Description. Egg. ( Fig. 5 View FIGURE 5 J, K) Spherical with many elongated projections. Mean diameter 222 µm, range 202– 235, n =25). About 30 polygons each elongated round a central groove usually infilled so the groove appears double. Walls of polygons narrow and steep, upper edges uneven and drawn into 3–6 elongated projections, mainly at wall junctions of adjacent polygons. Polygon floors sloping inwards to the groove and with uneven surfaces.

Differential diagnosis. This species is distinctive on many criteria. No other Paralimnadia   (or Eulimnadia   ) has an egg with an infilled groove within the polygons. The approximately 30 polygons each with 3–6 elongated projections are also distinctive. There are 20 trunk segments compared to 17–18 in most and 15–16 in some limnadiids. Both male and female heads have non-distinctive rostra and antennae, and the palps of the claspers are of typical construction. However the clasper endite III ( Fig. 9 View FIGURE 9 D, E) is by far the largest of any species of Paralimnadia   ; it protrudes as much as the diameter of the apical knob. The telson ( Fig. 9 View FIGURE 9 C, H) has about 10 posterior row spines irregularly spaced and sized with the last spine particularly enlarged (about 3–5 times the length of the first). The cercopod ( Fig. 9 View FIGURE 9 C, H) is completely devoid of setae, spines and denticles, a condition unknown in any other Paralimnadia   .

Remarks. Unlike other species of Paralimnadia   described over 100 years ago, this species is well characterised and types appointed are stored in the Zoologisches Institut und Zoologisches Museum, Hamburg, (K- 19624) ( Wolf 1911; Richter & Timms 2005). There are also two syntypes in the WAM registered number C390. Only the egg needs to be described.

Distribution and ecology. Paralimnadia badia   occurs throughout the wheatbelt of Western Australia and also beyond, into the goldfields and eastern Nullarbor ( Pinder et al. 2000; Timms 2006: fig. 3) ( Fig. 4 View FIGURE 4 ). It is absent from acid gnammas in the Northcliffe area of far southwest of Western Australia, but does occur in rock pools in the forested Darling Range ( Bayly 1982, 1997; WAM 55624 View Materials –55626 above). To the north, it reaches as far as rock pools in the Mt Magnet–Yalgoo area, but not as far as Walga Rock near Cue ( Timms 2006, 2012).

There is also one record from the eastern side of the Nullarbor at Corrobinnae Rock on the northwest Eyre Peninsula ( Fig. 4 View FIGURE 4 ). Why this population exists well isolated at this site and not anywhere else on this eastern side of the Nullarbor is a mystery. Despite my sampling of gnammas on both sides of the Nullarbor on the same field trip, the Corrobinnae site was not sampled before the shrimp was discovered there. Waterfowl rarely visit, so they are probably not responsible either for its presence there ( Timms 2014). Most likely, eggs were blown across from the western Nullarbor or from further west, but they have not reached other Eyre Peninsula sites from this outlier as winds prevail from the west and almost all studied Eyre Peninsula gnammas as west of this site ( Timms 2014). The possibility that they were once more widespread and have since gone extinct is less likely as the Nullarbor limestone has always been arid with virtually no pools ( Williams 1978).

Paralimnadia badia   is a specialist inhabitant of pan gnammas and it has been found only rarely in other sites and then in pools nearby (e.g., Emu Rock east of Hyden, collection WAM C59568 View Materials above). It is present in such pans throughout most of the wet phase of the hydrological cycle in winter-spring (Timms 2012) and even appears in brief fillings after summer storms (W. Bayly, pers. comm.). Reproduction is by dioecy with mate guarding common ( Weeks et al. 2008; Benvenuto et al. 2009). Multiple hatching events within the one pool are not uncommon ( Benvenuto et al. 2009).
