03E5F122CD35FF9DBA86FADBFBC13C29.taxon	materials_examined	Material examined. Philippines, PANGLAO 2004: Looc, Panglao Island, stn S 18, 9 ° 35.7 ’ N 123 ° 44.4 ’ E, 0 – 2 m, subtidal platform, mixed bottoms, 18 June 2004, 1 ovigerous female (cl 2.5 mm), ZRC 2016.0057. Coloration. Unknown in the present specimen. In the fresh specimens collected from the Ryukyu Islands, the carapace is cream or reddish brown, and the chelipeds and second to fourth pereopods (ambulatory legs) are reddish brown (Osawa, 2009; Osawa and McLaughlin, 2010). Distribution. Previously only known from the Ryukyu Islands in south Japan, intertidal to subtidal depths of 3 – 5 m, under rock or within narrow space underneath dead coral block (Osawa, 2009). Now also from the Philippines. Werding et al. (2016) found material of E. lobatus from Papua New Guinea in the collection of the Muséum National d’Histoire Naturelle (MNHN), Paris, and also recorded the species based on direct field observations in the Lembeh Strait, Indonesia. However, the specimens that they observed in the Lembeh Strait are probably referred to E. turkayi n. sp. described below, not E. lobatus (see the Remarks for the new species). Remarks. The present specimen agrees well with the original description of E. lobatus by Osawa (2009). It is the smallest (cl 2.5 mm) among the reported specimens and is ovigerous. This is the second occurrence record of this rare species.	en	Osawa, Masayuki (2016): Enosteoides Johnson, 1970 (Crustacea: Decapoda: Anomura: Porcellanidae) from the Central Philippines, with description of a new species of the genus.

Philippines, PANGLAO 2004: Sungcolan Bay, Panglao Island, stn S 7, 9 ° 38.5 ’ N 123 ° 49.2 ’ E, 1 – 4 m, sand with seagrass, 9 June 2004, 1 female parasitized by rhizocephalan (cl 2.6 mm), ZRC 2016.0058. Coloration (Fig. 1 B). Carapace and chelipeds generally white with pale brown tint. Second to fourth pereopods with meri white on proximal 0.7 and remaining part dark red; carpi and propodi entirely dark red; dactyli also dark red proximally and whitish distally. Distribution. Ryukyu Islands in south Japan, Hainan Island in south China, Palau, and New Caledonia; low intertidal to subtidal depths of 7 – 31 m; interspace of dead coral block (Osawa, 2007; 2009). Now also from the Philippine waters. Remarks. The present specimen agrees well with the original description by Nakasone and Miyake (1968, as Porcellana) and a short description by Osawa (2009) of E. palauensis. Osawa (2007) considered that E. hainanensis Yang and Sun, 2005 is synonymous with E. palauensi s because the distinctions discussed by Yang and Sun (2005) were insufficient to distinguish the two species based on the re-examination of the type material of E. palauensi s. The sole specimen examined is parasitized by a rhizocephalan of the family Lernaeodiscidae.	en	Osawa, Masayuki (2016): Enosteoides Johnson, 1970 (Crustacea: Decapoda: Anomura: Porcellanidae) from the Central Philippines, with description of a new species of the genus.

Palm weakly convex on dorsal surface; longitudinal, elevated crest of short rows of beaded granules present on dorsomidline; posterior margin slightly elevated dorsally to form blunt, weakly crenulated crest; ventral surface convex on midline, sometimes with sparse, short plumose setae, anterior half somewhat concave.

Telson (Fig. 2 F) composed of 7 plates, broader than long, generally similar between male and female; posterior plates slightly longer than broad. Male with pair of pleopods modified as gonopods on second abdominal segment (Fig. 2 J); endopod elongate ovate, not distinctly twisted, with marginal setae; exopod small. Female with pairs of developed pleopods on third to fifth abdominal segments, third pair slightly smaller than fourth and fifth pairs. Variation. Two large specimens (cl 4.5 mm: female holotype, NMCR, and male paratype, ZRC 2016.0061) differ from other smaller specimens (cl 2.3 – 3.9 mm) in some characters. The short plumose setae on the ridges of the dorsal carapace surface are reduced in size and number in the two large specimens than in the others. The sharply pointed spines on the posterior margin of the carpus and anterior margin of the palm of the cheliped in the small specimens greatly weaken in the two large specimens. The anterior margin of the chela also has a distinct row of plumose setae in the small specimens, but it bears only a few very short setae in the two large specimens. Coloration (Fig. 1 C, D). Carapace and chelipeds generally white, with reddish and dark brown blotches. Second to fourth pereopods with meri white on entire part or proximal 0.9 with remaining part bright red; entire parts of carpi and proximal 0.9 of propodi bright red, distal 0.1 of propodi white; dactyli whitish, each with pale or bright red band medially. Distribution. Central Philippines around Bohol, Panglao, and Balicasag Islands; depths ranging from 3 – 5 to 80 – 150 m; coral rubble, sand, and mud. Etymology. The present new species is named in honor of the late Dr. Michael Türkay, for his great contribution to the systematics of various groups of decapod crustaceans. Remarks. The new species resembles E. melissa and E. philippinensis in that the rostrum is at most slightly tuberculate on the anterior margin and has lateral lobes usually bluntly produced, the palm of the cheliped is moderately broad and not distinctly tuberculate on the dorsal surface, and the meri and propodi of the second to fourth pereopods are relatively slender. However, E. turkayi n. sp. is immediately distinguished from E. melissa and E. philippinensis by having the third thoracic sternite without an anteriorly produced median lobe, unlike the distinct and broadly rounded median lobe in the latter two species. Additionally, E. turkayi n. sp. lacks some, distinct rounded tubercles on the gastric region and anterior branchial regions of the carapace as possessed by E. melissa and E. philippinensis, and has much less setose pereopods than in the latter two species. The shape of the third thoracic sternite links E. turkayi n. sp. to E. lobatus, but the latter species clearly differs from the new species in having the lateral lobes of the rostrum that are narrow and subtriangular, instead of broader and usually bluntly produced and in the absence of dense plumose setae on the ventroposterior distal surface of the chela and cutting regions of the fingers. The fresh coloration also distinguishes E. turkayi n. sp. from E. melissa and E. philippinensis. The carapace and chelipeds are generally white with brown blotches in the new species, instead of being pale pink to brown or mottled dark brown in E. melissa and E. philippinensis. The carpi and propodi of the second to fourth pereopods are bright red for most part in the new species, whereas such color pattern is not seen in E. melissa and E. philippinensis (Osawa, 2009; 2013; Dolorosa and Werding, 2014; Fig. 1 A). The red-colored carpi and propodi of the ambulatory legs are shared by E. palauensis and E. turkayi n. sp. However, E. palauensis is different from E. turkayi n. sp. by having the narrower rostrum with indistinct lateral lobes, the broader chelae, and the comparatively stouter ambulatory legs (Osawa, 2009; Fig. 1 B, for E. palauensis).	en	Osawa, Masayuki (2016): Enosteoides Johnson, 1970 (Crustacea: Decapoda: Anomura: Porcellanidae) from the Central Philippines, with description of a new species of the genus.
