Colour in life. ( Fig. 15AView FIGURE 15). Base colour of body orange-red with distinct white median band along carapace and abdomen. Walking legs banded with darker red transverse bands. Cheliped with some white patches along distal portion of palm and fingers. Eyes pale yellow. (Based on 3.5 mm ovigerous female, NIWA 56096).

Parasites. Four lots included a specimen each with a kentrogonid rhizocephalan externa under the abdomen (NIWA 10124, 10880, 21254 and 135614) and one specimen had a bopyrid in its branchial cavity (NIWA 73492). A female (NIWA 21254) had both a rhizocephalan and a bopyrid parasite.

Genetic data. Eight specimens from across the New Zealand distribution were sequenced for the partial COI gene (the holotype NIWA 92587, paratypes and non-types from NIWA 33656, 122226, 56530, 57421, 108588 and 44747; see Table 1).

Etymology. This species name is derived from the Latin australis  meaning southern, highlighting the wide distribution from New Zealand to the Great Australia Bight, South Australia.

Distribution. New Zealand continental shelf, from the Snares to the Three King Islands and northwards to Norfolk Island, and westward to southern Australia (New South Wales to South Australia); 15– 366 m. The median depth of occurrence is 114 m and this species primarily appears to inhabit depths of <200 m ( Fig. 3View FIGURE 3).

Remarks. Phylladiorhynchus australis  n. sp. is one of the most common species of the genus in the region and is characterised by the combination of four epigastric spines, a medially uninterrupted metagastric ridge, a convex lateral margin of the rostrum, a distinct posterior transverse ridge on the third abdominal tergite, the anteriorly scalloped sternite 3, the distinct lateral spine on the basal antennular article, small mesial spine on antennal article 2 and distolaterally unarmed article 3. The new species is morphologically and genetically most similar to P. nui  n. sp., which is also very common around New Zealand. These two species can be difficult to separate morphologically but appear to have largely separate bathymetric ranges with only limited overlap: 15–366 m (usually <200 m) versus 46–1266 m (usually> 200 m) ( Fig. 3View FIGURE 3 inset). Phylladiorhynchus australis  attains a smaller size (pcl 1.4–6.1 mm, mean slightly exceeding 3.0 mm) than P. nui  (pcl 2.2–10.7 mm, mean nearly 6.0 mm). Distinguishing characters are discussed below under the account of the latter species.

Most of the material examined of P. australis  had previously been identified as P. pusillus  based on the presence of two pairs of epigastric spines, but P. australis  is relatively easily distinguished from P. pusillus  s.s. by the combination of a medially unbroken metagastric ridge (broken in P. pusillus  .), the biconcave and ‘scalloped’ anterior margin of sternite 3 (convex in P. pusillus  .), the transverse posterior ridge on tergite 3 (usually absent in P. pusillus  .) and a very small or absent mesial spine on antennal article 3 (small but distinct in P. pusillus  ). Interestingly, both species can co-occur (e.g., Stn. TAN0906/130 and SAM Stn. DCE_100).

Specimens reported as Galathea pusilla  by Chilton (1906) (Channel Islands, Hauraki Gulf) and Chilton (1911) (from 1907 Nova Niven Station 30) are identified here as P. australis  on the basis of photographs of the specimens kindly provided by Jonathan Ridden and Cor Vink (Canterbury Museum, Christchurch). Similarly, Thomson’s (1899) records of G. pusilla  (OM IV14562, 14565, 14566, examined here) are referable to P. australis  .

Of the seven specimens reported by Borradaile (1916) as Galathea pusilla  from Terra  Nova Stations 90 (183 m) and 96 (128 m) off Northland, only those from Station 96 could be examined and confirmed as P. australis  . Both stations lie in close proximity and specimens from Stn. 90 could also belong to P. australis  .
