New species of squat lobsters of the genera Munida and Raymunida (Decapoda, Galatheidae) from Vanuatu and New Caledonia

Abstract

[FR]Sept espèces nouvelles des genres Munida Leach, 1820 (M. acola n. sp., M. clevai n. sp., M. jubata n. sp., M. mica n. sp., M. pauxilla n. sp., and M. squarrosa n. sp.) et Raymunida Macpherson & Machordom, 2000 (R. vittata n. sp.) provenant du Vanuatu et de Nouvelle-Calédonie, sont décrites et illustrées. Munida acola n. sp. se caractérise par le second segment abdominal inerme, des épines distales de taille inégale sur les pédoncules antennulaires, et les dactyles des P2–P4 possédant des épines tout le long de leur bord ventral. Munida clevai n. sp. possède de petits yeux et des épines sur la ride antérieure du second segment abdominal. Munida jubata n. sp. est caractérisé par la présence d'épines sur le second segment abdominal et par la taille inégale des épines distales des pédoncules antennulaires. Munida mica n. sp. et M. pauxilla n. sp. ont le bord frontal de la carapace oblique, des segments abdominaux inermes et des épines distales des pédoncules antennulaires de taille inégale. Munida squarrosa n. sp. possède des épines sur le second segment abdominal et la moitié distale du bord ventral des dactyles des P2–P4 inerme. Raymunida vittata n. sp. appartient à un groupe d'espèces possédant l'épine mésiale du premier segment antennaire n'atteignant pas la fin du segment basal du pédoncule antennulaire, et l'articulation méro-carpal du P4 atteignant presque la marge frontale de la carapace.

[EN]Seven new species of the genera Munida Leach, 1820 (M. acola n. sp., M. clevai n. sp., M. jubata n. sp., M. mica n. sp., M. pauxilla n. sp. and M. squarrosa n. sp.) and Raymunida Macpherson & Machordom, 2000 (R. vittata n. sp.) are described and illustrated from specimens collected during recent cruises carried out off Vanuatu. Munida acola n. sp. has the second abdominal somite unarmed, distal spines of the antennular peduncle unequal in size, and the P2–P4 dactyli with spines along the entire ventral border. Munida clevai n. sp. has small eyes, and spines on the anterior ridge of second abdominal somite. Munida jubata n. sp. is characterized by the presence of spines on the second abdominal somite, and unequally sized distal spines of antennular peduncle. Munida mica n. sp. and M. pauxilla n. sp. have the frontal margin oblique, abdominal somites unarmed, and distal spines of antennular peduncle of different size. Munida squarrosa n. sp. has the second abdominal segment with spines, and the distal half of the ventral border of P2–P4 dactyli unarmed. Raymunida vittata n. sp. belongs to a group of species having the mesial spine of first antennal segment not reaching the end of the basal segment of antennular peduncle, and mero-carpal articulation of P4 nearly reaching the frontal margin of the carapace.
