Enosteoides lobatus Osawa, 2009: 158 View in CoL , figs. 1–3, 4A, B (type locality: Okinawa Island, Ryukyu Islands; low intertidal). — Osawa and McLaughlin, 2010: 110 (list), 126, fig. 1B.

Material examined. Philippines, PANGLAO 2004: Looc , Panglao Island, stn S18, 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 View Materials GoogleMaps .

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.
