( Figs. 10C View FIGURE 10 , 14B View FIGURE 14 , 16B View FIGURE 16 , 17F View FIGURE 17 )
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 GoogleMaps . Paratype: 1 female [photographed] (24.7 × 17.1 mm) ( ZRC 2018.1498 View Materials , 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 GoogleMaps .
Diagnosis. Carapace pyriform, covered with thick layer of setae, smooth when denuded. Pseudorostral spines straight, short, diverging in V ( Figs. 10C View FIGURE 10 , 14B View FIGURE 14 ). 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 View FIGURE 10 , 14B View FIGURE 14 ); 3 granules along lateral margin of carapace along branchial region ( Fig. 17F View FIGURE 17 ). 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 View FIGURE 16 ). 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 View FIGURE 10 ).
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 View FIGURE 13 ) and to C. panglao n. sp. ( Fig. 14A View FIGURE 14 ). Crocydocinus porg n. sp. has the postorbital lobe and hepatic spine separate ( Fig. 17F View FIGURE 17 ), similar to C. panglao n. sp. ( Fig. 17E View FIGURE 17 ) (as compared to it being fused on C. ewok n. sp.; Fig. 17A View FIGURE 17 ); and has three granules along the lateral margin of the carapace along the branchial region ( Fig. 17F View FIGURE 17 ) (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 View FIGURE 17 ). Crocydocinus porg n. sp. is currently only known from its type locality, Papua New Guinea.
