apophysis (RTA) with short and thin anterior branch (aRTA), and long, concave and straight posterior branch (pRTA); long and laminar median apophysis (MA), ending as three short tips ( Figs 32A–D ; 33A–B ). Females are characterized by having very long seminal receptacles (SR), bending over on themselves, large spermathecae (S), small median field plate (MFP), and short and posteriorly situated lateral borders (LB), delimiting a quadrangular atrium (A) ( Figs 32E–F ; 33C–D ).
