Etymology
The specific name is an adjective in apposition derived from muratus (Latin—surrounded by a wall) and refers to the turret-building behaviour of this species and all other species within the genus Dingosa .
Diagnosis
Dingosa murata is most similar to D. humphreysi . Males differ in the shape of the apical tip of the tegular apophysis, which is curved ventrally in D. humphreysi and more or less straight in D. murata . Females of both species are distinguished by the shape of the lateral tips of the inverted T-shaped median septum, which are truncated in D. murata , but reach under the anterior pockets of the epigyne in D. humphreysi .
Description
Male. Based on WAM T51303.
Prosoma, dorsal shield ( Figure 1E View Figure 1 ): dark brown; indistinct dark brown radial pattern; light brown median band widening anteriorly and with two irregular short bands in anterior half; dark brown around fovea; narrow central line of white setae between eyes from behind PLE to clypeus; distinct light brown submarginal bands; narrow dark brown marginal bands; black and interspersed white setae, white setae in median and submarginal bands; few brown macrosetae around eyes and behind PLE; four bristles below AE, one long bristle between AME.
Sternum: shiny brown; white setae which are denser marginally.
Labium: longer than wide; basally dark brown, otherwise brown; front end truncated.
Chelicerae: dark brown, light brown longitudinal band frontally; few white setae basally, otherwise few black setae.
Pedipalps ( Figure 5A, B View Figure 5 ): terminal apophysis apically broad, with two tips, embolus thin, with bent tip; tegular apophysis with basal tooth and its tip more or less straight ( Figure 5B View Figure 5 ).
Opisthosoma ( Figure 1E View Figure 1 ): light brownish grey through a dense cover of silvery and white setae; dark brown cardiac mark with two minor lateral serrations, accentuated laterally by dark setae; yellow-brown bands lateral of cardiac mark; yellow-brown irregular spots in posterior half. Venter brown; covered with brown setae. Spinnerets light brown.
Legs: leg formula VI.I.II.III; dark brown with irregular light patches. Spination of leg I: femur: three dorsal, two apicoprolateral, one retrolateral; patella: one prolateral, one retrolateral; tibia: one dorsal in apical half, three ventral pairs, two prolateral (three on right leg), two retrolateral; metatarsus: three ventral pairs, two prolateral, one retrolateral, one apicoventral, one apicoprolateral, one apicoretrolateral.
Female. Based on WAM 71/1428.
Prosoma, dorsal shield ( Figure 1F View Figure 1 ): as male, marginal dark bands wider and more distinct.
Sternum, chelicerae, and labium: as male.
Opisthosoma ( Figure 1F View Figure 1 ): as male, but overall lighter and with less contrast. Venter as male, slightly lighter. Spinnerets as male.
Epigyne, ventral view ( Figure 5C View Figure 5 ): lateral edges of median septum truncated anteriorly.
Epigyne, dorsal view ( Figure 5D View Figure 5 ): heads of spermathecae with distinct anterior tips; stalks of spermathecae S-shaped.
Legs: leg formula IV.I.II.III; dark brown with irregular light patches; weak scopulate setae on metatarsi and tarsi of leg I. Spination of leg I: femur: three dorsal, two apicoprolateral, two retrolateral; patella: one prolateral, one retrolateral; tibia: three ventral pairs, two prolateral; metatarsus: three ventral pairs, one apicoventral; one prolateral; one apicoprolateral.

Variation. Males (females) (range, mean¡SD): TL 6.88–12.75, 8.41¡1.61; PL 3.63– 6.00, 4.34¡0.72; PW 2.63–4.25, 3.16¡0.51; n 516 (TL 7.63–12.75, 10.68¡1.56; PL 3.88–5.75, 4.89¡0.66; PW 2.88–4.13, 3.51¡0.45; n 510).
Life history and habitat preferences
Adult spiders have mainly been found between April and November with a peak in May, which suggests reproductive activity in autumn. Only one female with eggsac has been collected, without exact locality data and date ( WAM T 53903) .
The only habitat description available for this species is ‘‘sand plain’’ (WAM 71/1433), agreeing with habitat preferences of other Dingosa species.
Distribution
Disjunctive records from Western Australia, and western Victoria and southern New South Wales ( Figure 7 View Figure 7 ).
