Dissodactylus crinitichelis Moreira, 1901

(Figs. 21A, B)

Dissodactylus crinitichelis Moreira 1901: 37 [type-locality: Brazil; type in MNRJ]; Coelho & Ramos 1972: 196; Williams 1984: 438, fig. 530; Abele & Kim 1986: 64; Griffith 1987: 412; Melo 1996: 436, unnumbered fig.; Bertini et al. 2004: 2202; Almeida et al. 2010: 358; Boos et al. 2012: 1032; Poupin 2018: 232. Dissodactylus encopei Rathbun, 1901: 22, fig. 5 a–e; 1918: 119, figs. 67a–e, pl. 27, figs. 1–4; Williams et al. 1968: 56, fig. 12.

Distribution. Western Atlantic: Belize, British Honduras, Barbados, and Brazil (Rathbun 1901; Poupin 2018).

Material examined. Barbados, Old Chefette, St. James, subtidal, 13°10’45.13”N- 59°038’25.62”W, 1 ♀ CW: 3.5 mm (BLSZ 042) .

Remarks. The single specimen of Dissodactylus crinitichelis was caught by hand sub-tidally (~ 4 m deep) on the sand dollar Leodia sexiesperforata (Leske, 1778) . Telford (1978: 651–658) reported the species Dissodactylus crinitichelis and Dissodactylus primitivus Bouvier, 1917, for Barbados when investigating their distribution on their echinoid host. This report was followed by the genus revision of Griffith (1987: 397–422), who examined the specimens of Dissodactylus crinitichelis and Dissodactylus primitivus collected by Telford. Dissodactylus crinitichelis can be identified by a smooth flat carapace, the oral cavity is covered by the third maxilliped, and the abdominal segments of female specimens are separated (modified from Griffith 1987; Queiroz et al. 2011).
