The complete larval development of the hermit crab Pagurus maculosus, is described and illustrated based on specimens reared in the laboratory at 15 °C and 33-35 PSU. Newly hatched larvae invariably passed through a short prezoeal stage (10 minutes to 2 hours), four zoeal stages (each of 7 days,) and one megalopal stage (14 days). Distinct morphological features of each larval stage of the present study are compared with other closely related species in Japanese waters, and we found many differences in morphology and the duration of zoeal stages between them. We mentioned significant diagnostic characters separating this species from other congeners in Japanese waters that include the presence of red-yellowish chromatophores on the maxillipeds. This is the first report of complete larvae development of Pagurus maculosus.
基于在15°C和33 - 35盐度下在实验室饲养的标本，描述并说明了红斑陆寄居蟹（Pagurus maculosus）的完整幼体发育过程。新孵化的幼体总是会经过一个短暂的前溞状幼体阶段（10分钟至2小时）、四个溞状幼体阶段（每个阶段7天）和一个大眼幼体阶段（14天）。本研究中每个幼体阶段的明显形态特征与日本海域其他近缘物种进行了比较，我们发现它们在形态和溞状幼体阶段的持续时间上存在许多差异。我们提到了将该物种与日本海域其他同属物种区分开来的重要诊断特征，包括在颚足上存在红黄色色素细胞。这是关于红斑陆寄居蟹完整幼体发育的首次报告。
