Recifella kakadu Smit, 2007 Figs. 10–11, 16D Material examined. Northern Territory. 1/0/0, Florence Creek downstream of Florence Falls, Litchfield NP, 13°05.885 S 130°46.999 E, 25-ix-2005, dissected and slide mounted.. Description. Male. Dorsal and ventral shield present; dorsal shield colouration conspicuous reddish, 477 long and 422 wide, with four pairs of glandularia (Figure 10B), fused posteriorly with ventral shield. Postocularia fused with the ventral shield; no glandularia lying in the dorsal furrow. Dorsal shield with a peculiar coloration as illustrated in Figure 16D. Ventral shield 528 long and 475 wide, tips of first coxal plates rounded. Apodemes of anterior coxal plates extending the middle of third coxal plates. Genital plates fused with the ventral shield with approximately 24-25 pairs of acetabula, 280 wide between outer margins of acetabula; gonopore 72 long. Ejaculatory complex 122 long. Palp as illustrated in Figures 10 C-D: dorsal length/height: P1, 24/33; P2, 117/72; P3, 50/50; P4, 84/30; P5, 35/18; dorsal heavy seta at the tip of P5 widely diverging the more ventral two. Gnathosoma ventrally 53 long, 113 with anchoral process. Chelicera 141 long, Dorsal lengths of I-leg: 55, 91, 86, 117, 129, 134; dorsal lengths of III-leg: 61, 102, 83, 127, 136, 133; III-leg-5 with a short distal seta, distally bluntly pointed and without a large pectinations (Figure 11B); dorsal lengths of IV-leg: 66, 128, 109, 153, 194, 166; IV-L-5 not bowed, comparatively short, with four setae, the most anterior one bowed and with large pectinations, the three specialized setae placed in posterior part of the segment, most proximal of them with small pectinations, two other specialized setae with large pectinations (Figure 11 C-D). III-leg-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. Remarks. We give here a redescription of Recifella kakadu Smit, 2007 a species known previously from a single male from Baboalba springs in Northern Territory (Smit 2007). Smit (2007) mentioned the presence of five pectinate setae on IV-leg-5, four so-called specialized setae with small pectinations and the most anterior one bowed and with large pectinations. In the new specimen from Florence Creek, IV-leg-5 possesses three specialized setae, most proximal of them with small pectinations, two other specialized setae with large pectinations, especially the most distal one, which is also larger than the other specialized setae. More material is needed to know the number of specialized setae of IV-leg-5. For the time being, we assign specimens with IV-leg-5 with three or four specialized setae to R. kakadu.
