( Figures 18–22 View FIGURE 18 View FIGURE 19 View FIGURE 20 View FIGURE 21 View FIGURE 22 )

Etymology. The species is named after Australia.

Type material: holotype ♂ ( AM P-P.83570) , allotype ♀ ( AM-P.83571) , 14♀, 4♂ & 3 juv. (paratypes, ZMH K42335 View Materials ) from Australia, New South Wales, bore TR14 (B), 93025, 31°18' 13.644” S 151°09' 13.896” E, coll. P. Hancock, 10/02/2006 GoogleMaps

Description. Male (holotype): Carapace subtriangular in lateral view ( Figure 18B, C View FIGURE 18 ), L = 0.42 mm. Dorsal margin highly arched around mid L, then sloping equally towards anterior and posterior end. Greatest H lying around mid L and equaling 64% of L. Both anterior and posterior margins rounded, but posterior being narrower than anterior. Inner calcified margin anteriorly equaling 26%, and posteriorly 19% of L. Marginal pore canals short, straight and denser anteriorly than posteriorly; on RV zone of marginal pore canals slightly enlarged around mouth area. Selvage peripheral anteriorly and not present posteriorly on LV. Ventral margin almost straight on LV, while more concave on RV ( Figures 18C View FIGURE 18 , 19B View FIGURE 19 ). In dorsal view, carapace subovate and with greatest W around middle, equaling 65% of total L; almost evenly rounded. LV overlapping RV on all free margins. RV without marginal tubercles along free margin. Surface of carapace smooth ( Figure 19A View FIGURE 19 ), only covered with relatively dense setae.

A1 ( Figure 20D View FIGURE 20 ): 6-segmented. First segment with anterior-proximally seta transformed into sensory organ (Wouters organ), and one normally developed antero-distally. Same segment with two setae posteriorly. Second segment with one anterior seta, reaching distal margin of fourth segment; same segment with sensory organ (Rome organ) inserted posteriorly. Third segment probably representing fused third and fourth segment and with two medial setae: one anterior and one posterior, as well as four distal setae: two anterior and two posterior; posterior ones being much shorter than anterior ones. Following segment with one posterior seta, exceeding distal end of terminal segment and two anterior, long setae. Penultimate segment with a total of four distal setae, all being very long. Terminal segment with 4 setae as well, most posterior one being transformed into a weak claw, and most anterior one being transformed into aesthetasc ya, which is almost as long as entire A1.

A2 ( Figure 21D View FIGURE 21 ): Exopod consisting of plate, one long and two short setae. First endopodal segment with two ventro-distal setae, both very long, and no swimming setae at all. Penultimate segment subdivided but all “t” setae normally developed. Setae z1 and z3 reaching 1/3 of terminal claws, z3 transformed into claw, which reaching 2/3 of terminal claws. Claws G1 and G3 reduced, latter one shorter than former. Claw G2 very long, much longer than A2 itself. Aesthetasc well developed and long.

Md ( Figure 21B View FIGURE 21 ): First segment on the palp with total of four setae. Second segment externally with one seta, while internally with four long and one short seta. Penultimate segment with four setae extero-laterally, two setae extero-distally, and four setae intero-distally. Terminal segment with three stronger claws and three setae. None of the claws fused with segment. Terminal segment only 1.5 times longer than wide.

Mxl palp ( Figures 19C View FIGURE 19 , 20A View FIGURE 20 ): First segment narrow with four anterior setae. Terminal segment with 3 claws (posterior one more seta-like) and two setae. Terminal segment very slightly elongated (only about 1.5 times longer than wide).

Rake-like organ ( Figure 20E View FIGURE 20 ): With 10–11 teeth.

T1 and Prehensile palps ( Figure 20B, C View FIGURE 20 ): Right palp ( Figure 20B View FIGURE 20 ) slightly more robust than left one ( Figure 20C View FIGURE 20 ), finger of latter palp thinner and more curved. One of setae on right palp cylindrical with enlarged middle part, other setae normal. On protopod two “a” setae present. Exopod consisting of six rays.

T2 ( Figure 22E View FIGURE 22 ): Basal seta present. Setae “e” and “f” reaching distal end of penultimate segment. Seta “e” almost reaching middle of terminal claw. Seta h3 on terminal segment short. Terminal claw poorly serrated and 1.6 times as long as three distal segments combined. T2 covered with long and dense pseudochaetae, setae “e” and “f” and “g” plumose.

T3 ( Figures 19D View FIGURE 19 , 22B View FIGURE 22 ): Basal segment with d2 seta. Setae “e”, “f” and “g” all being well developed. Width of terminal segment almost twice the length, setae h1 and h2 equally long.

UR ( Figure 21A View FIGURE 21 ): L ratios between anterior margin, anterior, and posterior claw equaling 2.7: 1.6: 1. Posterior seta short and inserted quite distally on posterior margin.

Hemipenis ( Figure 22D View FIGURE 22 ): Lobe “a” distally foot-like, lobe “b” wide, but short, lobe “h” fist-like and looking like being movable.

Zenker organ: Consisting of seven whorls of spines.

Female: Carapace same as male ( Figure 18A, D, E View FIGURE 18 )

A2 ( Figure 22A View FIGURE 22 ): Claw G2 as long as all other terminal claws, them being much longer than A2 itself. All zsetae normally developed, and not transformed into claws.

T2 ( Figure 22F View FIGURE 22 ): Seta “g” short.

UR ( Figure 22C View FIGURE 22 ): L ratios of anterior margin, anterior and posterior claw 2: 1.2: 1. Genital field rounded and sclerified around edges, without any extensions.
