Male (based on WAM T62785)

CARAPACE ( Fig. 10E View Fig ). Dorsal line straight in lateral view; brown with indistinct darker radial pattern; indistinct narrow light median band limited to posterior two thirds and very distinct light lateral bands of one tenth of carapace width extending to margin; covered with brown setae, white setae in marginal band; few dark setae between eyes; brown bristles lateral of PE and between PME and PLE; four long bristles below AE; one long bristle between AME.

EYES. Row of AE slightly wider than row of PME; row of AE very slightly procurved.

CHELICERAE. Light orange-brown; white setae and brown macrosetae; three promarginal teeth with the median largest; three retromarginal teeth of similar size.

STERNUM ( Fig. 10F View Fig ). Yellow-brown with some grey pigmentation; covered with brown setae that are longer and denser towards margins.

LABIUM. Brown; front end truncate and white. PEDIPALPS ( Fig. 12 View Fig A–C). Tegular apophysis broad with a baso-laterally pointing tip ( Fig. 12A View Fig ); embolus broad with short, slim tip ( Figs 2F View Fig , 12C View Fig ).

ABDOMEN. Dorsally olive-grey with lighter brown spots and lines; yellow-brown lanceolate heart mark in anterior half; a pair of two large yellow-brown patches in posterior half; covered with olive-brown setae, light brown or white setae in heart mark and posterior patches ( Fig. 10E View Fig ). Ventrally light yellowbrown with some rudimentary, indistinct olive-grey median discolouration; covered with white setae. Spinnerets yellow-brown ( Fig. 10F View Fig ).

LEGS. Leg formula IV>I>II>III; light yellow-brown; distal half of metatarsi and tarsi of leg I darker; hair-like erect setae in particular on metatarsi of leg I. Spination of leg I: femur: three dorsal, two prolateral, two retrolateral; patella: one prolateral, one retrolateral; tibia: one dorsal, three ventral pairs, two prolateral, two retrolateral; metatarsus: three ventral pairs, two prolateral, two retrolateral, one apicoventral, one apicoprolateral, one apicoretrolateral.

Female (based on WAM T70296)

CARAPACE ( Fig. 10G View Fig ). Light brown with indistinct darker radial pattern; indistinctly lighter medially; distinct lighter lateral bands and indistinct grey marginal bands; covered with brown setae, but white setae in lateral bands; brown bristles around eyes; four long bristles below AME, one long bristle between AME.

EYES. Row of AE wider than row of PME; median line through AE slightly procurved.

CHELICERAE. Very dark reddish-brown, long silverish setae and long brown bristles medially; three promarginal teeth with the median one largest, three retromarginal teeth of similar size.

STERNUM ( Fig. 10H View Fig ). Yellow-brown with some grey pigmentation; brown bristles, denser and longer towards margin.

LABIUM. Dark brown, darker centrally; front end truncate and wide.

ABDOMEN. Irregularly dark olive-grey, indistinct yellow-brown lanceolate heart mark in anterior half; mainly white setae and fewer brown macrosetae ( Fig. 10G View Fig ). Venter yellow-brown; setae as dorsal but less macrosetae. Spinnerets yellow-brown ( Fig. 10H View Fig ).

EPIGYNE. Ventral view ( Fig. 12 View Fig D–E): wider than long, median septum with indistinct inverted T-shaped dark pattern. Dorsal view (WAM T47205; Fig. 12F View Fig ): spermathecal heads distinctly wider than spermathecal stalks that attach posteriorly.

LEGS. Leg formula IV>I=II>III. Light brown, basal third of femora lighter. Spination of leg I: femur: two dorsal, one retrolateral; tibia: one apicoventral pair; metatarsus: three (small) ventral pairs, one apicoventral.


Tetralycosa wundurra comb. nov. was initially described in the lycosine genus Trochosa solely based on the eye pattern, with the row of the anterior eyes being wider than that of the posterior median eyes ( McKay 1979b). However, genital characters clearly identify this species as a member of the genus Tetralycosa with no affinities to the Lycosinae and it is consequently transferred from Trochosa . The male of T. wundurra comb. nov. is here described for the first time.

Life history and habitat preferences

Most specimens where collected in pitfall traps exposed from October to March in samphire vegetation near salt lakes or on the lake floor.
