Agelina [sic] labyrinthica Rainbow, 1897: 528   , misidentification, noted by Butler (1929).

Corasoides australis Butler, 1929: 42   ; Butler, 1939: 186; Roewer, 1954: 61; Bonnet, 1956: 1203; Platnick, 1997: 609.

Types. Presumed syntype male, in MV, labelled “ Corasoides australis Butler   type male K-108”, and on another pencilwritten label, “ CORASOIDES australis GENOTYPE, G.S.G. BUTLER, Roy. Soc. Vic. 1929   ”. The male shares a vial with a female which is distinguished as “type female K-109”. There is no collection locality or date label and the only labels present would appear not to be original—the whereabouts of original labels is unknown.

Type locality. Two localities and dates are given by Butler (1929) for material examined, Cheltenham, 12 April 1925 and Waddy Point , Victoria   , 10 January 1929. In the same paper he recorded the type locality as Cheltenham but no state was given. It is probable that since he lived near Cheltenham in Victoria   , that this is the type locality intended and not Cheltenham in Queensland   or New South Wales. Further, in the register of the MV records, the locality of the male is given as Cheltenham , Victoria   .

Type status. Butler (1929) described both sexes, stating the type locality as “Cheltenham”. He specifically mentions that he had only one female that was collected in January near Bairnsdale, Victoria. Since Butler did not include Bairnsdale as a type locality, this female cannot strictly be considered a syntype   .

He did not indicate how many males were collected from Cheltenham, nor whether he also collected males from Waddy Point. Subsequently, it cannot be assumed that the existing male is the only specimen from the type locality (Recommendation 73F, ICZN, 1999). Therefore this specimen should be regarded as a syntype. Material examined. Male and female as above and the following:

Diagnosis. Male palpal cymbium with long digitiform portion but less than twice the length of the bulb diameter and often bent almost 90°. Conductor distinctly T-shaped, tip spine-like ( Fig. 9b View Figure 9 ), unlike blunt tip of C. motumae   sp. nov. and lacking flange of C. occidentalis   sp. nov. Female epigyne with no lateral extension of the scape. Insemination ducts highly convoluted and looping over the surface of the spermathecae.

Description. Medium sized spider. Carapace. Type specimen light to reddish tan, head region and chelicerae darker. Little to no pattern, black edging surrounding eyes. Abdominal pattern. Basic dorsum pattern in most material examined ( Figs 2 View Figure 2 , 5a–b View Figure 5 ). In the presumed syntype the pattern is less distinct ( Fig. 2a View Figure 2 ); the central region is almost as dark as the background to the spots and the cream dorsolateral stripes do not have a definite boundary ( Fig. 2a View Figure 2 ). In the female figured by Butler (1929), the basic pattern is darker, the dorsolateral stripes and two pairs of pale spots are very distinct but the rest of the dorsal surface is very dark, obscuring the central stripe ( Fig. 2b View Figure 2 ).

Male. CL 5.8 (4.1–5.3), CW   4.5 (3.3–4.5), abdomen of type misshapen, HW 3.5, EpGW 1.7, MOQ L 0.8, MOQAW 0.6, MOQPW 0.7, SL 3.1, SW   2.8, ML   2.5, MW 1.1, LL 1.3, LW 1.0, ChelL 4.1 (2.6–4.5), ChelW 1.4 (1.2–1.3), clypeus height 0.6. Cephalothorax. Sternum longer than wide, bluntly pointed posteriorly. Labium slightly longer than wide, basally notched. Chelicerae. Robust. cheliceral teeth: v ery variable ( Fig. 8a–j View Figure 8 ), even between left and right of one specimen ( Fig. 8d,f View Figure 8 ). retromarginal 6(3), promarginal 4(3) Transverse ridges between teeth margins. Fangs with serrations. Legs. Leg lengths and spination of the presumed syntype cannot be given because of the separation or absence of all its leg segments. Leg lengths and spination given here are those of KS.71823 from Lakes NP (Victoria). This specimen is a similar size to the presumed syntype. Leg lengths

Ventral apophysis large, curved towards bulb to hold embolus, one side with bulging membranous portion. Retrolateral apophysis long, spine-like, curving initially retrolaterally and then down towards its base. Embolus long, spine-like, originating retrolaterally. Conductor distinctly T-shaped. Conductor tip fine, pointed, mostly straight. Trichobothria on cymbium: single row of 4–5. Abdomen. A tail of small spigots is present on the anterior lateral spinnerets ( Fig. 3b,c View Figure 3 ).

Tarsi were not present on the female specimen illustrated by Butler (1929). Figures in parentheses are for a Victorian female of similar size. Totals in parentheses include these substituted tarsal lengths. Spination. Leg I: femur d1,3,1,2 p1,1; tibia v2,2,2 p1; metatarsus v2,2,2 p1. Leg II: femur d1,2,2,1,2,3; tibia d1,1 v2,1,1,2; metatarsus d1,1 v2,2,2. Leg III: femur d3,3,2,2,3; tibia d1,1 v2,2,2; metatarsus d1,2,2,2, v2,2,2. Leg VI: femur d2,1,1,1,3; tibia v2,2,2; metatarsus d2,2,2,2, v2,2,2. Palp: femur d1,1,1,2; tarsus several. Epigyne. Length 1.0, width 1.6 for specimen figured by Butler (1929). Morphologically variable across range but generally with small genital openings and no lateral extension of the scape ( Figs 7b View Figure 7 , 11a–l View Figure 11 ). Surface smooth (The epigyne has been drawn as highly ridged by Lehtinen, 1967 but this mistaken appearance is caused by the insemination ducts being visible through the surface of the epigyne). Morphology of scape is often difficult to discern. Insemination ducts highly convoluted (5–7 bends), looping over the surface of the spermathecae ( Figs 7d,f View Figure 7 , 12a–h View Figure 12 ). Apparent variability is due to position of loops over spermathecae but loops per se maintain similar pattern. Spermathecae large and close together.

Habitat. Corasoides australis   is found in temperate woodland, dry sclerophyll forest, heathland and semi-arid habitats. A specimen from Cooloola, Queensland, recorded as from rainforest is probably from wet sclerophyll forest. In all habitats it can reach high densities. Populations are often locally clumped and on embankments can be up to five tiered.

Distribution. Eastern Queensland and New South Wales south from Blackdown Tableland, through Victoria, Tasmania and South Australia to Eucla in Western Australia and north west to Shark Bay excluding the coastal margin of WesternAustralia from Dongara to Cape le Grande ( Fig. 7g View Figure 7 ). A single specimen is recorded as being from Black Point, WA. Corasoides australis   is sympatric with C. occidentalis   sp. nov. in some areas, e.g. Toodyay, Collie and probably sites between Greenough and Cervantes.

Remarks. Corasoides australis   is the smallest of the Australian species although there is overlap in size with other species. Corasoides australis   probably reaches its largest size on and near Fraser Island and its smallest size in the arid inland of South Australia and Western Australia. Both adults and juveniles always dig a burrow. The male does not cohabit with the female at any time, nor is the epigyne plugged.

A cline can be distinguished by the angle of the conductor tip ( Fig. 6g View Figure 6 ). On the north east coast of its distribution the tip is long and straight and projected retrolaterally. On the south east coast, the tip curves slightly more towards the base of the cymbium ( Fig. 9b View Figure 9 ). Across the south the tip is bent over at more than 90° ( Fig. 9d View Figure 9 ) but straightens out again in Western Australia ( Fig. 9c View Figure 9 ) and going north so that specimens from the Shark Bay region ( Fig. 9a View Figure 9 ) resemble those from Queensland and the Sydney region. This is shown diagrammatically in Fig. 6g View Figure 6 . What appears now as a double east/west cline could possibly have once been a single north/south cline, which lost most of the intermediate representatives from the central Australian region. This double East/West cline is also apparent in the appearance of the retrolateral apophysis which has a distinct peak on the apex in eastern and western specimens ( Fig. 10a,b View Figure 10 ) but is lacking in the southern specimens ( Fig. 10c,d View Figure 10 )

There is also variation in the appearance of the female epigyne, particularly in the definition of the scape ( Fig. 11a–l View Figure 11 ). However, this variation does not seem to follow any geographical pattern.
