Cyperacarus foliatus   sp. nov. Beard & Ochoa

( Figs 20–21 View FIGURE 20 View FIGURE 21 )

Types. Holotype. Ƥ. Australia, Queensland, Hook Point to Dilli Village Road, Great Sandy National Park, Fraser Island, 25 ° 41 ’ 46 ” S 153 °04’ 22 ” E, 02.ix. 2004, ex. red-fruited saw sedge Gahnia sieberiana Kunth.   var. sieberiana   ( Cyperaceae   ) ( BRI voucher PIF 30171 View Materials ), J.J. Beard & P.I. Forster (QM, UQIC # 59686).

Diagnosis. Adult female ( Figs 20–21 View FIGURE 20 View FIGURE 21 ). As per genus, in addition to: setae c 1 and d 1 minute, smooth; dorsal lateral opisthosomal setae broad. Male unknown.

Immatures. Unknown.

Adult female. (1 measured)

Dorsum. ( Fig. 20 View FIGURE 20 ) Body measurements: v 2 –h 1 286 (tip of anterior projection to h 1 324), sc 2 –sc 2 91, c 3 –c 3 108, f 2 –f 2 56. Dorsal cuticle mostly smooth, with few transverse grooves and folds between setae sc 2 and c 1. Dorsal shield or dorsal thickening evident, marked laterally by a change in cuticle. Anterior margin of prodorsum with three projections—a broad, rounded central projection, flanked by two smaller lateral projections each bearing setae v 2. Lateral setae sc 1, c 3, d 3, e 3, f 2 inserted on rounded tubercles. Setae sc 1, h 2 elongate, barbed with minute distal club; c 1, d 1, h 1 minute; all other dorsal setae broad, dorsoventrally flattened, with strong lateral barbs; dorsal surface of setae finely spiculate, ventral surface smooth: v 2 25 – 27, sc 1 242 – 258, sc 2 34 – 35, c 1 4, c 3 32 – 33, d 1 4, d 3 35 – 37, e 3 37, f 2 36, h 1 2 – 3, h 2 173 – 176.

Gnathosoma   . ( Fig. 20 View FIGURE 20 ) Gnathosoma   extends to middle of genu I. Dorsal cuticle with longitudinal plicae; ventral cuticle finely papillate medially; longitudinal plicae between setae 1 b– 1 a. Ventral setae m absent. Palps 3 -segmented; 0, 2, 0(2); tibia with two setae (d 14, v 10 – 11); tarsus with two eupathidia (8 – 9; 4). Cheliceral stylet length from curve of hook to anterior tip 107.

Venter. ( Fig. 21 View FIGURE 21 ) Cuticle completely plicate, covered with fine, transverse plicae between setae 1 a–g 2; some anterior longitudinal plicae between setae 1 b– 1 a; plicae on genital flap transverse, arching anteriorly around setae g 1 –g 2. Setae g 1 inserted in an anterior position to g 2 on genital flap. All setae fine, smooth; setae 1 a, 1 b, 4 a 1, 4a2 elongate, fine (difficult to consistently determine full length). Setal measurements: 1a 56 – 72, 1 b 50, 2 b 14 – 18, 2 c 17 – 20, 3 a 20 – 24, 3 b 13 – 16, 4 a 1 78, 4 a 2 71, 4 b 16 – 18, ag 12 – 17, g 1 14 – 17, g 2 19 – 21, ps 1 9 – 10, ps 2 7 – 8.

Spermatheca. ( Fig. 21 View FIGURE 21 ) Cylindrical vesicle (14).

Legs. ( Fig. 20 View FIGURE 20 ) Setal formulae for legs I – IV: 1 - 0-3 - 0-5 - 7 (1), 2 - 0-3 - 0-5 - 7 (1), 1 - 0-2 - 0-3 - 3, 1 - 0-2 - 0-3 - 3 respectively. Tarsi I and II each with one short antiaxial solenidion ω ’ (4, 3 respectively) and two distal eupathidia p ζ ’- p ζ ’’ (7 – 8, 6 – 7; 7 – 8, 6 – 7 respectively); ta I – IV with u’-u’’ asymmetrically barbed.

Colour. This species is orange with small black spots internally (presumed to be food in gut).

Male. Unknown.

Remarks. As only one specimen is known for this species, the true range and variability of measurements remains unknown. The tip of the spermathecal apparatus is truncate and presumed to be damaged.

Etymology. The masculine Latin word “ foliatus   ” means “leafy” and refers to the leaf-like setae on the opisthosoma of this species.
