Diagnosis Tetralycosa orariais very similar to T. orariola sp. nov.In particular the female genitalia are indistinguishable and separating both species is easiest by the colouration of the carapace. The lateral light bands of T. orariaare wide, although sometimes irregular, and run straight along the carapace margin. In contrast, the light bands in T. orariola sp. nov.are narrow and separated from the carapace margins by narrow dark bands. T. orariais overall larger than T. orariola sp. nov., but sizes overlap. The wide and light marginal bands of the carapace are similar to those of T. wundurra comb.nov., however, both species differ in their genital morphology. The embolus of the male pedipalp in T. wundurra comb. nov.is very broad narrowing abruptly at more than three quarters length into a slim tip, whereas it is of similar width along its whole length and twisted apically in T. oraria. The median septum of the epigyne of T. orariahas a distinct bridge with parallel borders, which is not present in T. wundurra comb. nov.

Description MEASUREMENTS. ♂WAM T53697 ( ♀WAM T53393): TL 8.25 (12.30), CL 4.50 (5.10), CW 3.45 (4.13). Eyes: AME 0.21 (0.21), ALE 0.17 (0.18), PME 0.38 (0.41), PLE 0.33 (0.37). Row of eyes: AE 0.93 (1.05), PME 0.93 (1.05), PLE 1.23 (1.54). Sternum length/width: 1.95/1.65 (2.25/1.88). Labium length/ width: 0.58/0.60 (0.72/0.79). AL 2.85 (6.75), AW 4.2 (5.1). Legs: Lengths of segments (femur + patella/ tibia + metatarsus + tarsus = total length): Pedipalp 1.95+1.65+ – +1.25 = 4.85, I 3.60+4.50+3.30+1.80 = 13.20, II 3.75+4.65+3.75+2.25 = 14.4, III 3.38+3.83+3.60+1.65 = 12.46, IV 4.20+4.95+4.65+1.95 = 15.75 (Pedipalp 2.25+2.10+ – +1.35= 5.70, I 3.60+4.35+2.70+1.65 = 12.30, II 3.60+4.20+2.85+1.65 = 12.30, III 3.45+3.90+3.30+1.58 = 12.23, IV 4.50+5.10+4.35+1.95 = 19.90). VARIATION. ♂( ♀) (range, mean ± SD): TL 6.75–9.45, 8.35 ± 0.82; CL 3.75–4.95, 4.55 ± 0.39; CW 2.85– 4.05, 3.55 ± 0.46; n = 9 (TL 9.75–14.25, 11.26 ± 1.35; CL 4.05–6.45, 5.04 ± 0.77; CW 3.15– 5.03, 3.98 ± 0.64; n = 13). Tetralycosa orariais very variable in colouration. Some specimens are extremely light without a distinct colour pattern; others are dark olive-grey with light bands ( Fig. 1E–F). It appears that the particular microhabitat (for example dark seaweed vs plain beach) may explain the colour patterns of individual specimens (see also McKay 1979b). There also appears to be some intraspecific morphological variation in leg length and eye position, as McKay (1979b)reported a different leg formula (IV>I>II>III) and relative length of the anterior row of eyes and posterior median eyes. Male(based on WAM T53397) CARAPACE ( Fig. 5A). Dorsal line straight in lateral view ( Fig. 6A); brown with indistinct and irregular light colouration medially and broad, irregular light marginal bands; indistinct darker radial pattern; covered with mainly brown setae, but white setae in marginal bands; very few brown bristles in eye region mainly between PME; four long bristles below AE; one long bristle between AME. EYES ( Fig. 6B). Row of AE as wide as row of PME; row of AE slightly procurved ( Fig. 6B). CHELICERAE. Brown, darker apically; covered with long white setae and few brown bristles medially; three promarginal teeth with the median largest; three retromarginal teeth of similar size. STERNUM ( Fig. 5B). Yellow-brown, with dark pigmentation towards the margins; covered with few white setae and longer brown macrosetae that are longer towards margins. LABIUM. Brown, basally dark brown; front end truncate and white. PEDIPALPS ( Fig. 6C–E). Tegular apophysis broad with a basally pointing tip ( Fig. 6C); terminal apophysis forms sheath for the resting embolus; embolus long and thin with curved tip ( Fig. 6E). ABDOMEN. Dorsally dark olive-brown with light lanceolate heart mark in anterior half; few irregular light patches formed by fields of lighter setae; otherwise covered in brown setae ( Fig. 5A). Ventrally yellowbrown with some mottled olive-grey discolouration and with white and fewer brown setae. Spinnerets yellow-brown ( Fig. 5B). LEGS. Leg formula IV>II>I>III. Femora yellow, distal segments darker; weak scopula on tarsus I. Spination of leg I: femur: three dorsal, one apicoprolateral; patella: one prolateral; tibia: three ventral pairs, two prolateral, two retrolateral; metatarsus: three ventral pairs, two prolateral, two retrolateral, one apicoventral, one apicoprolateral. Female(based on WAM T53393) CARAPACE ( Fig. 5C). Brown, indistinct narrow light median band and wide marginal bands; covered with white setae and few black setae anteriorly of fovea; brown bristles in and around eye region; four long bristles below AME, one long bristle between AME. EYES. Row of AE as wide as row of PME; row of AE slightly procurved. CHELICERAE. Colour, setae and dentition as male. STERNUM ( Fig. 5D). Yellow-brown and somewhat darker marginally; setae as male. LABIUM. As male. ABDOMEN. Dorsally yellow-brown with indistinct light lanceolate heart mark; setae as male but with grey setae on dark patches ( Fig. 5C). Venter and spinnerets yellow-brown with little darker pigmentation ( Fig. 5D). EPIGYNE. Ventral view ( Fig. 6F): ovoid median septum with curved posterior border. Dorsal view ( Fig. 6G): small spermathecal heads, convoluted spermathecal stalks attach posteriorly. LEGS. Leg formula IV>I=II>III. Colour pattern as male. Spination of leg I: femur: two dorsal, one apicoprolateral; tibia: three ventral pairs, two prolateral (only one on left leg); metatarsus: three ventral pairs, two prolateral; one retrolateral (only on left leg), one apicoventral.
Remarks An adult male syntypeof Lycosa meraculawas only recently discovered in the MHNP resulting in reevaluation of the juvenile type material of this species that was examined by McKay (1979a)( Framenau et al.2006). The species illustrated as L. meraculaby McKay ( McKay 1979a) is not conspecific with the male syntypeof L. meraculafrom Albany. The material included two closely related coastal species in the genus Costacosa( Framenau & Leung 2013). To fix the taxonomic concept of T. meracula, the male from Albany (MHNP 24364) is here designated as lectotype. Life history and habitat preferences Tetralycosa orariais an exclusively coastal species inhabiting sandy beaches and the base of sand dunes on the foreshore. Adult spiders of T. orariacan be found all year round and do not seem to have a clear seasonal pattern for reproduction, as females with egg sacs and spiderlings have been found from December to February, but also in July and October.
Distribution Coastal mainland Australiasouth of approximately 25°Slatitude, and Tasmania, although a few records are from further inland, if saline wetlands are found near the beach ( Fig. 9).
