Genus Guaporeptus Hoffman, 1988

Guaporeptus Hoffman, 1988a: 327 .

Type species: Guaporeptus paradisius Hoffman, 1988 , by monotypy.

Diagnosis: Modified after Hoffman (1988a). Specimens of Guaporeptus resembles those of Urostreptus Silvestri, 1897 by presence of keel-shaped projection on epiproct ( Fig. 3B, D ); paraproct with broadened edge. Males of Guaporeptus can be easily distinguished by broad, birdhead-shaped distolateral metaplical process (dmp); very short antetorsal process (atp); telopodite with two complete 360° torsions (tp) ( Figs. 7 A-B; 8D). First leg-pair with subtriangular, glabrous prefemoral process (pfp) ( Fig. 6 C-D).
