According to the diagnosis made by Golovatch et al.(2012),males are recognized by lateral coxal process of the anterior gonopod being very slen- der ( Fig. 6C); slender and conical medial coxal process; posterior gonopod with axe-shaped flagellum extended and with microgranulate distal lobules ( Fig. 6D).   Distribution:  T. calvuspresents a tropical distribution ( Golovatch et al.,2012). In Brazil, the species has been recorded only in urban areas from states of Rio de Janeiroand Bahia( ca. 1,500 km).   Material examined: Bahia:  Salvador, campus UFBA[- 13.004364°S; - 38.508978°W], 2013, C.M.P.
