Figs. 8–9 View FIGURE 8 View FIGURE 9

Material examined. Holotype, male, Queensland, small lake S of Biggenden, along road Biggenden-Maryborough , 25°33.583 S 152°07.345 E, 1-xi-2005, dissected and slide mounted ( QM) GoogleMaps . Paratypes: same data as the holotype, 0/1/0 dissected and slide mounted ( QM), 7/10/2 (in fluid, RMNH) GoogleMaps .

Diagnosis. III-leg-2 with a very long, heavy ventral seta, located nearly in the centre of the segment, distally slightly expanded, nearly truncated tip; the three specialized setae of IV-leg-5 slender, hair-like, placed close together and located on slight ventral bulge.

Description. Male. Dorsal and ventral shield present; dorsal shield 606 long and 475 wide, with four pairs of glandularia ( Figure 8B View FIGURE 8 ), fused posteriorly with ventral shield. Postocularia fused with the ventral shield; no glandularia lying in the dorsal furrow. Dorsal shield without a peculiar coloration. Ventral shield 637 long and 569 wide, tips of first coxal plates rounded. Apodemes of anterior coxal plates extending beyond the middle of third coxal plates. Genital plates fused with the ventral shield with approximately 23-24 pairs of acetabula, 256 wide between outer margins of genital acetabula; gonopore long. Excretory pore subterminal. Ejaculatory complex 117 long.

Palp as illustrated in Figure 8F View FIGURE 8 : dorsal length/height: P1, 31/39; P2, 113/61; P3, 53/45; P4, 108/33; P5, 30/17; dorsal heavy seta at the tip of P5 widely diverging the more ventral two. Gnathosoma with anchoral process 145 long. Chelicera 141 long, claw 52 long, basal segment 107 long

Dorsal lengths of I-leg-2–6: 115, 113, 163, 178, 158; dorsal lengths of III-leg: 80, 109, 100, 159, 186, 159; IIIleg-2 with a very long, heavy ventral seta, located nearly in the centre of the segment, distally slightly expanded, nearly truncated tip ( Figure 9B View FIGURE 9 , inset); III-leg-5 with a long, heavy distoventral seta with large pectinations, heavy setae longer ( Figure 9B View FIGURE 9 ); dorsal lengths of IV-leg: 91, 116, 119, 153, 281, 206; IV-L-5 bowed; the three specialized setae of IV-leg-5 slender, a hair-like, placed close together and located on slight ventral bulge ( Figure 9 View FIGURE 9 C-D). IIIleg-3 with one, III-leg-4 and 5 each with three swimming setae; IV-leg-3 with one distoventral, IV -leg-4 and 5 each with three distoventral swimming setae.

Female. Dorsal shield 656 long and 494 wide, with three pairs of glandularia ( Figure 8D View FIGURE 8 ). Ventral shield 763 long and 731 wide. Genital plates with approximately 22-29 pairs of acetabula, 319 wide between outer margins of acetabula; gonopore 156 long.

Palp: dorsal length/height: P1, 31/38; P2, 108/66; P3, 58/52; P4, 106/38; P5, 31/19. Gnathosoma with anchoral process 166 long. Chelicera 165 long, claw 50 long, basal segment 102 long. Dorsal lengths of III-leg: 72, 106, 93, 150, 166, 159; dorsal lengths of IV-leg: 84, 123, 126, 184, 228, 200; swimming setae setation as in male.

Etymology. Named for the untoothed seta of III-leg-2.

Remarks. The new species resembles Recifella triradiata , but clearly differs in III-leg-2 with a large strange, truncated seta which is absent in triradiata . Moreover, the three specialized setae in the new species are much more slender, hair-like (these setae in triradiata are somewhat widened distally, compare figure 942 in Cook 1986 with figures 9C-D). Recifella tinka resembles the new species in having three specialized setae on IV-leg-5 not widened distally, placed close together and located on a slight ventral bulge (see Figure 5B View FIGURE 5 ). From the latter, the new species differs in slender palpal segments and the three specialized setae on IV-leg-5 comparatively more slender, and the most anterior one somewhat more distanced from the two others (compare figures 9C-D and figure 5B)
