摘要

Synalpheus ubatuba zoea I 是通过评估实验室孵化的幼虫来描述的。并将其与文献中的其他 Synalpheus 描述进行了比较。分析了亲本雌虫 16S rRNA 的部分序列,为物种鉴定提供了更多证据。第一个 S.ubatuba zoea 可通过一系列形态特征进行鉴定,即:触角鳞片 4 节;上颌基部内侧具 3 个粗刺 + 1 个刺;上颌腋部内侧具 3 个羽状刚毛和 1 个单性刚毛;第一上颌基部具 4 个刺和 2 个单性刚毛;第三上颌内侧具 5 节,分别具 0、0、0、2(1 个锯齿 + 1 个单性)刚毛和 4 个单性刚毛。与 S. ubatuba 所属的 Brevicarpus 类(S. brevicarpus 和 S. minus)中的其他物种相比,这些特征在幼虫形态上存在明显差异。尽管在最初的 S. ubatuba 描述中提供了系统学和生态学信息,但本研究是首次关注该物种幼虫形态的特殊特征。本文提供的幼虫形态特征的证据,以及与提供著名幼虫描述的同属种的潜在比较,支持了对新发现物种的鉴定。

Life history of the snapping shrimp Synalpheus ubatuba: Morphological description of the first larval stage reared in laboratory
Synalpheus ubatuba zoea I was described by assessing laboratory‐hatched larvae. It was compared to other Synalpheus descriptions available in the literature. Partial sequences of parental female's 16S rRNA were analysed and it provided additional evidence for species identification. The first S. ubatuba zoea can be identified by a set of morphological characteristics, namely: antennal scale 4‐articled; basial endite of the maxillule with 3 stout spines + 1 spine; coxal endite of the maxilla with 3 plumose setae and 1 simple seta; basis of the first maxilliped with 4 spines and 2 simple setae; endopod of the third maxilliped with 5‐articled with 0, 0, 0, 2 (1 serrate + 1 simple) setae, 4 simple setae. There was significant larval morphology difference between these characteristics in comparison to other species in the Brevicarpus group (S. brevicarpus and S. minus) which S. ubatuba belongs to. Despite systematic and ecological information provided in the original S. ubatuba description, the present study is the first to focus on the particular features of this species' larval morphology. Evidence of the herein provided larval morphology traits in addition to potential comparison to congeners presenting well‐known larval descriptions, supported the identification of newly discovered species.

期刊介绍: Published regularly since 1920, Acta Zoologica has retained its position as one of the world''s leading journals in the field of animal organization, development, structure and function. Each issue publishes original research of interest to zoologists and physiologists worldwide, in the field of animal structure (from the cellular to the organismic level) and development with emphasis on functional, comparative and phylogenetic aspects. Occasional review articles are also published, as well as book reviews.
