Glyphiulus granulatus (Gervais, 1847) ( Figs. 1C , 4 C-D, 6B)

Descriptive notes: See Golovatch et al. (2007: 12, figs. 1-6).

Identification: Males of G. granulatus are recognized by a median outgrowth of the coxosternum in the anterior gonopods ( Golovatch et al., 2007: fig. 5a, b; Fig. 6B ) and the typical pattern of carinotaxy. As in T. calvus , the species is easily identified when compared with Brazilian species of Spirostreptida by having tergites longitudinally crested ( Fig. 4 C-D) and the presence of posterior gonopod (see Golovatch et al., 2007: 12).

Distribution: G. granulatus has been recorded in SE Asia and in islands in the Pacific and Indian oceans ( Shelley, 1998a; Jeekel, 2004; Korsós, 2004; Enghoff et al., 2015). In Brazil, the species occurs only in urban areas in Santa Maria, state of Rio Grande do Sul.
