( Figures 8 , 9 )

Trindade specimens. 1 male, cl 5.4 mm, 1 female, cl 4.7 mm ( MZUSP 36411 ), Brazil, off Espírito Santo, Trindade Island, Ponta Norte , 20º29’18.7’’S– 29º20’18.3’’W, 12.8 m, coll. J.B. Mendonça Jr, 17.vii.2013 .

Comparative material examined. Corallianassa longiventris : 4 males, 1 ovigerous female ( USNM 221700 ), Belize, Carrie Bow Cay , 1 m, R. B. Manning and D. Felder coll., 19.iv.1983 . 1 female, cl 22.8 mm ( USNM 266179 ), USA, Florida, Palm Beach, north of Peanut Island , 26º46’42’’N– 80º02’42’’W, coll. D. Felder et al., 12.viii.1987 . 1 male, cl 23.2 mm ( MZUSP 33843 ), 1 ovigerous female, cl 26.7 mm ( MZUSP 33844 ) , 1 male, cl 25.5 mm, 1 female, cl 26.2 mm ( MZUSP 39506 ), Brazil, Bahia, Boipeba Island, Bainema reef, coll. M. Tavares et al., 17–31.i.2015 . Corallianassa hartmeyeri ( Schmitt, 1935) : 1 male, 3 females ( USNM 221942 ), F. Chace det., Ascension Island, Shelly Beach, Jones et al., coll. ASC–5A–76, 13.vii.1976 .

Distribution. United States ( Bermuda, Florida), Gulf of Mexico, Caribbean Sea ( Belize, Jamaica, Virgin Islands, Martinique), and Brazil (Pará, Rocas Atoll, Trindade Island) ( Coelho 1997; Sakai 2005; Felder et al. 2009; present study). Central Atlantic: Ascension Island ( De Grave et al. 2017).

Remarks. Manning (1988) showed that Corallianassa hartmeyeri differs from C. longiventris in having the major cheliped carpus about half of the dorsal length of the palm, and the ventrodistal carpal margin produced into a spine on both first pereopods (absent in C. longiventris ). Contrarily, Sakai (2011: 430) synonymized C. hartmeyeri with C. longiventris (both as Glypturus ) because of their similar male pleopods 1 and 2. Sakai never discussed the distinguishing characters outlined by Manning (1988). The Trindade specimens studied herein were compared to both, C. hartmeyeri and C. longiventris , and agree with other material of C. longiventris . De Grave et al. (2017) recently recorded C. longiventris from the Ascension Island, from where C. hartmeyeri was already known ( Manning & Chace 1990).
