The taxonomy of the potamid genus Lacunipotamon Dai, Song, He, Cao,
Xu & Zhong, 1975, is revised. Three species are known from southern
China: L. albusorbitum Dai,
Song, He, Cao, Xu & Zhong, 1975 (type species); L. yuanshi Huang, Shih &
Ahyong, 2020, L. cymatile
Huang, Shih & Ahyong, 2020; and eight new species are here
described from northern Vietnam – L.
globus, L. panda, L. contrastum, L. sublividum, L. mimicum, L. thuanchau, L. pectum and L. purpureum. This is the first
record of the genus in Vietnam, with all the new species obtained from
karst formations. The species are differentiated on characters of the
carapace shape, anterolateral armature, posterior margin of the
epistome, male sternopleonal cavity, chelipeds, ambulatory legs, male
thoracic sternum, male pleon, and structures of the male first gonopods
Key words: Potamoidea, New
