Fissarena barrow , new species Figures 531, 532 ; Map 38

TYPE: Female holotype taken in Area RK on Barrow Island, 20 ° 48 ̍ S, 115 ° 26 ̍ E, Western Australia (Feb. 20, 1977), deposited in QMB ( S34532 ).

ETYMOLOGY: The specific name is a noun in apposition taken from the type locality.

DIAGNOSIS: Females resemble those of F. ethabuka in having medially touching epigynal ducts, which divide the spermathecae into anterior and posterior portions, but differ in having a long epigynal atrium (figs. 531, 532).

MALE: Unknown.

FEMALE: Total length 9. Coloration as in F. ethabuka . Leg spination: femora: II r0­1­ 0; III p1­1­0, r0­1­0; IV p0­0­0, r0­0­0; tibiae: I, II v1p­1p­1p; III p0­0­0, v1p­1p­2, r0­ 0­0; IV p0­0­0, v1p­2­2; metatarsi: II v2­0­ 0; III p0­0­0, r0­0­0; IV p0­0­0, v2­1p­1p, r0­0­0. Epigynum with long anterior atrium (fig. 531); epigynal ducts united posteriorly, transverse branch dividing spermathecae (fig. 532).

OTHER MATERIAL EXAMINED: None.

DISTRIBUTION: Known only from Barrow

Island, Western Australia (map 38).

Figures 159 , 501–504 , 506–508 ; Map 39

Rebilus castaneus Simon, 1908: 382 (two juvenile syntypes from Yalgoo, Western Australia, in ZMB, examined).

NOTE: Simon’s description indicates that he did not have adult material of this species from any of the four sites specified. However, the vial of this species in the Simon collection in MNHN, labelled only as ‘‘Austr. occid. (Mich.),’’ includes an adult male. Since this male presumably represents Simon’s concept of the species, it seems best to accept it as the de facto type, and to follow Simon’s use of this name for this species.

DIAGNOSIS: Males can easily be recognized by the two 90 ° turns made by the palpal conductor, along the retrolateral side of the palpal bulb (fig. 502); females resemble those of F. barrow in the shape of the epigynal atrium (which varies significantly in width, as shown in figs. 506–508, although it seems always to be shield­shaped), but have much more highly convoluted epigynal ducts (fig. 504).

MALE: Total length 9. Coloration as in F. ethabuka except carapace light brown posteriorly, dark reddish­brown anteriorly. Leg spination: femora: I r0­1­1; II p1­1­1; IV r0­ 1­2; tibiae IV p1­2­1, r1­2­1; metatarsi: I v2­ 1r­0; III v2­2­1p; IV p1­0­1, v2­2­1p, r2­1­ 1. Retrolateral tibial apophysis situated at about half of segment length, digitiform (fig. 502); conductor making two 90 ° turns along retrolateral side of bulb, resulting in s­shaped structure (fig. 501).

FEMALE: Total length 10. Coloration as in male. Leg spination: femora: I r1­1­1; II p1­ 1­1; metatarsi III, IV p1­0­0. Epigynal atrium shield­shaped but variable in width (figs. 503, 506–508); epigynal ducts extended anteriorly along sides of atrium, not enlarged along posterior edge of epigynum (fig. 504).
