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 Ara- fura 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 .
