description: Kochosa sharae sp. nov.
(Figs 20, 22A–E)
Holotype. Male, Flinders Chase National Park, 4 km W Rocky River Headquarters, Kangaroo Island (35º 57'00''S 136º42'30''E, South Australia, AUSTRALIA), E. G. Matthews, J. A. Forrest, 1–7 November 1990 (SAM NN13502).
Etymology. The specific epithet is a matronym honouring a good friend of the senior author, Shar Ramamurthy, currently Senior Manager, Environmental Water at the Department of Environment, Land, Water and Planning (Victoria), for her support during the mutual times at Melbourne University.
Other material examined. Australia: South Australia: 2 males, Snug Cove, 9 km NNE, Kangaroo Island, 35º47'19''S 136º48'59''E (NN13503–4).
Diagnosis. Male pedipalp morphology of K. sharae sp. nov. is similar to that of K. fleurae sp. nov., both sharing a digitiform basoembolic apophysis; however, it is comparatively smaller and more curved in K. sharae sp. nov. (Fig. 22E).
Description.
Male (based on holotype, SAM NN13502).
Cephalothorax. Dorsally dark brown; broad median light band narrowing posteriorly; lateral light bands distinct; white setae throughout (Fig. 22A). Sternum dark brown with few white setae (Fig. 22B).
Abdomen. Dorsally dark olive brown; cardiac mark continuous, narrowest posteriorly and there bordered by black spots (Fig. 22A). Venter light olive-brown, anteriorly somewhat darker (Fig. 22B).
Pedipalps (Figs 22C–E). Patella of distinct light brown colouration with white setae; tegular apophysis round lobe, almost translucent; basoembolic apophysis digitiform and curved; embolus straight medially, curved basally and then apically. (Fig. 22E)
Legs. Brown with darker annulations; spination of leg I: femur. 2 dorsum, 1 apicodorsal, 1 apicoprolateral, 1 apicoretrolateral (very small); tibia. 3 ventral pairs, 2 prolateral, 2 retrolateral; metatarsus. 3 ventral pairs, 1 apicoventral, 2 prolateral, 1 apicoprolateral, 2 retrolateral, 1 apicoretrolateral.
Measurements: TL 4.84, CL 2.67, CW 1.99. Eyes: AME 0.10, ALE 0.10, PME 0.24, PLE 0.23. Row of eyes: AE 0.64, PME 0.76, PLE 0.96. Sternum (length/width) 1.21/0.99. Labium (length/width) 0.36/0.38. AL 2.17, AW 1.49. Legs: Length of segments: Pedipalp 1.00+0.91+-+0.81=2.72, I 1.80+2.01+1.44+0.96=6.21; II 1.68+2.04+1.4 6+0.96=6.14, III 1.68+1.84+1.56+0.91=5.99; IV 2.06+2.32+2.30+1.24=7.92.
Variation. Size (range, mean ± s.d.): TL 4.60–4.84, 4.75 ± 0.13; CL 2.65–2.72, 2.68 ± 0.04; CW 1.85–1.99, 1.91 ± 0.07, n = 3. One of the males was much darker than the one illustrated here and with less distinct median carapace band and abdominal cardiac mark.
Female. Unknown.
Life history and habitat preferences. There is no information on the habitat of this species; the three males of K. sharae sp. nov. were found between October to November suggesting this to be a spring-mature species.
Distribution. Kochosa sharae sp. nov. is only known from western Kangaroo Island, South Australia (Fig. 20).
