Other material examined: Ninety-four males, 23 females, and 29 juveniles from 152 records (Appendix S1).

Diagnosis: Females and immature males can be readily distinguished from all other Hoggicosa species   by the distinct leg coloration and abdominal pattern ( Fig. 1D View Figure 1 ). This pattern consists of light femora, tarsi, and metatarsi, with black patellae and tibiae, with a pale stripe along either side of the abdomen from the spinnerets. The male palp is most similar to that of H. brennani   , but can be distinguished by the shape of the ventral process on the tegular apophysis. In H. storri   the ventral process lacks the flange found in H. brennani   ( Fig. 5C, D View Figure 5 vs. 5G) and is located closer to the apical tip.

Description: Male: Based on male from type locality, WAM T53406 View Materials , Yellowdine, 31°51′S, 119°39′E, WA. Dorsal shield of prosoma orange-brown, darker in eye quadrangle, covered with white setae. Sternum and labium brown with scattered black setae. Chelicerae dark brown with white setae. Legs all greyish-brown, except for paler ventral femur. Projections on apical end of coxae I (see remarks). Opisthosoma all greyblack with black setae except for creamish-yellow streak running from spinnerets two-thirds along either side. Terminal apophysis of pedipalp large, strongly curved apically ( Fig. 23A View Figure 23 ). Pars pendula transparent and connected just below embolus tip ( Fig. 23B View Figure 23 ). Subterminal apophysis large and easily visible next to terminal apophysis. Tegular apophysis with angular ventral process located centrally or near apex. Curved ridge connecting ventral process and apical point ( Fig. 5G View Figure 5 ).

Female: Based on WAM 68/503, Wubin, 30°07′S, 116°38′E, WA. Dorsal shield of prosoma orange-brown with cover of white setae. Sternum, labium, and chelicerae as male. Legs; femur, metatarsus, and tarsus yellowish-cream with tibia and patella black ( Fig. 1D View Figure 1 ). Small projections on apical end of coxae I (see remarks). Opisthosoma black, with pale side streak as male. Epigyne with small anterior pockets, much greater in width than posterior transverse part ( Fig. 23C View Figure 23 ). Internal epigyne with strongly sclerotized anterior pockets and head of spermatheca elongate ( Fig. 23D View Figure 23 ).

Variation: In some males a small black longitudinal stripe is present at the anterior end of the dorsal abdomen. The length of the ridge between the ventral process and apical point of the tegular apophysis can vary ( Fig. 5G View Figure 5 vs. 5H). Some females have a faint pale longitudinal stripe at the anterior end of the dorsal abdomen.

Remarks: The epigynum of the holotype is missing and so a representative female is used here for redescription. Several of the male specimens, including those from the type locality, were found to have prominent protuberances extending from the tip of coxae I and II near the sternum. Following further examination, some females were found to have similar, but reduced, bulges. No other morphological differences were found between those with and without coxal points and as the distributions overlap we currently consider them conspecific.

♂ (♀) (range, mean ± SD): TL, 12.9–20.1, 17.2 ± 1.6; PL, 7.1–10.3, 9.4 ± 0.6; PW, 6.4–8.1, 7.2 ± 0.4; N = 35 (TL, 17.9–23.0, 19.9 ± 1.7; PL, 8.7– 10.3, 9.6 ± 0.5; PW, 6.6–8.1, 7.3 ± 0.5; N = 14).

Natural history: Hoggicosa storri   have been collected from clay, gritty loam, rocky, red, and yellow soils. Specimens have been recorded in association with vegetation of Mallee ( Eucalyptus   ) and Mulga ( Acacia aneura   ) and woodlands of Wandoo ( Eucalyptus wandoo   ), Salmon Gum ( E. salmonophloia   ), York Gum ( E. loxophleba   ), Gimlet ( E. salubris   ), and E. striaticalyx   , as well as open shrubland. Adult females have been collected all year round, whereas adult males have been predominately collected from October to March. Hoggicosa storri   excavates burrows without doors.

Distribution: Western Australia ( Fig. 25 View Figure 25 ).

HOGGICOSA WOLODYMYRI   SP. NOV. ( FIGS 4H, I View Figure 4 , 5F View Figure 5 , 7D View Figure 7 , 24A–D View Figure 24 , 25 View Figure 25 )

Types: Holotype. ♂ from South Australia: Taylorville Station , 34°06′S, 139°58′E, 2–4.x.1999, Strathalbyn Field Nats. ( SAM NN16408 View Materials ). GoogleMaps  

Paratype. ♀ with same data as holotype. ( SAM NN16409 View Materials ) GoogleMaps   .

Other material examined: One-hundred and twentythree males, 27 females, and four juveniles from 87 records (Appendix S1).

Etymology: The specific epithet is a patronym in honour of the senior author’s late grandfather Wolodymyr Kowal, who after immigrating to Australia fell in love with the outback landscapes where this species is found.

Diagnosis: Hoggicosa wolodymyri   can be distinguished from all other Hoggicosa   by its small body size and orange-yellow colour. The male palp is most similar to that of H. bicolor   , but can be distinguished by the tegular apophysis, which has a ridge between the ventral process and the tip much longer than that of H. bicolor   (compare Fig. 5F View Figure 5 vs. 6A). The female epigyne is similar in shape to H. bicolor   but is smaller in size and females can be easily distinguished on body colour.

Description: Male: Based on holotype. Dorsal shield of prosoma orange-brown, darker in eye quadrangle, with faint radial pattern; covered with black setae. Sternum orange-yellow, labium dark orange-brown, both with scattered black setae. Chelicerae dark brown with white setae. Legs orange-yellow. Opisthosoma dorsally orange-yellow with mottled black and grey patches; grey-black setae. Dark orange median longitudinal band at anterior end ( Fig. 4H View Figure 4 ). Opisthosoma laterally and ventrally pale orange-yellow, some black dots on venter. Terminal apophysis of pedipalp large and strongly curved apically ( Fig. 24A, B View Figure 24 ). Pars pendula transparent and joins embolus at embolus tip ( Figs 7D View Figure 7 , 24B View Figure 24 ). Subterminal apophysis present, but located under terminal apophysis and difficult to see ( Fig. 7D View Figure 7 ). Tegular apophysis with small process, pointed ventrally and located away from apical point. Straight ridge between ventral process and apical point ( Fig. 5F View Figure 5 ).

Female: Based on paratype. Dorsal shield of prosoma pale orange, darker in eye quadrangle, with faint radial pattern; covered with black setae. Sternum, labium, chelicerae, and legs as male. Opisthosoma dorsally and laterally as male ( Fig. 4I View Figure 4 ). Venter without black patches. Epigyne with small and simple anterior pockets, only slightly greater in width than posterior transverse part ( Fig. 24C View Figure 24 ). Internal epigyne with thin sclerotized channels of median septum clearly visible as well as thin and elongate spermatheca stalks ( Fig. 24D View Figure 24 ).

Variation: Male specimens from WA are slightly smaller and pale yellow in colour, with less colouration (dark patches) on the abdomen. Some males lack black patches on the ventral opisthosoma.

♂ (♀) (range, mean ± SD): TL, 11.6–14.8, 13.3 ± 1.0; PL, 6.4–7.8, 6.9 ± 0.4; PW, 5.0–6.0, 5.5 ± 0.3; N = 14 (TL, 14.4–16.9, 15.5 ± 1.0; PL, 6.9– 8.5, 7.4 ± 0.7; PW, 5.3–6.4, 5.8 ± 0.5; N = 6).

Natural history: Specimens have been collected from sand dunes, sand plains, interdune swales, and clayey soils associated with open Mallee ( Eucalyptus   ) with mixed understorey or Mulga ( Acacia aneura   ) and Spinifex ( Triodia   ) vegetation. Males and females have been collected predominately from September to December, although a couple of males have been found in March and June. Records indicate H. wolodymyri   constructs a doorless burrow.

Distribution: New South Wales, Northern Territory, South Australia, and Western Australia ( Fig. 25 View Figure 25 ).
