Material examined. HOLOTYPE male QMT62749, Rope Ladder Cave (FR-2), Fanning River , 19ss45¾S, 146ss30¾E, northern Queensland, hand collected, 18 May 1995, D. P. Slaney and E. Volschenk, in QM . Paratypes: three males (one with

dissected genitalia and right tegmen slide), four females, six ooÈthecae, same data as holotype, in QM ; two males (one with dissected genitalia), two females, two ooÈthecae, Bat Cave (FR-4), same area, hand collected, 15 April 1994, P. Weinstein, in ANIC. Distribution. Found in limestone caves of the Fanning River Karst region, known only from type locality .

Etymology. The species is dedicated to Dr Phil Weinstein of the Wellington School of Medicine, New Zealand, who ®rst recorded and studied the behaviour of cockroaches from Fanning River.

Diagnosis. Male: Seventh abdominal tergum specialized, with dense fan shaped cluster of dark brown setae in anteromedial region (as in ®gure 11). Dorsal surface of styles with 5±7 large spines (®gure 16). Cleft sclerite of right phallomere elongate, with 1±2 rows of spines (®gure 16).

Description. Male: Reddish-brown. Pronotum parabolic, widest near base (as in ®gure 4). Eyes reduced, base of eyes level with base of antennal sockets. Antennae slightly longer than body. Tegmina reduced, reaching top of T6 or T7 (®gure 14). Hind wings vestigial, reaching bottom of T1. Front femur Type A. Pulvilli reduced, 3

more pronounced on last tarsomere, arolia small. First abdominal tergum with fan shaped group of setae on anteromedial region, partly covered by hind margin of metanotum, and numerous setae along anterior border (as in ®gure 6). Seventh abdominal tergum specialized, anteromedial region with dense fan shaped cluster of dark brown setae within a shallow depression (as in ®gure 11). Supraanal plate transverse, hind margin slightly concave (®gure 15). Right paraproct divided into a lobe covered in long thin spines above a claw shaped process, and short thick spines below (®gure 15). Left paraproct keel shaped, with numerous thin spines (®gure 15). Subgenital plate and styles symmetrical, base of styles curved inward and lined with numerous short thick dark brown spines, plus group of 5±7 spines covering dorsal surface of styles (®gure 16). Cleft sclerite of right phallomere elongate, with 1±2 rows of spines tapering from long, to short at distal end (®gure 16). Holotype ®rst, then paratypes. BL: 15.8, 15.9±17.7; PL: 4.3, 3.8±4.5; PW: 5.9, 5.4±6.2; EL: 1.4, 1.4±1.5; EW: 0.7, 0.7±0.8; AL: 19.5, 15.5±17.5; TL: 10.3, 9.0±10.7; TW 4.2, 3.5±4.8.

Female: Larger than male. Eyes reduced, level with base of antennal sockets. Tegmina reduced, reaching T2, hindwings vestigial. Supraanal plate rounded with hind margin slightly concave. Subgenital plate broad, smoothly rounded. OoÈtheca reddish-brown, 4.0±6.0 mm long, with 16 ± 19 egg cells (®gure 17). BL: 16.0 ±21.1; PL: 3.8±5.0; PW: 5.5±6.8; EL: 1.4±1.5; EW: 0.7±0.8; TL: 4.8±5.7; TW: 6.8±7.5.

Remarks. P. weinsteini is very similar to P. rosensis , and they are probably sister species. The shapes of the supraanal plates and paraprocts are similar, however, in P. weinsteini the claw shaped process of the right paraproct is 2±3 times wider and covered in ®ne spines. In addition, in P. weinsteini the cleft sclerite of the right phallomere is elongate, with fewer rows of spines. Both species demonstrate sexual wing dimorphism, although this is more pronounced in P. weinsteini , with males having tegmina nearly twice as long as females ( Slaney and Weinstein, 1997). As with P. rosensis , comparison of tegmen venation between individuals collected from the same site (Rope Ladder Cave) indicated variation in the rami branching pattern at the terminal end of the radius. Specimens of P. weinsteini were collected from caves occupied by the Little Bent-wing bat, Miniopterus australis , and Eastern Horseshoe bat, Rhinolophus megaphyllus .
