It may be easily differentiated from  Trichobius dugesioidesWenzel 1966, to which it is related, by the extremely long antescutellar bristles, some of which are three or four times as long as the scutal setae immediately anterior to them (less than twice as long in  T. dugesioides); the extensive microsetose area on the prescutum; and the male gonapophyses are long and feebly curved in the lateral view (Wenzel et al.,1966; Graciolli & Carvalho, 2001).   Comments:This species was recorded in Argentinaby Autino et al.(2018). Although the host bat for the typespecimen is  Desmodus rotundus(Phyllostomidae), it has been also reported on other species of Phyllostomidae, such as  Carollia perpicillata,  Diphylla ecaudataSpix, 1823and  Glossophaga soricina(Pallas, 1766), and on the Molossidaespecies  Molossus molossus(Pallas, 1766).
