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
,
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
); sparsely covered with small pores mainly in stalk; gonopod rectangular and slightly elongated.
Flagellum
. Unknown, collected without flagellum.
Dimensions (mm)
