Ecological notes.
Banareia palmeri
is rare in the collections. It has been reported in association with the coral
Porites furcata
Lamarck
and sponges (Rathbun, 1924;
Boone 1930b
, respectively). The male USNM 53765 from St. Thomas was found in association with a sponge (see above under comparative material examined). The juvenile female from Trindade was found in association with the octocoral
Plexaurella regia
Castro
(Tavares
et al.
2017: 158, fig. 1E).
Felder
et al.
(2009)
reported
B. palmeri
from rubble to depths of
145 m
.
Remarks.
The young Brazilian specimens (
Rio Grande do Norte
and Trindade, see above under comparative material) are distinctly less coated with setae when compared to the thick coated adults from northern localities (
Fig. 31A–F
). Additionally, the juvenile female from Trindade (
Fig. 31A, B
) differs in that the cheliped fingers cross in closed position and the longitudinal rows of granules on the lateral lower part of the cheliped propodus are rather inconspicuous, whereas the lateral lower part of the cheliped propodus has well marked rows of granules, even in the young specimens of about the same size from
Rio Grande do Norte
. More material from Trindade is needed to judge if these differences warrant recognition of a new species.
