Four species (<i>E. sternomaculata</i>, <i>E. annulosa</i>, <i>E. capillata</i>, and <i>E. parva</i>) are very common at depths between 400 and 600 meters, being currently caught at the same stations. The other species are scarce, and have been collected either at the same depths (<i>E. keijii</i>), or in shallower waters (<i>E. minor</i> and <i>E. marginata</i>). The high abundance of these species could be related to the presence on the bottom of hydrocorallians of the family Stylasteridae. Three species (<i>E. keijii</i>, <i>E. annulosa</i> and <i>E. sternomaculata</i>) belong to the group A after GORDON (1930), characterized by a spine on either side of the sternal segment bearing the chelipeds. The latter two of these species have a pad on the ventral surface of the palm. <i>E. keijii</i> is closely related to <i>E. pacifica</i> Gordon, 1930, from the south of Timor, but, among other differences, the two are readily distinguished by the size of the first hepatic spine, the median sinus of the third thoracic sternite and the scales on the sternal segments. <i>E. sternomaculata</i> resembles <i>E</i>. sp., from southeast Australia (<i>E. picta</i>, GORDON, 1930, in part) ; both ar nevertheless easily distinguished by the shape of th frontal part of the carapace, the direction of the supraorbital spines and the relative lengths of the anterolateral spines and antennal peduncles. <i>E. annulosa</i> is close to <i>E. sternomaculata</i>. These tWo species are differentiated by the shape of the rostral spines, the ornamentation of the carapace, the length and shape of the chelipeds and the presence or absence of a disto-mesial spine on the carpus of the chelipeds. <i>E. marginata</i>, <i>E. capillata</i>, <i>E. parva</i> and <i>E. minor</i> belong to the group B, after GORDON, that has no spine on either side of the sternal segment bearing the che1ipeds. With the exception of <i>E. parva</i>, all the other species are provided with a pad on the ventral surface of the palm. <i>E. parva</i> is closely related to <i>E. smithii</i> Henderson, 1883, from the south of Timor, and to <i>E. propior</i> Baba, 1988, from the Philippines. A discussion about the identity of the material of <i>E. smithii</i> from different expeditions and the relationships between the three species is provided. The males of these three species are characterized by the presence of pleopods on the second to fifth abdominal segments. <i>E. capillata</i> is very close to <i>E. parva</i>, but can be easily distinguished from it by a number of characters. The main difference is the presence of a pad on the ventral surface of the cheliped palm in <i>capillata</i>, and its absence in <i>parva</i>. <i>E. minor</i> is the smallest representative of the genus. The species is clearly distinguishable from all the others of the group B by the presence of two prominent spines on the merus of the third maxillipeds, and of four longitudinal rows of spines on the merus of the chelipd. Its closest relative is <i>E. balssi</i> Gordon, 1930. <i>E. marginata</i> is related to <i>E. gordonoae</i> Baba, 1973, from Japan. However, the length and the spinulation of the pereopods are very different.","AbstractOtherLang":"Le genre <i>Eumunida</i>, Galatheidea Chirostylidae, est représenté au large de la Nouvelle-Calédonie et dans l'archipel des Chesterfield par sept espèces au moins, toutes décrites comme nouvelles. <i>Eumunida sternomaculata</i>, <i>E. annulosa</i>, <i>E. capillata</i> et <i>E. parva</i> apparaissent comme très communes entre 400 et 600 mètres, et ont souvent été récoltées aux mêmes stations. Les trois autres ne sont représentées que par un petit nombre d'individus: quatre pour <i>E. keijii</i>, recueillie sur les mêmes fonds que les précédentes, sept pour <i>E. minor</i> sp. nov., récoltée de 230 à 274 mètres, et un seul pour <i>E. marginata</i>, proche d'<i>E. gordonae</i> Baba, 1976, provenant de 330 mètres. La description des espèces est complétée par leur comparaison entre elles et avec les autres espèces in indo-ouest-pacifiques du genre. Quelques indications sont données sur le developpement des <i>Eumunida</i>, qui, à l'inverse de celui des autres Chirostylidae où il est connu, comprend une phase pélagique, analogue à celle de nombreux autres Décapodes. L'abondance exceptionnelle des <i>Eumunida</i> dans région étudiée pourrait être liée a celle, également remarquable, des Hydrozoaires de 1a famille des Stylasteridae.","BibLvlCode":"AMS","StandardTitle":"Crustacea Decapoda: le genre <i>Eumunida</i> Smith 1883 (Chirostylidae) dans les eaux néo-calédoniennes","OrigTitleLangCode":"fr","OrigTitleLangCodeExtended":"fre","OrigTitleLangID":22,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1990,"MonPub":null,"DateUpdate":"2017-01-04","DateCreate":"2001-05-15","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":9046,"PubliDate":1990,"Pagination":"227-288","XtraPublOfAnaID":null,"ISBN":"2-85653-171-7","Volume":"145","Issue":null,"BRefMon":8848,"BRefMonRR":"<b>Crosnier, A.
