Abstract
The poorly known genus Lacunipotamon Dai, Song, He, Cao, Xu & Zhong, 1975, is studied and reviewed. Two new species, Lacunipotamon yuanshi sp. nov. and Lacunipotamon cymatile sp. nov. from Yunnan Province and Guangxi Zhuang Autonomous Region, respectively, are described based on morphology and mitochondrial cytochrome c oxidase subunit I (COI) sequences. Both superficially resemble Lacunipotamon albusorbitum Dai, Song, He, Cao, Xu & Zhong, 1975, the type and previously only known species in the genus, but can be distinguished by the combination of live colour, size, maxilliped III, male thoracic sternum, male pleon, male gonopod, and female gonopore characters. Phylogenetic analysis of the molecular data corroborates the novelty of the two species.
Résumé
Le genre peu connu Lacunipotamon Dai, Song, He, Cao, Xu & Zhong, 1975, est étudié et revu. Deux nouvelles espèces Lacunipotamon yuanshi nov. sp. et Lacunipotamon cymatile nov. sp. respectivement de la province du Yunnan et de la région autonome Guangxi Zhuang, sont décrites sur la base de leur morphologie et des séquences de la sous-unité de l’oxydase du cytochrome c mitochondrial (COI). Les deux ressemblent approximativement à Lacunipotamon albusorbitum Dai, Song, He, Cao, Xu & Zhong, 1975, le type et la seule espèce du genre connue jusqu’alors, mais peuvent être distingués grâce à la combinaison de leur couleur sur le vivant, la taille, le maxillipède III, le sternum thoracique, le pléon, les gonopodes chez le mâle et les gonopores femelles. L’analyse phylogénétique des données moléculaires corrobore la nouveauté des deux espèces.
