Material examined. All Australia. Holotype, male (6.3 mm) ( QM W9805 ), Calliope River mouth, Gladstone, Queensland, 23°50′S, 151°15′E, Van Veen grab, coll. P. Saenger & J. Moverley, between 1975 and 1980. GoogleMaps
Paratypes. 1 male (7.5 mm [dissected and illustrated]), 1 female (7.9 mm [dissected and illustrated]), same data as holotype. Unexamined paratypes GoogleMaps : 35 males and females (QM W9806); also QM W9808 and W9809 .
Supplementary description. Body 2.5 times as long as greatest width, dorsal surfaces punctate, widest at pereonite 5, lateral margins subparallel. Rostral point absent. Eyes ( Fig. 17A View Fig ) separated by about 85% width of head, eye colour black. Pereonite 1 and coxae 2–3 each with posteroventral angle rounded; coxae 5–7 with entire oblique carina; posterior margins of pereonites 7 with irregular submarginal nodules. Pleon with pleonite 1 largely concealed by pereonite 7; pleonites 3–5 posterior margin with regular small nodules; posterolateral angles of pleonite 2 forming acute point, extending posteriorly to anterior of pleonite 3; pleonite 3 without median tubercle and 9 sublateral tubercles on each side, posterolateral margins not extending to posterior margin of pleonite 5, acute; pleonite 4 with 1 median tubercle and 10 sublateral tubercles on each side, posterolateral margin of pleonite 4 rounded, clearly extending beyond posterior margin of pleonite 5; pleonite 5 with 1 median tubercle and 5 sublateral tubercles on each side and posterolateral angles overlapped by lateral margins of pleonite 4. Pleotelson ( Fig. 17F, 17G View Fig ) 0.7 times as long as anterior width; with 2 submedian tubercle rows on dorsal surface (1 tubercle each); lateral margins straight, margins smooth, posterior margin truncate, without median point, with 6 robust setae.
Frontal lamina ( Fig. 17B View Fig ) pentagonal, 2.3 longer than greatest width, lateral margins straight, diverging slightly towards anterior, anterior margin acute, forming median point.
Pereopod 1 ( Fig. 18A View Fig ) basis 2.5 times as long as greatest width, superior distal angle without cluster of acute setae, inferior distal angle with cluster of 2 acute setae; ischium 0.6 times as long as basis, inferior margin without seta, inferior distal margin with 2 RS, superior distal margin with 2 RS; merus inferior margin with 6 molariform RS, set as 2 and 4, with 1 simple seta, inferior distal margin without RS, superior distal angle with 3 RS; carpus inferior margin with 1 RS and 1 simple seta; propodus 2.5 times as long as wide, inferior margin with 2 RS, inferior distal margin with 1 large RS and 1 simple seta, superior distal with 3 simple setae; dactylus 0.7 as long as propodus. Pereopod 7 ( Fig. 18B View Fig ) basis 1.8 times as long as greatest width, superior margin convex, inferior margin without palmate seta; ischium 0.6 as long as basis, inferior margin with 2 RS (set in group of 3 and 3), inferior distal angle with 4 RS, superior distal angle with 5 RS (1 biserrate); merus 0.8 as long as ischium, 1.9 times as long as wide, inferior margin with 2 RS, superior distal angle with 8 RS (5 biserrate), inferior distal angle with 6 RS; carpus as long as ischium, 0.7 times as long as wide, inferior margin with 2 RS, superior distal angle with 10 RS (7 biserrate), inferior distal angle with 9 RS (4 biserrate); propodus as long as ischium, 4.3 times as long as wide, inferior margin with 2 clusters of RS (set as 1 and 2), superior distal angle with 3 slender setae, 1 plumose seta and 1 RS, inferior distal angle with 2 RS; dactylus 0.6 as long as propodus.
Penes ( Fig. 17C View Fig ) opening flush, penial openings separated by 7.0% of sternal width.
Pleopod 1 ( Fig. 17D View Fig ) exopod 1.6 times as long as wide, lateral margin straight, distally narrowly rounded, mesial margin weakly convex, with PMS from distal onethird, with ~35 PMS; endopod 2.3 times as long as wide, distally narrowly rounded, lateral margin strongly concave, with PMS from distal onethird, mesial margin with PMS on distal margin only, endopod with ~17 PMS; peduncle 1.6 times as wide as long. Pleopod 2 ( Fig. 17E View Fig ) exopod with ~46 PMS, endopod with ~17 PMS; appendix masculina with parallel margins, 1.1 times as long as endopod, distally acute. Pleopods 2–5 peduncle distolateral margin with prominent acute RS, 3–5 endopods with distomesial serrate scales.
Uropod ( Fig. 18C, 18D View Fig ) peduncle ventrolateral margin with 2 RS, lateral margin with medial short acute RS, posterior lobe about as long as endopod; rami extending beyond pleotelson, marginal setae in single tier, apices not bifid. Endopod apically not bifid; lateral margin proximally convex, distally straight, proximal lateral margin without RS; distal lateral margin with 1 RS, mesial margin straight and weakly convex, with 7 RS. Exopod extending to end of endopod, 3.3 times as long as greatest width, apically not bifid; lateral margin straight, with 3 sparse RS; mesial margin convex, with 3 RS.
Female. The uropodal exopod is lacking the setal fringe on the posterior lateral margin, otherwise similar of male.
Remarks. Cirolana curtensis is most similar to C. fasfes , new species, in having a similarly shaped uropod, pattern of nodules on dorsal of pleotelson (with female of C. fasfes ), the presence of the wavy nodules on pleotelson margin. See the remarks on Cirolana fasfes for the differences. In the original description the holotype was stated to be as female whereas it is actually male, and the size is 6.3 mm (not 7.3 mm).
Distribution. Only known from the Calliope River, Gladstone, Queensland.
