( Figs. 10C , 14B , 16B , 17F ) Material examined. Holotype : female [photographed] (28.5 × 19.3 mm ) (MNHN-IU-2013-3042), stn CP4339, Ainto Bay , southeast New Britain , Solomon Sea , Papua New Guinea , 06°10’S 149°18’E , 510–743 m , coll. MADEEP Expedition, 7 May 2014 . Paratype : 1 female [photographed] (24.7 × 17.1 mm ) ( ZRC 2018.1498 , ex. MNHN-IU- 2013-3044), stn CP4339, Ainto Bay , southeast New Britain , Solomon Sea , Papua New Guinea , 06°10’S 149°18’E , 510–743 m , coll. MADEEP Expedition , 7 May 2014 . FIGURE 14. Overall dorsal view. A, Crocydocinus panglao n. sp. , holotype, ovigerous female (32.4 × 22.6 mm) (NMCR 50091), Philippines; B, C . porg n. sp. , holotype, female (28.5 × 19.3 mm) (MNHN-IU-2013-3042), Papua New Guinea; C, C . vanuatu n. sp. , holotype, male (16.0 × 11.0 mm) (ZRC 2011.1047), Vanuatu. Diagnosis. Carapace pyriform, covered with thick layer of setae, smooth when denuded. Pseudorostral spines straight, short, diverging in V ( Figs. 10C , 14B ). Supraorbital eave fused to carapace; pre-orbital lobe directed upwards; postorbital lobe cup-like. Carapace with regions well-defined, granules on each region; hepatic spine swollen at base; 4 distinct granules along medial line of carapace, 1 distinct mesogastric granule, 1 large metagastric granule, 1 oval urogastric granule, 1 large cardiac granule, and 1 thick posterior granule medially; 3 protogastric granules in a row along both margin of gastric region; 3 distinct granules fused basally on branchial region, 1 granule in front of branchial spine ( Figs. 10C , 14B ); 3 granules along lateral margin of carapace along branchial region ( Fig. 17F ). Antennal flagellum longer than pseudorostral spines. Basal antennal article longer than broad, stout, distal angle rounded. Buccal frame covered by third maxilliped, distal angle slightly protruded. Pterygostomial region with 3 granules on outer margin ( Fig. 16B ). Female chelipeds slender, covered with thick layer of setae except on fingers. Ambulatory legs slender, covered with thick layer of setae except dactylus; P2 longest. Etymology. The species is named after a Star Wars movie character, Porg, due to its woolly appearance. The name is used as a noun in apposition. Coloration. The color in life is orange-pink to brown ( Fig. 10C ). Remarks. The two female specimens of Crocydocinus porg n. sp. that are collected from the MADEEP cruise are superficially close to C . ewok n. sp. ( Fig. 13A ) and to C . panglao n. sp. ( Fig. 14A ). Crocydocinus porg n. sp. has the postorbital lobe and hepatic spine separate ( Fig. 17F ), similar to C . panglao n. sp. ( Fig. 17E ) (as compared to it being fused on C . ewok n. sp. ; Fig. 17A ); and has three granules along the lateral margin of the carapace along the branchial region ( Fig. 17F ) (versus one granule along the lateral margin of the carapace along the branchial region on C . ewok n. sp. and C . panglao n. sp. ; Fig. 17A, E ). Crocydocinus porg n. sp. is currently only known from its type locality, Papua New Guinea .
