Diagnosis. Differs from D. helenmirrenae sp. nov. in having enlarged pustules on the carapace, and in the unusual spination ventrally on tibiae III. Females also have longer spermathecae, short thick spine-like serrate setae on the fang shield, and weaker spination on the tibiae and metatarsi.
Etymology. The species is named in honour of actress, Dame Judi Dench.
Description holotype male QM S29523. As D. helenmirrenae except:
Carapace 2.12 long, 1.60 wide. Abdomen 2.28 long, 1.60 wide. Total length 4.4.
Colour: carapace brown with light cover of broad white hairs. Coxae all yellowish; femora brown with yellowish basal half; patellae-tarsi I and II yellowish, III and IV orange brown; abdomen dorsal dark red brown scute with two pairs of pallid transverse bands also bearing white hairs, and pair of pallid spots posteriorly; genital and ventral scute orange brown; laterally abdomen black with three pallid marks. Carapace: margin smooth; distinct pustules in donut-shaped zone of thorax around fovea. Chelicerae: with 3–4 short thick serrate setae on fang shield. Legs: white and black feathery hairs on femora and tibiae. Shallow notches on trochanters IV. Spines: weak on tibiae and metatarsi I and II. I: fe p1d2; ti 0; me v2.2(w). II: fe d2; ti v0.1; me v2.2(w). III: fe p2d3r1; ti p2r2v1.2; me p2r2v2. IV: fe p2d3r1; ti p2r2v1.2.2; me p3r3v2.2.3. Palp: fe p1d2. Tibiae III with enlarged megaspine centroventrally; two basal spines ventrally on metatarsi III short, thorn-like. Palp: paracymbial spine clearly subbasal; embolus tip twisted; cymbium with weak dorsal scopula and two thick setae apically. Abdomen: petiolar collar short; entral scute with convex edges and converges from base.
Female allotype QM S39420, like ♂ except:
Carapace 1.72 long, 1.35 wide. Abdomen 1.95 long, 1.48 wide. Total, 4.1.
Colour: carapace brown, few white hairs on slope and black bristles; abdomen dorsally mottled brown, broad trianguloid almost glabrous scute for one-fifth, behind that two large pairs of pallid sigilla, back pair in broken field of white, transverse slender pallid bars, laterally with pallid longitudinal grooves, ventrally light brown with two paler longitudinal bars centrally. Carapace: dark shallow cordate depression in front of fovea along anteromedial ridge. Chelicerae with 3–4 thick black tapering fang setae; dentition 2R, 3P. Sternum with domed edges, with shallow but wide medial and radial grooves. Epigyne: two small spiral-ridged fossae set wide (ca. 3–4 diameters apart) lead to short recurved copulatory ducts to large head of spermathecae, folding to narrow dorsal and slightly enlarged basal spermathecae. Abdomen: tracheal scute subquadrate with ca. 20 short thick black setae.
Distribution and Habitat. Known only from rainforests in south-eastern Queensland.
