Ecology
.
Shallow reef and adjacent rubble and sand flats with abundance of sponges; typical depth range in the Caribbean-Florida area:
1–15 m
, possibly deeper in
Brazil
:
35–40 m
; obligate symbiont of demosponges, e.g.,
Lissodendoryx
cf.
strongylata
,
L. colombiensis
,
Agelas clathrodes
,
Hyattella intestinalis
and
Hymeniacidon amphilecta
(

)
; typically in heterosexual pairs.

Remarks
.
Many records of
S. pandionis
prior to
Ríos & Duffy’s (2007)
revision of the
S. longicarpus
species complex possibly refer to the closely related
S. ul
,
S. yano
and
S. dardeaui
.
Synalpheus pandionis
differs from these species by the presence of a relatively small but conspicuous bump on the mesial side (not lateral side, error in
Ríos & Duffy 2007
) of the major chela pollex, best visible in ventral view of the major chela (see
Ríos & Duffy 2007
: fig. 24F).
Ríos & Duffy (2007)
discussed the synonymy of
S. grampusi
Coutière, 1909
and
S. pandionis extentus
Coutière, 1909
with
S. pandionis
, which is followed herein.
The single specimen from
Ceará
represents the first record of
S. pandionis
for
Brazil
, considerably extending the previously known range of this species, from Florida, Gulf of Mexico and the Caribbean Sea (
Ríos & Duffy 2007
) to northeastern
Brazil
(see map in
Fig. 52
). The Brazilian specimen corresponds closely to
S. pandionis
as illustrated by
Coutière (1909)
,
Dardeau (1984)
, and
Ríos & Duffy (2007)
, including the presence of the diagnostic mesial protuberance on the major chela.
