Type specimen.

Holotype male, Tubrabucca (31°52'S, 151°25'E, New South Wales, Australia), 19 January 1049, RTMP, ANB (MV K-14856).

Other material examined.

6 males, 14 females (1 with egg sac), 1 juvenile (in 15 records) (see Suppl. material 1).

Etymology.

The specific epithet is a noun in apposition and refers to a specific Salsa dancing style, Rueda de Casino, in which changing pairs of dancers from a circle and dance moves are being called out by a single person. It is a noun in apposition.

Diagnosis.

Males of S. rueda sp. nov. are identified from all other species of the genus by the highly elongated median apophysis of the pedipalp and the enlarged basal, curved prong on the terminal apophysis (Figs 3A-C View Figure 3 , 19C View Figure 19 ). Females can be distinguished from all other species by shape of the epigyne base, which is much longer than wide and has a central longitudinal ridge (Fig. 20A View Figure 20 ).

Description.

Male (based on holotype, MV K-14856). Total length 6.1. Carapace 3.3 long, 2.6 wide, brown, slightly paler in cephalic area and posteriorly (Fig. 19A View Figure 19 ). Eye diameter AME 0.16, ALE 0.14, PME 0.09, PLE 0.09; row of eyes: AME 0.47, PME 0.43, PLE 1.37. Chelicerae orange-brown; with four promarginal teeth (basal and apical largest) and three retromarginal teeth (basal largest). Legs shades of brown, femora basally yellow-brown in legs II, III and IV (Fig. 19A, B View Figure 19 ). Leg formula I> II> IV> III; length of segments (femur + patella + tibia + metatarsus + tarsus = total length): I - 4.5 + 1.5 + 2.8 + 2.6 + 1.0 = 12.4, II - 3.0 + 1.4 + 2.0 + 2.4 + 0.9 = 9.7, III - 1.7 + 0.9 + 1.2 + 1.2 + 0.6 = 5.6, IV - 2.6 + 1.1 + 1.8 + 2.2 + 0.8 = 8.5. Labium 0.36 long, 0.56, brown; endites brown (Fig. 19B View Figure 19 ). Sternum 1.5 long, 1.2 wide, dark brown (Fig. 19B View Figure 19 ). Abdomen 2.7 long, 2.6 wide, dorsal folium uniformly olive-grey bordered by broad wavy pale bands (Fig. 19A View Figure 19 ); venter dark olive-grey with two ovoid lateral white patches (Fig. 19B View Figure 19 ). Pedipalp length of segments (femur + patella + tibia + cymbium = total length): 0.6 + 0.2 + 0.1 + 1.1 = 2.0; paracymbium slightly curved with conspicuous base (Figs 3A, B View Figure 3 , 19D View Figure 19 ); median apophysis bearing a rounded basal process, elongated C-shaped; basal arch with numerous tubercles (Figs 3A-D View Figure 3 , 19C View Figure 19 ); conductor lobe broad (Figs 3A-C View Figure 3 , 19C View Figure 19 ); terminal apophysis sub-rectangular with a curved, heavily sclerotised basal prong (Figs 3A-C View Figure 3 , 19C View Figure 19 ); conductor heavily sclerotised, spatulate (Figs 3A-C View Figure 3 , 19C View Figure 19 ); embolus strong and slightly sinuous (Figs 3A-C View Figure 3 , 19C View Figure 19 ).

Female (based on AM KS.50201): Total length 10.5. Carapace 4.2 long, 3.5 wide; reddish brown, slightly paler in cephalic area and posteriorly, covered by white setae specifically in cephalic area (Fig. 20A View Figure 20 ). Eye diameter AME 0.18, ALE 0.16, PME 0.13, PLE 0.11; row of eyes: AME 0.54, PME 0.52, PLE 2.18. Chelicerae reddish brown, four promarginal teeth (apical and second basal largest) and three retromarginal teeth (basal largest). Legs orange-brown (Fig. 20A, B View Figure 20 ). Pedipalp length of segments (femur + patella + tibia + tarsus = total length): 1.1 + 0.4 + 0.7 + 1.3 = 3.5. Leg formula I> II> IV> III; length of segments (femur + patella + tibia + metatarsus + tarsus = total length): I - 4.0 + 1.7 + 3.5 + 3.3 + 1.2 = 13.7, II - 3.7 + 1.6 + 2.8 + 2.9 + 1.1 = 12.1, III - 2.5 + 1.1 + 1.4 + 1.5 + 0.8 = 7.3, IV - 3.5 + 1.6 + 2.2 + 2.6 + 1.0 = 10.9. Labium 0.58 long, 0.86 wide, dark brown; endites dark brown (Fig. 20B View Figure 20 ). Sternum 1.8 long, 1.6 wide, dark reddish brown (Fig. 20B View Figure 20 ). Abdomen 6.0 long, 6.0 wide; dorsum beige with indistinct darker folium pattern (Fig. 20A View Figure 20 ); venter black and laterally with elongate white patches and pale transverse band behind epigastric furrow (Fig. 20B View Figure 20 ). Epigyne much longer than wide; atrium with central elevated section and a transverse ridge anteriorly (Fig. 20C View Figure 20 ); scape shorter than half the length of epigyne base (Fig. 20C, D View Figure 20 ); central division a conspicuous narrow ridge (Fig. 20E View Figure 20 ). Spermathecae rounded and located on the basis of the genitalia, separated by the width of the median ridge (Fig. 5E View Figure 5 ).

Variation.

Total length males 6.0-6.8 (n = 5); females 7.2-10.5 (n = 4). The colour variations in S. rueda sp. nov. are probably the most uniform with the patterns in the folium often little expressed (Figs 19A View Figure 19 , 20A View Figure 20 ). There was no evidence of scape breakage in any of the females examined by us.

Life history and habitat preferences.

Specimens were collected in December and January, with a single female from March, indicating this species to be summer-mature. There was no habitat information on any of the specimen labels.

Distribution.

Salsa rueda sp. nov. were found in the Australian Capital Territory, New South Wales, Victoria, and Tasmania (Fig. 21 View Figure 21 ).
