Diagnosis. Differs from D. judidenchae sp. nov. in having finely pustulose cuticle on the carapace, the longer, more slender serrate setae on the fang shield of females, and in having two pairs of spines ventrally on tibiae III; females also have shorter spermathecae and stronger spination on tibiae and metatarsi.
Etymology. The species is named after actress, Dame Helen Mirren.
