Identification. Females of T. opacus were identified by the posterior margin of abdominal sternite VII roundly projected in the middle, surpassing the acute and laterally curved spinose projections of the last abdominal laterotergites. Males were recognized by the following combination of characters: fore femur not widened on basal half, without protuberance or tubercle on posterior surface; proctiger elongated, with distal half subtriangular; and pygophore with 2 small teeth on dorsolateral margin, without large dorsal projection ( Mondragón et al. 2017).

Distribution in the Colombian Caribbean region. Cesar ( Aristizábal-García 2002, Morales-Castaño and Molano-Rendón 2009), Córdoba ( Aristizábal-García 2002), Magdalena ( Molano-Rendón et al. 2005), Sucre ( Aristizábal-García 2017, this work).
