Remarks. – This species was described from a unique ♀ holotype, which unfortunately is deposited in the personal collection of O. Zompro (Berlin) and unfortunately is not accessible for examination. The insufficient description and availability of merely one habitus photo do not allow any proper taxonomic positioning of the species. The distinctive character “abdominal sternite VII with a notch posteromedially”, that according to Zompro (2004:214) separates this species from T. echinatus (Stål, 1877) does not properly distinguish gatla from this species or other congenerics, because all known species have a posteromedian notch or emargination on sternum VII. Nor does the eponymous characteristic feature mentioned “Supraanal plate with a notch posteromedially” help in distinguishing gatla reliably from other species, because this feature is seen to underlie slight variability within individual species and is also true also for echinatus and other species in the genus. Thus,the differentiation from echinatus given by Zomproisalso notappropriate (i) due tothe fact that the specimens listed and illustrated as echinatus (Zompro, 2004: 213, fig. 124a) were misidentified and actually represent T.mangyan n. sp.,
