Diagnosis

Males can be recognized by the pale coloured, stout bulb, without tiny conical projection and the nearly straight embolus, without a conductor ( Figure 9 (a), 9(b), fig. 20 in Grismado et al. 2011). Females can be recognized by the long anterior receptaculum, rounded posterior receptaculum and semicircular ridges (fig. 21 in Grismado et al. 2011).
