Trachyjulus calvus (Pocock, 1893a)


Trachyjulus calvus (Pocock, 1893a) View in CoL ( Figs. 1D View Figure 1 , 6 View Figure 6 C-D)

Descriptive notes: Male, see Golovatch et al. (2012: 114, figs. 8-9).

Identification: T.calvus is easily separated from Brazilian species of Spirostreptida by having tergites longitudinally crested ( Golovatch et al., 2012: fig. 8) and the presence of posterior gonopod. 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 View Figure 6 ); slender and conical medial coxal process; posterior gonopod with axe-shaped flagellum extended and with microgranulate distal lobules ( Fig. 6D View Figure 6 ).

Distribution: T. calvus presents a tropical distribution ( Golovatch et al., 2012). In Brazil, the species has been recorded only in urban areas from states of Rio de Janeiro and Bahia (ca. 1,500 km).
