Uropod 3 strongly extended, not sexually dimorphic, distinctly larger than uropod 1, parviramous; outer ramus cylindrical with two articles, second article apically concave; inner ramus short and scale-like. Telson longer than broad, deeply cleft into two lobes, with lateral setae and long apical penicillate setae.</p> <p>Etymology. The name Pilbarana references the Pilbara region of Western Australia where this genus is found. The gender should be considered as female.</p> <p>Remarks. Pilbarana gen. nov. was placed within Eriopisidae by King et al. (2022, labelled ‘ Eriopisidae gen. undet.’) as a reciprocally monophyletic lineage based on COI mtDNA and 28S rRNA molecular data and due to the presence of eriopisid morphological characters: biramous and enlarged third uropod, one or multiple robust basofacial seta(e) on the peduncle of the first uropod, the lack of sternal gills, and the absence of sexually dimorphic second gnathopods (Lowry &amp; Myers 2013). King et al. (2022) further indicated that Pilbarana, together with Nedsia and Norcapensis, the two additional WA subterranean eriopisid genera, are genetically divergent from the morphologically similar Australian melitid genera, Brachina Barnard &amp; Williams, 1995 and Nurina Bradbury &amp; Eberhard, 2000, supporting the current morphological-based classification of Lowry &amp; Myers (2013).</p> <p>Morphologically, Pilbarana is expectedly more similar to Nedsia and Norcapensis than any of the east coast Australian marine and estuarine eriopisid genera: Eriopisella Chevreux, 1920, Netamelita J. L. Barnard, 1962, and Victoriopisa Karaman &amp; Barnard, 1979. It appears to be closest to Norcapensis particularly due to the larger body size compared to Nedsia, a mandible palp of three articles, similarly enlarged second gnathopods, and strongly extended, cylindrical third uropods. Pilbarana, however, can be easily differentiated since Norcapensis: lacks an antennal sinus; comprises an elongate first antenna, reaching past half body length; maxilla 1 inner plate consists of a row of distal plumose setae; possesses a markedly robust rather than vermiform body shape with the first pereonite lacking a distinctly concave or ‘cut out’ posterodistal corner and pereonites 2–7 around 2 times as long as broad; comprises coxal gills on coxae 2–6; first gnathopod with carpus equal in length to propodus; pereopods 5–7 bases progressively more expanded posteriorly; uropod 1 peduncle is approximately equal in length to rami; and uropod 3 outer ramus second article is not apically concave. Pilbarana is, additionally, distinct from Nedsia as Nedsia, like Norcapensis, lacks an antennal sinus and possesses elongated first antennae, but further consists of comparably smaller second gnathopods, and third uropods that are leaf-shaped rather than cylindrical.</p> </div>	https://treatment.plazi.org/id/03D4B3124870FF92FF2148B9ECB6FC29	Public Domain	No known copyright restrictions apply.

Uropod 2 (Fig. 4B) peduncle similar in length to inner ramus, row of setae along dorsal margin. Uropod 3 (Fig. 4C) outer ramus cylindrical with 2 articles, first article approximately 1.6 times length of second article.</p> <p>Distribution. Cane River Conservation Park, Ashburton River Basin, Pilbara, Western Australia.</p> <p>Etymology. This species name is taken from the Latin word ‘grandis’, and refers to the large body size of this and other species of Pilbarana.</p> <p>Remarks. Overall, the two new species of Pilbarana can be distinguished morphologically based on the shape of the antennal sinus, the length and elongation of antennal articles, differences in the shape of coxae, the length of the first gnathopod propodus, the number of robust basofacial setae on the peduncle of the first uropod, and the length of the peduncle of the second uropod versus the length of the rami. Examination of specimens of P. grandis sp. nov. has revealed that individuals may possess between two (most common) and four robust basofacial setae on the peduncle of the first uropod, with the number of basofacial setae further fluctuating, in some cases, between the pair of uropods for a single specimen. Specimens (except for juveniles), nonetheless, never possess only a single basofacial seta, contrasting with specimens of P. lowryi sp. nov. that always exhibit only one robust basofacial seta on the peduncle of the first uropod. The number of robust basofacial setae on the peduncle of uropod 1 is one of the few morphological characters that separate distinct lineages of Nedsia from the Pilbara (King et al. 2022) and, consequently, appears to represent a useful and consistent distinguishing eriopisid trait.</p> <p>Molecular analyses further revealed that the two new species of Pilbarana are highly divergent genetically, with approximately 13–14.5% COI divergence estimated (with 0.2% between sequences of P. grandis individuals). This level of divergence is well above the 5–10% threshold principally followed by King et al. (2022) in their description of new Nedsia species, and is indicative of long-term isolation in discrete (and distant) subterranean habitats. Pilbarana grandis has, thus far, only been sampled from one well in the Cane River Conservation Park in the Pilbara region and is located approximately 250 km from bores in the Fortescue Basin where P. lowryi was collected (Fig. 1).</p> </div>	https://treatment.plazi.org/id/03D4B3124877FF91FF214AF7EDA8FC60	Public Domain	No known copyright restrictions apply.

Named in honour of Dr Jim Lowry for his substantial and valuable contribution to Australian amphipod taxonomy.</p> <p>Remarks. Specimens of P. lowryi sp. nov. were sampled from three bores within the Fortescue River Basin near the Hamersley Range in the central area of the Pilbara, approximately 60–70 km north of the town of Tom Price (Fig. 1). The holotype specimen was collected from a deposit within the Solomon Mining Project, while paratypes were sampled from bores outside the impacted region. These specimens were found to be morphologically identical, and molecular analyses revealed relatively low molecular COI divergence estimates of between 2.8–3.1%. These divergences suggest some slight phylogeographic structuring of populations, potentially due to distance between collection sites, but are, nonetheless, within the range of amphipod intraspecific variation (Tempestini et al. 2018; King et al. 2022). In addition, no juveniles were examined and so should be assessed in further collections, and no morphological differences were observed between males and females (as for P. grandis sp. nov.).</p> </div>	https://treatment.plazi.org/id/03D4B3124874FF9EFF214FD3ECEEFA3B	Public Domain	No known copyright restrictions apply.
