Diagnosis. The shape of the male flagellum of Draculoides warramboo   most closely resembles D. affinis   , D. anachoretus   , D. bythius   , D. cochranus   , D. gnophicola   , D. eremius   , D. kryptus   and D. mckechnieorum   especially in the presence of a broad base. It differs from D. affinis   , D. eremius   , D. gnophicola   and D. kryptus   by the sub-distal placement of dm4 (close to distal margin in D. affinis   , D. eremius   , D. gnophicola   and D. kryptus   ), from D. anachoretus   and D. bythius   by the close proximity of dl1 and vl1 (far apart in D. anachoretus   a nd D. bythius   ), from D. cochranus   by the anterior position of vm3, close to vm1 and vm2 (vm3 is situated in the middle of the flagellum of D. cochranus   , midway between vm5 and vm1) and from D. mckechnieorum   by the more anterior position of dm4 which is not level with dl3 as in D. mckechnieorum   . Female flagellum is unknown. Draculoides warramboo   can be diagnosed from all other Draculoides   species that were sequenced at COI by the 50bp mini-barcode shown in Figure 3 View FIGURE 3 . Draculoides warramboo   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. immortalis   , D. belalugosii   , D. christopherleei   , D. piscivultus   and D. akashae   , which are not distinguishable using the ITS2 mini-barcode.

Description (adults). Colour. Yellow-brown; propeltidium and pedipalps 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 (♂), 7 (♀) setae.

Chelicera. Fixed finger with 2 large teeth plus 4 (♂), 4 (♀) smaller teeth between these and 1 lateral tooth on proximal large tooth; membranous area between fixed and movable fingers with 3 large, lanceolate, terminally pilose setae (G1); G2 composed of 6 (♂), 8 (♀) setae; G3 composed of 5 (♂) (♀) setae; internal face of chelicera with 3 (♂), 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 (♂), 9 (♀) setae; G6 with one seta; G7 composed of 4 (♂) (♀) setae.

Pedipalp. Without apophyses; trochanter with sharply produced ventro-distal extension, ventral margin with ca. 8 (♂), 7 (♀) stout setae, without mesal spur; tarsus and tibia without spines; tarsal spur present; claw 0.7 (♂) × 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–IX: 2 macrosetae + 4 microsetae: 3 macrosetae + 6 microsetae (microsetae in column): 2: 2: 2: 2: 2: 2: 2 (♂), 2: 2: 2: 2: 2: 4: 4 (♀); segment XII without small dorsal process.

Female genitalia. Two pairs of spermathecae with outer lobe sub-equal to inner lobe, each pair connected basally before connection with bursa ( Fig. 43D View FIGURE 43 ), distally round and smooth; sparsely covered with small pores; gonopod short, distally bifurcate.

Flagellum. Male: Dorsoventrally compressed 2 × longer than broad ( Figs. 41 View FIGURE 41 D–F, 43A–C); seta dm1 situated dorso-medially, slightly closer to anterior margin; seta dm4 situated close to posterior margin; dl1 between dl3 and vl1 but much closer to vl1; dl3 on posterior margin; vm2 situated slightly above vm1; vm5 situated on approximately same level as dl1, closer to vl2 than to vm5; at least three pairs of microsetae between vl1 and dl3. Female flagellum unknown, specimen collected without flagellum.

Dimensions (mm). Holotype male (WAM T139912): Body length 3.51. Propeltidium 1.10/0.42. Chelicera 0.69. Flagellum 0.38/0.19. Pedipalp: trochanter 0.54, femur 0.48, patella 0.48, tibia 0.42, tarsus 0.19, claw 0.13, total excluding claw 2.25.

Paratype female (WAM T138501): Body length 4.76. Propeltidium 1.56/0.83. Chelicera 0.96. Flagellum missing. Pedipalp: trochanter 0.75, femur 0.52, patella 0.67, tibia 0.65, tarsus 0.35, claw 0.10, total excluding claw 2.94.

Variation. Body length (males) 3.46–3.51 (n = 2).

Remarks. Draculoides warramboo   is known from several locations within two areas known as Warramboo and Tod Bore ( Fig. 1A View FIGURE 1 ). Warramboo is not a discrete mesa but appears to be the western extension of pisolitic geology from Mesa A ( Harvey et al., 2008), despite this, molecular data suggest no gene flow occurring between Warramboo and Mesa A ( Fig. 2 View FIGURE 2 ). Juveniles were sequenced by Harvey et al. (2008) but not named due to a lack of adult specimens. The specimens listed above are associated with this species by locality and, in two cases, by sequence data ( Fig. 1A View FIGURE 1 ).

Other names. WAM SCH057 ( Abrams et al., 2019).

Etymology. The specific epithet refers to the type locality, Warramboo. It is to be treated as a noun in apposition.
