Diagnosis. Females are unknown. The shape of the male flagellum of Draculoides christopherleei   is distinctive due to its small lateral lobes, very broad stalk and the absence of dl1. Draculoides vinei   is the only other Draculoides   species lacking dl1 but clearly differs from Draculoides christopherleei   in the shape of the male flagellum, which is dorsolaterally compressed in Draculoides vinei   and dorsoventrally compressed in Draculoides christopherleei   . Draculoides christopherleei   can be diagnosed from all other Draculoides   species that were sequenced at COI and ITS2 by the 50bp mini-barcodes shown in Figures 3 View FIGURE 3 and 5 View FIGURE 5 . Draculoides christopherleei   can be diagnosed from all other Draculoides   species that were sequenced at ITS2 ( Fig. 7 View FIGURE 7 ) except for D. anachoretus   , D. bythius   , D. eremius   , D. gnophicola   , D. kryptus   , D. mckechnieorum   , D. warramboo   , D. immortalis   , D. belalugosii   , D. piscivultus   and D. akashae   , which are not distinguishable using the ITS2 mini-barcode.

Description (adults). Colour. Pale yellow-brown; propeltidium, pedipalps and flagellum somewhat darker.

Cephalothorax. Propeltidium with 2+1 apical setae in a triangular formation on anterior process and 2+2+2 setae; eye spots absent. Mesopeltidia separated. Metapeltidium divided. Anterior sternum with 12 (♂) setae (including 2 sternapophysial setae); posterior sternum triangular with 6 setae.

Chelicera. Fixed finger with 2 large teeth plus 4 smaller teeth between these; membranous area between fixed and movable fingers with 3 large, lanceolate, terminally pilose setae (G1); G2 composed of 5 setae; G3 composed of 6 setae; internal face of chelicera with 5 short whip-like setae (G4); brush at base of fixed finger composed of 8 setae (G5A), each densely pilose in distal half and G5B composed of 10 setae; G6 with one seta; G7 composed of 3 setae. movable finger serrula composed of ~16 long lamellae, blunt guard tooth present subdistally; 1 large accessory tooth present.

Pedipalp. Without apophyses; trochanter with sharply produced ventro-distal extension, ventral margin with ca. 7 stout setae, without mesal spur; tarsus and tibia without spines; tarsal spur present; claw 0.27 × length of tarsus.

Legs. Tarsus I with 6 segments; baso-dorsal margin of femur IV produced at about a 90° angle.

Abdomen. Chaetotaxy of tergites I: 2 macrosetae + 4 microsetae (microsetae diagonal), tergite II: 3 macrosetae + 6 microsetae (microsetae in column), tergites III–IX: 2: 2: 2: 2: 2: 2: 3; segment XII with small dorsal process (♂ only).

Flagellum. Moderately dorsoventrally compressed ( Figs. 18 View FIGURE 18 D–F, 19A–C), with small lateral lobes, very broad stalk; in lateral view, dorsal margin very slightly concave with very slight dorsal concavity above vl1 terminating in small distal triangular tip; ventral margin evenly convex with shallow concavity between vm3 and vl2; 2.13 × longer than broad; seta dm1 situated dorso-medially, slightly closer to anterior margin; seta dm4 anterior to dl3; dl1 absent; dl3 on posterior margin; vm2 situated slightly anterior to vm1; paired vm3 staggered, with right seta below left; vm5 situated slightly posterior to dl1, closer to vm3 than vl2; 6 pairs of microsetae near anterior end, and three pairs between vl1 and vl2.

Dimensions (mm). Holotype male (WAM T129676): Body length 3.13. Propeltidium 0.88/0.58. Chelicera 0.48. Flagellum 0.33/0.15. Pedipalp: trochanter 0.46, femur 0.44, patella 0.50, tibia 0.42, tarsus 0.25, claw 0.07, total excluding claw 2.14.

Remarks. Draculoides christopherleei   is known from several locations within the Buckland Hills area, situated in the eastern Hamersley Range, Western Australia ( Fig. 1E View FIGURE 1 ). The partial specimens listed above are associated with this species by locality and, in some cases, by sequence data ( Fig. 1E View FIGURE 1 ).

Other names. WAM SCH080 ( Abrams et al., 2019), Bennelongia B40.

Etymology. This species is named for actor Christopher Lee (1922–2015) who played the role of Dracula in the 1958 movie “Horror of Dracula” and the 1970 movie “Count Dracula.”
