Glabropilumnus seminudus (Miers, 1884)

(Fig. 16A–C)

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 29, 2 ƏƏ (CB 10.4×CL 7.4 mm; 22.6× 16.2 mm), NSMT-Cr 30748; 1$ (17.8× 12.1 mm), NSMT-Cr 30749. — Sta. 30, 1Ə (CB 11.2×CL 7.9 mm), NSMT-Cr 30750.

Remarks. Glabropilumnus seminudus is characterized by the smooth carapace with a band of a close velvety pubescence along the carapace frontal and anterolateral margins (Fig. 16A–B), and the reticulated appearance of four longitudinal lines of granules on the palm outer surface (Fig. 16C). The setation of the carapace dorsal surface may be somewhat variable, with rather shorter and sparse setae in the present specimens different from the longish dense setae in the Arafura Sea specimens reported by Takeda and Miyake (1969c: pl. 1 fig. B). Good figures are otherwise given by the original author (Miers, 1884: pl. 22 fig. B, as Pilumnus), Rathbun (1923: pl. 24 figs. 1, 2, as Pilumnus), and Galil and Takeda (1988: figs. 3D, 5).

Distribution. Queensland, Australia; Torres Strait; Arafura Sea; Hong Kong; Makassar, Celebes. Edmondson (1952, 1962) recorded a specimen from biofouling on the hull of a barge in Pearl Harbor, Oahu Island, which had service in Guam for two years. The recorded bathymetric range is from 7 to 30 m depth. Davie (2002) listed this species as one of four Australian species of Glabropilumnus .
