摘要

对马铃薯属(Lacunipotamon Dai, Song, He, Cao, Xu & Zhong, 1975)的分类进行了修订。中国南方已知3种:L. albusorbitum Dai, Song, He, Cao, Xu & Zhong, 1975(模式种);黄元石，Shih & Ahyong, 2020;和L. cymatile Huang, Shih & Ahyong, 2020。本文描述了越南北部8个新种:globus L.、panda L.、contrastum L.、sublividum L.、mimum L.、thuanchau L.、pectum L.和purpureum L.。这是该属在越南的首次记录，所有新种均来自喀斯特地层。根据甲壳形状、前外侧枢椎、鼻甲后缘、雄性胸骨空腔、鳍足、活动腿、雄性胸骨、雄性pleon、雄性第一性腺和外阴结构等特征来区分。

Revision of the Genus Lacunipotamon Dai, Song, He, Cao, Xu & Zhong, 1975 (Crustacea: Decapoda: Brachyura: Potamidae), with Descriptions of Eight New Species from Vietnam.

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; and L. cymatile Huang, Shih & Ahyong, 2020. 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 by the characters of 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 and vulvae.
