Abstract

The first zoeal stages of ?Cataleptodius parvulus and Xanthodius denticulatus are described and compared with zoeae of other members of the subfamily Xanthinae. The larvae of ?C. parvulus and X. denticulatus differ mainly in: 1) spinulation of rostral and dorsal spines; 2) type of antenna; 3) setation of the basis of first maxilliped; and 4) type of telson. Features common to both species include a carapace provided with well-developed spines on the dorsal (1), rostral (1), and lateral (2) portions; and the antennal protopod and rostrum similar in length. The morphological differences between the zoea I of X. denticulatus and ?C. parvulus are nevertheless consistent enough to suggest that these species do not belong to the same genus Xanthodius Stimpson, 1859 as previously supposed. Also we presume that ?C. parvulus does not belong to the genus Cataleptodius.

摘要

描述了微小拟滞育蟹（Cataleptodius parvulus）和具齿黄蟹（Xanthodius denticulatus）的第一期溞状幼体阶段，并将其与黄蟹亚科其他成员的溞状幼体进行了比较。微小拟滞育蟹和具齿黄蟹的幼体主要在以下方面存在差异：1）额棘和背棘的小刺；2）触角类型；3）第一小颚足基部的刚毛；4）尾节类型。这两个物种的共同特征包括：头胸甲的背侧（1根）、额部（1根）和侧面（2根）有发育良好的棘；触角原节和额部长度相似。然而，具齿黄蟹和微小拟滞育蟹第一期溞状幼体之间的形态差异足够一致，表明这些物种并不像之前所认为的那样属于1859年斯廷普森（Stimpson）所定义的同一个黄蟹属（Xanthodius）。此外，我们推测微小拟滞育蟹也不属于拟滞育蟹属（Cataleptodius）。
