Diagnosis. Adult males differ from all other species of the genus by the combination of the following characters: sternite of seventh body ring without ventral projections, presence of a large lateral expansion in the solenomere ( Figs 21D–E ) and the prefemoral process not involving the solenomere, in ectal view ( Fig. 21E ).
