Also first group. The female holotype of T. trigonum from north-western Brazil (Amazonas) has tegmina with uniform margins (the paratype from the Loreto Region in northern Peru apparently as well). The female holotype of T. quadriincisum from northern Peru (also Loreto Region) shows identical tegmen shape and venation, except for the eponymous four emarginations near the tip (photos of both specimens in OSF).
