Karaops feedtime View in CoL sp. nov.

( Figs 13–14 View FIGURES 9 – 14 , 37 View FIGURE 37 )

Type material. Holotype: female, 115 km NNW of Newman [22˚19’4.32” S 119˚44’51.27” E, Western Australia, Australia], 24 March–28 April 2011, Phoenix Environmental Sciences, wet pitfall, (WAM T 111456).

Etymology. This species is named after the Australian band feedtime . It is to be treated as a noun in apposition.

Diagnosis. Females of K. feedtime sp. nov. can be differentiated from all other species using characters of the epigyne. Ventrally, there is a large median lobe, and dorsally, the ducts are long and narrow, curving multiple times ( Figs 13–14 View FIGURES 9 – 14 ). Whereas convoluted ducts are also found in K. forteyi sp. nov., a median lobe is absent ( Fig. 15 View FIGURES 15 - 22 ). Males are unknown.

Description. Female (holotype):

Colour. Dorsal shield of prosoma yellow-brown, with slightly darker marks laterally; sternum pale yellow; chelicerae yellow-brown with darker infuscations anteriorly and laterally; maxillae pale yellow-brown; labium pale brown, lightening distally; opisthosoma dorsally yellow-brown with darker markings; ventrally pale yellow-brown; legs with segments clearly annulated, but annulations do not completely encircle femora, legs darkening distally; annulations lighter in centres.

Prosoma. 0.81 times longer than broad; clypeus 0.13 high.

Eyes. PME larger than AME, PLE largest, ALE smallest; eye group width 1.42; eye diameters, AME 0.16, ALE 0.13, PME 0.23, PLE 0.36; interdistances AME-ALE 0.34, PME-PLE 0.30, ALE-PLE 0.27, AME-PME 0.04; ocular quadrangle AME-AME 0.16, PME-PME 0.48.

Sternum. 0.88 times longer than broad.

Chelicerae. Promargin with 3 teeth, retromargin with 2 teeth.

Female pedipalp. Claws with less than 6 teeth.

Epigyne ( Fig. 13 View FIGURES 9 – 14 ). Lateral lobes distinct; large median lobe, slightly diamond-shaped, truncated and lightly sclerotised posteriorly; small copulatory openings located laterally at widest part of median lobe.

Vulva ( Fig. 14 View FIGURES 9 – 14 ). Copulatory ducts narrow, somewhat asymmetrical, curving anteriorly, then anterodorsally, then posteromedially; two pairs of small spermathecae; one pair located between copulatory openings and where ducts begin to curve posteriorly; the second pair located after ducts curve posteriorly toward epigynal margin; crescent-shaped fertilsation ducts directed anterolaterally.

Opisthosoma. Without caudal setal tufts.

Legs. Leg I only slightly shorter than legs II and IV (Leg III missing); leg formula unknown (at least one leg missing); leg II longest; tarsal claws without teeth; spination: leg I, Fm pr 1-1-0, d 1-1-1, rl 0; Ti d 0, v 2-2 -2-2-2; Mt v 2-2 -2-2; leg II, Fm pr 0-0-1, d 1-1-1, rl 0; Ti v 2-2 -2-2-2; Mt v 2-2 -2-2; leg IV, Fm pr 0, d 1-1-1, rl 0; Ti v 1-1; Mt 0.

Measurements. Total length 7.21. Dorsal shield of prosoma length 2.82, width 3.50. Sternum length 1.45, width 1.64. Opisthosoma length 4.39, width 3.76. Pedipalp: Fm 0.84, Pt 0.52, Ti 0.55, Ta 0.84, (total) 2.75. Leg I: Fm 2.93, Pt 1.27, Ti 2.64, Mt 2.29, Ta 1.07, (total) 10.20. Leg II: Fm 3.61, Pt 1.34, Ti 2.89, Mt 2.54, Ta 1.18, (total) 11.56. Leg III: Absent. Leg IV: Fm 3.46, Pt 1.09, Ti 2.86, Mt 2.57, Ta 1.16, (total) 11.14.

Distribution. This species is known only from the type locality ( Fig. 37 View FIGURE 37 ).

Life history and habitat preferences. Unknown.

Remarks. Prosoma damaged, so measurements of the dorsal shield of the prosoma and the eyes may not be exact.
