03DC8788D40C9E1BFF45A5C4FB07C627.taxon	diagnosis	Diagnosis: Carapace triangular. Rostrum composed of 2 flattened, ear-shaped horns which are closely clustered. Carapace with raised plates arranged as follows: 2 semicircular supraocular plates; 1 gastric plate composed of 2 parts, long slender anterior gastric part connected with small posterior transverse part; 1 cardiac plate regularly curved, connected to posterior border of carapace, forming typically mushroom-shaped structure; 2 large branchial plates fused with 2 hepatic plates (Fig. 1 A, 2 A); branchial plate with deep notch on interior side (Fig. 1). Eyes small with dark, round cornea, protected by anterior part of hepatic plate. Antennae very short. Antennules inserted inside fossae. Quadrangular buccal frame closed by third maxillipeds. Thoracic sternal sutures with deep obliquely transverse grooves (Fig. 1 B). Chelipeds inflated, with smooth surface, sharp fingers. Ambulatory legs with articles cylindrical in cross-section; dactyli long, curved, sharp. Second pereopod subequal in length to cheliped. Male abdomen with seven somites, including telson. First male gonopod almost straight, flattened apically (Fig. 2 A – B). Live specimen orange-red. Etymology: The species is dedicated to Christian Fitialeata, a sailor of the R. V. Alis, a good man and esteemed colleague who suddenly passed away in Rabaul under unfortunate circumstances during the BIOPAPUA cruise.	en	Forges, Bertrand Richer De, Corbari, Laure (2012): A new species of Oxypleurodon Miers, 1886 (Crustacea, Brachyura, Majoidea) from the Bismarck Sea, Papua New Guinea.

03DC8788D40C9E1BFF45A5C4FB07C627.taxon	discussion	Remarks: Oxypleurodon christiani n. sp. belongs to the Oxypleurodon group of species which has short flattened rostral spines (Fig. 3). The other species in this group are O. auritum (Rathbun, 1916), O. boholense Richer de Forges & Ng, 2009, and O. barazeri Richer de Forges & Ng, 2009. Oxypleurodon christiani n. sp. is easily distinguishable from O. barazeri, where the carapace is more rounded with less marked dorsal plates less marked than in the new species (Fig. 3 A versus Fig. 3 D) (Richer de Forges & Ng 2009: 252, fig. 3 C). The main difference between O. christiani n. sp. and O. boholense is in the rostrum, which has sharp, diverging spines in O. boholense (Fig. 3 C) (Ng et al. 2008: 107, fig. 88; Richer de Forges & Ng 2009: 252, fig. 3 D) but rounded and clustered spines in O. christiani n. sp. (Fig. 3 A). In O. christiani n. sp., the large cardiac plate is fused with the intestinal plate, forming a mushroom-shaped structure, in contrast to O. boholense where there are only a few marked intestinal plates (Fig. 3 C). The long branchial plate is separated from the hepatic plate by a deep gap in O. boholense, whereas these two plates are completely fused in O. christiani n. sp. (Fig. 1 C).	en	Forges, Bertrand Richer De, Corbari, Laure (2012): A new species of Oxypleurodon Miers, 1886 (Crustacea, Brachyura, Majoidea) from the Bismarck Sea, Papua New Guinea.
