Wandella stuartensis Gray 1994 (Figures 3 – 8, 12, 13 F – H, 15, 25 – 27) Wandella stuartensis

Gray 1994, p. 54, figs 8, 65 – 70, 80.

Male holotype from Lagoon Waterhole, Mabel Creek Station, SA, 28 ° 56 ' S, 134 ° 19 ' E, 26 /X/ 1984, P. Greenslade, in pitfall trap, deposited in SAM ARA 5311 (2), not examined.

Diagnosis

Male (Figure 25) diagnosed by Gray (1994). Females can be distinguished by the combination of the following: the enlarged, usually longer than wide, bases of the spermathecae; the lack of a clear distinction between the base and the inner spermathecae; and the rounded outer spermathecae, on the top of a short, laterally directed stalk (Figure 26 E – H).

Description

Male (Figure 25) described by Gray (1994).

Female from Paroo-Darling National Park, New South Wales, Australia (AM KS. 114345) (Figure 26 A – E). Coloration: carapace cream, with dark brown median pattern and clypeal markings, and light brown median area, with slightly dark submarginal bands; chelicerae cream with an anterior brown patch; labium and endites light yellow; sternum cream with diffuse light brown patches along the anterior border; legs light yellow, with incomplete light brown rings in the base and apex of the femora, tibiae and metatarsi and a prolateral light brown patch on the patellae; abdomen dorsum light brown, clothed with whitish setae, with dark brown chevron with five markings posteriorly; abdomen venter cream, darker posteriorly. Sternum subrounded, with a well-marked pair of posterior sigillae. Total length 3.65. Carapace length 1.47, width 1.16. Clypeus length 0.27. Eye diameters and interdistances: AME 0.08, PME 0.07, ALE 0.11, PLE 0.78, AME – AME 0.03, PME – PME 0.14. Palp: femur length 0.8, width 0.26, tibia length 0.54, width 0.26. Right leg I: femur 1.68, patella 0.39, tibia 1.83, metatarsus 1.49, tarsus 1.06. II: fe 1.16, pa 0.39, ti 1.01. III: fe 1.05, pa 0.38, ti 0.85. IV: fe 1.45, pa 0.39, ti 1.36, mt 1.19, ta 0.75. Abdomen: length 2.04, width 1.24. Leg macrosetae: absent. Calamistrum with three rows, the middle one slightly reduced (~ 5 setae, others ~ 6 – 7). Epigastric furrow adorned with thick setae, slightly longer towards the laterals. Spermathecae: inner spermathecae rounded, somewhat sclerotized, outer spermathecae about the same size as inner, not so sclerotized, on a short stalk. State of the specimen: missing left leg I from the tibia.

Variation

Females (n = 4): total length 2.75 – 3.65 (3.31), carapace length 1.03 – 1.47 (1.21), femur I length 1.21 – 1.68 (1.39), tibia I length 1.23 – 1.83 (1.46), tibia/carapace ratio 1.13 – 1.24 (1.19). The morphology of the spermathecae is variable, especially in the base: some specimens have it short and wider, while others have it longer and narrower (Figures 26, 27). The morphology of the male palp is variable as well (Figure 25), although all specimens fit to Gray ’ s (1994) original diagnosis. This is a small, widely distributed species that might have to be split after a more careful revision.

Note

Males and females have been matched because they have been collected several times from the same localities.

Distribution

Arid regions of Western Australia, South Australia, New South Wales and southwestern Queensland (Figure 15).
