Diagnosis. Carapace pyriform with tomentum of setae, with long tufts of setae along edge of gastric region (Fig. 10B). Pseudorostral spines straight, diverging in V (Figs. 10B, 13A). Post-orbital lobe fused with hepatic lobe forming plate-like protrusion, thin plate protruding outwards (Fig. 17A). Carapace regions well-defined, with granules on each defined region (Figs. 10B, 13A). Basal antennal article longer than broad, roundish outer margin (Fig. 15A). Pterygostomal region with 3 rounded granules fused basally (Fig. 15A). Male thoracic sternum slightly depressed anteriorly (Fig. 15A). Male pleon with telson and 6 somites free; telson triangular with round margin (Fig. 15A). G1 relatively straight, laterally flattened with distal tip sharp (Fig. 18 A–D).

Description. Carapace pyriform, with tomentum of setae, with long tufts of setae along edge of gastric region, smooth when denuded (Figs. 10B, 13A). Pseudorostral spines straight, diverging, V-shaped. Supraorbital eave fused to carapace; pre-orbital lobe directed outwards. Post-orbital lobe fused with hepatic lobe forming plate-like protrusion, with thin plate protruding outwards (Fig. 17A). Carapace regions well-defined, with granules; median small granule on gastric region, long oval-shaped granule on metagastric region, mushroom-shaped urogastric granule fused to metagastric oval-shaped granule, single small granule at base of urogastric region; Y-shaped granule on cardiac region, extending towards posterior margin; strong thick posterior spine with blunt squarish tip; large granule on branchial region, with tip appearing trified, with low swelling behind large granule; thick branchial spine; single small granule along lateral margin of carapace at branchial region (Figs. 10B, 13A).

Antennal flagellum equal in length or longer than pseudorostral spines. Antennules completely retractable in deep fossae. Basal antennal article longer than broad, rounded outer margin. Presence of granule at base of article. Buccal frame covered by third maxilliped, distal angle of frame slightly protruded. Pterygostomial region with 3 fused, rounded granules (Fig. 15A).

Male cheliped with margins of merus, carpus, propodus, and palm of chela carinate; palm of chela inflated; carpus with single carina on outer margin; merus triangular in cross-section, carinate on all margins (Fig. 13A). Ambulatory legs long, P2 longest; merus, carpus, and propodus covered with setae; dactylus with sharp, curved tip.

Male thoracic sternum slightly depressed anteriorly; sternites 1–4 fused without median sutures, broad; lateral margins of sternites 3 and 4 slightly constricted, surface concave. Male pleon with telson and 6 somites free; telson triangular with round margin (Fig. 15A). Adult female pleon rounded, with all somites and telson free. G1 relatively straight, flattened with distal tip sharp (Fig. 18 A–D).

Etymology. The species is name after a Star Wars movie character, Ewok, due to the fuzzy and woolly appearance of the new species. The name is used as a noun.

Coloration. In life, chela and top half of carapace pinkish to orange; remainder of carapace and walking legs whitish to pale pink (Fig. 10B).

Remarks. Crocydocinus ewok n. sp. is superficially similar to Tunepugettia species in the general morphology, but has more granules on the carapace (Figs. 13, 14), the ambulatory legs do not have the segments carinate, and the G1 does not have the bifid tip (Fig. 18 A–D), which are characteristics of species of Tunepugettia .

Crocydocinus ewok n. sp. is currently only known from its type locality, Astrolabe Bay, Papua New Guinea.
