Draculoides SCH 083: Abrams et al. 2019 MPE 106532: 8, fig. 2.

Material examined. Holotype female. AUSTRALIA: Western Australia: Middle Robe, Robe Valley, ca. 18 km ESE. of Pannawonica , 22°23’18”S, 116°15’11”E, 13–16 October 2008, troglofauna trap, J. Alexander (Biota Environmental Sciences, CWRC281 P4 T2–1 ) ( WAM T138570 ) (DNA: 12S, COI, 18S, 28S, ITS2 ). GoogleMaps

Diagnosis. Males are unknown. Females of Draculoides minae differ from all other known Draculoides in their distinctive spermathecae, which have roughly rectangular, non-plicate lobes. Female flagellum is unknown. Draculoides minae can be diagnosed from all other Draculoides species that were sequenced at COI, 12S and ITS2 by the 50bp mini-barcodes shown in Figures 3 View FIGURE 3 , 5 View FIGURE 5 , and 7.

Description (adult female). 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 + 1 setae; eye spots absent. Mesopeltidia separated. Metapeltidium divided. Anterior sternum with 15 setae (including 2 sternapophysial setae); posterior sternum triangular with 8 setae.

Chelicera. Fixed finger with 2 large teeth plus 6 smaller teeth between these; proximal and distal teeth without small lateral teeth; membranous area between fixed and movable fingers with 3 large, lanceolate, terminally pilose setae (G1); G2 and G3 composed of 3 setae; internal face of chelicera with 5 short whip-like setae (G4); brush at base of fixed finger composed of 5 setae (G5A), each densely pilose in distal half and G5B composed of 7 setae; G6 with one seta; G7 composed of 4 setae. Movable finger serrula composed of ca.15 long lamellae, blunt guard tooth present subdistally; 1 small accessory tooth present.

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 0.64 × 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: 2: 2.

Female genitalia. Two pairs of spermathecae with roughly rectangular, equal-sized lobes, each pair connected basally before connection with bursa ( Fig. 33A View FIGURE 33 ); sparsely covered with small pores mainly in stalk; gonopod rectangular and slightly elongated.

Flagellum. Unknown, collected without flagellum.

Dimensions (mm). Holotype female ( WAM T138570 ): Body length 4.88. Propeltidium 1.29/0.65. Chelicera 0.77. Flagellum missing. Pedipalp: trochanter 0.50, femur 0.58, patella 0.62, tibia 0.56, tarsus 0.21, claw 0.13, total excluding claw 2.46.

Remarks. Draculoides minae is only known from a single bore in the Middle Robe area ( Fig. 1D View FIGURE 1 ).

Other names. WAM SCH083 ( Abrams et al., 2019).

Etymology. This species is named for the character Mina Harker in Bram Stoker’s book “Dracula.” Mina was temporarily made a vampire and instrumental in compiling the information to discover Dracula’s plans.
