Males are unknown. Females are morphologically indistinguishable from other species of Draculoides . Draculoides akashae can be diagnosed from all other Draculoides species that were sequenced at 12S by the 50bp mini-barcode shown in Figure 5 . Draculoides akashae can be diagnosed from all other Draculoides species that were sequenced at ITS2 ( Fig. 7 ) except for D. anachoretus , D. bythius , D. eremius , D. gnophicola , D. kryptus , D. mckechnieorum , D. warramboo , D. immortalis , D. belalugosii , D. christopherleei and D. piscivultus , which are not distinguishable using the ITS2 mini-barcode. Description (adults). Colour . Pale yellow-brown; propeltidium somewhat darker. Cephalothorax . Propeltidium with 2+1 apical setae in a triangular formation on anterior process and 2+2 setae; eye spots absent. Mesopeltidia separated. Metapeltidium divided. Anterior sternum with 13 setae (including 2 sternapophysial setae); posterior sternum triangular with 7 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 6 setae, G3 composed of 5 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 8 setae; G6 with one seta, G7 composed of 4 setae. Movable finger serrula composed of 18 long lamellae, blunt guard tooth present subdistally; 1 large and 1 tiny 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 0.50 × length of tarsus. Legs. Tarsus I with 6 segments; baso-dorsal margin of femur IV produced at about a 90° angle. Abdomen . Chaetotaxy of tergite 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: 2; segment XII with tiny dorsal process. Female genitalia . Two pairs of elongate spermathecae with outer lobes smaller and narrower than inner lobes, each pair connected basally before connection with bursa ( Fig. 10D ), distally round and smooth; sparsely covered with small pores; gonopod short, distally slightly bifurcate. Flagellum . Male: unknown. Female: 4.25 × longer than broad; seta dm1 situated slightly more posterior to vm2; setae dl1 small, situated close to vl1, dm4 situated midway between vl1 and dl3; dl3 situated almost at posterior margin slightly more posterior than vl2, vm1 situated slightly more posterior than vm2, vm3 situated closer to vm1 than to vm5, vm5 halfway between vm3 and vl2, vl1 situated posterior to vm3 and anterior to dl1; 1 pair of microsetae baso-laterally on flagellomere III. Dimensions (mm) . Holotype female (WAM T96159): Body length 3.89. Propeltidium 1.00/0.63. Chelicera 0.73. Flagellum 0.4/0.19. Pedipalp: trochanter 0.52, femur 0.52, patella 0.58, tibia 0.50, tarsus 0.17, claw 0.09, total excluding claw 2.37. FIGURE 9. Draculoides akashae sp. nov. , holotype female (WAM T96159): A. Body, dorsal; B. Body, ventral; C. Body, lateral; D. Flagellum, dorsal; E. Flagellum, ventral; F. Flagellum, lateral. The scale bar shown in image A is 1 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. Paratype female (WAM T96166): Body length 4.42. Propeltidium 1.27/0.79. Chelicera 0.69. Flagellum 0.17/0.05. Pedipalp: trochanter 0.48, femur 0.54, patella 0.58, tibia 0.54, tarsus 0.25, claw 0.13, total excluding claw 2.51. Variation. Anterior sternum number of setae 13–15, including sternapophysial setae (n=3 incl. holotype ). Body length (females) 3.89–4.09 (n = 3). Remarks. Draculoides akashae is only known from Mesas H and J, situated in the Robe Valley, Western Australia ( Fig. 1B ). The juvenile specimens listed above are associated with this species by locality and, in many cases, by sequence data ( Fig. 1B ). Draculoides akashae co-occurs with D. piscivultus at Mesa H. Females of D. akashae and D. piscivultus have very similar genitalia and flagellums but D. akashae’s spermathecae are more plicate, more uniformly broad and have a smaller stalk than those of D . piscivultus , and the flagellum differs in ventral view with vl1 equidistant from vm3 and vm5 (vl1 is closer to vm3 than to vm 5 in D. piscivultus ). Additionally, while these species co-occur in the same landform (Mesa H) and the females have subtle morphological differences, they are distantly related phylogenetically, and were placed in two distinct clades ( D. akashae : Clade G, D. piscivultus : Clade L). Other names . WAM SCH098 ( Abrams et al ., 2019 ), Helix code SCH011. Etymology. The specific epithet refers to the fictional character Akasha, queen of the vampires in Anne Rice’s book “Queen of the damned.”
