Material examined

MARTINIQUE • 1 juv.; Baie de Sans-Souci ; 14°34.7ʹ N, 60°50.7ʹ W; depth 0–1 m; 9 Oct. 2016; st. AM325; MNHN-IU-2016-1100/ MK411049 • 1 ♀; Trois Rivières; 14°27.8ʹ N, 60°57.9ʹ W; depth 3–4 m; 25 Sep. 2016; st. AB356; MNHN-IU-2016-1165/ MK411068 .

Remarks

These specimens were collected at two localities on Atlantic and Caribbean coasts. This species differs from most of other Anoplodactylus by the combination of the following characters: lateral processes separated by more than their own diameter, less than twice; low rounded tubercles on the lateral processes; chela fingers simple; leg articles elongated; auxillary claw present, short; length of propodal lamina about half that of propodal sole. The species furthermore differs from A. dissitus Child, 2004 in showing no tubercle on coxae 1; from A. trispinosus Stock, 1951 in having slenderer leg articles ( Stock 1975a; Child 2004; Müller & Krapp 2009). This species could be assigned to A. petiolatus (Krøyer, 1864) , A. arcuatus Child, 1977 or another undescribed species. Without male specimens it is, however, impossible to provide a definitive conclusion.

Depth range

0– 3 m.
