Diagnosis. Males are unknown. Females differ from all other Draculoides by the anterior placement of dl1 to vl1 of the flagellum (all others are posterior to vl1) and by the circular gonopod of the genitalia. Draculoides carmillae can be diagnosed from all other Draculoides species that were sequenced at COI and 12S by the 50bp minibarcodes shown in Figures 3 View FIGURE 3 and 5 View FIGURE 5 . Draculoides carmillae can be diagnosed from all other Draculoides species that were sequenced at ITS2 ( Fig. 7 View FIGURE 7 ) except for D. nosferatu , D. claudiae , D. carmillae and D. mesozeirus , which are not distinguishable using the ITS2 mini-barcode.

Description (adult female). Colour. Yellow-brown.

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 13 setae (including 2 sternapophysial setae); posterior sternum triangular with 6 setae.

Chelicera. Fixed finger with 2 large teeth plus 7 smaller teeth between these, proximal tooth with 1 tiny lateral tooth and distal tooth without small lateral teeth; 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 11 setae; G6 with one seta; G7 composed of 1 seta. Movable finger serrula composed of 17 long lamellae, small blunt guard tooth present subdistally; 1 large accessory tooth present at two-thirds from base of serrula.

Pedipalp. Without apophyses; trochanter with sharply produced ventro-distal extension, ventral margin with ca. 9 stout setae, without mesal spur; tarsus and tibia without spines; tarsal spur present; claw 0.69 × 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: 2 macrosetae + 6 microsetae (microsetae in column), tergites III–IX: 2: 2: 2: 2: 2: 4: 4.

Female genitalia. Two pairs of spermathecae with equal-sized lobes, each pair connected basally before connection with bursa ( Fig. 17G View FIGURE 17 ), distally round and smooth; sparsely covered with small pores; gonopod short and circular.

Flagellum. 5× longer than broad ( Figs. 16 View FIGURE 16 D–F, 17A–C); seta dm1 situated towards posterior end of flagellomere II slightly anterior to vm2; setae dl1 small, one anterior to the other, situated anterior to dm4, dm4 situated almost at middle of flagellomere III; dl3 situated near posterior margin, slightly posterior to vl2; vm1 situated between vm2, on the same level as vm2; vm3 situated slightly closer to vm1 than to vm5; vm5 halfway between vm3 and vl2; vl1 situated posterior to vm3 and anterior to right dl1; 1 pair of microsetae anterior to vl2, 1 pair of microsetae close to annulus separating flagellomeres II and III.

Dimensions (mm). Holotype female (WAM T138484): Body length 4.18. Propeltidium 1.06/0.77. Chelicera 0.77. Flagellum 0.37/0.08. Pedipalp: trochanter 0.60, femur 0.67, patella 0.77, tibia 0.67, tarsus 0.25, claw 0.12, total excluding claw 3.05.

Paratype female (WAM T138517): Body length 3.56. Propeltidium 1.04/0.69. Chelicera 0.69. Flagellum 0.38/0.08. Pedipalp: trochanter 0.56, femur 0.56, patella 0.67, tibia 0.62, tarsus 0.25, claw 0.12, total excluding claw 2.65.

Variation. Body length (females) 3.56–4.18 (n = 2).

Remarks. Draculoides carmillae is known from a single site in the Middle Robe area of the Robe River Valley, Western Australia ( Fig. 1D View FIGURE 1 ). The juvenile specimen listed above is associated with this species by locality ( Fig. 1D View FIGURE 1 ).

Other names. WAM SCH059 ( Abrams et al., 2019).

Etymology. The specific epithet refers to Carmilla, one of the first fictional vampires, in Joseph Sheridan Le Fanu’s novella “The Dark Blue.”
