Haswell’s original description of Xenocheira was of a female specimen only, collected in Port Jackson, New SOUTh Wales. MOOre (1988) was The firsT TO describe a male specimen of Xenocheira using material collected from Tasmania. This important contribution established that Xenocheira males are sexually dimorphic.</p> <p>Xenocheira is close to Bemlos Shoemaker, 1925 and Autonoe, which are all sexually dimorphic genera where the propodus of gnathopod 1 is larger in males. Xenocheira and Bemlos can be separated from Autonoe by the carpus of gnathopod 1 being shorter than the propodus in males. Xenocheira differs frOm Bemlos in the presence of an anterior carpal flanGe lined wiTh seTae On GnaThOpOd 2 in bOTh males and females.</p> <p>Xenocheira spp. are similar to Autonoe seurati Chevreux, 1907 which alsO has a flanGe and seTae, wiTh A. seurati being the only Autonoe species with this character state. Xenocheira can be separated from all Autonoe species by the mandibular palp article 3 straight posterodistal margin (versus concave); the gnathopod 1 carpus which is shorter than the propodus (versus subequal) and the uropod 3 rami with long robust and slender setae (versus robust setae only).</p> <p>Key to males of Xenocheira Haswell, 1879 species 1 Gnathopod 1 propodus palm weakly obtuse............................................................................. 2</p> <p>—— Gnathopod 1 propodus palm transverse to subacute................................................................. 3 2 Gnathopod 1 dactylus posterior margin smooth.................................

Haswell’s original published description of Xenocheira did nOT inclUde specific nOminaTiOn Of TYpe maTerial, bUT iT is siGnificanT ThaT OnlY a female specimen was described.Australian Museum collections of Xenocheira fasciata thought to be from W.A. Haswell collections include four slides which contain the partial dissection and disjointed carcass of a female. These slides are labelled “types” and “?Macleay Museum”, the institute where Haswell had been based. This material has been considered as a probable syntype, AM P.25466 (Springthorpe &amp; Lowry, 1994; Lowry &amp; Stoddart, 2003). Moore (1988) mistakenly cited AM P.25466 as a holotype.</p> <p>Additionally a female specimen among the Australian Museum Keith Sheard Collection labelled “Co-type. One Co-type mounted. KS” with a second label “ Xenocheira fasciata Hasw. Port Jackson ” was recently discovered (June, 2016). This material is a possible syntype of the set of slides associated with AM P.25466. A lectotype of the more complete female specimen is herein designated to stabilize the species name.</p> <p>This study extends the known distribution of X. fasciata to locations in both southern temperate Australian and tropical northern Australia. Material from Bynoe Harbour indicated that X. fasciata is sympatric with X. pirloti.</p> <p>The lobate carpus of gnathopod 2 and long slender seta on the carpus and propodus is seen in X. fasciata, X. pirloti and another aorid, Autonoe seurati (Chevreux, 1907), which is also reported from tropical northern Australia (Myers, 2009). The absence of long slender setae on the basis of gnathopods 1 and 2 separates X. fasciata and X. pirloti from A. seurati.</p> <p>Distribution. AUsTralia.

With increasing size, the male gnathopod 1 propodus becomes less elongate and more bulbous, as the posterior margin reduces and the anterior margin becomes more convex (Fig. 8).</p> <p>Remarks. PirlOT (1936) idenTified 3 specimens frOm The ArU Islands as Xenocheira fasciata Haswell, 1879. Based on Pirlot’s illustrations of gnathopods 1 and 2, Moore (1988) considered the variation in gnathopod 1 propodus length siGnificanTlY differenT frOm X. fasciata and established the new species name X. pirloti for the Aru Islands material without examining Pirlot’s original specimens. Pirlot’s material from the Siboga Expedition is currently held by the Department Invertebrates, Naturalis Biodiversity Center, Leiden, The Netherlands. Recent contact with the curator for Crustacea, Chelicerata and Myriapoda Karen Van DOrp cOnfirmed ThaT The TYpe maTerial (eiTher slide Or wet preparations) of X. pirloti could not be located and for now is considered presumed lost.</p> <p>Assessment of a large set of tropical Australia collections of Xenocheira pirloti included large adult males, gravid females and a range of smaller specimens has revealed the Aru Islands material are juvenile specimens of indeterminate sex and not adult males. A growth series of material is presented here to demonstrate the full development range of X. pirloti. This present description of additional material of X. pirloti supports this species as distinct from X. fasciata. Xenocheira pirloti is known from tropical waters in northern Australia and the Banda Sea in the Indonesian Archipelago while X. fasciata occurs in temperate waters along east coast and southern Australia including Tasmania.</p> <p>Xenocheira pirloti is most similar to X. fasciata in the male gnathopod 1 propodus palm with sinus. Xenocheira pirloti has an acute gnathopod 1 propodus palm while X. fasciata has an obtuse palm. See also remarks for X. fasciata. Distribution. Indonesia: Pulu Jedan, Aru Islands (Pirlot, 1936).
