Costa Rica: Monteverde.
I know this species from one worker series from Monteverde. Steve Yanoviak and colleagues carried out a canopy fogging study in the Monteverde cloud forest, and Lisa Schonberg prepared and identified the ants. She discovered a long workers series of this species in samples from one of the fogged trees. The tree was a relict tree in a pasture at 1500m.
This species appears to be rare in Monteverde, given abundant collecting in the region. It is curiously similar to another Monteverde species, JTL-006, differing mainly in color. This species is black and JTL-006 is orange. JTL-006 is known from one worker collected at 1200m on the Bajo Tigre trail, just below the site where JTL-007 was collected.
This species appears most similar to T. fuscatus (Mann 1920), which is known only from the types [Macromischa (Macromischa) fuscata Mann 1920:420. Syntype worker: Guatemala, Antigua, December 1911 (W. M. Wheeler), ex hollow twig.]. It matches the figures and the key in Baroni-Urbani (1978).
