Relationships. This species is morphologically closely similar to T. quadrijuga , but this is not supported by the ITS data which separates them widely. In this case the geographical distribution is a better indicator of relationship, as the species is placed in a small clade of mostly coastal Brazilian species including T. ramalhoi , and T. pseudostipularis (25307),
