The echinoid-associated pontoniine shrimp, Tuleariocaris holthuisi Hipeau-
Jacquotte, 1965 is a widely distributed species known from the east coast of
Africa (Hipeau-Jacquotte, 1965; Bruce, 1982), the north-east coast of Australia
(Bruce, 1990), Tahiti (J. Poupin, pers. comm.) and Hawaii (Castro, 1971; Hoover,
1998), as well as from the Gulf of California (Wicksten & Hern?ndez, 2000),
representing one of the very few Pontoniinae cases of a distribution spanning the
Indian Ocean, as well as the western and eastern Pacific Ocean (Bruce, 1972,
1987; De Grave, 2001). Previously, the only record of this species from the
eastern Pacific was based on two specimens collected in the Gulf of California,
Mexico (Wicksten & Hern?ndez, 2000). Herein, we report an ovigerous female of
Tuleariocaris holthuisi found in the Coiba National Park on the Pacific coast of
Panama, confirming its presence in the eastern Pacific and significantly increasing
the known range of the species. Postorbital carapace length (pcl., in mm) is used
as a standard length. The specimen collected is deposited in the first author?s
(IM) personal collection in the Laboratory of Ecology and Morphology of Marine
Invertebrates, A. N. Severtzov Institute of Ecology and Evolution of RAS, Moscow
(LEMMI).

Tuleariocaris holthuisi Hipeau-Jacquotte, 1965
(fig. 1)
Tuleariocaris holthuisi Hipeau-Jacquotte, 1965: 248, pls. 1-5 [type locality: Madagascar].
Material examined. ? One ovigerous female (pcl. 1.7 mm) (LEMMI), Pacific coast of Panama,
Coiba National Park, Isla Isabella, on spines of sea urchin Diadema mexicanum Agassiz, 1863, 2 m
depth, among coral rubble, coll. I. Marin, A. Anker, and J. Jara, 23.iii. 2007.
The specimen was found attached to the spines of a black sea urchin, Diadema
mexicanum, its only known host in the eastern Pacific (Wicksten & Hern?ndez,
2000). Other reported hosts in the Indo-western Pacific are the sea urchins,
Astropyga radiata (Leske, 1778), Echinothrix diadema (Linnaeus, 1758), Stomo-
pneustes variolaris (Lamarck, 1816), and Echinometra mathaei (De Blainville,
1825) (see Bruce, 1982).
At present, the genus Tuleariocaris Hipeau-Jacquotte, 1965 includes four
species, all associated with sea urchins: Tuleariocaris holthuisi; Tuleariocaris
neglecta Chace, 1969; Tuleariocaris sarec Berggren, 1995; and Tuleariocaris
zanzibaricus Bruce, 1967. Tuleariocaris sarec is known only from Mo?ambique
in association with the sea urchin, Echinometra mathaei (cf. Berggren, 1994).
Tuleariocaris zanzibaricus is a widely distributed Indo-west Pacific species known
from East Africa to Japan in association with Astropyga radiata, Diadema savignyi
Michelin, 1845, D. setosum (Leske, 1778), Echinothrix calamaris (Pallas, 1774),
and E. diadema (see Bruce, 1982). Tuleariocaris neglecta is the only species in
the genus known from the western and eastern Atlantic, from Florida, Dominica,
Barbados, Cura?ao (Chace, 1969), Puerto Rico (Castro, 1974), Colombia (Criales,

1984), Madeira (Chace, 1972), S?o Tom?, Pr?ncipe, and Cape Verde (Wirtz et
al., 1988; Wirtz, 2004) in association with the sea urchins, Diadema antillarum
(Philippi, 1845), and Astropyga magnifica Clark, 1934. All species of the genus
are usually clinging to the spines of their host echinoid, with their head turned
downwards, and exhibit similar colour patterns, with a dark red body and a
single white longitudinal band ventrolaterally. A key for the species was given
by Berggren (1994).
Biogeographically, the distribution of the genus Tuleariocaris is very interest-
ing, as it is one of only six pontoniine genera with an amphitropical distribution;
the others being Rapipontonia Marin, 2007, Palaemonella Dana, 1852, Periclime-
naeus Borradaile, 1915, Periclimenes Costa, 1844, and Typton Costa, 1844.
The material used in this study was collected with the support of the Smith-
sonian Tropical Research Institute. The authors express their gratitude to Dr. Nancy
Knowlton (Smithsonian Tropical Research Institute, Panama) for assistance in the
field work, and to Dr. Sammy De Grave (Oxford University Museum of Natural
History, Oxford) for valuable comments on the manuscript.
