Parapagurus pilosimanus Smith, 1879: 51 (type locality: off the coast of Nova Scotia).— Lemaitre, 1986: 529, figs. 1C, D, 3A– E, 4C, D, 5E, F, 6I, J, 7C, G, 8H, 9F–H.— Lemaitre, 1989: 13, FIG. 3 , 4 , 5 A, 6, 39A, B.— Lemaitre, 1999: 308, fig. 47.— McLaughlin et al., 2010: 39.— Cardoso & Lemaitre, 2012: 597, fig. 4.

Eupagurus jacobii A. Milne-Edwards, 1880: 42 (syntypes from Caribbean Lesser Antilles: Guadeloupe, St. Lucie and Martinique).

Sympagurus Grimaldii A. Milne-Edwards & Bouvier, 1897: 134 (type locality: Azores, L’Hirondelle, sta 211, 39°18’N, 33°32’W).

New material. Southwestern Atlantic. Brazil: Rio Grande do Norte: sta MT 74, 04°33.9768’S, 36°41.8026’W, 987 m, 15 May 2011: 1 male 8.8 mm (in zoanthid) ( MZUSP 25789).

Diagnosis. See Lemaitre (1986, 1989).

Distribution. North, Central and South Atlantic ( Lemaitre 1989, 1999; Cardoso & Lemaitre 2012). Depth: 102 to 3864 m.

Color ( Fig. 23A ). Freshly collected specimen (MZUSP 25789) with shield and ocular peduncles dirty white or cream, with light orange tones near anterior and posterior margins, somewhat iridescent. Antennules and antennae reddish. Chelipeds dirty white or cream; dactyls light orange distally; meri proximally with light orange tone fading distally to dirty white or cream. Ambulatory legs light orange with orange tone darker on dactyls.

Remarks. Despite this species being one of the most common and widely distributed parapagurids on the North, Central and South Atlantic, it had never before been reported in the western Atlantic further south than off the coast of French Guiana. Thus, this report extends the range of this species considerably to the south, from about 7°46’N ( Lemaitre 1989) to 4°33’S off the coast of Rio Grande do Norte, Brazil.
