Diagnosis

Males can be differentiated from all other species by the embolus, which originates at 6 o'clock, a long process on the MA, and the RTA, which is on a very long stalk and has a very large quadrangular process distally (Figs 61-62). Females can be separated from other species by the posterior margin of the epigynum which is sinuous and heavily sclerotized, with a median septum that is wider anteriorly, and a posterodorsal fold that is sinuous (Figs 63–64).
