Tweedieia属的黄蟹是印度-西太平洋珊瑚礁中最美丽的十足类隐动物群之一，具有华丽的颗粒和刚毛排列，并具有引人注目的颜色图案。该属和3个已知种（T. odhneri，T. laysani和T.短趾龙属）进行了修订，并提供了新的诊断和数字。对38份标本的COI条形码基因进行测序，并用于构建最大似然树和邻接树。Tweedieianow仅包括两个种，Tweedieiodhnerirans分布于西印度洋至夏威夷群岛和法属波利尼西亚，而Tweedieiodhnerirans分布于西印度洋至夏威夷群岛和法属波利尼西亚。雷桑虫只在夏威夷群岛有记录。这些螃蟹似乎喜欢清澈，寡营养，海洋沃茨，是常见的海洋岛屿和罕见的大陆和大洋洲的大岛周围。
Xanthid crabs of the genusTweedieia, are among the most beautiful decapod cryptofauna in Indo-West Pacific coral reefs, with an ornate arrangement of granules and setae, in combination with an eye-catching color pattern. The genus and three recognised species (T. odhneri,T. laysani, andT. brevidactyla) are revised, and new diagnoses and figures are provided. The COI barcoding gene of 38 specimens was sequenced and used to generate maximum likelihood and neighbor-joining trees.Tweeedieia brevidactylais here synonymized withT. odhneri.Tweedieianow comprises only two species, differentiated by morphological characters and sequence data.Tweedieia odhneriranges from the western Indian Ocean to the Hawaiian Islands and French Polynesia, while the rareT. laysaniis only recorded from the Hawaiian Islands. These crabs appear to favor clear, oligotrophic, oceanic waters and are common on oceanic islands and rare around continents and large islands of Australasia.
