Edges of third maxillipeds, first and second pereiopods red. Third pereiopods merus, carpus red; ischium, proximal propodus edged in red; distal propodus, dactylus white. Fourth, fifth pereiopods mostly whitish to transparent with few red spots along edges. Ovary and eggs blue. Development. Ovigerous females ranged in size from 5.2–5.4 mm postorbital carapace length, 18.1–18.4 mm total length and carried 10– 11 eggs. Eggs at blastula stage with undifferentiated yolk cells were 1.20 × 1.62 mm in size. Type locality. 22°24'12"S 46°06'18"W at Campos Basin, Rio de Janeiro, Brazil. Distribution: 31°386'N 78°6033'W off Sapelo Island, Georgia, USA; 27°35.89'N 91°49.60'W and 27°44.81'N 91°13.44'W Green Canyon, Gulf of Mexico. Habitat. The holotype was sampled at a deep sea coral reef at a depth of 621 m by means of a ROV (remotely operated vehicle). The species’ deepest record is from off Sapelo Island at 665 m. Six cruises from 2002 to 2005 recorded 84 specimens of the species by means of the deep-sea submersible Johnson-Sea-Link at primarily two locations, Green Canyon and Viosca Knoll in the Gulf of Mexico at depths from 459 to 525 m with an average depth of 489m. The use of deep-sea human operated orb remotely operated vehicles allowed the observation of the species’ association with live or dead coral branches of Lophelia pertusa , a foundation species that is found throughout the world’s oceans on topographic features (Rogers 1999). Etymology. The species is named for its association with the deep-sea coral Lophelia pertusa. Remarks. Both Odontozona edwardsi and O. lopheliae sp. nov. closely follow the definition of the genus Odontozona given by Holthuis (1946) and are most closely similar to each other as well as O. spongicola (Alcock & Anderson 1899) from deep water in the Pacific. The genus Odontozona includes 14 species (De Grave & Fransen 2011), O. lopheliae sp. nov. differs from 12 species of the genus in having the posterior half of carapace behind cervical groove cincture smooth. Odontozona edwardsi and Odontozona spongicola are close related with O. lopheliae sp. nov. sharing the feature mentioned above. Odontozona edwardsi is easily separated from O. lopheliae and O. spongicola by the transverse grooves on the first three abdominal pleomeres, dorso-tranverse carina on the sixth pleomere, and the posterior pleural teeth versus the smooth pleon of these two species. Odontozona spongicola lacks the spinous propodal margins of the third perieopods (Goy 1992) seen in O. edwardsi and O. lopheliae. The other deep water Pacific species, O. foresti Hendrickx, 2002, lacks the spination of the third pereiopods and telson seen on O. edwardsi and O. lopheliae. As mentioned above, the remaining Atlantic species of Odontozona are much more spinous on the carapace, abdomen, and appendages of both O. edwardsi and O. lopheliae. Atlantic Odontozona are distributed as follows: Odontozona striata Goy, 1981 and O. meloi Anker & Tavares, 2013 are known only from their respective holotypes, the first sampled in deep waters off Cape San Antonio, Cuba and the latter sampled on Brazilian continental shelf (off Espírito Santo state) at a depth of 81.6 m. Odontozona minoica Dounas & Koukouras, 1989 is a deep-water species known from 125 m and 300 m in Aegean Sea off Crete (Koukouras & Dounas 2000). Besides that, two of the Atlantic species are restricted to shallow waters: Odontozona libertae Gore, 1981 presently known from 56 m off Key Largo, Florida and from 23 m in Granate Bay, Columbia (Criales 1997) and Odontozona anaphorae Manning & Chace, 1990, known only from the holotype from 10 m off Ascension Island in the South Atlantic Ocean. Odonotozona addaia Pretus, 1990 is presently known from a marine cave in the western Mediterreanean on the coast of Menorca at a depth of 5 m. The Atlantic species of Odontozona can be separated base on the key below. : Published as part of Goy, Joseph W. & Cardoso, Irene A., 2014, Redescription of Odontozona edwardsi (Bouvier, 1908) (Decapoda: Stenopodidea: Stenopodidae) and description of a new species of Odontozona commensal on the deep-water coral, Lophelia pertusa (Linneaus, 1758), pp. 552-566 in Zootaxa 3774 (6) on pages 558-565, DOI: 10.11646/zootaxa.3774.6.4, http://zenodo.org/record/4910070 : {"references": ["Becker, E.

(Fig. 8) An ovigerous female was photographed off Sapelo Island, Georgia (SERTC 1008) taken from a depth of 665 m.

Edges of third maxillipeds, first and second pereiopods red. Third pereiopods merus, carpus red; ischium, proximal propodus edged in red; distal propodus, dactylus white. Fourth, fifth pereiopods mostly whitish to transparent with few red spots along edges. Ovary and eggs blue. Development. Ovigerous females ranged in size from 5.2–5.4 mm postorbital carapace length, 18.1–18.4 mm total length and carried 10– 11 eggs. Eggs at blastula stage with undifferentiated yolk cells were 1.20 × 1.62 mm in size. Type locality. 22°24'12"S 46°06'18"W at Campos Basin, Rio de Janeiro, Brazil. Distribution: 31°386'N 78°6033'W off Sapelo Island, Georgia, USA; 27°35.89'N 91°49.60'W and 27°44.81'N 91°13.44'W Green Canyon, Gulf of Mexico. Habitat. The holotype was sampled at a deep sea coral reef at a depth of 621 m by means of a ROV (remotely operated vehicle). The species’ deepest record is from off Sapelo Island at 665 m. Six cruises from 2002 to 2005 recorded 84 specimens of the species by means of the deep-sea submersible Johnson-Sea-Link at primarily two locations, Green Canyon and Viosca Knoll in the Gulf of Mexico at depths from 459 to 525 m with an average depth of 489m. The use of deep-sea human operated orb remotely operated vehicles allowed the observation of the species’ association with live or dead coral branches of Lophelia pertusa , a foundation species that is found throughout the world’s oceans on topographic features (Rogers 1999). Etymology. The species is named for its association with the deep-sea coral Lophelia pertusa. Remarks. Both Odontozona edwardsi and O. lopheliae sp. nov. closely follow the definition of the genus Odontozona given by Holthuis (1946) and are most closely similar to each other as well as O. spongicola (Alcock & Anderson 1899) from deep water in the Pacific. The genus Odontozona includes 14 species (De Grave & Fransen 2011), O. lopheliae sp. nov. differs from 12 species of the genus in having the posterior half of carapace behind cervical groove cincture smooth. Odontozona edwardsi and Odontozona spongicola are close related with O. lopheliae sp. nov. sharing the feature mentioned above. Odontozona edwardsi is easily separated from O. lopheliae and O. spongicola by the transverse grooves on the first three abdominal pleomeres, dorso-tranverse carina on the sixth pleomere, and the posterior pleural teeth versus the smooth pleon of these two species. Odontozona spongicola lacks the spinous propodal margins of the third perieopods (Goy 1992) seen in O. edwardsi and O. lopheliae. The other deep water Pacific species, O. foresti Hendrickx, 2002, lacks the spination of the third pereiopods and telson seen on O. edwardsi and O. lopheliae. As mentioned above, the remaining Atlantic species of Odontozona are much more spinous on the carapace, abdomen, and appendages of both O. edwardsi and O. lopheliae. Atlantic Odontozona are distributed as follows: Odontozona striata Goy, 1981 and O. meloi Anker & Tavares, 2013 are known only from their respective holotypes, the first sampled in deep waters off Cape San Antonio, Cuba and the latter sampled on Brazilian continental shelf (off Espírito Santo state) at a depth of 81.6 m. Odontozona minoica Dounas & Koukouras, 1989 is a deep-water species known from 125 m and 300 m in Aegean Sea off Crete (Koukouras & Dounas 2000). Besides that, two of the Atlantic species are restricted to shallow waters: Odontozona libertae Gore, 1981 presently known from 56 m off Key Largo, Florida and from 23 m in Granate Bay, Columbia (Criales 1997) and Odontozona anaphorae Manning & Chace, 1990, known only from the holotype from 10 m off Ascension Island in the South Atlantic Ocean. Odonotozona addaia Pretus, 1990 is presently known from a marine cave in the western Mediterreanean on the coast of Menorca at a depth of 5 m. The Atlantic species of Odontozona can be separated base on the key below. : Published as part of Goy, Joseph W. & Cardoso, Irene A., 2014, Redescription of Odontozona edwardsi (Bouvier, 1908) (Decapoda: Stenopodidea: Stenopodidae) and description of a new species of Odontozona commensal on the deep-water coral, Lophelia pertusa (Linneaus, 1758), pp. 552-566 in Zootaxa 3774 (6) on pages 558-565, DOI: 10.11646/zootaxa.3774.6.4, http://zenodo.org/record/4910070 : {"references": ["Becker, E.
