Body, ventral; C. Body, lateral; D. Flagellum, dorsal; E. Flagellum, ventral; F. Flagellum, lateral. The scale bar shown in image A is 2 mm and also applies to B and C and the scale bar shown in image D is 200 µm and also applies to E and F. Diagnosis. The shape of the male flagellum of Draculoides anachoretus most closely resembles D. affinis , D. bythius , D. cochranus , D. eremius , D. gnophicola , D. kryptus , D. mckechnieorum and D. warramboo , especially in the presence of a broad base. It differs from D. affinis , D. bythius , D. eremius , D. gnophicola , D. kryptus and D. mckechnieorum in the anterior position of dm4, well set back from the posterior margin (in line with dl 3 in D. bythius , D. gnophicola , D. eremius and D. kryptus , slightly anterior to dl3 and close to posterior margin in D. affinis and D. mckechnieorum ). It differs from D. cochranus by the posterior position of dm 4 in relation to dl1 (dm4 is level with dl 1 in D. cochranus ) and from D. warramboo in the anterior position of vm 5 in relation to dl1 (vm 5 in line with dl 1 in D. warramboo ). Females are most similar to D. immortalis but differ in the position of dm1 of the flagellum, which is slightly anterior to the annulus separating flagellomeres II and III in D. anachoretus and very close to the annulus in D. immortalis . Draculoides anachoretus can be diagnosed from all other Draculoides species that were sequenced at COI and 12S by the 50bp mini-barcodes shown in Figs. 3 and 5 . Draculoides anachoretus can be diagnosed from all other Draculoides species that were sequenced at ITS2 ( Fig. 7 ) except for D. bythius , D. eremius , D. gnophicola , D. kryptus , D. mckechnieorum , D. warramboo , D. immortalis , D. belalugosii , D. christopherleei , D. piscivultus and D. akashae , which are not distinguishable using the ITS2 mini-barcode. Description. Adult male (WAM T140985). Colour . Yellow-brown; propeltidium and pedipalps somewhat darker. Cephalothorax . Propeltidium with 2+1 apical setae in a triangular formation on anterior process and 2 + 1 + 2 setae; eye spots absent. Mesopeltidia separated. Metapeltidium divided. Anterior sternum with 15 setae (including 2 sternapophysial setae); posterior sternum triangular with 7 setae. Chelicera . Fixed finger with 2 large teeth plus 5 smaller teeth between these, including 1 tiny lateral tooth on proximal tooth; membranous area between fixed and movable fingers with 3 large, lanceolate, terminally pilose setae (G1); G2 composed of 8 setae; G3 composed of 4 setae; internal face of chelicera with 5 short whip-like setae (G4); brush at base of fixed finger composed of 7 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 17 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. 8 stout setae, without mesal spur; tarsus and tibia without spines; tarsal spur present; claw 0.30 × 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: 3, segment XII with small dorsal process ( ♂ only). Flagellum . Male: Dorsoventrally compressed ( Figs. 11 D–F, 12A–C); 2.08 × longer than broad; seta dm1 situated dorso-medially, closer to anterior margin; seta dm4 set back from posterior margin, anterior to dl3; dl1posterior to vl1; dl3 close to posterior margin; vm2 uneven, one anterior to vm1 and one posterior to vm1; vm5 situated closer to vl2 than to vm3; left vm3 slightly anterior to right vm3; five pairs of microsetae between vl1 and dl3. Dimensions (mm) . Male (WAM T140985): Body length 4.04. Propeltidium 1.19/0.65. Chelicera 0.73. Flagellum 0.45/0.22. Pedipalp: trochanter 0.38, femur 0.58, patella 0.60, tibia 0.42, tarsus 0.29, claw 0.09. Variation . Body length (males) 3.13–4.04 (n = 3). FIGURE 12. Draculoides anachoretus male (WAM T140985): A. Flagellum, dorsal; B. Flagellum, ventral; C. Flagellum, lateral. The scale bar is 0.1 mm and applies to A–C. Remarks. Harvey et al . (2008) named this species from several females and juveniles collected from Mesa A in the Robe Valley, Western Australia ( Fig. 1A ). Additional specimens, including three males that are described here, have since been collected from Mesa A.
