Distribution. Specimens collected from vine scrub in the Taroom district, southeast Queensland, across to the east coast near Bundaberg, Queensland.

Etymology. The species is named after the location of the holotype, Mt. Rose.

Diagnosis. Male: Tegmina and hind wings fully developed (®gures 9, 10). Seventh abdominal tergum specialized, with dense fan shaped cluster of dark brown setae in anteromedial region (®gure 11). Dorsal surface of styles with 2±4 large spines (®gure 13). Distal end of cleft sclerite of right phallomere with 3±4 rows of dark spines (®gure 13).

Description. Male: Dark brown. Pronotum parabolic, widest near base (as in ®gure 4). Base of eyes extending below antennal sockets. Antennae as long as body. Tegmina fully developed, reaching end or just beyond end of abdomen (®gure 9). Hind wings fully developed, reaching top of T7, cubitus vein with 2±3 complete and 1±2 incomplete branches (®gure 10). Front femur Type A3. Pulvilli present on all tarsomeres, 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 (®gure 11). Supraanal plate transverse, hind margin slightly concave (®gure 12). Right paraproct with long thin spines above a slender claw shaped process, and shorter, thick spines below process (®gure 12). Left paraproct keel shaped, with numerous short thin spines (®gure 12). Subgenital plate and styles symmetrical, base of styles curved inward and lined with numerous short thick dark brown spines, plus 2±4 large spines on dorsal surface of styles (®gure 13). Distal end of cleft sclerite of right phallomere with 3±4 rows of dark spines tapering from long, to short at distal end (®gure 13). Holotype ®rst, then paratypes. BL: 13.2, 14.0±16.0; PL: 4.1, 3.8±4.1; PW: 5.3, 5.0±6.1; EL: 1.6, 1.5±1.6; EW: 0.8, 0.8±0.9; TL: 10.7, 10.1±12.5; TW: 4.0, 3.8±4.6.

Female: Often larger than male. Eyes reduced, level with base of antennal sockets. Tegmina reduced, slightly shorter than abdomen. Hindwings vestigial, reaching bottom T3. Supraanal plate rounded, tongue shaped. Subgenital plate broad, smoothly rounded. BL: 12.5±18.7; PL: 3.6±4.5; PW: 4.7±6.2; EL: 1.3±1.6; EW: 0.7±0.9; TL: 6.8±9.4; TW: 3.4±4.7.

Remarks. P. rosensis is very similar to P. weinsteini (see below), and demonstrates sexual wing dimorphism as in P. weinsteini , with males having longer tegmina. However P. rosensis males have fully developed tegmina and hind wings. Comparison of tegmen venation between individuals collected from the same site (Mt. Rose) indicated variation in the rami branching pattern at the terminal end of the radius.
