Males of Tenedos humboldti sp. n. , resemble T. dankittipakuli sp. n. , T. griswoldi sp. n. , T. tama sp. n. , and T. piedecuesta sp. n. , by wide retrolateral tibial apophysis (RTA); the shape of the median apophysis (MA) with laminar anterior branch (aMA); the presence of a basal retrolateral tibial apophysis (bRTA) ( Figs 77A–D ; 78A–B ; 80A–D ; 82A–D ; 83A–B ; 85A–D ; 86A–B ; 88A–D ; 89A–B ; 91A–D ; 92A–B ), but are distinguished by more complex abdominal spots patterns; anterior branch of retrolateral tibial apophysis (aRTA) very thin and longer than in latter species; longer and tapered posterior branch (pRTA); median apophysis with short projection on anterior branch ( Figs 88A–D ; 89A–B ).
